Note: This is just part one; more to come.
Dr. Dennis Lemly, a biologist with Wake Forest University and the U.S. Forest Service, began investigating coal ash on the Dan River in the 1970s when he realized that the fish he was trying to study were dying. He found that a Duke Energy coal ash impoundment at its Belews Creek plant was polluting the river, and because of it 19 of 20 species of fish died.
Listen to Lemly explain his work and his concerns about coal ash in this unedited interview. I also suggest you look into his published studies, reports, and articles.
It took about a year and a public thrashing to get this interview with Dr. Lemly. (Background: http://www.coalashchronicles.com/journal-entry/vent-over-my-dead-body-will-i-script-an-interview-u-s-forest-service)

Laboratory analysis of the discharge (visible on this map at point “D”) confirmed that it contains multiple pollutants that are characteristic of coal ash, including the toxic heavy metals arsenic and chromium. Arsenic concentrations measured .187 mg/L, more than 18 times the human health standard and over 3 times the applicable water quality standard. Meanwhile on Wednesday, Duke Energy began vacuuming ash from last week’s spill out of the river, and pumping it back into the leaking impoundment.
It took more than a billion gallons of toxic waste pouring into Tennessee’s Emory River in 2008 to wake federal and state regulators up to the growing problem of disposing and storing coal ash, the by-product of burning coal.
That spill, which has now cost more than a billion dollars to clean up, led to the realization that the country had more than a thousand ponds, half unlined, holding coal ash and toxins seeping through the ground and leaching into drinking water supplies.
That includes 37 ponds in North Carolina, 29 of which the Environmental Protection Agency has rated “high hazard” — where a spill has the potential for catastrophic damage and loss of life. Sixteen of those sites have been identified as contaminated.
Read the entire article.
Important to understand: The groundwater near every unlined coal ash pond in North Carolina was contaminated before the Dan River coal ash spill. (Report.)
Now, keep in mind that the coal industry made a deal with the EPA in 2000 that it would self-monitor groundwater at its coal ash ponds in exchange for the agency NOT regulating coal ash. Unfortunately, some of those groundwater wells weren’t sunk until the same month as the 2008 TVA coal ash disaster.
In 2010, N.C. forced Progress Energy and Duke Energy (now the same company) to sink more groundwater monitoring wells. So, much of the information we have about groundwater contamination is relatively recent but unfortunately not readily available.
A little background:
The N.C. Department of Environment and Natural Resources responded via email, which is pasted here:
Easier to email this than tweet it.
A discussion of the impacts to groundwater from the Duke Energy Dan River power station ash ponds can be found on the DENR website section that deals with the department’s motions for injunctive relief:
The link for Duke Energy Carolinas, LLC Complaint and Motion for Injunctive Relief takes you to this file:
The section on the Dan River Combined Cycle Station begins on page 28 of that file. This is where we have a discussion of groundwater impacts.
The plant has recorded exceedances of groundwater standards at or beyond the compliance boundary for antimony, arsenic, boron, iron, manganese, total dissolved solids, and sulfate. A chart of exceedances data for this facility is available as Exhibit No. 10 - http://portal.ncdenr.org/c/document_library/get_file?uuid=972f054e-5ca9-4b59-ae63-90dfda3d9c32&groupId=38364
It is my understanding there are no drinking water wells in the vicinity.
Let me know if you need anything else.

Thank you, Michelle. I’m sorry it has taken me so long to return your email.
I’d like to get the groundwater sampling results from Duke Energy’s Dan River plant. I’m not sure how often they’re submitted – I know that they’re submitted quarterly for the Riverbend plant near Charlotte, so I’m assuming it’s something like that. I’ll tell you that when I first requested Riverbend’s groundwater numbers, NCDENR told me I had to come to Raleigh to get them and then made me pay to copy them … so, I did. Not long after that, I met with Sen. Kay Hagan’s office and told them that story; they let me know that they’d back me up if that ever happened again.
So, I’m asking once more: Please email me the groundwater sampling results for Dan River’s coal ash ponds for as long as NCDENR has record of them. Please.
And thank you.

You know I’ll update you once I hear back.

Subject: Belews Creek + Eden’s water supply + bromide
I’ve heard from someone at the Eden water treatment plant, upstream of the spill. I asked him if he had anything to worry about from the spill. He said no, not from that spill, but what they have to worry about is the bromide that comes down from Belews Creek’s ash discharge. Although Eden hasn’t had to treat for bromide yet, he said Duke is about to start paying for some water treatment for bromide.
Is this true?
Bromide leaves the Belews Creek plant from its scrubber process to meet air quality standards. Bromide itself is not a health concern in the river, but when it reacts with the chlorine in the municipal water treatment process, it can contribute to forming trihalomethanes (TTHMs) that are regulated for the drinking water supply.
Many water systems nationally with no bromide in their source water also experience elevated TTHMs because of warmer temperatures, higher organic content in water and lower turnover of treated water in pipes, among other factors. We felt participating in a solution was the right thing to do, and Duke Energy has been partnering with the city for a few years to research different options. We also are helping to fund the city’s conversion to another disinfection method. There is no federal or state surface water quality standard for bromide and, therefore, no limit in the plant’s permit for it.
The city of Eden’s drinking water meets all state and federal drinking water standards, and this is a proactive step to ensure it meets more stringent standards in the future.

And, I’m assuming – because that’s how it reads – that you’re doing this without being forced to by regulation or legislation, is that correct?
Thank you for filling me in on this, Erin.
Yes, that’s correct. Thanks.

Shortly before 1:00 AM on December 22, 2008, more than 1 billion gallons of toxic coal ash inundated hundreds of acres of the Emory River and surrounding landscape, including dozens of homes. ‘Ashbergs’ steeped metals into the water. Here in the Catawba-Wateree basin, we have fought and continue to fight to make sure the same could never happen here. Were such a spill to happen on Lake Norman, Mountain Island Lake (MIL), or Lake Wylie, the results would be orders of magnitude more catastrophic for the area’s drinking water supply, environment, economy, recreation and more. The blessings of Kingston were that no one was killed, and the rural nature of the location did not cause a drinking water crisis as seen in West Virginia.
"Even without a spill, these settling ponds have been releasing continuous contamination into the rivers downstream from coal-fired power plants," said Avner Vengosh, a professor of geochemistry at Duke University, which was named for the same family that founded the power company.
WASHINGTON The chemical spill that contaminated water for hundreds of thousands in West Virginia was only the latest and most high-profile case of coal sullying the nation’s waters.
Faced with state and advocates’ lawsuits, Duke Energy is beginning to waver on its long-held assertion that coal ash stored at its North Carolina power plants doesn’t threaten public health.
Excerpt from Sam Perkins, the Catawba Riverkeeper:
More and more, we are learning how much Duke Energy’s coal ash pollution is threatening drinking water supplies throughout North Carolina. What we are seeing in the state makes clear that Duke Energy must get its polluting coal ash off the banks of the Catawba River’s Mountain Island Lake, the drinking water reservoir for the Charlotte metropolitan region.
The problem is so extensive that every Duke coal ash pond in North Carolina is now the subject of a lawsuit. To the west, in Asheville this past week, the N.C. Department of Environment and Natural Resources ruled that Duke needs to provide alternative safe drinking water to a home with a well contaminated by high levels of coal ash pollution from nearby coal ash ponds. At Mountain Island Lake on the Catawba River, testing by the Catawba Riverkeeper and Duke’s own groundwater monitoring wells have revealed the same contaminants as in Asheville at more than 10 times the Asheville level and 128 times the state groundwater standard (for manganese, a neurotoxin) – as well as cobalt at 52 times the standard and arsenic at twice the standard – and going into our drinking water reservoir.
