Stormwater Monitoring NPDES Details

stormwater monitoringIn our original blog article entitled “Florida NPDES Stormwater Requirements”, we provided an overview of these regulatory requirements.  In this current article, we will provide more details on the monitoring itself.  These monitoring requirements apply to stormwater runoff leaving your site.  This may be a single outfall or more than one outfall.  If there is no outfall, you may have to construct one to collect runoff to monitor.

What is stormwater monitoring?  It is the evaluation of the water leaving your site as stormwater runoff.  To perform this evaluation, a sample must be collected.  The evaluation may either be done visually or analytically in a laboratory.  Your permit may just require visual monitoring for all five years of your permit, or it may require that in years one, three, and five, plus analytical monitoring in years two and four.  Note that Florida Department of Environmental Protection (FDEP, www.myflorida.com) uses calendar years, so that if your permit is issued anytime between January 1st and December 31st in a given year, that is counted as year one.  Thus, year two of your permit will start January 1st of the next year, even though a full year (i.e., 365 days) has not passed.

Regardless of the type of monitoring, you must measure and keep a log of rainfall on site.  This has to be done prior to the beginning of the quarter so you can identify the last qualifying rainfall event and it continues until you monitor a qualifying event in the current quarter.  A qualifying rainfall event is greater than one-tenth of an inch (0.1 in).  For monitoring, the event has to be preceded by no qualifying events within 72 hours.    Measuring rainfall can either be done manually or automatically with a tipping rain gauge recording unit.

Visual monitoring is done by collecting a sample in a clean glass container (clear and at least sixteen ounces is best).  The sample is then examined for clarity, sediment, oily sheens, other pollutants, and foam.  All information should be recorded on a form in your Storm Water Pollution Prevention Plan (SWPPP).  Included with the sample evaluation data are the Sampler’s name and signature, date, time, start and stop times of the runoff event, and location of the outfall sampled.  This form must be kept in the SWPPP.

Analytical monitoring will be dictated by your permit.  The pollutants or parameters to be analyzed in the laboratory will be identified.  Additionally, the regulatory limits for each parameter will be shown.  It is important that the analyses be done in a laboratory accredited by National Laboratory Environmental Accreditation Program, NELAP (www.nelac-institute.org) and be certified by the Florida Department of Health (www.floridahealth.gov).  The same information concerning the visual sampling above is recorded and a Chain-of-Custody form is completed to accompany the samples to the laboratory.  This information and the lab results are kept in the SWPP.

Samples for laboratory analysis must be handled properly to insure accurate results.  The samples may need to be preserved or iced or both.  If they are not delivered immediately to the laboratory, they must be held in a refrigerator at no more than forty degrees Fahrenheit where the temperature is recorded on a written log daily.  Samples must be analyzed before their hold time expires.

The visual and analytical results must be evaluated.  If there is a problem, you must determine the likely cause and take corrective action.  This should be documented in your SWPPP and, for analytical results, on your Discharge Monitoring Report (DMR) filed with the FDEP by March 1st following the monitoring year.

Florida National Pollutant Discharge Elimination System Stormwater Requirements

The U.S. Environmental Protection Agency (EPA, www.epa.gov) established the National Pollutant Discharge Elimination System (NPDES) program back in the 1970’s to meet the requirements of the federal Clean Water Act.  The initial focus was on point source discharges from industrial facilities.  In the early 1990’s, EPA was forced to address nonpoint sources which was stormwater runoff from certain municipalities, industrial plants, and construction sites.  After several years the Florida Department of Environmental Protection (FDEP, www.myflorida.com) took over the program from EPA.  The focus of the rest of this article will be on the requirements for stormwater runoff for industrial facilities.

Industrial facilities included are manufacturers and those with Standard Industrial Classifications (SIC) 20 through 45, 50, and 51, plus power plants, mining operations, recycling facilities, and transportation facilities.  Others include landfills, mines, hazardous waste facilities, and junkyard facilities.  Industrial areas or operations which could impact stormwater include material storage, access roads, and rail lines, manufactured and intermediate product storage, material handling equipment storage, and maintenance areas.  Drums or tanks of solvents, oils, and chemicals are included as are open dumpsters, air compressors, and material handling areas outside.  Facilities are covered if their stormwater runoff discharges directly or ultimately to navigable waters of the U.S.  In Florida, this applies to most sites.

So if you have any sources of pollutants which could be entrained in the stormwater runoff, what do you do?  First, file a Notice of Intent to be covered under the General Permit.  A fee of $500.00 must accompany the form, which is for the five years of permit coverage.  Next, you must prepare a Storm Water Pollution Prevention Plan (SWPPP) and implement it.

Finally, quarterly visual monitoring of the stormwater runoff will have to be completed for the life of the permit.  Additionally, for certain SIC Codes, in years 2 and 4 of the permit, samples will have to be analyzed in an analytical laboratory.  Analytical results must be reported to FDEP by March 1st of the year following monitoring.  In certain cases when the analytical results for year 2 of the monitoring are in compliance, the FDEP may waive entirely or partially the year 4 analytical monitoring requirements.

A side note is that monitoring is required twenty-four hours a day, seven days a week.  The regulations do not stipulate that it is only required during normal business hours.  It is imperative that you make every reasonable effort to complete monitoring during each calendar quarter.  The FDEP has access to rainfall records for your area.

Like a lot of environmental regulatory programs, documentation is key.  That includes your Notice of Intent, payment of the fee, Storm Water Pollution Prevention Plan, Training, monitoring, and reporting.  Included in the monitoring is logging rainfall measurements daily which is key to monitoring stormwater runoff.

So now you know what the requirements are for Florida’s NPDES Stormwater program for industrial facilities.  If you need any more information, Environmental Safety Consultants (www.escflorida.com) can assist.  We have the credentials and experience to answer your questions and steer you in the right direction.  We are a Florida-licensed Engineering business with over thirty-five years of stormwater experience.  We are just a telephone call (800-226-1735) or an e-mail away ([email protected]).  Contact us today!

An Introduction to Mold Assessments

In our first blog article on mold, we explored Mold Myths.  In the next one, we provided a general description of Mold Assessments.  Now, we will take those Assessments to the next level.  That is, we will go into more detail on how the information and data are interpreted and what the conclusions may be.  Keep in mind that while these Assessments are based on published scientific literature and guidelines, they remain the professional opinion of Environmental Safety Consultants, Inc. (ESC).

There are several areas of the Assessment that will be addressed in this article.  These include moisture content, inspection findings, on site (in situ) readings, laboratory results on various types of mold samples, and interview information.  Keep in mind that the Assessment needs to be conducted by a Florida-licensed Mold-Related Services Assessor (MRSA) not also serving as the Florida-licensed Mold-Related Services Remediator.  For a lot of reasons, and certainly if there is a potential for litigation, you may want to make sure the MRSA is also a Certified Industrial Hygienist (CIH, see www.abih.org).  You can also find CIHs in the Consultants Directory (www.aiha.org).

Mold AssessmentsFurther details on the moisture content of building materials are provided here.  Remember that the thermal imaging camera is used to identify materials that are cooler, perhaps due to the evaporation of water.   A moisture meter is then used to confirm or refute the presence of water.  These meters can be used in the survey or penetrating mode.  In the survey mode, readings are taken from the surface of the build-ing material, whereas in the penetrating mode, pin holes or larger holes are made and the readings are taken at a certain depth.  The readings are usually standardized to a common unit, such as wood moisture equivalent (WME).  Readings of 16 to 20% WME are considered borderline moist while those exceed-ing 20% WME are usually considered excessively moist.  This level of moisture is capable of supporting the growth of mold.  Thus, if this level is found, mold could be present in the building material, wall cavity air, etcetera.

Surface samples are of two basic types – cello-tape or sticky tape samples and swab samples.  Both types collect living, dead, and dormant mold.  Both can be analyzed directly under the microscope in a third party laboratory accredited by the American Industrial Hygiene Association (AIHA).  The examination evaluates the sample for the genuses or genera of mold, percent coverage, and growth structures present.  ESC usually has the swabs streaked on nutrient agar plates (i.e., Petri dishes) in the laboratory.  They are then held under controlled conditions and evaluated for the genuses or genera of mold, percent coverage, and extent of growth (Colony FormingUnits or CFUs).  Whatever the analysis is, ESC uses internal criteria to determine if significant mold contamination is present.

Spore traps collect living, dead, and dormant mold in the air.  The genera of mold, concentration (counts or spores per cubic meter), and growth structures are reported. ESC typically compares these results to those for two outside air samples collected on different sides of the building.  Total concentrations of all mold, concentrations for each genus, and genera indicating wet or damp conditions are compared.  If several wet or damp indicators are found inside, the concentrations inside are much greater than outside, and if the diversity of the population is different inside, this may indicate unique conditions, and, thus, significant mold contamination.

Nutrient agar plate samples collect living mold spores with a sampling device such as an Anderson 1-stage microbial impaction device.  The plate is then allowed to grow under controlled conditions in the laboratory for 5 to seven days, then evaluated.  Comparison to outside plate samples and interpretation is the same as for spore trap samples.

ESC then evaluates all results – inspection, interview, in situ readings, and laboratory results to prepare the report.  Six to seven criteria are used to interpret the laboratory data.  The laboratory results are only part of the story, though.  Equally important are the inspection results, in situ readings, and interview information from the building occupants and owner.  The report provides details on the testing, results, conclusions and recommendations.  The report may include a Remediation Protocol (a cleanup plan).  ESC submits the report to the client and is available for discussion as required.

Mold Myths Revealed

Environmental Safety Consultants (ESC) has been in the Indoor Air Quality field for thirty years and heard many myths concerning mold from clients, other assessors, and remediators.  These mold myths have included the definition of mold, testing techniques, and remediation procedures.  We will review some of the more notorious myths in this article.

Before delving into mold myths let’s begin with what mold is.  It is not a plant or an animal.  It is a microscopic organism that is in the fungi kingdom.  Its official name is fungus (singular) or fungi (pleural).  Included in that kingdom are mushrooms.  Another myth is that you don’t have to worry about mildew.  That is wrong because it can cause sneezing, coughing, and upper respiratory ailments (www.cdc.gov), just like mold can.  From this point forward, we will use the term mold for mildew and mold.

mold mythsAnother myth is concluding no mold is present in the air or on surfaces because you can’t see it.  Mold is microscopic until it forms layer upon layer of organisms (a colony) and becomes visible to the unaided eye.  The spores in the air and the organisms on surfaces of building materials and contents are invisible until they are put under the microscope or grown out in the lab on nutrient agar plates – otherwise known as Petri dishes.

A very common myth is that as long as the “black toxic mold” is not present, I don’t have to worry.  Ah, if life were so simple!  Unfortunately, when you dig into the scientific literature, a lot of different types of mold (genuses or genera) can cause health problems for people.  One example is Aspergillus, which can grow into a fungal ball in your lungs resulting in a debilitating disease known as aspergillosis.

Another myth is that mold is everywhere in Florida and you don’t have to worry about it if it grows in your residential or commercial building.  True, mold is everywhere but when it becomes way more concentrated in your home, starts destroying your building materials, and you start having health problems which clear up when you leave the building, it is time to act.  Oh, and by the way, it also does well in other climes whenever enough water is present.

The final myth is that remediation is supposed to eliminate all mold in the building.  Not true.  The objective is to return a mold infested building to normal mold conditions.  Sterile, that is the total absence of mold is not realistic and is, certainly, not sustainable.  As soon as the door is opened, the air conditioning or heating system kicks on, or mold spores are carried into the building on your shoes, the building is no longer sterile.

So there are a few of the mold myths that are out there.  If you need any more information, Environmental Safety Consultants (www.escflorida.com) can assist.  We have the credentials and experience to answer your questions and steer you in the right direction.  We are a Florida-licensed Engineering business with three Florida licensed Mold-Related Services Assessors, and a Certified Industrial Hygienist (CIH, American Board of Industrial Hygiene, www.abih.org).  We are just a telephone call (800-226-1735) or an e-mail away ([email protected]).  Contact us today!

 

Introduction to Contamination Assessments

Contamination AssessmentsThat is what Contamination Assessments used to be called in Florida.  But then they were renamed Site Assessments, which can be confused with Environmental Site Assessments (Phase I and II – see our other blog articles specific to those types of projects).  To avoid confusion, we will stick with the name Contamination Assessment (CA).  They became regulatory requirements in Florida in the 1980’s to primarily address contamination from underground and above ground fuel and oil storage tanks.  These CAs are required when contaminant levels in the soil or groundwater exceed the State Cleanup Target Levels.  They are designed to determine the extent of contamination in the soil and groundwater both horizontally and vertically.  Often, the contamination is originally discovered during tank closure, after a leak, from a spill, etcetera.

Which regulatory agencies require the CAs?  The lead agency is the Florida Department of Environmental Protection (FDEP, www.fdep.gov).  However, several counties (primarily the larger urban centers) have a contract to administer the cleanup program for the FDEP.  To determine if that is the case for your site, contact the district office of the FDEP which governs your county.

Which regulation requires CAs?  Chapter 62-780 of the Florida Administrative Code (F.A.C.) does.  All the detailed requirements are provided in that rule.  For questions, contact the FDEP or county administering the cleanup program.  The actual scope of work depends on the situation.  Certain things affect the scope such as level of contamination, type of petroleum product, history, action taken to clean it up, and whether the soil, groundwater, or both are affected.  Action taken could involve initial response, pumping out product, limited soil removal, and more.

Details of CAs will be discussed in another blog article.  Just be warned that CAs usually take time.  There are certain periods of time required to complete each step.  You are given deadlines to complete things and the regulatory agencies have deadlines to review and respond to each document or response you submit.  The whole process can easily drag into a year or more.

But for the moment, let’s say you have finished your CA and submitted it to the FDEP or county.  What are the potential outcomes?  First, additional work (i.e., more testing, information, or clarifications) may be required.  Next, let’s say you hit the lottery and you receive approval for No Further Action – you are done!  Alternatively, you do not hit the lottery and a Remedial Action Plan is required, followed by Remedial Action, and of course, another report.  Finally, there is a low level of contamination which results in potential natural attenuation (the site cleans up on its own).  In that case, you are required to complete Natural Attenuation Monitoring, which is done at regular intervals during each year for a two year or longer period of time.

So there you have it – a very brief introduction to Contamination Assessments in Florida.  If you need any help, Environmental Safety Consultants (www.escflorida.com) can assist.  We have the credentials and experience to answer your questions and steer you in the right direction.  We are a Florida-licensed Engineering business with a Professional Engineer (P.E.), environmental scientists, and 30 years of experience completing CAs.  We are just a telephone call (800-226-1735) or an e-mail away ([email protected]).  Contact us today!

Why All The Fuss With Asbestos?

asbestos suitWell, the fuss with asbestos all comes down to health risks.  Some of the potential outcomes are very serious – lung cancer, mesothelioma (i.e., cancer of the lining of the chest cavity), and asbestosis (a pulmonary obstructive disease that eventually puts such a strain on the lungs and heart, that the patient dies from cardiac arrest).  The primary route of entry for these extremely small asbestos fibers is inhalation.  Theoretically, these diseases can be caused by one exposure episode.  However, the greater the dose, the greater the disease.  And, finally, the diseases do not show up for ten to thirty years after the exposure.  That is a very long latency period.

There are many misconceptions about asbestos.  First of all, it is not just the ship workers who were exposed to it during World War II.  Second, one does not have to be in a dusty asbestos cloud to experience an exposure resulting in disease.  And, finally, it has not been asbestos testingbanned from all materials in the United States.  It has been banned in five to seven materials and it is still found in building materials being imported today.  It is not always listed on the material, sometimes a label states that a product is non-asbestos when it is not, and sometimes it is labeled as asbestos free, but chrysotile (the most common type) is listed on the ingredients).

The mining of asbestos and manufacture of asbestos containing building materials represents potential exposure to the personnel involved.  And sometimes, the workers bring the fibers home on clothing and shoes to their families.  This reportedly occurred in Libby, Montana where asbestos was mined (www.pbs.org/pov/libbymontana).

So, which materials can contain asbestos?  The U.S. Environmental Protection Agency (EPA, www.epa.gov) has a list of building materials suspected of containing asbestos.  It virtually includes everything except glass, metal, and wood.  Asbestos was added to thousands of materials due to its fire resistance, added strength, and chemical resistance.  It is a relatively inexpensive naturally occurring mineral which was added to nearly all building materials, plus brake linings, concrete, cement drinking water pipes, and gaskets.  It was used for fireproofing in schools, hospitals, airports, nursing homes, and other public and private installations and facilities.

asbestos workersFinally, workers who install, remove, or demolish it in buildings are at risk.  That is why EPA requires testing for asbestos before all renovations and demolitions of most buildings before the work is started.  If asbestos is present, certain abatement procedures will be required before the construction or demolition work begins.

But there is no reason to fuss.  Environmental Safety Consultants, Inc. (www.escflorida.com) can help.  We have the credentials and experience to properly complete your Asbestos Survey.  We have accredited Asbestos Surveyors and a Florida Licensed Asbestos Consultant (LAC) on staff.  We are a Florida-licensed Asbestos Business Organization with over thirty years of experience in the asbestos field.  We prepare abatement specifications, monitor abatement projects, and complete air clearance monitoring.  Whatever your asbestos needs are, just call us (800-226-1735 or one of our area office local numbers listed on our home page) or e-mail us ([email protected]).  Contact us today and get rid of the fuss!

Phase II Environmental Site Assessments

So you had your Phase I Environmental Site Assessment (Phase I) done and Recognized Environmental Conditions (RECs) were found.  You have decided to proceed with the transaction but you now need a Phase II ESA (Phase II) to fulfill your due diligence in determining if the site is or could be contaminated from usage of the site or properties in the vicinity.  On the financial end, you and the seller have decided who will pay for the Phase II.  This could mean that the seller will pay for it all, you will pay for it all, or the two of you will share the expense.  Many times if you are paying any part of it, there is a proviso that the seller will reimburse you in full if contamination is found and you cancel the trans-action.  The specifics are provided by your attorney.

The next step is to retain an environmental consulting firm to complete the Phase II.  It may be the same firm that did the Phase I or a different firm.  Not all Phase I firms complete Phase II’s.  Qualifications, licenses, availability, and a myriad of other considerations may result in switching firms.  However, if all things are equal, it is best to stick with the firm that did the Phase I.  The reason is that they are most intimately involved in both the assessment of the site and the basis for the RECs they reported.

Whichever firm you select, there are a number of items to check out.  You need to know how experienced they are in completing Phase II’s in general and, more specifically, in completing them on similar properties and similar contaminants.  Ask for a Statement of Qualifications & Experience which will list Phase II projects completed, resumes of the staff, and engineering or geological licenses with the State of Florida.  You can check these licenses out at www.myfloridalicense.com.

Phase IIOnce you have selected a firm, discuss the Scope of Work, turnaround, and terms.  The Scope should be designed to specifically investigate the RECs that were found during the Phase I.  This includes the media type and the contaminant types.  The media may include soil, surface water, sediments, and groundwater.  One or more of these media may need to be included.  Types of contaminants include gasoline, diesel fuel, used oil, solvents, pesticides, heavy metals, and perc (perchloroethylene, a dry cleaning chemical), among others.  There may be concerns with different contaminants in different locations on the site.  These locations may have different media to be tested.

The Scope of Work should follow Standard Operating Procedures of the Florida Department of Environmental Protection (FDEP) for quality assurance and control. Additionally, make sure the firm is using a laboratory accredited by the National Environmental Laboratory Accreditation Program, NELAP (www.nelac-institute.org) and certified by the Florida Department of Health (www.floridahealth.gov).  Otherwise, the data may not be court defensible or accepted by regulatory agencies in the event that those agencies become involved with the site.  Similarly, make sure that if a Well Driller is involved that they are licensed by the FDEP (www.fdep.gov).

After all of this is done, request a Professional Services Agreement from the firm.  This is the written contract between you and that firm.  It must spell out the basis for the Phase II, the turnaround, Scope of Work, and Terms & Conditions.  Review it closely and make sure it meets your satisfaction.  Otherwise, request revisions before you sign it.

So you have retained the firm, they are ready to start the project, and you are done, correct?  Not so fast.  When you give them notice to proceed, you need to request that they keep communications open.  Tell them that you want to know when the site work is scheduled, what the results are from the site work, what the significance of those results are, and what the analytical results from the laboratory are and what they mean. You may need to notify the seller of any significant findings as the work progresses.  Finally, let the firm know that you need the report at the time specified in the Agreement.

Once you receive the report, review it closely, then call or meet with the firm to answer any questions or clarify certain sections.  Keep in mind that there is no requirement to have the report submitted and approved by environmental regulatory agencies.  However, some lenders and other entities use other environmental consulting firms or attorneys to conduct peer reviews of the reports.  If significant contamination is found, then you or the seller should explore remediation options, which are the topic of another paper.  At that point, you may cancel the transaction and look for another site.  Your attorney must advise you.

Phase I Environmental Site Assessments Can Save You

There are certain extremely important environmental considerations in commercial property transactions. The soil, groundwater, or surface water, may be contaminated with pollutants such as solvents, PCBs, dry cleaning fluids, petroleum products, pesticides, arsenic, etcetera. There may be buried drums or tanks of pollutants. Or a retention pond may be part of an industrial wastewater treatment system and may be leaking pollutants into the aquifer affecting nearby residents.environmental site assessment

The conditions above may create an economically significant, environmental liability for you as the buyer. Once you enter into the chain of ownership, you are potentially liable for cleanup costs in the future. That is called joint and several liability in legalese and it could bankrupt a business, cause a default on the loan, and affect the market value of the property.

However, the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, aka Superfund, www.epa.gov/superfund) offers protection to the “innocent purchaser”. To qualify, a purchaser must exercise “due diligence” in determining whether a site is or could be contaminated. This is done by completing an Environmental Site Assessment (ESA) prior to the property transaction. The ESA is designed to determine if the property is or could be contaminated from past or current operations both on the site itself or on properties in the vicinity.

phase 1 assessment Environmental Site Assessments are conducted in phases. A Phase I ESA includes an inspection of the site and properties in the vicinity; review of environmental regulatory records, data, permits, and complaints; interviews of the buyer, seller, managers, and regulatory personnel; review of current and historical aerial photographs of the site and vicinity; review of environmental title search back to 1940; and review of nearby landfills, surface waters, and U.S. Geological Survey (USGS) topographical maps.

If the Phase I concludes that the site does not appear to be contaminated, you are done and can move on with the transaction. However, if it indicates that the site is or could be contaminated, then a Phase II ESA will be needed to test the soil, surface water, and groundwater to conclude the due diligence. But that is the topic of another paper.

The key to the ESA is exercising due diligence. Most purchasers of commercial properties retain environmental consulting firms to complete the ESA. Extreme care must be exercised in selecting the firm. It is not a situation where a penny saved is a penny earned. It can be more like a few hundred dollars saved can be thousands to millions of dollars lost.

As a consumer, you must make sure that the consulting firm has the experience, credentials, and qualifications to properly complete the ESA. This applies to the firm itself and to the actual staff members completing the ESA. Highly qualified principal consultants in offices miles away and not actually completing the ESA are of limited to no use.

Desired qualifications may include Professional Engineers, certified Environmental Site Assessors, and Professional Geologists. Of course, appropriate insurance coverage is a must. Check for inclusion of commercial general liability, professional liability, pollutant liability, workers compensation, and automobiles.

There is no requirement to have the ESA Reports submitted and approved by environmental regulatory agencies. However, some lenders and other entities use other environmental consulting firms or attorneys to conduct peer reviews of the Reports.

There are two ways that Environmental Site Assessments can help you. First, they can help you avoid acquiring contaminated properties. Second, if the ESA is completed properly and due diligence is exercised, Superfund is supposed to fund the cleanup if contamination is found later that could not be detected during the ESA. Ultimately, due diligence would be determined by the U.S. Environmental Protection Agency (EPA, www.epa.gov) or the courts.

Groundwater Environmental Monitoring

One type of environmental monitoring is groundwater testing.  This sounds simple enough, but exactly what is groundwater testing?  Well, let’s break apart the term.Groundwater Environmental Monitoring

First, groundwater is water that is beneath the surface of the earth, as opposed to surface water which is on the surface of the earth.  Sometimes, it is referred to as well water, the water table, or the aquifer. It is the source of water for springs.

Second, testing takes many forms.  It can be done with the unaided eye, depth measurement tools, electronic meters, or samples analyzed in a laboratory.  Testing done in the groundwater itself or on samples in the field is called in situ testing.

Samples can be collected manually or with automated samplers.  Manually collected samples can be collected with bailers, bladder pumps, centrifugal pumps, or peristaltic pumps directly into laboratory sample bottles.  The contents are then emptied into laboratory sample bottles.

Automated samplers can be programmed to collect samples at select time intervals over an extended period of time.  Separate samples can be collected at each time interval or sample aliquots can be collected at each time interval and then be added to a large sample container to produce a composite sample.

Whether the samples are collected manually or automatically, generally, they are ultimately analyzed in a laboratory.  They can be analyzed for biological, chemical, or physical parameters.  In Florida, the laboratory should or must be accredited by the National Environmental Laboratory Accreditation Program, NELAP (www.nelac-institute.org) and be certified by the Florida Department of Health (www.floridahealth.gov).  The data will not be accepted by regulatory agencies unless it is generated from one of these laboratories.

Why would you want to test the groundwater?  There are lots of reasons.  One is that you want to be proactive because you truly care or for public relations.  For example, you may want to produce groundwater quality data that show your facility is not polluting the groundwater below or adjacent to your facility.  Another reason may be for a groundwater remediation project, or to meet monitoring requirements under an existing Remedial Action Plan.  Additionally, you may have had a spill or discharge and you are being required or you are volunteering to test the groundwater quality.  In that case, you may need to determine if you have impacted the groundwater or if you have cleaned it up.  Finally, you may be planning to introduce a new operation and need to establish current groundwater quality conditions so that the operation’s impact can be projected.  After the operation is up and running, more testing can be done to determine if your projections were accurate.

If you do end up testing the groundwater, you will want to make sure that it is done properly and that the data are valid and court defensible.  Otherwise, you may end up with credibility problems.  Adverse publicity and scrutiny from the media and environmental watchdog groups is not worth it.  Even if you truly have no impact on the quality of the groundwater, it may be perceived that you do because of faulty data.

This is where Environmental Safety Consultants (www.escflorida.com) can help.  We have the credentials and experience to properly complete your groundwater environmental monitoring.  We are a Florida-licensed Engineering business with environmental scientists, a Professional Engineer (P.E.), and years of experience testing groundwater quality.  We are just a telephone call (800-226-1735) or an e-mail away ([email protected]).  Contact us today!

 

Soil Environmental Monitoring

One type of environmental monitoring is soil testing.  This sounds simple enough, but exactly what is soil testing?  Well, let’s break apart the term.Soil Environmental Monitoring

First, soil is the upper part of the earth’s crust in which plants can sometimes grow. It may be sandy, loamy, clayey, rocky, shelly, or peat-like.  Sometimes, it is referred to as dirt.  It is what we walk on when we go outside where there is no pavement, decking, pavers, concrete, etcetera.

Second, testing takes many forms.  It can be done with the unaided eye, electronic meters after mixing with water, organic vapor analyzers, or laboratory analysis.  Testing done on the soil samples in the field is called in situ testing.

Samples can be collected manually or with powered equipment.  Manually collected samples can be collected with spoons, augers, or dredges which are then transferred  into bottles in the field for in situ testing or into laboratory sample bottles for analysis at the laboratory.

Powered equipment typically includes split spoon samplers or direct push rigs which collect the soil samples from desired depths.  The soil is then transferred into the field bottles or laboratory sample bottles.  The samples are then either analyzed in the field or at the laboratory.

Whether the samples are collected manually or with powered equipment, generally, they are ultimately analyzed in a laboratory.  They can be analyzed for biological, chemical, or physical parameters.  In Florida, the laboratory should or must be accredited by the National Environmental Laboratory Accreditation Program, NELAP (www.nelac-institute.org) and be certified by the Florida Department of Health (www.floridahealth.gov).  The data will not be accepted by regulatory agencies unless it is generated from one of these laboratories.

Why would you want to test the soil?  There are lots of reasons.  One is that you want to be proactive because you truly care or for public relations.  For example, you may want to produce soil data that show your facility is not polluting the soil below or adjacent to your facility.  This could be related to the use or storage and handling of solvents, gasoline, diesel fuel, oil, pesticides, heavy metals, dry cleaning fluids, or many other chemicals.  Another reason may be for a soil remediation project, or to meet monitoring requirements under an existing Remedial Action Plan.  Additionally, you may have had a spill, discharge, or leak and you are being required or you are volunteering to test the soil for contamination.  In that case, you may need to determine if you have impacted the soil or if you have cleaned it up.  Finally, you may be planning to introduce a new operation and need to establish current soil conditions so that the operation’s impact can be projected.  After the operation is up and running, more testing can be done to determine if your projections were accurate.

If you do end up testing the soil, you will want to make sure that it is done properly and that the data are valid and court defensible.  Otherwise, you may end up with credibility problems.  Adverse publicity or scrutiny from the media and environmental watchdog groups is not worth it.  Even if you truly have no impact on the quality of the soil, it may be perceived that you do because of faulty data.
