Havertown Superfund
Havertown Superfund is a 13-acre polluted groundwater site in Havertown, Pennsylvania contaminated by the dumping of industrial waste by National Wood Preservers from 1947 to 1991. The state first became aware of the pollution in 1962 and initiated legal action against the owners in 1973 to force them to cleanup the site. The Environmental Protection Agency (EPA) ranked the site the eighth worst cleanup project in the United States. The site was added to the National Priorities List in 1983 and designated as a Superfund cleanup site in the early 1990s. Remediation and monitoring efforts are ongoing and the EPA transferred control of the site to the Pennsylvania Department of Environmental Protection in 2013. The site was deemed to be "short-term protective of human health and the environment" in the sixth five-year report conducted by the EPA in 2020.

Wood Preservation
Wood easily degrades without sufficient preservation. Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as "timber treatment", "lumber treatment" or "pressure treatment") that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungi. History As proposed by Richardson, treatment of wood has been practiced for almost as long as the use of wood itself. There are records of wood preservation reaching back to ancient Greece during Alexander the Great's rule, where bridge wood was soaked in olive oil. The Romans protected their ship hulls by brushing the wood with tar. During the Industrial Revolution, wood preservation became a cornerstone of the wood processing industry. Inventors and scientists such as Bethell, Boucherie, Burnett and Kyan made historic developments in wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naylors Run
Naylors Run is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 tributary of Cobbs Creek in Haverford and Upper Darby Township, Pennsylvania, United States. In 1975, a small dam was built near Naylors Run Park to help control flooding. Naylors Run flows underground in Upper Darby from Sherbrook Boulevard to Walnut Park Drive, where it joins Cobbs Creek. Thousands of feet of Naylors Run were channeled into underground culverts to facilitate commercial and residential development in the filled land above the pipes. Naylors Run joins Cobbs Creek near 63rd st and Cedar Lane. Naylors Run would normally be an intermittent stream, but it has become a perennially flowing stream because of the treated water discharged from the Havertown PCP Superfund water treatment facility.
