Asbestos in Pennsylvania

History of Asbestos Use in Ambler, Pennsylvania

Asbestos manufacturing started in Ambler, Pennsylvania, in 1896. That year, the Keasbey & Mattison Company opened the first asbestos textile plant and began manufacturing insulation. The company’s insulation used magnesium carbonate and asbestos.

Ambler offered easy access to natural resources and a nearby railroad. This combination helped Keasbey & Mattison grow quickly and attracted other companies to the town. As the asbestos industry grew, more workers and residents were put at risk of dangerous asbestos exposure.

Keasbey & Mattison Manufactured Asbestos Products for Decades

The Keasbey & Mattison asbestos factory operated under different owners for nearly 100 years. By 1962, CertainTeed Corporation and Nicolet Industries owned the facility. This facility manufactured many asbestos products, including:

So, the workers at these facilities may have been exposed to asbestos on the job.

From the 1930s to roughly 1974, companies also piled asbestos waste near the town. Residents called the area the White Mountains of Ambler. This area covered 25 acres of land. Estimates put the total amount of debris at more than 1.5 million cubic yards of asbestos waste.

The White Mountains, also known as the Ambler Asbestos Piles, may have exposed thousands of people to asbestos. Any exposure can lead to asbestos-related diseases like mesothelioma, lung cancer and asbestosis. Anyone who develops an illness after exposure to Ambler’s asbestos may have legal options.

Health Impacts of Asbestos in Ambler, Pennsylvania

Ambler’s asbestos contamination put thousands at risk of exposure. Workers and their family members developed mesothelioma and other asbestos-related diseases.

Asbestos dust covered homes and vehicles close to the White Mountains in Ambler. The town had playgrounds near the asbestos piles. And children used to play on the asbestos piles.

Keasbey & Mattison’s actions exposed workers to asbestos fibers. In some cases, their family members also experienced secondhand asbestos exposure. And people who used the company’s products risked exposure. As a result, many people later developed mesothelioma because of the widespread asbestos use and dumping in Ambler.

People in Ambler continue to face elevated cases of asbestos-related diseases. Mesothelioma has a long latency period, meaning it takes a long time for symptoms to start. It can take 10 – 50 years before people have mesothelioma symptoms.

Mesothelioma Incidence in Ambler, Pennsylvania

Studies show mesothelioma incidence is higher in Ambler than the statewide average. In a Pennsylvania Department of Health study, researchers analyzed mesothelioma cases in Ambler from 1992 to 2008. They found the rates of mesothelioma in Ambler were:

  • 2.7 times higher than average for men
  • 4.5 times higher than average for women

Overall, the researchers found the incidence of mesothelioma was 3.1 times higher than expected in Ambler. The researchers also stated mesothelioma rates for neighboring towns were not elevated.

More recent data have also shown an elevated impact of mesothelioma and asbestos diseases in Ambler. For instance, Centers for Disease Control and Prevention data show Montgomery County ranked 12th in the nation for mesothelioma deaths between 1999 and 2020.

Asbestos Cleanup Efforts in Ambler, Pennsylvania

Cleanup and remediation efforts in Ambler began soon after the dangers became more publicly known in the 1970s. The Environmental Protection Agency (EPA) began cleaning up the asbestos waste sites in 1973.

Ambler had two separate sites added to the EPA’s Superfund program. Both sites were close to businesses, homes and schools. Anyone who lived or worked close to these sites may have risked asbestos exposure. The EPA currently monitors both sites.

Ambler Asbestos Piles Superfund Site

The Ambler Asbestos Piles Superfund site consisted of three asbestos-containing waste piles. Asbestos dumping at the site contaminated the air, soil, sediments and surface water.

In 1974, the EPA documented that the piles contained 1.5 million cubic yards of asbestos waste. The materials were spread out over more than 25 acres. The agency began cleanup in 1973, and it placed the site on the National Priorities List (NPL) in 1986.

The EPA cleanup included capping the asbestos piles. The organization also added a layer of dirt to allow plants to grow. Finally, the EPA fenced the area off and put up signs warning of the buried asbestos.

The EPA’s cleanup efforts finished in 1993. The Ambler piles were taken off the NPL in 1996. The EPA still monitors the site to protect the health of Ambler residents.

BoRit Asbestos Piles Superfund Site

The second Ambler Superfund site is the BoRit Asbestos Piles. Companies used this area for asbestos waste disposal from the early 1900s to the late 1960s.

In 2008, the EPA conducted an emergency cleanup at the BoRit site, and the agency added the site to the NPL. At 2.5 acres, the BoRit site was smaller than the Ambler Asbestos Piles.

The BoRit site sat adjacent to a reservoir and three separate waterways. The EPA was concerned asbestos could contaminate the water and spread the fibers downstream.

The EPA capped all the asbestos-containing materials. The agency also shored up the banks of the three waterways. The EPA completed the BoRit cleanup in 2017 and continues to monitor the area.

Are Ambler, Pennsylvania Residents Safe From Asbestos Exposure Today?

Studies of Ambler suggest current residents are safe. However, officials recommend residents stay out of restricted sites and follow safety regulations. These precautions may help residents reduce the risk of exposure.

Anyone who lived or worked in Ambler before the asbestos cleanup may be at risk. Asbestos exposure can cause someone to develop an asbestos-related disease. Symptoms for these diseases may not present until 10 or more years after exposure. Anyone with a known history of asbestos exposure may want to talk with their doctor. A physician can help monitor for symptoms of mesothelioma.
