This week, Hydroviv is highlighting the six new National Priorities List (NPL) sites under the EPA Superfund program. Superfund sites are home to high levels of hazardous soil and groundwater contamination from years of improper disposal techniques. If you’d like to learn more about the ins and out of Superfund, check out our recap HERE. The next Superfund site that we’ll be discussing is located in Spencer, Indiana. 

Spencer, Indiana is home to another newly designated Superfund site. The municipal well field is a contaminated chlorinated solvent plume, with levels exceeding federal standards for Tetrachloroethylene or PCE. In a 2012 carcinogenicity assessment, EPA set a Maximum Contaminant Level (MCL) of 5 parts per billion for drinking water. Long term exposure of PCE can cause adverse effects to the liver, kidneys and central nervous system. The Indiana Department of Environmental Management has yet to identify a responsible party for the contamination, but they have recognized 9 active and closed facilities that could be major contributors.

If you’d like to learn more about the ins and out of Superfund, check out our recap HERE. The next Superfund site that we’ll be discussing is located in Spring Park, Minnesota. 

Spring Park, Minnesota is home to one of the six newly designated Superfund sites. The town’s municipal well field is contaminated with several industrial solvents such as trichloroethylene (TCE), 1,2-dichloroethylene (DCE) and vinyl chloride. There are 1,673 residents in Spring Park, all of which are serviced by the same municipal well field. Two of the three municipal wells currently exceed Maximum Contaminant Levels for TCE. EPA has stated that the source of the contamination is unknown, but all contaminants are frequently used as industrial solvents.

This week, Hydroviv is highlighting the six new National Priorities List (NPL) sites under the EPA Superfund program. Superfund sites are home to high levels of hazardous soil and groundwater contamination from years of improper disposal techniques. If you’d like to learn more about the ins and out of Superfund, check out our recap HERE. The Superfund site that we’re addressing in this article is located in San Antonio, Texas.  

San Antonio, Texas is home to another newly designated EPA Superfund site. EPA detected high levels of cyanide, lead, cadmium, copper, selenium, zinc, chromium, and chromium 6. The source of contamination is from the River City Metal Finishing facility, which was in operation from 1994 to 2002. Throughout operation and post closure, runoff and pollution from this facility entered into the Edwards Aquifer which provides domestic, industrial and agricultural water for a majority of San Antonio. Concentrations of chromium 6 exceeded federal maximum contaminant levels in shallow groundwater wells in the Edwards Aquifer. There are several adverse health effects associated with chromium 6 exposure. Aside from being a known human carcinogen, ingestion of chromium 6 can cause respiratory irritation, pulmonary congestion and edema, and damages to the kidney, liver, and skin. There are currently 20 public water supplies with a 4 mile radius of the San Antonio Superfund site.

This week, Hydroviv is highlighting the six new National Priorities List (NPL) sites under the EPA Superfund program. Superfund sites are home to high levels of hazardous soil and groundwater contamination from years of improper disposal techniques. If you’d like to learn more about the ins and out of Superfund, check out our recap HERE. The next Superfund site that we’ll be discussing is located in Cheraw, South Carolina.

Cheraw, South Carolina is home to another newly designated national Superfund site. This small town is home to roughly 6,000 people. EPA detected high levels of Polychlorinated Biphenyls, or PCBs in the sediment in residential neighborhoods and in nearby water streams. The source of this contamination is linked to a nearby textile mill. The water in Cheraw became contaminated because the facility created a drainage ditch was used to dispose of wastewater. Contaminated water from the drainage ditch infiltrated into groundwater, and was also transported onto residential lawns through stormwater runoff. Runoff also transported chemicals into surrounding wetlands and into the Grand Pee Dee River, the Wilson Branch Stream, and the Huckleberry Branch Stream. As a result, the state has issued a fish consumption advisory for all fish caught in the Grand Pee Dee River due to the high levels of Polychlorinated Biphenyls (PCBs). PCB is a carcinogen and can adversely affect pregnant women, children, and other sensitive populations. For more information about PCBs please check out our site at hydroviv.com.

This week, Hydroviv is highlighting the six new National Priorities List (NPL) sites under the EPA Superfund program. Superfund sites are home to high levels of hazardous soil and groundwater contamination from years of improper disposal techniques. If you’d like to learn more about the ins and outs of Superfund, check out our recap HERE. The first Superfund site that we’ll be discussing is located in Hockessin, Delaware.

Hockessin, Delaware is home to one of the six newly designated Superfund NPL sites. EPA detected high levels of Tetrachloroethylene (PCE) on site, which is a known carcinogen. In a 2012 carcinogenicity assessment, EPA set a Maximum Contaminant Level (MCL) of 5 parts per billion for drinking water. Long term exposure of PCE can cause adverse effects to the liver, kidneys and central nervous system. The Artesian Water Authority services 184,000 people in Hockessin, and government officials are predicting that 10,500 of these individuals may be affected by the contamination. Local officials claim that the tap water is “safe” to drink, but households that are not serviced through the Artesian Water Authority and those ingesting groundwater should be cautious. Currently, EPA is claiming that the source of contamination is unknown. PCE is an effluent typically associated with dry cleaning, textile operations and metal degreasing.
