Cost-effective SafeGuard™ H2O Arsenic Removal Technology
Cost-effective SafeGuard™ H2O Arsenic Removal Technology Paves the Way for More Stringent Federal Arsenic Standards
n 2001, the U.S. Environmental Protection Agency (EPA) lowered the federal arsenic (As) standard from 50 parts per billion (ppb) to 10 ppb, where it remains today apart for New Hampshire and New Jersey that have implemented a more stringent maximum contaminant level (MCL) of 5 ppb at the state level. EPA’s decision to hold the MCL level at 10 ppb for more than 20 years stems from the fact that the best available treatment technologies (BATs) typically have had very high investment and operating costs, making it prohibitive for many water utilities to cost-effectively treat down to levels lower than 10 ppb. Currently, the EPA is reviewing its MCL recommendations for As since technological advancements such as the SafeGuard™ H2O now make it possible to economically treat to levels of 5 ppb and lower.
