The BoRit Asbestos Superfund site is a 32-acre (13 ha) waste dump and reservoir in Ambler, Upper Dublin Township and Whitpain Township, Pennsylvania that was contaminated with 1.5 million cubic yards (1.1×10^6 m3) of asbestos containing material due to the waste disposal practices of the Keasbey and Mattison (K&M) Company and Turner and Newall from 1897 to 1962.

The site is currently being monitored on a quarterly basis and after significant weather events to ensure the integrity of the cap and stabilized stream banks.

The location along the North Pennsylvania Railroad line was ideal for operations since raw asbestos could be easily brought in from Quebec and finished products sent out to markets.

Nicolet pumped asbestos-containing water into settling ponds which created wet asbestos piles that gradually dried.

The site was fenced in by 1986 but the EPA determined that the asbestos pile fell below the threshold level of risk to place it on the National Priorities List.

The site was monitored by the PADEP and continued to be used during the 1980s and 1990s as a trash transfer and storage location as well as for local fire department training.

The State denied the application and ordered the companies to stop dumping asbestos and cover the waste piles.

[11] In 1987, Nicolet Industries filed for bankruptcy and ceased production of asbestos-containing materials after being named in 50,000 cases of bodily injury caused by asbestos.

[14] In 2005, housing developer Kane Core submitted plans for the construction of a 17-story high rise on the asbestos waste dump parcel.

[12] In 2014, the University of Pennsylvania received a $10 million grant from the National Institute of Environmental Health Sciences to study the impact of asbestos on the community of Ambler.

[4] The EPA issued a Record of Decision (ROD) in July 2017 which documented the remediation of the site which included covering the asbestos waste pile with a geotextile material and two feet of clean fill.
