From The Denver Post (Bruce Finley):
The spill, which Air Force officials said they’re investigating, happened as the Air Force increasingly faces scrutiny as a source of groundwater contamination nationwide.
The surge of waste containing elevated perfluorinated chemicals (PFCs) — used at military airfields to douse fuel fires and linked by federal authorities to kidney cancer, testicular cancer, low birth weights and other health problems — flowed through a Colorado Springs Utilities wastewater treatment plant before crews could try to block it. Then it trickled into Fountain Creek.
“Even if we would have been able to head it off at the plant, we’re not equipped. I don’t know of any wastewater plants in the country equipped to remove PFCs,” utilities spokesman Steve Berry said. “We would not have been able to remove that chemical before it was discharged back into the environment from our effluent.”
Fountain Creek flows south toward Pueblo and into the Arkansas River.
Pueblo Board of Water Works spokesman Paul Fanning said Pueblo didn’t hear about the spill until reporters made inquiries Tuesday.
“We don’t use any groundwater or surface water from Fountain Creek. We use water from the Arkansas River taken upstream from where Fountain Creek flows in,” Fanning said. “But it is not a good thing to have those contaminants anywhere in our water. There are some reported health effects. It is in our interest to protect our public.”
The PFC-laced waste was held in a tank at a firefighter training area on the base, located at the southeastern edge of Colorado Springs. PFCs are a component in the aqueous film-forming foam used to extinguish fuel fires.
Air Force officials said in the statement that they discovered the spill Oct. 12 during an inspection. They notified Colorado Springs Utilities the next day. The tank was part of a system used to recirculate water to a firefighter training area…
In Colorado, government well test data show PFCs have contaminated groundwater throughout the Fountain Creek watershed, nearly as far south as Pueblo, at levels up to 20 times higher than that EPA health advisory limit of 70 parts per trillion.
Public-water authorities in Fountain, Security and Widefield have scrambled to provide enough alternative water. Security has been purchasing millions of gallons of diverted Arkansas River water from Colorado Springs, installing new pipelines and minimizing pumping from contaminated municipal wells. Since Sept. 9, Security has not pumped any water from wells, water and sanitation district manager Roy Heald said. “This spill does not affect us immediately,” Heald said. “Our only concern would be the long-term effect on Fountain Creek and the Widefield Aquifer.”
Some parents south of Colorado Springs began paying for bottled water — to be safe. A contractor delivers emergency bottled water to at least 77 households.
The Air Force has contributed $4.3 million to help communities deal with the contamination.
Colorado Springs utilities crews will work with the military “to keep PFCs out of our system. That is the goal,” Berry said. “How do we protect our customers and our system from this chemical? That is the focus. It goes beyond the Air Force. It is any industrial process that may use that chemical.”
El Paso County Public Health “takes this discharge seriously and will coordinate with the Colorado Department of Public Health and the Environment to collect water samples along Fountain Creek, if warranted,” spokeswoman Danielle Oller said.
CDPHE has been informed, agency spokesman Mark Salley said, adding: “It is under investigation by the Air Force, and the department is waiting for information. … The Air Force has demonstrated its commitment to identifying and addressing PFC contamination at Peterson Air Force Base and facilities nationwide.”
From The Colorado Springs Gazette (Tom Roeder and Jakob Rodgers):
The release last week posed no threat to Colorado Springs drinking water.
The base said the release was discovered Oct. 12. The cause hasn’t been determined, but Fred Brooks, Peterson’s environmental chief, said the holding tank was designed to be difficult to discharge.
“It’s not a direct connection,” Brooks said. “This tank would have to have numerous valves switched to actually discharge.”
Was it intentional?
“That’s a possibility,” Brooks said…
An investigation has been opened to determine the cause of the discharge, said Col. Doug Schiess, who commands Peterson’s 21st Space Wing, in the statement.
Colorado Springs Utilities said the chemical-laden water passed through the utility’s Las Vegas Street sewage treatment plant and was released into Fountain Creek. The plant does not have the capacity to remove the chemical.
“There was no risk to the drinking water,” said Steve Berry, a Utilities spokesman. “This did not impact the drinking water, the finished water system, in any way. It went directly into the wastewater system.”
While Peterson notified Colorado Springs, base officials didn’t warn others downstream. Brooks said the base isn’t required to issue a wider notification, noting that the chemical is “unregulated” – a term used for substances that haven’t drawn enforceable drinking water standards…
Peterson had scheduled a public firefighting demonstration on Oct. 12, the day the discharge was discovered. The fire training exercise was canceled, with a spokesman at the base blaming the delay on a “bad valve”
Brooks, the base environmental officer, said two mechanical valves and an electric one must be switched to allow water to flow out of the tank, which held the outflow from fire training exercises dating back as far as 2013.
He said the water wasn’t tested for levels of the firefighting chemical.
A second tank on the base holding fire training residue wasn’t discharged.
The Air Force banned use of the foam outside fire emergencies last year and last month announced a plan to replace the product at all of its bases around the globe. Brooks said the foam at Peterson will be replaced in about two weeks.
The water contamination in Security, Widefield and Fountain has drawn a pair of lawsuits against the manufacturers of the firefighting foam alleging they sold it to the Air Force despite its toxic risks.
Although downstream, no drinking water supplied to Pueblo residents by the Pueblo Board of Water Works comes from Fountain Creek, said Paul Fanning, the agency’s spokesman. The Pueblo Reservoir does not pull from Fountain Creek.
The Widefield Water and Sanitation District is the only water system immediately downstream of the treatment plant now using the Widefield Aquifer, which leaches water from Fountain Creek, where the chemicals flowed.
Widefield officials have previously said they plan to shut off their wells by sometime in October.
Other communities have shut off their wells to the tainted aquifer.
All the water flowing to homes supplied by the Security and Fountain water systems now comes from the Pueblo Reservoir – meaning that last week’s spill should not affect those communities.
“The long-term effects would be concerning,” said Roy Heald, Security water district’s general manager. “But short-term immediate effects – there wouldn’t be any for us.”
The EPA said it wasn’t involved with the spill.
The Colorado Department of Public Health and Environment gave the Air Force a vote of confidence despite the chemical discharge.
“The Air Force has demonstrated its commitment to identifying and addressing (perfluorinated compound) contamination at Peterson Air Force Base and facilities nationwide,” the state agency said.
