Description:
The United States Environmental Protection Agency (EPA) recently reduced the drinking water standard for arsenic (As) in water from 0.05 to 0.010 milligrams/Liter (L) (10 micrograms/L). This reduction was prompted by new health effects research, which concluded that extended human exposure to this element can cause severe illnesses (including various types of cancers) at much lower levels than previously believed. The recent revision to the arsenic standard has required many new water treatment systems to apply treatment processes. Findings from this study will further enable EPA to provide subject matter expertise and guidance on best available technologies for the removal of arsenic from drinking water.
