EPA 641 Selenium Compliance Test in Drinking Water
Ensuring compliance with the Environmental Protection Agency’s (EPA) Clean Water Act is a critical responsibility for water utilities and municipalities. The EPA has established stringent limits on selenium concentrations to protect public health and aquatic ecosystems, particularly in areas where selenium can accumulate and cause harm.
The EPA 641 Selenium Compliance Test requires the analysis of drinking water to ensure that it meets the specified concentration limits. This test is crucial for utilities that must demonstrate compliance with the Safe Drinking Water Act (SDWA) and the Clean Water Act (CWA), which mandate strict controls on contaminants, including selenium.
The EPA’s Selenium in Drinking Water regulation sets a maximum contaminant level goal (MCLG) of 0.05 mg/L and an MCL of 0.05 mg/L for selenium in drinking water. This means that utilities must ensure their treated water does not exceed this concentration to avoid potential health risks.
The EPA 641 Selenium Compliance Test involves a series of complex steps, from sample collection and preservation to analysis using advanced instrumentation such as inductively coupled plasma mass spectrometry (ICP-MS). The testing process is designed to provide accurate, reliable results that meet the stringent standards set by the EPA.
The following sections will delve into the technical aspects, applied standards, benefits of our services, and the international recognition of this test. These details are essential for quality managers, compliance officers, R&D engineers, and procurement professionals who need to ensure their water systems comply with regulatory requirements.
