What is Arsenic?
Arsenic is a naturally occurring metalloid found in bedrock that dissolves into groundwater, particularly in areas with volcanic or sedimentary geology. Industrial sources include mining, pesticide residues, and wood preservatives. The EPA maximum contaminant level is 10 parts per billion. Long-term exposure to arsenic in drinking water increases the risk of bladder, lung, and skin cancers, as well as cardiovascular disease.
Who is most at risk in Suffield?
Arsenic matters most for infants, pregnancy — a developmental toxin linked to harm in pregnancy and early childhood. The safe level for these groups is stricter than for a healthy adult.
How to remove Arsenic from your water
Install a point-of-use reverse osmosis system certified to NSF/ANSI Standard 58 for arsenic reduction, which effectively removes both arsenic III and arsenic V forms when paired with an oxidation prefilter.
Use an adsorptive media filter containing iron-based media such as granular ferric hydroxide, which has high affinity for arsenic and is effective for whole-house treatment.
For well water, add an oxidation step (chlorination or aeration) before filtration to convert arsenic III to arsenic V, which is more readily removed by most filter technologies.
Test your water to determine the specific arsenic species present, as treatment effectiveness varies between arsenic III (arsenite) and arsenic V (arsenate).
