From The Pueblo Chieftain (Chris Woodka):
Security will be able to use increased capacity in the Southern Delivery System pipeline to deal with contaminated well water in the Fountain Creek aquifer.
Security Water District reached an agreement with Colorado Springs Utilities to increase the amount of water transported through SDS in order to eliminate perfluoralkyl substances, or PFASs, in drinking water.
“The start of SDS could not have come at a better time,” said Roy Heald, Security Water general manager. “We always said SDS was being built to improve reliability to the existing water systems and the situation with PFASs in drinking water underscores that.”
SDS went online in April.
The cause of the PFAS contamination is unknown, but it typically finds its way into water systems through manufacturing processes or deicing at airports.
When contaminants were first detected, Security stopped using some wells and initiated voluntary watering restrictions.
Security, located south of Colorado Springs, historically blended equal parts well water and surface water. The majority of customers are not affected by PFASs, but in some parts of the district increased use of groundwater normally would be needed to meet summer watering demands.
Security also gets some of its water from the Fountain Valley Conduit, which, like SDS, pumps water from Lake Pueblo to El Paso County.
“We are pleased to work with our longtime SDS partner Security Water to help resolve the water contamination issues,” said Dan Higgins, Colorado Springs Utilities chief water services officer. “SDS is already showing how critically important it was for all the communities who partnered to build it.”
Meanwhile, here’s a report about the public meeting held yesterday about the problem from Bruce Finley writing for The Denver Post. Here’s an excerpt:
More than 1,000 people south of Colorado Springs packed a high school Thursday night and buffeted government officials with questions and concerns about an invisible toxic chemical contaminating public water supplies…
Colorado Department of Public Health and Environment officials repeated recommendations — especially for women and children, because they may be more vulnerable to the perfluorinated chemicals (PFCs) — to switch to other water as a precaution.
“You may or may not be getting your tap water from an area of concern,” CDPHE water-quality official Tyson Ingals told residents. “We have about 60,000 people in the areas of concern. We estimate 10,000 to 15,000 may be receiving water with PFCs above the level of the heath advisory.”
What about schools? residents asked. How long have people here been drinking water tainted with PFCs? What about property values? Should pets be drinking different water? Could organically home-grown vegetables be tainted?
Local utility officials in Widefield, Security and Fountain — all partially dependent on municipal wells drawing from tainted groundwater — assured residents they are intensifying efforts to dilute supplies by mixing in cleaner water piped from Pueblo, 40 miles to the south. A CDPHE preliminary health assessment has found elevated cancer in the area, but officials emphasized no link to PFCs has been established…
Officials from El Paso County, the CDPHE and the military now are looking more closely at contamination in the Widefield-Security-Fountain area. Of 43 private wells tested recently, county officials have received results from 37 tests, with PFC levels in 26 exceeding the EPA limit, spokeswoman Danielle Oller said.
In Security, all 32 municipal wells are contaminated, and water officials ranked the wells based on levels of contamination. One well where the level was nearly 20 times higher than an EPA health advisory limit has been shut down. Security officials urged voluntary cutbacks in lawn watering to reduce the need to use contaminated groundwater.
Security Water and Sanitation District manager Roy Heald has divided the city into three zones and said about 25 percent of residents live in a zone receiving water from contaminated wells. The residents in two other zones “are supplied water mainly from surface water sources,” Heald said…
Next week, utility officials plan to begin re-plumbing, installing new pipelines, trying to blend in more water from Pueblo into that zone and other areas…
Air Force representatives at the forum, where residents filled an auditorium, adjacent cafeteria and stood in hallways at Mesa Ridge High School, said the Air Force will pay $4.3 million to set up temporary treatment systems — while local utilities address the long-term implications of contaminated groundwater and a possible fix. Military airfields are suspected as a source of PFC contamination, and a broad investigation is planned, with drilling in October at Peterson Air Force Base east of Colorado Springs.
“Our short-term to mid-term solution is to use more surface water, which is not affected by these contaminants. Our mid-term to long-term solution will be to treat the groundwater,” said Heald, who met with Air Force officials and will continue those discussions. Security also has requested financial help from the EPA, CDPHE and elected officials.
“Security Water is a relatively small water district, and the costs of managing this issue is expensive for our customers,” Heald said.
Security residents typically pay about $25 a month for their water.
Widefield officials said they’ll set up a free bottled water distribution station — limiting residents to 10 gallons a week. They’re relying as much as possible on water from Pueblo, although they may draw from contaminated wells to meet peak demands during summer as temperatures rise.
Fountain utility officials planned to notify residents about PFCs in notices mailed along with July water bills. Fountain normally draws from eight municipal wells, all now contaminated with PFCs above the EPA limit, and has shifted to water from Pueblo while contract engineers search for a solution.
Yet Ingals from CDPHE pointed out that these cities “cannot function on surface water alone. … There are groundwater wells that are being pumped. … The wells kick on and off at different intervals. … Because it is not predicable, we cannot tell you that it always is safe…
CDPHE experts in February began a preliminary assessment of cancer rates in the area south of Colorado Springs and on June 30 completed a report showing elevated cancer rates. The CDPHE team found lung cancer rates 66 percent higher than expected, bladder cancer up 17 percent and kidney cancer up 34 percent. CDPHE officials emphasized there’s no clear link to PFCs…
The assessment looked at births from 2010-14 and all cases of 11 types of cancer from 2000-2014 in 21 census tracts covering Security, Widefield and Fountain. CDPHE researchers compared these with birth and cancer data from the rest of El Paso County.
They found no spike in low birth weights in the areas where water is contaminated with PFCs. But there were a higher-than-expected rates of lung, kidney and bladder cancers.
“Of these types of cancer, only kidney cancer has been plausibly linked to PFC exposure in human and laboratory animal studies,” Van Dyke said.
The increases may be explained by higher rates of smoking and obesity in the area. Smoking and obesity, CDPHE officials said, may be factors explaining the increased kidney cancer.
More coverage from The Colorado Springs Gazette (Jakob Rodgers):
Residents from across Security, Widefield and Fountain flocked to hear more than a dozen federal, state, local and military officials hold a town hall about the work being done to clean the water in the Widefield aquifer.
As the evening wore on, one question rose above the rest: Why must residents have to incur more costs for bottled water and home filters because of a problem that wasn’t their fault?
“Why does the consumer have to pay more?” one man asked, to applause. He received no answer…
Roughly 60,000 people are served by water districts pulling from the contaminated Widefield aquifer, most of whom are in Security, Widefield and Fountain, officials said Thursday.
However, the majority of those people receive clean surface water pumped in by the Pueblo Reservoir. About 10,000 to 15,000 people receive contaminated water from wells tapped into the aquifer – and even they sometimes receive clean surface water, depending on daily water usage, a state health official said.
In general, those affected homes are along the western portions of Security and Widefield. Fountain has switched to clean surface water…
Throughout the meeting, officials stressed they are doing all they can to fix the problem.
Within a month, the Widefield Water and Sanitation District plans to set up a water dispensing site, allowing residents along the western portions of Widefield to receive up to 10 gallons of water a week. It is also working on a construction project to pump in more surface water.
Security officials announced a deal Thursday with Colorado Springs Utilities to increase the amount of Southern Delivery System water it will receive.
The project, which could take three months to complete, will likely end the community’s reliance on well water until a more permanent solution can be implemented. It might, however, come at the cost of higher water rates next year, the district’s water manager said.
Fountain officials also are working on a treatment plant.
