environmental Strategist™, between the lines: My question after you read the article below is how many contaminated sites don’t we know about?
Under CERCLA you are responsible for the environmental condition of your property. What if a third party contaminates your property and they do not have the financial ability to correct the problem? Your asset has just become a liability.
Contamination from third parties can come from air, water, soil, ground water or just over the surface of the land and below are real life examples.
While this article points out that 25% of Superfund sites are on Tribal land, the other 75% represent and even greater impact on human health and the environment.
Environmental Strategist™ Risk Management Tip: Environmental insurance can protect real estate owners if third parties contaminate their property.

Kill the Land, Kill the People: There Are 532 Superfund Sites in Indian Country!
Terri Hansen: Indian Country Today – 6/17/14
Of a total of 1,322 Superfund sites as of June 5, 2014, nearly 25 percent of them are in Indian country. Manufacturing, mining and extractive industries are responsible for our list of some of the most environmentally devastated places in Indian country, as specified under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the official name of the Superfund law enacted by Congress on December 11, 1980.
Most of these sites are not cleaned up, though not all of the ones listed below are still active. Some sites are capped, sealing up toxics that persist in the environment. In cases like the Navajo, the Akwesasne Mohawk and the Quapaw Tribe, the human health impacts are known because some doctors and scientists took enough interest to do studies in their regions. Some of those impacts may persist through generations given the involvement, as in the case of the Mohawk, of endocrine disrupters.
TheSalt Chuck Mine Superfund site in southeast Alaska operated as a copper-palladium-gold-silver mine from 1916 to 1941. Members of the Organized Village of Kasaan, a federally recognized tribe, traditionally harvested fish, clams, cockles, crab and shrimp from the waters in and around Salt Chuck, unaware for decades that areas of impact were saturated with tailings from the former mine. As if that weren’t enough, Pure Nickel Inc. holds rights to mining leases in the area and began active exploration to do even more mining in summer 2012, according to Ground Truth Trekking.
The Elem Band of Pomo Indians, whose colony was built on top of the waste of what would become California’s Sulfur Bank Mine Superfund site in 1970, have elevated levels of mercury in their bodies, and now fear for their health. According to an NBC News investigation, nearby Clear Lake is the most mercury-polluted lake in the world, despite the EPA’s spending about $40 million over two decades trying to keep mercury contamination out of the water. Although the EPA cleaned soil from beneath Pomo homes and roads, pollution still seeps beneath the earthen dam built by the former mine operator, Bradley Mining Co. For years, Bradley Mining has fought the government’s efforts to recoup cleanup costs.
The Washoe Tribe of Nevada and California requested EPA involvement in the cleanup of an abandoned open pit sulfur mine on the eastern slope of California’s Sierra Nevada that became the Leviathan Mine Superfund site. The Washoe Tribe had become concerned that contaminated waters were affecting their lands downstream, causing impacts to culture and health, environmental damage, remediation, monitoring and testing, posting of health advisories, drinking water, effects on pregnancy, and cancer. Aluminum, arsenic, cadmium, iron, manganese, nickel and thallium have beendetectedin surface water and sediment downstream from the mine. The U.S. Centers for Disease Control and Prevention (CDC) concluded that exposures could result in cancerous and non-cancerous health effects.
The abandoned FMC phosphorus facility occupies more than 1,000 acres of the Shoshone-Bannock Tribes’ Fort Hall Reservation in Idaho, and lies within Eastern Michaud Flats Superfund site. The primary contaminants of concern at the site are arsenic, elemental phosphorous and gamma radiation. FMC left a legacy of contamination in the air, groundwater, soil and the nearby Portneuf River, which threatened plants, wildlife and human health on the reservation and in surrounding communities. The Shoshone-Bannock have long asked for a cleanup of contaminated soils, but instead the EPA’s 2012 interimremedyis to cap and fill, including areas containing gamma radiation and radionuclides.
