The Most Hazardous Contaminated Places and Where They Are

The Most Hazardous Contaminated Places and Where They Are

The Environmental Protection Agency created the Superfund program in 1980 to clean up some of the nation’s most contaminated land and respond to environmental emergencies, oil spills, and natural disasters. 

The goals of the Superfund are to protect the health of people and the environment by cleaning up contaminated sites; make those responsible pay for the cleanup work; get communities involved in the process; and return the sites to productive use. Cleaning up toxic waste is a hazardous business. Here are the most dangerous jobs in America.

24/7 Tempo reviewed data from the Environmental Protection Agency to determine the most hazardous contaminated places and where they are.   

As of Nov. 8, there were 1,335 Superfund sites in the United States and its territories. New Jersey, the nation’s fifth-smallest state, has the most Superfund sites with 114, a vestige of its heavy industrial past. North Dakota has no Superfund sites. The Superfund sites include previous manufacturing facilities, processing plants, mining sites, and landfills. These are the countries that produce the most waste.  

The Superfund program was created following much-publicized stories about hazardous waste in the late 1970s — such as the notorious Love Canal disaster near Niagara Falls, New York, where toxic industrial waste bubbled up into backyards and cellars. Mining and the early days of the Industrial Revolution have left a toxic legacy that still needs to be remedied today.

23. Kerr-McGee Chemical Corp – Jacksonville
> Hazard Ranking System score: 70.7
> Location: Jacksonville, Florida
> Listing Date 3/4/2010

The Kerr-McGee Chemical Corp. is a 31-acre Superfund site on the west bank of the St. Johns River near the port area of Jacksonville. The site is where the company produced fertilizer and pesticides for 85 years until 1978. The EPA put the site on the Superfund list in 2010 because of tainted soil and groundwater but said the contaminated area does not pose a threat to those living and working at the site. The Florida Department of Environmental Protection and Tronox, the successor to Kerr-McGee, have taken action to shield people and the environment from contamination.

12. Centredale Manor Restoration Project
> Hazard Ranking System score: 70.7
> Location: North Providence, Rhode Island
> Listing Date 2/4/2000

The Centredale Manor Restoration Project, located about four miles northwest of Providence, Rhode Island, is the site of chemical manufacturing and drum reconditioning operations that took place from the early 1940s to the early 1970s. A fire destroyed most of the structures there in 1972. Because of previous operations at the site chemicals seeped into the ground and fed into the Woonasquatucket River and tainted sediment, streams, and ponds. EPA investigations from 1999 to 2012 revealed contamination of soil, groundwater, sediment, and surface water that contained dioxin and polychlorinated biphenyls, compounds the EPA regards as hazardous. The EPA took cleanup action from 1999 to 2002 and brought litigation against responsible parties that resulted in a $100 million cleanup plan in 2018.

7. Industri-Plex
> Hazard Ranking System score: 72.4
> Location: Woburn, Massachusetts
> Listing Date 9/8/1983

There has been some type of manufacturing plant at the Woburn, Massachusetts, site since the mid-1800s, at the dawn of the Industrial Revolution. From 1853 to 1931, the site was used to make manufacturing chemicals such as lead-arsenic insecticides, acetic acid, and sulfuric acid for textile, leather, and paper manufacturing companies.

The soil became contaminated from the residue from arsenic, lead, and chrome. Later, the site was used to manufacture glue from raw animal hide until 1969. The residue from the hides and the release of hydrogen sulfide gases from the hides created a toxic environment threatening residences within 3 miles of the site. Cleanup has consisted of two longer-term remedial efforts to stabilize the site and the cleanup of groundwater contamination. Cleanup began in 1986 and continues today.

6. Helen Kramer Landfill
> Hazard Ranking System score: 72.7
> Location: Mantua Township, New Jersey
> Listing Date 9/8/1983

Mantua Township is located about 16 miles southeast of Philadelphia. A sand and gravel pit originally operated at the 66-acre site, which became a landfill in the early 1960s until it closed in 1981. During that time, various wastes were disposed there, such as municipal wastes, septage, and industrial wastes that contaminated groundwater with hazardous chemicals. After the site was placed on the EPA’s National Priorities List in 1983, cleanup commenced. A five-year review report issued by the EPA in September 2015 found that the cleanup effort protects people and the environment. An evaluation to ensure groundwater migrating towards Edwards Run is effectively contained still has to take place.

3. Washington County Lead District – Old Mines
> Hazard Ranking System score: 76.8
> Location: Old Mines, Missouri
> Listing Date 3/19/2008

Washington County Lead District – Old Mines is about 65 miles south of St. Louis and is part of the Old Lead Belt, where lead has been mined for hundreds of years. Eighty percent of America’s lead used to come from this region. Groundwater, soil, surface water, and sediment have been tainted by arsenic, barium, cadmium, and lead. Over time, residences have been built near the site, and there is concern drinking water and soil have been contaminated. The EPA began to clean lead-tainted soil at a school, and the agency had to provide water filtration devices for homes where the presence of lead in water exceeded the unhealthy levels. The EPA is looking to provide an alternate source of drinking water for affected residents.

2. Washington County Lead District – Richwoods
> Hazard Ranking System score: 76.8
> Location: Richwoods, Missouri
> Listing Date 3/19/2008

Washington County Lead District – Richwoods Old Mines, is about 57 miles south of St. Louis. The 45-square-mile area is another part of the region’s Old Lead Belt. It also shares the legacy of tainted groundwater, soil, surface water, and sediment by arsenic, barium, cadmium, and lead. Residences have been built over mine waste, and some residents, unaware of the health implications, have even used the waste for gravel driveways. There is concern that drinking water and soil have been contaminated. The EPA has provided water filtration devices for homes where the presence of lead in the water exceeds the healthy levels. According to the EPA, one in seven drinking water supply wells qualify for a water filtration system.

1. Big River Mine Tailings/St. Joe Minerals Corp.
> Hazard Ranking System score: 84.9
> Location: Desloge, Missouri
> Listing Date 10/14/1992

Big River Mine Tailings/St. Joe Minerals Corp., 62 miles southwest of St. Louis, is the third of three Superfund sites on the list located in the Old Lead Belt in Missouri. The site includes eight big sections of mine waste, about 110 square miles. In 1977, as a result of torrential rains, about 50,000 cubic yards of sludge containing mining waste to drifted into the Big River. Besides lead, other minerals such as cadmium and zinc were present. Because of raised lead levels, people were advised not to eat fish caught downstream from the Big River. The eight areas of mine waste are being stabilized to prevent sloughing. The cleanup process began in 1995.

Methodology

24/7 Tempo reviewed the 23 Superfund sites determined to be the most hazardous, based on the site’s assigned Hazardous Ranking System (HRS) score determined by the Environmental Protection Agency. Any score higher than 28.5 is deemed a serious enough hazard by the EPA to merit Superfund spending. 

The EPA determines the HRS of a site based on three main categories of risk: The likelihood that a site is releasing — or has the potential to release — hazardous substances into the environment; the toxicity of the waste and how much of it there is; and the proximity of the waste to people. It is important to note that these sites are being cleaned, and some have had their contaminants removed since the HRS assessment grade listed was made.
