An innovative water-sharing partnership between Denver Water, Aurora Water and water utilities that serve the south metro area has won national recognition.
The WISE Partnership, WISE being short for Water Infrastructure and Supply Efficiency, recently brought home a “Community Water Champion Award” from WateReuse, a national organization that advances the use of recycled water.
The award marks another sign of success for a project that showcases sustainability on multiple fronts.
WISE not only provides a way for Denver and Aurora to reuse water supplies, it also creates a dependable supply for 10 water providers that serve the south metro region.
That more dependable supply, in turn, reduces pressure to pull more water from the Colorado River, conserves dwindling groundwater supplies south of Denver and diminishes the need for metro area utilities to buy agricultural water in the South Platte River Basin, which can lead to drying up farmland if the water is diverted…
The unusual nature of the WISE project may have helped it capture the national award.
Awards typically recognize a specific facility, such as a water recycling plant, or a technology. WISE includes such features, but also leverages the power of a regionwide partnership to make it all work.
WateReuse described the award this way: “This innovative regional partnership for a sustainable water future will reduce groundwater reliance and bolster renewable water supplies to the South Metro area, while maximizing existing water assets belonging to Aurora and Denver Water.”
WISE works by pulling water that Denver and Aurora have a legal right to reuse from the South Platte River near Brighton. That water is then pumped via pipeline back upstream to Aurora for a series of treatment steps before distribution to project partners…
Simply put, the project’s benefits accrue this way:
Denver Water develops a new water supply by being able to use Aurora’s Prairie Waters system and a new revenue stream by selling unused water to the south metro area water providers.
Aurora Water benefits by selling unused water and putting unused treatment and pipeline capacity to use while receiving revenue that helps keep its water rates down.
The South Metro Water Supply Authority receives a permanent renewable water supply, helping to reduce its reliance on nonrenewable groundwater.
FromThe Chaffee County Times (Max R. Smith) via The Leadville Herald:
In the mid-1960s, a partnership between the cities of Colorado Springs and Aurora installed a diversion dam in the Arkansas River south of Granite near Clear Creek Reservoir as part of a pipeline system bringing water from the western slope of the Continental Divide to the Front Range.
The presence of the diversion dam caused that portion of the river to be non-navigable, requiring portaging of one’s raft or kayak.
By the end of this year, however, Colorado Springs Utilities is on schedule to complete a three-year project to build a new river diversion that will allow boaters to float right through, meaning that the 2020 rafting season will be the first in over 50 years in which the entirety of the Arkansas can be travelled without portage.
“We’ll see how the snow treats us over the next couple weeks, but we’re really down to some final boulder work in the river and general site cleanup at this point,” said CSU project manager Brian McCormick.
The intake that pumped water out of the Arkansas (which, legally speaking, comes from the Eagle River Basin as part of the Homestake Project), destined for Aurora and Colorado Springs, “as with anything in the river for 50-plus years, it took some wear and tear,” McCormick said. “By about the mid-2000s, the cities recognized we needed to rehabilitate this structure to keep it as a reliable facility and ensure safety of the river users.”
Construction on the new $9.1 million diversion project began in 2016 after a number of years of planning, budgeting, and engineering. Support for the project included $1.2 million in grant funding from the Arkansas Headwaters Recreation Area, Colorado Parks and Wildlife and the Colorado Water Conservation Board…
Significant to water consumers in Colorado Springs and Aurora, the project utilizes a new intake and piping structure to send water to the Otero pump station, he said.
Significant to boaters is a chute constructed of boulders and mortar with six two-foot drops that will allow them to pass the intake facility without exiting the river. McCormick said that CSU put the call out to members of Colorado’s river recreation community to participate in a trial run down the chute in November, testing the Arkansas’s newest whitewater feature…
Significant to the scaled, Omega-3 rich denizens of the Arkansas who swim upstream to spawn every year, the new diversion also features a fish ladder: a sequence of weirs and pools that give brown and rainbow trout a route to move up the river to their spawning grounds.
One morning last month, Brad Johnson arrived at a patch of rippling yellow grasses alongside U.S. 24, a few miles south of Leadville in the upper Arkansas River valley. Sandwiched among a cluster of abandoned ranch buildings, a string of power lines and a small pond, it is an unassuming place — except, of course, for its views of 14,000-foot peaks rising across the valley.
But appearances can be deceiving. The rather ordinary-looking property was a fen, which is a groundwater-fed wetland filled with organic “peat” soils that began forming during the last ice age and that give fens their springy feel.
“It’s like walking on a sponge,” Johnson said, marching across the marshy ground, stopping every now and then to point out a rare sedge or grass species.
Johnson was visiting the fen to record groundwater measurements before winter sets in. As the lead scientist for the Rocky Mountain Fen Research Project, Johnson is part of an effort spearheaded and paid for by Aurora Water and the Board of Water Works of Pueblo to study new ways to restore fens.
The research could help facilitate future water development in Colorado, such as the potential Whitney Reservoir project, part of a 20-year water-development plan from Aurora Water and Colorado Springs Utilities for the upper Eagle River watershed. The utilities, working together as Homestake Partners, are looking at building the reservoir in the Homestake Creek valley, south of Minturn, in an area that probably contains fens, which could hinder the project.
Aurora and Colorado Springs are working together on the reservoir project, and Aurora and Pueblo are funding the fens research. Although the Whitney project is not directly tied to the fen project, if the research efforts are successful, they could help Aurora and Colorado Springs secure a permit approval for the reservoir — and maybe alter the fate of an ecosystem.
If you’ve walked through Colorado’s high country, chances are you’ve walked by a fen, which are among the state’s most biodiverse and fragile environments. To protect fens, the U.S. Fish and Wildlife Service and the Environmental Protection Agency drafted a “fen policy” in 1996. The policy, amended in 1999, determined that fens are irreplaceable resources because their soils take so long to regenerate. “On-site or in-kind replacement of peatlands is not possible,” the policy reads.
Inside the Fish and Wildlife Service, however, a different interpretation emerged. “Irreplaceable” became “unmitigable,” making it difficult or impossible to secure approval for any project that would severely impact fens.
Although Johnson is in favor of fen conservation, the Fish and Wildlife Service’s “unmitigable” interpretation bothered him. Not only was that status not supported by the fen policy itself, he believes saying “no” all the time is not in the best interest of fens.
“My fear is that if we don’t have the means of mitigating our impacts, we’ll just impact them,” he said.
Eventually, Johnson believes, conservationists will have to make some concessions to development. But by researching better mitigation techniques, he hopes he can help preserve fens in the long run.
An organ transplant
For water utilities, fens have been particularly troublesome. Fens like to form in high-alpine valleys, the places best suited for dams and water reservoirs that take water from rivers mostly on the Western Slope and pump it over the mountains to supply the Front Range’s growing population.
But the fen policy has stymied many of the utilities’ plans to develop new water projects. Those defeats helped spur Front Range utilities to start researching new mitigation strategies that would help them comply with environmental regulations — and get around the fen policy.
“They wanted to figure out how to do this right so they could actually permit their projects,” Johnson said.
Through the fen-research project, Aurora and Pueblo saw an opportunity to address the fen policy’s requirement that a project offset unavoidable impacts to a fen by restoring an equivalent amount of fen elsewhere.
Since the fen project began 16 years ago, Aurora and Pueblo have invested $300,000 and $81,500 in the research, respectively. More recently, other funders have joined the effort, including Denver Water, Colorado Springs Utilities at about $10,000 each and the Colorado Water Conservation Board ($100,000).
After a number of fits and starts, Johnson three years ago settled on a design for the research that would test whether it’s ecologically possible to transplant fen soils from one location to another. First, Johnson restored the original groundwater spring at the old Hayden Ranch property. Then, he and a team of helpers removed blocks of soil from another degraded fen site and reassembled them, like an organ transplant, at the “receiver” site, where the restored spring now flows through veinlike cobble bars and sandbars, feeding the transplanted fen.
It’s still too early to know whether the project could eventually serve as a fen-mitigation strategy for a new reservoir, but Johnson is optimistic about the results thus far. In 2017, after just one growing season, he was shocked to discover 67 different plant species growing at the transplanted fen site — compared with just 10 at the donor site. He was thrilled by the news. The data showed that the transplanted fen ecosystem is thriving.
That’s good news for utilities such as Aurora, too.
A week after Johnson visited the Rocky Mountain Fen Project site, Kathy Kitzmann gave a tour of the wetland-filled valley formed by Homestake Creek where Aurora and Colorado Springs are planning to build Whitney Reservoir.
Kitzmann, a water resources principal for Aurora Water, drove down the bumpy, snow-covered road that winds along the valley bottom, pointing to the two creeks that would — along with Homestake Creek and the Eagle River, near Camp Hale — help fill the reservoir. A pump station would send the water upvalley to the existing Homestake Reservoir and then through another series of tunnels to the Front Range.
In the lower part of the valley, Kitzmann stopped at the first of four potential reservoir sites — ranging in size from 6,000 acre-feet to 20,000 acre-feet — that the utilities have identified for the project and the wetlands it would inundate.
“You can sort of see why it wouldn’t be the best, just given the vastness of the wetlands,” Kitzmann said.
Farther along, the valley becomes more canyonlike, with higher rocky walls and fewer wetlands — probably offering a better reservoir site, said Kitzmann, although the permitting agencies won’t know for sure until they complete their initial feasibility studies.
In June, Aurora and Colorado Springs submitted a permit application to the U.S. Forest Service to perform exploratory drilling and other mapping and surveying work, but the agency has not yet approved the permit.
Potential fen impacts are just one of several environmental hurdles facing the project. One of the Whitney alternatives would encroach on the Holy Cross Wilderness. Aurora and Colorado Springs have proposed moving the wilderness boundary, if necessary, to accommodate the reservoir.
It’s also likely that the wetlands in the Homestake Valley contain fens, but until the utilities conduct wetland studies around the proposed reservoir sites next summer, the scope of the impacts remains uncertain.
Environmental groups including Colorado Headwaters, a nonprofit, oppose the Whitney Reservoir project, arguing that it would destroy one of the state’s most valuable wetlands, as well as an important habitat for wildlife and rare native plants.
In the meantime, Aurora is hopeful that Johnson’s research might one day help solve some of the environmental problems around new water development. “We are excited about proving that you can restore and rehabilitate fens,” Kitzmann said.
But is a transplanted fen as good as not touching one in the first place?
A Fish and Wildlife Service spokesperson said fens are still designated a “Resource Category 1,” which means that the appropriate type of mitigation is avoidance, or “no loss.”
White River National Forest supervisor Scott Fitzwilliams echoed the spokesperson’s statement, noting that land managers place a high emphasis on protection for fens: “It’s really hard to replace a wetland in these high elevations.”
Johnson, asked whether he was worried that his research into fen mitigation might end up facilitating the kinds of projects that are most damaging to fens. He sighed. “I’m sensitive to that,” he said.
But like it or not, Johnson believes that more impacts to fens are inevitable. As Colorado’s population grows, water utilities will have to build new reservoirs, the state will need new roads and ski resorts will want to expand.
“I can’t argue with whether they should get built,” he said. “I’m just a wetlands guy.”

The Homestake Project is a trans-mountain raw water collection, storage, and delivery system co-owned and operated by the cities of Colorado Springs and Aurora, Colo.
The Homestake Arkansas River Diversion (ARD), between Granite and Buena Vista, Colo., was constructed in 1964 as the original intake for the Otero Pump Station. Water is now primarily withdrawn from Twin Lakes, however the ARD remains an alternate point of diversion. The ARD has deteriorated and requires repair. The ARD was not originally designed as a navigable facility.
Colorado Parks and Wildlife (CPW) manages the Arkansas Headwaters Recreation Area (AHRA) which includes the site of the ARD. CPW expressed interest in partnering with Springs Utilities on a rehabilitation project to include a boat chute for downstream navigation as this location is currently considered the only non-navigable reach of the Arkansas River between Leadville and Canon City, Colo.
The Upper Arkansas River is both one of the most heavily used rivers in the United States for whitewater recreation and is a Gold Medal Trout Fishery. The river is managed to support multiple objectives including water supply and delivery and outdoor recreation.
The cities of Aurora and Colorado Springs are constructing a rehabilitation project that will replace the intake and diversion, provide a boat chute for downstream navigation, and provide upstream fish passage for spawning of brown and rainbow trout. The project also included improving river safety for recreational users and providing whitewater boat portage. User safety was an extremely important design consideration.
A physical model was constructed to test and refine hydraulic elements to optimize performance, maximize user safety and meet design guidelines for recreational whitewater for all three components: boat chute, fish passage and the new intake structure.
The $9 million construction cost of the project is being jointly funded by the cities of Aurora and Colorado Springs. $1.2 million in grants is coming from Colorado Parks and Wildlife and the Colorado Water Conservation Board through grant funding to support the Colorado Water Plan (Water Supply and Demand Gap and Environmental and Recreation Grant Programs). The Pueblo Board of Waterworks is donating the easements necessary to construct and maintain the diversion.
Here’s a report from Jason Blevins writing for The Colorado Sun:
But just below the former riverside mining camp of Granite, where a dilapidated dam built in 1964 has long blemished the Arkansas River’s beauty, rebar jutted from concrete blocks, preventing raft passage and spawning trout battled the steep wall of blasted rocks to reach upstream pools.
“Not a lot of thought went into recreation or fish when this dam was built,” said Ronald Sanchez, an engineer with Colorado Springs Utilities.
A lot of thought is going into fish and recreation now, as water managers in Colorado Springs and Aurora join the Colorado Water Conservation Board, the Pueblo Board of Water Works, Colorado Parks and Wildlife and the Arkansas Headwaters Recreation Area in rebuilding the diversion that directs water to the Front Range.
The $9.1 million project will make the entire river from Leadville to Cañon City navigable for rafts for the first time in at least 55 years.
It’s part of the vast Colorado Springs- and Aurora-owned Homestake Project that brings Eagle River Basin water from the Holy Cross Wilderness to the Arkansas River Basin, through the Homestake, Turquoise and Twin Lakes reservoirs for delivery to the Front Range cities.
The cities started construction of the Arkansas River diversion in July 2018, creating three distinct channels below a rebuilt intake that serves as a backup water diversion to the Otero Pump station downstream of Twin Lakes Dam. Before the Twin Lakes Dam was built in the late 1970s, the diversion was the original intake that collected and directed water to the Otero Pump station for delivery to Aurora and Colorado Springs.
One channel is a fish ladder for spawning brown and rainbow trout. Another channel is a spillway to accommodate flood-level flows like the ones that swelled the Arkansas River this spring. And a third is a series of six drops allowing rafts safe passage.
The project marks a new era of collaboration between the diverse interests on the Arkansas River between Leadville and Cañon City, one of the most recreated stretches of river in the U.S.
“For me the coolest thing about it is that you have these large water utilities in Colorado going above and beyond to do the right thing for the next 50 years,” said Salida-based whitewater park engineer Mike Harvey.
Ten years ago, Harvey helped the Arkansas Headwaters Recreation Area craft a report urging Aurora and Colorado Springs to consider recreation and fish when it came time to rebuild the Granite Dam diversion…
The Arkansas River accounts for more than $74 million of the $177 million in economic impact created by commercial rafting in Colorado. The 102 miles of river in the Upper Arkansas River Valley also ranks among the 322 miles of Colorado waterways that qualify as Gold Medal Fisheries that can yield a dozen large trout per acre. It also supplies a large percentage of water to Colorado Springs and Aurora via the 66-inch pipeline that runs from the Otero Pump Station.
Rebecca Mitchell, the executive director of the Colorado Water Conservation Board, said the project exemplifies the collaboration of the Colorado Water Plan, which gathered perspectives from all types of water users in the state to create a policy roadmap for future water planning across the state.
Colorado Parks and Wildlife and the conservation board provided $1.2 million in funding through Colorado Water Plan grant programs.
Local officials say damming a creek between Leadville and Minturn — and routing water normally flowing into the Colorado River — is necessary to sate the future thirsts of a city growing on land where water is scarce.
Aurora Water and Colorado Springs Utilities recently applied together for a permit to drill underground near the creek and test where a large Whitney Reservoir would be best situated.
For the dam, the utilities are eyeing four possible locations about six miles southwest of Red Cliff.
But damming Homestake Creek would also require moving the boundary of the Holy Cross Wilderness, affecting ancient, pristine wetlands.
Greg Baker, Aurora Water’s manager of public relations, said the Whitney Reservoir could be built in 25 years if key steps such as test drilling on Forest Service land are approved.
Baker said it’s another creative step to make sure that Aurora doesn’t go dry.
“You don’t leave anything on the table when you’re in Colorado, because most of the water has been appropriated in river basins,” he said.
Baker said the reservoir could eventually hold anywhere from 9,000 acre-feet to 19,000 acre-feet of water. The water would then be pumped near Leadville and travel to the Front Range through tunnels to the South Platte River basin.
Currently, only Aurora and Colorado Springs would benefit, Baker said.
The project is another alliance between Aurora Water and Colorado Springs Utilities. The two cities — the state’s largest behind Denver — are both growing quickly. Baker said the new reservoir could help ensure the taps keep flowing, especially in an era with snowpack decreases that imperil creeks and rivers.
For two decades, hydrogeologist Lee Pivonka has monitored toxic waste at and around the Superfund site for Colorado Department of Public Health and Environment.
He’s one of the most prominent voices in the state calling for more scrutiny of the site.
Pivonka told Sentinel Colorado that pollution testing wells — not private wells for drinking — north of the Superfund site boundary were found to have unacceptably high levels of contamination as far back as 1995, when city councillors gave Murphy Creek the green light. Chemicals in many wells have never returned to acceptable levels, he said.
In 2002, EPA became concerned with a chemical called 1,4 dioxane. The stuff is widely found in trace amounts in household products such as detergents and shampoos. It is probably a carcinogen if ingested in high-enough concentrations through drinking contaminated water, the EPA says, but most people will not be exposed to it that way in their lifetimes. The New York state legislature recently passed a ban on products with more than trace amounts of 1,4 dioxane. The bill is pending Governor Andrew Cuomo’s signature.
For Murphy Creek golfers teeing off and residents, the danger is low, the WSDs said.
Further to their point, it’s unheard of for golfers to drink the creek water. The course itself, like the Murphy Creek neighborhood, is irrigated with clean City of Aurora water.
But scientists have also monitored 1,4 dioxane because it moves quickly in water. They believe that tracking the chemical could indicate other toxic waste following it.
As the state government’s lead researcher for the site, Pivonka has watched for the last 20 years and conducted more evidence about the leaking waste. In 2015, he co-authored a lengthy analysis to try and spur new fixes.
That paper mapped underground chemicals spreading down the Murphy Creek wash past East Jewell Avenue, below the edge of the Murphy Creek Golf Course and the community itself.
The paper estimated that 425.6 million gallons of contaminated water has leaked from the site in the plume, according to data from about a decade earlier. It’s a worrisome prospect for homes near the plume and on well water, such as the Raders’.
In the paper, Pivonka recommended that the EPA and the polluters try something new. The EPA recently heeded his suggestion that EPA stop injecting huge amounts of treated water north of the site.
Water was treated for various chemicals except for 1,4 dioxane, and pumped north of the site until the early 2000s. The WSDs then began treating water for 1,4 dioxane and injecting that north of the site until October 2018.
But while Pivonka and others conduct their own studies, the EPA and polluters have relied on separate studies and often come to separate conclusions. The debate over how and when the pollution has spread is rooted in a parallel universe of research at the EPA.
That agency’s conclusions, however, are often based on research commissioned by the WSDs.
The WSDs told Sentinel Colorado that, based on their information and EPA conclusions, the plan for containing the waste is currently protecting the public.
Karen Crummy of public relations firm BluePrint Strategies responded to Sentinel Colorado as the WSD spokeswoman. Crummy is routinely a spokesperson for oil and gas industry political causes.
The group believes the plume exists but is shrinking, pointing to data from a commissioned 2018 study indicating decreases in 1,4 dioxane levels at various locations north of the site.
Dave Wilmoth, a City and County of Denver official and environmental engineer, recently toured the site. He is a site expert representing Denver in the WSD group…
Wilmoth said the plan in place is working effectively. The contamination north of the site is little more than trace amounts of 1,4 dioxane, he said, blaming the outdated practice of dumping water contaminated with the stuff beyond the site’s northern barrier wall.
“No regulations,” he said of 1,4 dioxane. “No one knew.”
But that was almost two decades ago.
EPA spokesperson Rich Mylott said the containment plan is “working effectively to prevent off-site exposure to contaminants.”
However, the EPA is not sure that shallow and deep groundwater is safe from contamination, and directed the WSDs to commission their own studies of possible contamination. Two years ago, the agency declined to say in a multi-year study and report whether the site was adequately protecting the public.
The possible contamination of aquifers is a huge concern for Pivonka and Rader.
Two aquifers, the Denver and Dawson, overlap just north of the site where the plume is contaminating surface waters. The Dawson formation lies above the Denver, a 3,000-square mile table of water, separated by a leaky barrier of earth.
Both are important sources of drinking water for the dry Front Range. Serious contamination would threaten a key resource that scientists believe will become more scarce in the decades to come.
The EPA also acknowledges the existence of the surface water plume in the review but said the WSDs need to conduct more studies before it creates a plan.
In the years since, the polluters’ group has been doing just that. They say they are working to get the additional data EPA needs to again find the site remedy “effective and protective.”
The WSDs said it could also consider new solutions, such as drilling new monitoring wells — in addition to the 500 that already exist — changing how they monitor the groundwater, and studying the impact of injecting water north of the site.
The prospect of polluters running their own studies for the EPA worries Bonnie Rader, who is now chairing the site Community Advisory Group.
The group has long received funds from the EPA to hire out its own, independent contractors to study the pollution.
She doesn’t trust the polluters nor the EPA to reach their own conclusions.
The CAG consultant, McGinnis and Associates, reviewed a polluter-funded study of the site in 2013. Rader sent the review to a lead scientist at the EPA, who analyzed the study line-by-line, finding inaccuracies and omissions. The errors include misrepresenting levels of 1,4 dioxane in test wells.
McGinnis also believes the plume is growing, not shrinking.
It’s emblematic of an information gap that strains relationships between the various consultants and agencies.
Different studies come to different conclusions, frustrating all parties involved. Technical disagreements can turn sharky in tone.
Generally, the EPA and polluters believe they should stay the course, while CDPHE and the citizen-hired McGinnis and Associates think more should be done to contain and clean up the waste.
The EPA and polluters can press ahead with their own plans, but area residents and their consultants are extremely concerned about the leaking waste and continue to pressure them.
In the 2017 review, EPA staffers conducted interviews with locals. “All private citizens interviewed are concerned about groundwater contamination and the use of private residential wells,” the report says.
The gulf between the parties has also widened because of little trust and bad communication.
Four years after his paper’s findings, Pivonka said the EPA and polluters “have not been receptive to the recommendations, and continue the same approach to the site.”
Rader is disillusioned with the WSDs and their studies. She said she’s been hearing the same old reassurances for the last 30 years while the waste spreads north, closer to her home.
The polluters’ trust disagrees with the notion that they have not listened to residents, Crummy said. She said WSD representatives regularly attend meetings with locals.
The mass of evidence, varying conclusions and convictions on all sides leaves residents with vague concerns at best but nightmares at worse about the situation actually harming people…
…the mere possibility of pollution has encouraged new, suburban residents to forge an alliance with Rader and other environmental crusaders. While a subdivision lies close to the spreading plume, they are vehemently opposed to a new plan to house thousands of new residents on its doorstep, for reasons of their own…
The Superfund site and its leaking waste was not news to [Nicole] Johnston, who represents the eastern frontier region of the city. She actually became involved in the CAG herself before running for city council, and was interviewed in the EPA’s 2017 review study that downgraded the protectiveness of the site.
She said that 1,4 dioxane may not even be her biggest concern, compared to other chemicals dumped in the Superfund site.
“They put some really, really bad things in there,” she said. “Those other, really bad chemicals could be right behind it.”
Johnston met with Rep. Jason Crow that April afternoon when he visited the plume.
She said that, although the plume concerns her very much, the possibility of two injection wells about five miles from the site could dramatically change the area’s geology.
The wells, proposed by Wyoming- and Denver-based Expedition Water Solutions, would flush mostly saltwater and other by-products from oil and gas extraction more than 10,000 feet below the surface.
Injection wells are known to cause earthquakes in some circumstances, according to the United States Geological Survey.
But the science that the Superfund site geology could be disrupted is far from certain.
Zach Neal, a spokesperson for EWS, said the proposed location was the only possible place for the injection wells because of county zoning restrictions.
He added that the wells would be safely built and regulated. EWS would inject the waste far deeper below the surface than the Denver and Dawson aquifers.
Arapahoe County officials told Sentinel Colorado that staff are still reviewing the applications, and the state government agency charged with reviewing proposals has not taken action since EWS filed its paperwork in February.
Arapahoe County Commissioner Jeff Baker represents the Superfund site area and the residents that live in the unincorporated county. He said he’s also worried about the injection well permits and will be scrutinizing them, he said.
But Baker said he is also open to considering whether the solution to keeping residents safe from the Lowry Landfill should still be trying to contain the waste. He’s open to discussing a plan to clean up the waste, once and for all.
It’s an idea that Bonnie Rader has clamored for during the last 50 years.
Here’s the release from Aurora Water (Greg Baker):
Water rights purchase provides environmental benefit
Aurora Water has finalized the purchase of water rights associated with the London Mine, located near Alma, in Park County. 1,411 acre feet (af) of water has been acquired at price of $22,000 per af, with additional costs of $2 million for an option to acquire additional water rights as they are developed and $1M for an easement. An acre foot of water is 325,851 gallons, enough water to serve 2.5 households on average. The seller of the rights is MineWater Finance, LLC and No Name Investors, both Colorado companies. The total value of this initial purchase is $34,042,000. The sellers are confident that the source of the rights could ultimately result in additional water that Aurora has the exclusive option to purchase for $21,500 per acre foot.
The source of this water is from a basin that is recharged from snowmelt on London Mountain. A geologic fault contains the water underground and prevents it from discharging into South Mosquito Creek, a tributary of the South Platte River. This water is pumped from the basin to a water tunnel in the London Mine and from there, discharged into South Mosquito Creek, which is upstream of Aurora’s Spinney Mountain Reservoir. Since this water is not naturally connected to the streams, it is decreed under Colorado Water Law as non-tributary. This has special meaning as this water is fully reusable and can be recaptured utilizing Aurora’s Prairie Waters system, a potable reuse system.
Aurora Water has been a national leader in water efficiency, including an acclaimed Prairie Waters water reuse system, and a nationally recognized water conservation program. Water acquisition is still necessary to meet future demands.
“Looking for new water supplies in the arid west requires innovative thinking,” said Marshall Brown, Director for Aurora Water. “This is a supply that historically has not been tapped by water providers, but the easier supplies are gone.”
The environmentally positive aspects of purchase have resulted in praise from organizations such as the Boulder-based Water Resource Advocates (WRA).
“New water supplies in Colorado are extremely limited and, at the same time, nearly 2,000 miles of streams in Colorado are polluted by mines,” Laura Belanger, Water Resources and Environmental Engineer with WRA stated. “We commend Aurora Water for taking a leadership role in finding this inventive and environmentally beneficial solution to meeting its customers’ water needs.”
Aurora Water completed substantial due diligence prior to this initial closing. Additional water rights under the option provision will be purchased as they are adjudicated and decreed through Colorado’s Water Courts.
Aurora Water is only purchasing the water rights. MineWater will continue to be responsible for the mine property, wells and associated permits. Questions regarding the mining operations, including the permits, should be directed to the MineWater contact listed above.

From 1874 until the 1940s, the London Mine was one of the top-producing gold mines in the state. It also produced lead, silver and zinc. In 1991 the mine eventually closed, but a fault within the mountain created a natural reservoir, one that fills with snowmelt.
In the nearly three decades since the mine has been closed, the state health department and U.S. Environmental Protection Agency have had their eye on the mine and its previous owners. In 2009, 2011 and 2013 CDPHE cited the mine for violating the discharge permit. A treatment plan for the mine was created, but it failed. And in 2016 CDPHE slapped the owner previous to MineWater with a $1.1 million fine.
Water officials and MineWater have studied the water, and will continue to do so, to make sure it’s a safe source.
MineWater, which has completely reworked the plumbing of the mine, will still continue its operations and hold all mine permits. Aurora water is only purchasing the water rights.
