ERIN BROCKOVICH CHEMICAL TAINTING CASS COUNTY WATER?
A quick post for the locals. The cancer-causing form of chromium (chromium-6, also known as hexavalent chromium — the chemical made famous in the 2000 movie “Erin Brockovich”) has been found in all four of the water treatment systems that were tested in Cass County. 31 out of 31 of the water samples tested positive with an average chromium-6 level of 2.13 ppb. That is over 100x higher than the negligible risk standard of 0.02 ppb, and the third highest level out of all tested Missouri counties.
As a dissolved solid, standard carbon filters (e.g. Brita, PUR, etc.) are inadequate for removing chromium-6. Reverse osmosis (RO) is the best and most accessible water purification technology for removing this and other dissolved solids. A good RO unit will remove 99%+ of the chromium-6 in the water. Having a good water purification system is a good idea, anyway, even apart from the chromium-6 issue.
