Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.
4
If o-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 mg/l.

EPA Listed Hazardous Waste
Learn more about hazardous waste and the regulations that govern it:
-
Generators: Hazardous
waste generators are divided into categories based on the amount of
waste they produce each month. Different regulations
apply to each
generator category.
-
Transporters: Hazardous
waste transporters move waste from one site to another by highway, rail,
water, or air. Federal and, in some cases, State regulations govern
hazardous waste transportation, including theManifest System
-
Waste Minimization: EPA,
States, and industries are working to reduce the amount, toxicity, and
persistence of wastes that are generated.
-
Corrective Action: RCRA
compels those responsible for releasing hazardous pollutants into the
soil, water, or air to clean up those releases.
-
Test Methods: EPA
has a variety of analytical chemistry and characteristic testing
methodologies, environmental sampling and monitoring, and quality
assurance in place to support RCRA.
-
International Waste: EPA
provides information and guidance on regulations, agreements,
initiatives, and other developments in waste policy and law, both in the
United States and abroad.
