According to the EPA long-term exposure to arsenic in drinking water is linked to cancer of the bladder lungs skin kidneys nasal passages liver and prostate. These are based upon non-cancer health effects. Be that as it may the EPA suggests that open water systems maintain pH levels in the range of 65 and 85 a great guide for individual well water owners.

The data surrounding this association is difficult to interpret due to the large variation in study designs and the highly variable quality of these studies. Noncancerous effects of ingesting arsenic include cardiovascular pulmonary immunological neurological and. Affecting children --both in utero and born-- as well as adults.
