Organochlorine pesticides and PCBs measurement context
EPA Method 608: the sample is extracted with methylene chloride and the extract is analyzed by gas chromatography with an electron capture detector. The pesticide scan covers organochlorine pesticides such as aldrin, dieldrin, endrin, heptachlor, the BHC isomers (including lindane), chlordane, toxaphene and DDT, DDD and DDE; the PCB scan reports the Aroclors 1016, 1221, 1232, 1242, 1248, 1254 and 1260. The two scans can be run together. Solid samples are tested for the pesticides by EPA SW-846 Method 8081.
Confirm matrix and regulatory context
Environmental water, wastewater and companion solids need explicit applicability review. SW-846 and Clean Water Act methods are not automatically interchangeable for permit reporting.
Include the complete project requirement
Provide the matrix, target analytes, required method, fraction, units and reporting limits. Include the permit or monitoring instructions where results will support a regulatory submission. Naming this method does not establish blanket compliance eligibility.
Resolve collection before sampling
Use the bottle, preservation and delivery instructions assigned to the agreed scope. Identify each location and collection time, and document any deviation. The final analytical plan must fit the submitted material and its intended use.
