Acrylamide and epichlorohydrin measurement context
Both are monomers that can remain in water treatment chemicals: acrylamide in polyacrylamide coagulant aids, and epichlorohydrin as an impurity of some treatment chemicals. EPA regulates them by treatment technique rather than by a maximum contaminant level: each water system certifies to the state that the dose of the treatment chemical combined with its monomer level stays within set limits (acrylamide 0.05% dosed at 1 mg/L; epichlorohydrin 0.01% dosed at 20 mg/L). Contact us before sampling if you need either compound measured in water.
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.
