PERFORMANCE ASSESSMENTS OF A NOVEL WELL DESIGN FOR REDUCING EXPOSURE TO BEDROCK-DERIVED ARSENIC
Winston, R.B. and J.D. Ayotte.
Groundwater 56(5):762-769(2018)

Arsenic in groundwater is a serious problem in New England, particularly for domestic well owners drawing water from bedrock aquifers. The overlying glacial aquifer generally has waters with low As concentrations but is less used because of frequent loss of well water during dry periods and the vulnerability to surface-sourced bacterial contamination. An alternative, novel design for shallow wells in glacial aquifers is intended to draw water primarily from unconsolidated glacial deposits, while being resistant to drought conditions and surface contamination. Its use could greatly reduce exposure to As through drinking water from domestic wells. See the well design patent at https://patents.google.com/patent/US9689235B1/en.
