Havertown Superfund
Havertown Superfund refers to the polluted groundwater site in Havertown, Pennsylvania. While its designation as a Superfund cleanup site did not occur until the early 1990s, the site's environmental hazards had been identified as early as 1973.
==History==
In 1947, Natural Wood Preservers established a wood treatment plant at the intersection of Eagle Road and West Hillcrest Avenue in Havertown, Pennsylvania. During its operation in the treatment of the wood, hazardous chemicals (including oil, dioxins, and pentachlorophenol) were created as waste products. Natural Wood Preservers disposed of these waste products, untreated, into an on-site well. These chemicals fed directly into Naylor's Run Creek and eventually into the Delaware River, for which the creek is a tributary.
This disposal of hazardous waste continued for a minimum of several decades during the company's ownership of the site, which ended in 1991. During the company's 44-year ownership, both local and federal government bodies attempted to force Natural Wood Preservers to stop their dumping and clean up the existing pollution.
