Manganese levels tested high at another well, coming in at 1 mg/l compared to the .15 mg/l dictated by state statute. Sulfate levels had the biggest jump during the five-month period, going from 1,000 mg/l to 1,500 mg/l. State statutes call for groundwater levels no higher than 400 mg/l.
The chemicals could have a trickle-down effect if they seep into surface water, beginning with aquatic life, according to Mason.“You could start to see elevated concentrations in fish tissue, which would raise concerns about how much and how often humans would be advised to consume fish from that body of water,” he said in an email.
“Excess consumption of these materials could have harmful effects.”
Dynegy announced plans in December 2010 to “mothball” the coal-burning Vermilion Power Generation Facility near Oakwood by the end of the first quarter of 2011. The facility — made up of two turbine units — celebrated its 50th anniversary in 2006.
The 176-megawatt per hour coal-burning facility operates 24 hours a day, seven days a week and produces enough electricity to supply 40,000-50,000 customers. One of the turbines generates 77 megawatts of power an hour, while the other produces 105 megawatts an hour.
