Fully accredited laboratory network supporting a wide range of organic, inorganic, and biological assays. Regulatory analytical support includes water quality guidance for such initiatives as NPDES discharge testing, county municipality requirements, industrial pretreatment monitoring, and storm water management plans.

Our scientists and technicians support thousands of facilities across the US with our waste water treatment monitoring and storm water testing lab. With a detailed understanding of NPDES and Industrial General Permit requirements, large sample throughput capacity, and the ability to perform rush analysis, Enthalpy is well-suited to support wastewater and storm water projects of any magnitude.
