The firm has unparalleled technical and legal expertise on the review and development of water quality standards. The purpose of such analyses is to ensure that the state is applying the most current scientific information in the derivation of applicable standards. Review of background and technical support documents associated with state WQS proposals and triennial review updates are performed. Analyses of over one dozen state programs have been completed leading to major program revisions to ensure the imposition of necessary and appropriate effluent limitations.
Our detailed assessments identify key assumptions and data deficiencies associated with such actions, in addition to determining the scientific information needed to resolve key uncertainties. Recent water quality standard reviews include proper application of human health objectives for arsenic and nitrate, E. Coli body contact recreational standards, and aquatic life standards for copper, atrazine, and nutrients.
