The goal of this project was to determine remedial strategies for the former landfill in Holden, MA to reduce mobility and toxicity of metals. To meet this goal, 16 groundwater and 5 surface water samples were collected at the landfill site. Physical and chemical water quality tests showed reducing conditions (favorable for arsenic dissolution) at 4 of the 16 groundwater wells. Samples were analyzed for arsenic, manganese, lead, iron, and cadmium. Dissolved arsenic was above drinking water standards at one well, but below groundwater standards in all wells. Most of the arsenic was in the particulate form. Remedial strategies to reduce mobility of arsenic were evaluated based on criteria such as cost and long-term effectiveness. The no action/monitor strategy is recommended for this site.
