Currently, the EPA is reviewing its MCL recommendations for arsenic since technological advancements such as the SafeGuard™ H2O now make it possible to treat to levels of 5 ppb and lower economically. SafeGuard™ H2O is proven to eliminate arsenic and drastically reduce the cost of removing this toxic contaminant from drinking water supplies. The SafeGuard H2O arsenic treatment system generates a ferric reagent in-situ through a simple, effective and sustainable process.
