Superfund Research Program
Chemical Transport, Transformation and Human Exposure on the Aberjona
Project Leader: Harold F. Hemond
Grant Number: P42ES004675
Funding Period: 1995 - 2000
Project Summary (1995-2000)The objective of this project is to identify the environmental chemicals that present human health hazards, to identify the environmental pathways of these chemicals, and to quantify past, present, and future human exposure to these chemicals. Research focuses on: a) processes leading to human exposure to toxic chemicals via drinking water pumped from municipal wells G and H in Woburn between 1964 and 1979; b) quantification of chronic and episodic release of toxic metals, especially arsenic, chromium, and mercury, from sediments into the heavily-utilized surface waters of the watershed; and c) quantification of primary environmental fate and human exposure processes, including biodegradation and movement of soil vapor, of anthropogenic organic chemicals on the watershed. Contribution to public education, and outreach to the community of the Aberjona watershed also continue to be important goals of this work.
