DBCP and ethylene dibromide (EDB) measurement context
1,2-Dibromo-3-chloropropane (DBCP) is a former soil fumigant, and EPA lists runoff and leaching from its use as the source in drinking water; EPA lists discharge from petroleum refineries as the source of ethylene dibromide. Both are regulated at very low levels: the EPA maximum contaminant levels are 0.0002 mg/L for DBCP and 0.00005 mg/L for EDB. Concentrations this low are usually expressed in µg/L.
Provide the compound list
A class name does not establish every target included. Specify the compounds, applicable drinking-water program and reporting limits; use the prescribed bottle and handling plan for the scope.
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.
