CFR 40 Part 141 Determination of Arsenic Barium Chromium Selenium in Drinking Water
The United States Environmental Protection Agency (EPA) established Clean Water Act (CWA) regulations under CFR 40 Part 141, which governs the safety and quality of drinking water. Compliance with these standards is crucial for all entities involved in the production, distribution, or supply chain of potable water.
The specific parameters outlined in CW A Rule 141 mandate the presence of certain elements that can be harmful to human health if present at unsafe levels. Among these are arsenic, barium, chromium, and selenium. Each element has its own permissible limits based on long-term exposure risks.
The determination of these elements in drinking water is a critical aspect of ensuring public safety. Arsenic, for instance, can cause cancer and other severe health effects even at low concentrations. Barium can interfere with the body's ability to absorb calcium, which may lead to cardiovascular diseases over time. Chromium (VI) has been linked to various cancers while selenium, though essential in small amounts, can be toxic at higher levels.
CFR 40 Part 141 specifies that facilities must monitor and control the concentration of these contaminants in drinking water systems. This involves periodic testing to ensure compliance with EPA standards. The determination of arsenic, barium, chromium, and selenium is a multi-step process involving sample collection, preparation, analysis using advanced instrumentation such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and reporting the results.
