Water and Wastewater Chemistry
AC&T provides chemical analyses for compliance with State and Federal
drinking water standards, aquifer protection permits, wastewater AZPDES/NPDES permits, and surface water
designated use standards. Constituents analyzed include forms of chlorine, nitrogen species, phosphorus,
solids, metals, biochemical and chemical oxygen demand, anions, and total organic carbon. Specialized
soil testing is available for contaminant identification, toxicity assessments, bioremediation support
and general agronomic studies. Chemical testing and sampling for AZPDES/NPDES industrial and municipal
storm water runoff permits are available. AC&T also provides process and surface water contaminant identification.
