Compounds

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. A fourth characteristic, reactivity was withdrawn by the USEPA. However, 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.

Methods

Q: How do I know which method to use?

A: Federal Regulations for environmental compliance typically incorporate a group of analytical chemistry methods which are specific for that regulation. For example, if you are sampling under the Safe Drinking Water Act (SDWA), you should use 500-series methods for organics and 200-series methods for inorganics. Applications for the SDWA are drinking water systems, delivery point monitoring, receptor and private wells .

Reporting Limit (RL) and Method Detection Limit (MDL)

Back to Top »

Q: What is the difference between Reporting Limit (RL) and Method Detection Limit (MDL)?

A: The RL 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 MDL 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.

Certifications

Q: What states and federal programs is SGS Accutest certified in?

A: Visit the SGS Accutest State Certification and Accreditation page.

Samples and Sampling Services

Q: Does SGS Accutest analyze air samples?

A: SGS Accutest Laboratories routinely performs the analysis of whole air samples collected in Tedlar Bags or Summa Canisters to support the USEPA Air Toxics Program. The laboratory currently uses two procedures: TO-3/EPA 18, which is a gas chromatographic method employing, in tandem, photo ionization (PID) and flame ionization detectors (FID); and TO-14/ TO-15, which is a GC/MS method.

Q: Does SGS Accutest supply field-sampling services?

A: Yes, SGS Accutest offers field-sampling services.  Learn more about our field-sampling services.
