- In May 2002, the U.S. Environmental Protection Agency (EPA) received $1.25 million from the National Gypsum bankruptcy trust to fund the Remedial Investigation/Feasibility Study (RI/FS) to determine the extent of the contamination in the ground water and to determine whether further remediation is necessary beyond the initial cleanup performed by Pennsylvania Department of Environmental Protection (PADEP) and EPA.
- In February 2007, the RI Report was completed.
- A Proposed Plan for Operable Unit 1 (source control) was issued on August 2, 2012. A 30-day public comment period was open August through August 31, 2012.
- EPA issued a Record of Decison (ROD) (PDF) (118 pp, 24.2 MB) in September 2013 which documents the final cleanup for Operable Unit 1 (Source Control).
- The Salford Quarry site is an early 1900’s-era shale quarry located on approximately three acres in Lower Salford Township, Montgomery County, Pennsylvania.
- Approximately 54,000 people draw drinking water from public and private wells within three miles of the site.
- In the 1950s, the Ludwig and Son waste disposal business used the quarry as a dumping point for industrial, commercial, and residential waste. Fly ash cinders from a coal-fired power plant were also disposed at the site.
- The site was acquired by the American Encaustic Tiling Company [later known as American Olean Tile Company, Incorporated (AOT) in April 1963.
- As early as 1963 to 1980, AOT used the unlined quarry for the disposal of glaze wash-up sludge, settling pond sediment, and fired and unfired scrap tiles from its Lansdale, Pennsylvania plant
- In 1982, the site was closed with the Pennsylvania Department of Environmental Resources approval after AOT discovered two 10,000-gallon tanks containing boron and fuel oil buried on the site.
- In 1990, the EPA added the site to the National Priorities List of most hazardous waste sites in the country, making the site eligible for federal cleanup. A June 1992 decision by the United States Court of Appeals removed the Salford Quarry site from the NPL. It was added again in 2009.
NPL Listing History
|Status: Final||Added: 1990|
- In 1981, AOT discovered two 10,000-gallon tanks containing boron and fuel oil buried on the site.
- In 1982, after the company pumped out the remaining oil, the site was closed. The closure plan involved installing a soil cover and sampling the monitoring wells on site.
- In 1992, after boron contamination was discovered to have reached homes as far away as one-half mile from the site, EPA’s emergency personnel became involved with a waterline installation. During the period when EPA was constructing this waterline, bottled water was supplied to affected residents by the Potentially Responsible Parties (PRPs). This waterline extension extended beyond immediately affected residents to homes where boron contamination may eventually reach, enabling all immediate threats to human health to be eliminated while EPA evaluated whether additional studies of cleanup activities were necessary. As a result of this action by EPA, 113 homes were connected to public water.
- Under an agreement with EPA, the PRP conducted a study of groundwater contamination to evaluate the extent of the contamination and identify the best cleanup strategy. This study was nearly complete when a combination of the PRP's bankruptcy, the site's removal from the NPL, and the discovery of home well contamination terminated further investigation.
- In May 2002, the EPA began its own Remedial Investigation to investigate the contamination associated with the site. Field sampling was conducted in 2002 and 2004 to assess the current extent of contamination. In February 2007, a final Remedial Investigation Report was completed. A Feasibility Study, which evaluates cleanup options for the Site, was completed in June 2007.
- EPA divided the Site into two Operable Units (OUs) in order to address the source first. OU1 addresses contamination in the quarry waste, surrounding soil and sediment. OU2 will address contamination in groundwater, surface water, and vapor intrusion, if necessary. A Record of Decision (ROD), documents the selection of the final cleanup for OU1 and was issued in September 2013.
- On and off-site groundwater has been contaminated with volatile organic compounds (such as trichloroethylene or TCE, 1-2-dichloroethene and vinyl chloride, which are chemical components of solvents and degreasers), inorganic metals (such as lead), and a large amount of boron, most likely originating from the production of floor tiles.
- Groundwater in contact with quarry waste, soil and sediment continues to leach chemicals from the Site. Groundwater flows in a southwest direction.
- Although immediate human health risks have been eliminated with the waterline installation, animals and the environment may still be at risk through ingestion or direct contact with contaminated ground water that seeps into surface water.
- Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
