The pesticides DDT and Dieldrin were widely used in these agricultural areas. Although DDT and Dieldrin have not been used since 1970, high levels of DDT and Dieldrin still persist in the shallow soils within the former orchard. It is suspected that these pesticides may leach to the water table. Thus contaminated groundwater may represent a pathway to exposure to humans through the Park's water supply wells, and to the aquatic ecosystem via groundwater discharge to the marsh"--Abstract.
