Arsenic's carcinogenic role was noted over 100 years ago and has been studied ever since.

Arsenic is found in the environment in rocks, soil, water, air and in biota. Natural concentrations of arsenic in soil typically range from 0.1 to 40 mg/kg. The U.S. Geological Survey (USGS) estimates that at least 6% of all community water supplies will not comply with the new federal drinking water MCL and it will cost almost $200 million per year to do so. Layne engineers can determine which practical, cost-effective technologies are best suited to your water quality challenges.

The LayneOx Co-precipitation BAT Process removes both species of arsenic in the presence of iron, which may be concurrently present in groundwater or as an added constituent in the form of ferric chloride.

LayneRT has been developed as a significant improvement on the efficiency and longevity of adsorptive arsenic media, thus lowering the operating cost associated with removing arsenic (arsenate and arsenite) from water. Its ideal blend of selectivity and durability means that LayneRT can reliably and efficiently reduce arsenic to safe consumption levels.
