MTBE (Methyl tert-Butyl Ether) in Drinking Water: Health Risks, Sources, and How to Remove It
MTBE (Methyl tert-Butyl Ether) is a chemical compound categorized as an organic contaminant. The EPA has established a Maximum Contaminant Level (MCL) of 20 μg/L for this substance in drinking water. Understanding its properties and regulatory limits helps ensure tap water safety.
Health Effects
Consuming water contaminated with MTBE can lead to adverse health outcomes, including nervous system effects. Additionally, there is a possible cancer risk associated with exposure. It is important to monitor water sources to mitigate these potential health risks.
How MTBE (Methyl tert-Butyl Ether) Gets Into Tap Water
MTBE typically enters drinking water supplies from gasoline-related sources. It has commonly been used as a fuel additive, which can lead to contamination of nearby water supplies. A primary pathway for this contaminant to reach groundwater is through leaking gasoline tanks.
How to Remove MTBE (Methyl tert-Butyl Ether) From Your Water
Several methods can be used to treat and reduce MTBE levels in drinking water. Granular activated carbon systems are commonly employed to filter this organic compound from water supplies. Alternatively, air stripping is an effective treatment method to remove the contaminant during the water purification process.
Should You Test Your Water?
If you are concerned about MTBE in your water, you can check your local consumer confidence report or search the WaterQ database. Private well owners may want to consider periodic testing, especially if they live near gasoline storage facilities. You can also look up your local water system on WaterQ or check the MTBE (Methyl tert-Butyl Ether) data page for reported levels in your area.
