RCRA 8 metals measurement context
The eight metals named in the federal hazardous waste rules: arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver, measured in a liquid sample by the ICP and cold vapor methods above. Reported as mg/L.
Define the element list and fraction
Name the elements and state total, total recoverable or dissolved preparation as required. Filtration and preservation belong in the collection plan, and reporting limits must support the project criteria.
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.
