Q. What kind of environmental projects have you worked on?

A. American has experience on many different projects, having conducted testing for cities, boroughs, municipalities, industrial clients, on a weekly, monthly, and quarterly compliance monitoring basis. Supported programs include SDWA, NPDES, CWA, etc. American also performs sampling and testing for landfills in support of the various environmental monitoring programs designed specifically for each individual landfill or waste monitoring facility. For environmental consultants, American performs testing for programs including remediation, compliance monitoring, engineering support, RCRA, SARA, UST, USACE, etc.

Q. For what purposes do American clients use environmental testing and analytics?

A. Data derived from American Analytical Laboratories is typically used in the following applications:

  • Environmental baseline and compliance monitoring programs
  • Site assessment and remediation
  • Sediment assessment for dredging
  • Drinking, catchment, recycled and desalination water monitoring
  • Occupational / industrial hygiene
  • Waste characterization
  • Other disciplines requiring a sophisticated analytical approach

Q: Which compounds are on the Hazardous Characteristics List?

A: Hazardous Characteristics are the parameters identified by the USEPA that define a hazardous waste. They are Toxicity, Ignitability and Corrosivity. While a fourth characteristic, reactivity, was recently withdrawn by the USEPA, several regulatory agencies continue to request the parameter. A positive test for any one characteristic defines the waste as hazardous.

Q: What constitutes the Toxicity test?

A: Toxicity is determined with a simulated leach of the waste. The leachate is analyzed for a regulated list of compounds consisting of Volatile Organics, Pesticides, Herbicides, Semi- Volatile Organics and Metals. The Toxicity of Characteristics Leaching Procedure (TCLP) is used for Pesticides, Herbicides, Semi-Volatile Organics and Metals, while the Zero Headspace Extraction (ZHE) is used for Volatile Organics.

Q: What is the difference between Limit of Quantitation (LOQ) and Limit of Detection (LOD)?

A: The LOQ is the lowest concentration standard in the calibration range of each compound analyzed. This value is also the low limit for unqualified quantitative data. The LOD is determined via experimentation and verified through additional testing. This value represents the lowest concentration of each compound that can be qualitatively identified by the method in use.

Q: Does American supply field-sampling services?

A: Yes. American’s sampling team features OSHA-trained professionals, including the 40-hour OSHA HAZWOPER and 8-hour HAZWOPER Annual Refresher courses.
