Description:
(Note: This entry is no longer valid; the paper was rewritten and submitted to a different journal.) This paper highlights some methods that can be used at a local scale to assess whether waste disposal activities are responsible for enhanced arsenic mobility through redox-controlled processes. A case study is presented from the Mottolo waste site, a USEPA Superfund site in Raymond, NH. The Mottolo site is underlain by shallow bedrock (less than 10 meters deep) of the Berwick Formation: a metasedimentary rock derived from marine sediments, which has been associated with regionally (county scale) high concentrations of arsenic in groundwater.
