Carbon Tetrachloride in Drinking Water: Health Risks, Sources, and How to Remove It
Carbon tetrachloride is an organic contaminant regulated in drinking water. The US Environmental Protection Agency has set a Maximum Contaminant Level (MCL) of 5 μg/L for this compound to safeguard water supplies. It is classified under organic chemicals and is monitored to prevent potential health issues.
Health Effects
Exposure to carbon tetrachloride in drinking water can lead to health issues, including liver problems. Additionally, consumption of water contaminated with this organic chemical is associated with an increased cancer risk. Keeping levels below the regulatory limit helps mitigate these chronic health concerns.
How Carbon Tetrachloride Gets Into Tap Water
This contaminant enters water supplies primarily from industrial sources. Releases from chemical plants and other industrial activities can introduce carbon tetrachloride into groundwater or surface waters. Proper monitoring is essential near areas with active or historic industrial operations.
How to Remove Carbon Tetrachloride From Your Water
Carbon tetrachloride can be removed from drinking water using specific treatment methods. Granular activated carbon systems are widely utilized to filter this compound. Additionally, packed tower aeration is an effective method for removing this organic contaminant.
Should You Test Your Water?
To verify the levels of carbon tetrachloride in your drinking water, you can review your local utility's annual consumer confidence report or check the WaterQ database. If you use a private well near industrial areas, getting your water tested by a certified laboratory is recommended. You can also look up your local water system on WaterQ or check the Carbon Tetrachloride data page for reported levels in your area.
