Environmental agency found no evidence of widespread impacts

Staff Report

FRISCO — In a draft fracking study that was subject to a political tug-of-war even before it was released, the EPA found no evidence of “widespread, systemic” impacts to drinking water, but identified numerous weaknesses in the fracking process that could lead to contamination. Continue reading

Environment: New Clean Water Rule finalized, but the fighting is not over

Runoff and rainstorms have combined to keep flows high in the Blue River.

A new EPA rule aims to define which streams and rivers are protected under the Clean Water Act.

Big loopholes for industry, farms will continue to threaten water quality

Staff Report

FRISCO — After years of wrangling, the EPA has finalized a new rule intended to define which streams are covered under the Clean Water Act. The debate goes back more than a decade to a pair of court rulings that called into question whether smaller tributaries and seasonal streams are subject to federal regulations.

Yesterday’s announcement probably won’t end the fighting — Republicans in Congress have launched a bitter attack on the rule at the behest of big polluters like industrial farms and factories, and some national conservation groups like the Waterkeeper Alliance say the new rule is too weak, and rolls back protection for some streams that were previously covered.

Study shows link between air, water pollution

This Meadow Creek, a wild, free-flowing stream that starts in the Eagles Nest Wilderness Area and ends up flowing right past our house before its confluence with Dillon Reservoir, where it's wild no more.

Atmospheric emissions of hormone-disrupting chemicals found to pollute rivers and streams.

Hormone-disrupting toxins in Missouri streams traced to factory emissions

Staff Report

FRISCO — Scientists say atmospheric releases of hormone-disrupting chemicals may be a big source of of pollution in streams and lakes. After studying water quality near industrial sites permitted to release toxic chemicals into the air, the researchers said they found unexpectedly high levels of BPA in water around those factories.

“This finding suggests that atmospheric BPA releases may contaminate local surface water, leading to greater exposure of humans or wildlife,” said Don Tillitt, adjunct professor of biological sciences at MU, and biochemistry and physiology branch chief with the U.S. Geological Survey’s Columbia Environmental Research Center.

Anglers invited to join citizen science effort

TroutBlitz helps conservation and restoration efforts

Staff Report

FRISCO — It’s not always easy to gather good scientific data, especially in an era when political ideology drives policy, resulting in budget cuts that hamper government agencies.

That’s where citizen science can help, and Trout Unlimited wants anglers around the country to help record evidence of their trout catches both photographically and via mapping coordinates with the relaunch of TroutBlitz.

TU’s science team uses the data collected from anglers to learn more about native trout water, non-native trout proliferation and the health of entire watersheds. Continue reading

Nevada Supreme Court rejects Las Vegas water grap

Pipeline dreams stumble at Nevada Supreme Court.

Ruling marks another win for activist network opposing the massive groundwater pumping and pipeline plan

Staff Report

FRISCO — A bid by Las Vegas to drain groundwater from distant valleys took another hit this week, as the Nevada Supreme Court blocked the latest legal maneuver by the Southern Nevada Water Authority and the Nevada State Engineer, who petitioned the court for writs of mandamus.

The ruling is a win for critics of the SNWA pipeline project, including White Pine County, the Great Basin Water Network and local Native American tribes, who say the plan will dry up springs and groundwater needed by local communities, as well as wildlife that relies on scarce sources of water in central and eastern Nevada.

Gotta love that Colorado River. Want to help save it? Conserve! @bberwyn photo.

By Bob Berwyn

FRISCO — Colorado’s creeping water crisis isn’t as dramatic as a wildfire or a flood, but its consequences could be just as severe. State and federal water experts say the state will see a huge gap between supply and demand within a few decades, and possibly sooner if regional drought continues. Continue reading

Environment: UK study shows how heavy metal pollution alters genetics of trout populations

Some trout populations in Colorado have been affected by toxic heavy metal pollution from abandoned mines.

Historic UK mining contamination has cut genetic diversity of brown trout

Staff Report

FRISCO — In a study that has implications for Colorado rivers and fish, scientists in the UK have shown that heavy metal pollution from mining has dramatically reduced  genetic diversity of brown trout.

The University of Exeter researchers say their findings show that human activity can alter the genetic patterns of wild populations — an important issue in modern conservation. Continue reading
