• Arsenic is a naturally occurring element found in the earth’s crust. Erosion, weathering, and industrial runoff can deposit arsenic into our aquifers.
  • EPA established a Maximum Contamination Level for Arsenic of 10 micrograms per liter (µg/L) or parts per billion (ppb) in 2001. In amounts over 65mg arsenic is considered to be toxic to the human body and in smaller amounts known to impact cancer growth and diabetes development.
  • Arsenate as an insoluble precipitate, is charged allowing its adsorption to iron compounds. The exposure to an oxidant allows arsenate to “co-precipitate” with iron and physically filtered out.
