For water quality monitoring, we offer multiple techniques for the analysis of drinking water, surface water, groundwater, and wastewater to comply with legislation and regulations. The Safe Drinking Water Act (SDWA) and the Clean Water Act (CWA) are the two important environmental laws governing water regulations in the United States. These laws require the U.S. Environmental Protection Agency (EPA) to set regulatory standards and approve analytical methods for testing drinking water and wastewater discharged to surface water.
