Lab Services Information

The American Bottoms Laboratory

The Illinois Environmental Protection Agency (IEPA) has granted the American Bottoms Laboratory a certification to perform environmental testing through the nationally recognized TNI (The NELAC Institute) organization.

The certification includes a rigorous Quality Assurance/Quality Control (QA/QC) system, proficiency testing of each certified analysis, and audits every two years from the IEPA.  The laboratory has been an accredited since 2002.

The laboratory has business hours of 7:30 am - 4:00 pm, Monday through Friday.  Our turnaround time is typically 10 business days, depending on the analysis.  Quicker turnaround may be performed, if requested, for a fee.  If you have sampling questions regarding sample containers, preservatives, or type of sample, please contact us

New customers include companies that haul wastewater, new local industries, other wastewater plants, or those in the region who desire a method compliant analysis from a TNI accredited laboratory.

For hauled wastewater customers, the American Bottoms Operations department will retrieve and transport the samples from the wastewater delivery. The laboratory will analyze what is requested based upon the Hauler's agreement.  For external sample locations, the laboratory accepts deliveries during the work week.

The testing normally performed in the laboratory provides data for 1) Compliance, 2) Pretreatment, 3) Operations,             4) Hauled Wastewater, or 5) billing purposes.  We also perform many tests as part of special studies that are non-routine.  If we do not perform the testing in-house, we subcontract to another TNI accredited laboratory that can perform the requested tests.

The analyses we perform, their approved method, and the costs are found on the Analyses page.  The types of samples, or matrices, that we analyze include wastewater, groundwater, and solid waste material.  For clarity, the tests are organized into the following types on the Analyses page:

1)     Conventional Wastewater Analyses

Conventional wastewater analyses include:

  • Total suspended solids and volatile suspended solids
  • Total dissolved solids
  • Total solids and volatile solids
  • pH
  • Biochemical oxygen demand (BOD)
  • Ammonia-Nitrogen
  • Total Kjeldahl Nitrogen (TKN)
  • Anions chloride, fluoride, sulfate, ortho-phosphate, nitrite, nitrate, and sulfate
  • Oil and Grease
  • Total phosphorus
  • Alkalinity
  • Total residual chlorine

These tests are typically needed for either compliance and/or operational monitoring.

2)     Metals and Organic Analyses

The metals parameters include testing for the following:

  • Antimony  
  • Arsenic  
  • Barium  
  • Beryllium  
  • Cadmium  
  • Calcium
  • Chromium  
  • Cobalt  
  • Copper  
  • Iron   
  • Lead     
  • Magnesium
  • Manganese
  • Nickel
  • Potassium 
  • Selenium
  • Silver
  • Sodium
  • Thallium
  • Tin
  • Zinc

The analysis of metals provides useful information for many aspects of the company including: insight into the removal efficiency of the treatment plant, for billing needs, and also compliance and pretreatment.  The testing for organic chemicals is primarily driven by pretreatment and compliance, but also for operational data.  Each organic analysis, which includes volatile organic and semi-volatile organic compounds, includes a lengthy list of calibrated compounds.

3)     Toxic Characteristic Leaching Procedure (TCLP) Analyses

The TCLP procedure is used to extract the parameters found in a solid matrix sample to a liquid or extract.  The results from the analysis on the extract are compared to the EPA regulatory level to determine if the sample is hazardous or non-hazardous.

Laboratory Mission

Most important for the laboratory is to follow the Mission of American Bottoms as we perform the needed tasks to accomplish our goals: we must be safe, which means proper personal protective equipment (safety glasses, protective gloves, lab coats, etc), thorough training, and working at a pace which allows for secure handling of potentially hazardous chemicals and containers; we must provide EPA approved, method compliant data to the customers for confidence in the final results and to meet EPA requirements.  By meeting the EPA sampling and analysis requirements, the data may be used for our permit and those permits that we provide data for; finally, we strive to be cost effective by continually pushing each other to think of smarter ways to purchase supplies, perform analyses, and utilize professional contractors.
