TVA Fossil Plants Report Groundwater Contamination


By: Duane Craig

Tennessee Valley fossil-fuel plants contaminating groundwater

The Tennessee Valley Authority, operator of 21 fossil fueled power plants, three nuclear power plants, 29 hydroelectric dams, 14 solar power generation sites, 18 wind turbines and one methane-assisted fossil fuel power plant, has been told by its own inspector general that eight of nine fossil-fueled plants with groundwater monitoring had contaminants in the groundwater that exceeded federal limits.
The OIG also said the TVA, a wholly-owned but self-funded agency of the U.S. government, was in some cases not performing the monitoring required by its permits.
Two plants named in the OIG's report were placed on the highest severity assessment for exceeding a health based groundwater protection standard. The Cumberland plant, northwest of Nashville, was one of those, and Gallatin was the other. Both plants are on the Cumberland River.
Two other plants, Bull Run and John Sevier were placed on Phase II assessment for a significant increase in contaminants above the background levels. Bull Run is near Oak Ridge, Tennessee and the John Sevier plant is near Rogersville, Tennessee. According to its own account, the John Seveir plant released more than 5,000 pounds of toxins into water there in 2009, including nickel compounds, lead compounds, copper compounds, chromium compounds, barium compounds, arsenic compounds and ammonia. The plant also released 31 million tons of carbon dioxide, nitrogen oxides and sulphur dioxide into the air in 2010.

CT Well Contamination Woes

October 10, 2010 - A resurgence of a long-standing neighborhood contamination problem has forced several Harwinton Avenue residents to abandon their wells for drinking water, and neighbors are calling for a water line as a long-term solution.

Wells at nine homes tested positive for contaminants including lead, arsenic, nickel and cadmium after the Department of Environmental Protection sampled them earlier this year. Dismayed at the prospect of a future of state-supplied bottled water and water filters, residents attended a meeting with the mayor and representatives of the DEP and the Torrington Area Health District late last month.
