Hydrochemical characterization of groundwater in a wetland-upland transitional zone, Norwell, Eastern, Massachusetts
Abstract
Iron and Manganese contamination of ground water is the single most frequent obstacle in developing many potential aquifers as municipal and/or private drinking water supplies in Massachusetts. During an eighteen-month monitoring study of ground water in observation wells, in-situ hydrochemical data were obtained from two separate redox domains, side-by-side in one aquifer in response to a full-scale pumping test. Measurements taken (pH, depth, temperature, specific conductance, DO, ORP) within each domain prior to pumping support the presence of an oxidizing regime within the dry, upland domain, and a reducing regime within the wet, lowland domain. Measurements taken after the conclusion of the pump test show evidence of mixing between the two regimes, with a mild hydrochemical recovery within the upland after four months.
