Telluride: Pandora raw water and treated water project is moving along nicely

Bridal Veil Falls

From The Telluride Daily Planet (Collin McRann):

The Pandora water treatment project at the east end of the valley is on schedule and should be complete by this fall, ending more than three years of construction.

The project, which fired up in 2011, has been in the works for more than 20 years, and it will pipe water from Upper Bridal Veil Basin to a new treatment facility at the east end of the box canyon. And while there have been many hurdles, including engineering challenges and budgetary issues, the project should be complete by October and stay within the town’s 2014 budget, according to Telluride Public Works Director Paul Ruud.

“We keep making progress on the building and the water plant itself,” Rudd said. “The building is almost completed. We’re just outfitting the internals. There are aspects of the project that are done. We’ve tied in both the raw waterline coming in from Bridal Veil [Falls] and the treated line that’s going towards town, into the plant.”

Ruud said crews are also working on a physical water diversion out of Bridal Veil Creek as well as a number of other components involved with the diversion. If things go as planned, the plant will go online in early October.

“We haven’t really had any issues,” Ruud said. “We did have fairly substantial soil stabilization right at the treatment plant. That ended up being quite a substantial undertaking. But as of right now we are within the approved budget for this year and we expect the project will be completed with our existing budget.”

The facility will also contain a micro-hydro component that is expected to be operational when the plant goes live, which will boost the town’s generation of renewable energy. But the main purpose of the plant is to boost the town’s water capacity. Telluride’s current system, which relies primarily on the Mill Creek Water Plant, has been strained by high demand and other issues in recent years.

Rudd said construction has been making good progress this summer. With the good weather there have been a lot of people in the area going up to Bridal Veil Falls. But disturbances from construction are nearing an end.

Lamar: New water line should deliver higher quality water

July 14, 2014

pipeline

From The Pueblo Chieftain (Chris Woodka):

Lamar has completed a new water line that will allow it to deliver cleaner water to customers.

“We’re meeting our water quality goals by using our southern wells,” Josh Cichocki, Lamar water superintendent, told the Arkansas Basin Roundtable on Wednesday. “Not only did the project help us with water quality, but it helped with efficiency as well.”

The roundtable approved a $200,000 state grant last year that went toward the $2 million project. Other sources of funding were a $785,000 loan from the Colorado Water Conservation Board and a $985,000 grant from the Department of Local Affairs.

The project installed 6.5 miles of pipeline in a portion of the well field where pipes had become badly corroded. Completed during a drought, there were no major construction issues, Cichocki said.

“Our biggest obstacles were wind and tumbleweeds,” he laughed.

He explained that the southern wells used in the Lamar water system have the lowest measurement of total dissolved solids. That means the water does not require as much treatment to bring up to drinking water quality standards.

Lamar has gained between 180-250 acre-feet (58.6 million-81.4 million gallons) per year because of the improvements.

Rifle: Bids for new water treatment plant blow budget

The water treatment process

From the Rifle Citizen Telegram (Mike McKibbin):

Rather than wait up to another year and risk even higher costs, Rifle City Council unanimously rejected two bids on a new $25 million water treatment plant and decided to proceed under a “sole source” approach.

At a special June 25 meeting, the council also approved nearly $150,000 in project expenses, an application for a $2 million state grant to help purchase filters and equipment for the plant and the return of a $600,000 grant that was to help build a new main waterline connection to South Rifle.

The action came after two bids for the project came in $8 million to $11 million higher than the city engineer’s estimate and the funds available to build the plant. Alder Construction, located in Salt Lake City, Utah, submitted a base bid of $33.1 million and PCL Construction, located in Phoenix, Ariz., with an office in Glenwood Springs, submitted a base bid of approximately $36.5 million.

The city received a $25 million low-interest loan from the Colorado Water Resources and Power Development Authority, to help pay for the plant. Two years ago, Rifle voters approved a 3/4 cent sales tax increase to help repay the loan.

Mayor Randy Winkler said the city had underestimated the cost of the new plant.

“All building costs seem to have gone up greatly just in the last year,” he said. “So we were forced to really take a hard look at this project.”

The project was originally designed to include improvements to the city’s raw water pump station, a new 24-inch raw water pipeline to the new 40,000-square-foot plant, a radio tower at the existing Graham Mesa water plant for remote data transmission of information about the city’s water system to the pump station and then by cable to the new plant, and connections to water transmission and main lines.

City officials have said the Graham Mesa plant is aging, undersized to serve projected population growth and unable to meet possible tougher federal water quality standards in the future. Construction work was expected to last up to two years.

Union Pacific plans treatment plant for discharge mitigation at the West Portal of the Moffat Tunnel #ColoradoRiver

July 2, 2014

westportalmoffattunnel

From the Sky-Hi Daily News (Hank Shell):

The Union Pacific Railroad announced on June 19 that it plans to construct a water treatment facility that will remove fine particulates and metals discharged in flows from the west portal.

As part of its discharge permit, Union Pacific must meet preset effluent limitations by April 30, 2017. The new treatment plant will help Union Pacific reach compliance with those limitations.

“It’s a victory,” said Mike Wageck, president of the East Grand Water Quality Board. “It’s definitely a victory for the river, if they’re going to be removing that coal dust that’s getting in there and removing those metals.”

The way the tunnel is bored, ground water flows from seepages inside the tunnel, picking up coal dust left by passing trains and heavy metals leached from the railroad ballast and exposed rock.

“This isn’t much different than a mineral mine,” said Kirk Klancke, East Grand Water Quality Board member. “If you just put a hole in the ground and have water leeching out, it’s going to carry the heavy metals you’ve exposed that have been buried for millennia.”

The way the Moffat Tunnel is pitched, water flows from both portals of the tunnel. To the east, water flows through a sedimentation pond before it’s discharged into South Boulder Creek. But to the west, water flows untreated into the Fraser. In 2013, average daily flows from the west portal were 171 gallons per minute, according to an implementation schedule sent from Union Pacific to the Colorado Department of Public Health and Environment.

The sediment in this discharge increases turbidity, or cloudiness, in the Fraser River…

Slag, a by-product of metal processing found in railroad ballast, leeches copper, lead, mercury and arsenic, among other elements, into the discharge and ultimately the river, according to the implementation schedule.

“Basically, from 2007 to today, we’ve been reviewing various ways we could treat the water coming out, primarily the water when it comes out of the tunnel,” said Mark Davis, a spokesman for Union Pacific.

Union Pacific examined a number of options for reaching compliance with effluent levels in the discharge, including diverting the water to publicly-owned treatment works in Winter Park, though the town ultimately decided that it would not benefit from receiving the water, pretreated or not…

Davis said he wasn’t sure when construction on the facility would begin or how much it would cost, though the state requires that Union Pacific have something in place by its compliance date of April 30, 2017.

Editor’s note:This is the first installment of a three-part series examining the past, present and future of Clear Creek…

Gold

There’s a monument in Idaho Springs hidden away in the parking lot of the former middle school. The giant boulder pays tribute to George Jackson, an adventurer and fortune hunter, who discovered gold in Clear Creek 155 years ago.

According to Don Allan, vice president of the Idaho Springs Historical Society, Jackson’s curiosity to follow the creek west into the mountains with only a couple of dogs by his side led to the country’s second largest gold rush.

Like a row of dominoes, Jackson’s discovery led to an onslaught of pioneers and ultimately in 1876 to the formation of a state.

“(Jackson) decided to go over and take a look down at the crick, and his curiosity brought him here to the confluence of Chicago Creek and Clear Creek,” Allan said. “When I talk with people about our community and how we got here, it was because of one man’s very good curiosity and a piece of gold.”

Jackson discovered gold in January, and by June, more than 400 people had settled in the area.

Natural hot springs drew more people into the area. Allan said in the Idaho Springs museum’s photography collection, there’s a photo of more than 50 employees standing in front of the hot springs.

“Once the stream was panned out, they panned all the gold out of the crick. Then they had to dig and make mining mills,” Allan said. “And this crick was integral to the milling of all the gold and silver in this area.”

The creek was used to support the mining industry such as the Mixel Dam in Idaho Springs, which was formed to help power mining mills and to create electricity. In 1864, silver was discovered to be the main mining mineral in Georgetown, and by 1877, the railroad reached Idaho Springs.

According to “A History of Clear Creek County,” the area at one point had 48 different towns with names such as Red Elephant, Freeland and Hill City. It is estimated that several thousand mines crisscrossed the mountains around Clear Creek as people sought their fortunes first along its banks and then in its mountains.

Those unlucky in gold sometimes found their way into the county’s second largest industry: logging. Early photos of the surrounding hillsides show them stripped of trees. But in time, the mining and logging industry waned, the frenzy slowed and the towns disappeared until there were only four municipalities left: Idaho Springs, Georgetown, Empire and Silver Plume. By World War II, the county’s mining industry has come almost to a complete halt.

But the stream once called Cannonball Creek, Vasquez Fork and lastly Clear Creek remained.

From The Pueblo Chieftain (Chris Woodka):

The Resurrection Mining Co. has filed its plan in water court to permanently replace flows to the Arkansas River water from its Yak Tunnel reclamation plant.

According to a court filing in May, the company plans to dedicate 10 shares of Twin Lakes water to flow down Lake Creek to replace the water it is capturing and cleaning at the Yak Tunnel plant and surge pond about 1 mile southeast of Leadville.

The water court application formalizes an arrangement that has been in place since Resurrection took over operation of the Yak Tunnel from ASARCO after a bankruptcy filing in 2005.

ASARCO began operating the Yak Tunnel plant in 1989 following federal court decisions that required mining companies to intercept and treat drainage from mine tunnels. Twin Lakes shares were leased until the company bought its own shares in 1994.

Depletions amounted to 3-7.7 acre-feet (1 million- 2.5 million gallons) annually from 2006-13. Replacement for those flows were replaced under a substitute water supply plan, an agreement administered by the state Division of Water Resources.

The tunnel, like others in the area, originally was drilled to dewater mines and increase productivity. However, the drainage includes heavy metals that diminish water quality and endanger wildlife. The surge pond captures water that escapes from tunnels and allows the water treatment plan The court filing assures that an operating plan is in place, regardless of how much water is needed in any given year to replace depletion.

“What dilutes it [selenium concentrations] is high flows, and we just haven’t had them for a while” — Randy Hayzlett

June 1, 2014

selenium
From The Pueblo Chieftain (Chris Woodka):

The state is looking at research in fields near Rocky Ford to determine if irrigation practices could improve Arkansas River water quality.

On Thursday, officials from Colorado and Kansas health agencies and researchers looked at how intercepting water from fields through irrigation drains could prevent deeper leaching of water and nitrates into the soil. That leaching action, when it reaches bedrock layers of shale, triggers suspended selenium releases that are harmful to wildlife, explained Tim Gates, a Colorado State University- Fort Collins researcher who has spent 15 years investigating Arkansas Valley irrigation systems.

“Excess irrigation percolates through to the shales and soils around them and the nitrates in the soil from excessive fertilization causes the selenium to dissolve out,” Gates said.

To a large degree, the increase of sprinkler systems and drip irrigation has reduced the amount of water applied to fields, meaning less water to percolate deeply in the soil.

But in fields still flood irrigated, drains could provide a means to reduce selenium buildup.

Many of the farms in the Lower Arkansas Valley have tile drains installed in the first part of the 1900s under federal programs as a way to reduce waterlogging.

A two-year study funded by the Colorado Department of Public Health and Environment is looking at how effectively those drains can prevent selenium concentration.

“What it’s looking at is whether there’s a better way to intercept and control it,” said Jim Valliant, a retired CSU Extension researcher who is working on the project. Valliant also represents Crowley County on the Lower Arkansas Valley Water Conservancy District board.

Part of the problem rests with state water law, he added.

“Farmers are told to use it or lose it, so it encourages over-irrigation,” Valliant said. “But I think younger farmers are more willing to adapt. I think we can work together to improve the quality of the water returning to the Arkansas River.”

Cutting down on fertilizer application, which releases nitrates, could also save farmers money, Valliant said.

The levels of selenium in the Arkansas River are exacerbated by higher base flows on Fountain Creek, along with storms on Fountain Creek and Wild Horse Creek in the Pueblo area. But return flows from irrigation also react with shale that lies on the surface and up to 40 feet below throughout the valley.

It also creates a problem for downstream users, because the selenium accumulates as water moves along the river.

“Lakin, Kan., is a small community of about 1,800, and we had to build a $6 million water treatment plant,” said Randy Hayzlett, who represents Kansas on the Arkansas River Compact Administration. “I think the problem is getting worse. What dilutes it is high flows, and we just haven’t had them for a while.”
