Groundwater project demonstrates successful arsenic remediation
Arsenic and uranium in drinking water supplies
LayneRT is a hydrous iron oxide impregnated resin that efficiently binds arsenic and never needs backwashing. It is engineered in a single-column design to treat a full cold-water flow so no special low-flow faucet is needed. The POU system provides simple installation and comfortably fits under most sinks. Because system performance is tied to site-specific water chemistry, SolmeteXWater has integrated a comprehensive sampling program into the npXtra system to ensure continued performance. Chemists regularly analyze your customer’s water quality by sending them pre-paid sample kits.
It has been estimated in a national arsenic occurrence survey of drinking water supplies that as many as 35 to 40% of U.S. public water systems have arsenic above the maximum contaminant level (MCL) of 10 parts per billion (ppb), and have co-occurrence of iron above the secondary MCL of 0.3 mg/L. This presents an interesting challenge for small systems, which may or may not have any treatment in place for either iron or arsenic to meet their respective MCLs.
