So little is known about 4-MCHM that regulators didn’t even know it’s boiling point. Now scientists are scrambling to find out how the chemical reacts with the chlorine in the municipal water system, and whether the chemical has leached into water heaters and water pipes in people’s homes. Authorities recommend that all pipes that have come in contact with the pollutant be flushed, including water heaters and outdoor faucets.
However, West Virginia American Water, the company that owns the water treatment facility contaminated by the coal chemical, is only offering a 10 dollar credit (1000 gallons) to consumers. The cost of flushing homes will therefore fall on already struggling West Virginians.
