Colorado Water Officials Create First-Ever Regulations for ‘Forever Chemical’ PFAS

/in , /by /Colorado Public Radioby Sam Brasch

Colorado has its first policy to regulate so-called “forever chemicals.”

The state’s Water Quality Control Commission voted unanimously Tuesday to enact a policy to put new limits on per-and poly-fluoroalkyl substances, better known as PFAS. The class of chemicals is a common ingredient in everything from nonstick pans to foam used to smother flames from jet fuel.

A growing body of scientific evidence has linked the chemicals to a range of health problems, including cancer and pregnancy issues. Meanwhile, federal efforts to regulate the chemicals have lagged, leaving states to take action on their own.

Extreme Atmospheric Rivers: What will California’s Strongest Storms Look Like in a Warming Climate?

/in , , /by /WeatherWestby Daniel Swain

Atmospheric rivers (ARs)—long, sinuous corridors of water vapor in motion in the lower half of Earth’s atmosphere—are a key aspect of California’s cool-season climate. ARs are in many cases pretty unremarkable when they’re out over the open ocean, visible on satellite as a narrow ribbon of cloudiness and (usually) light precipitation. But when these moisture plumes attach themselves to wintertime low pressure systems and make landfall along the California coast, the consequences can be dramatic—prolonged heavy rain and mountain snow often result, along with sometimes powerful winds.

A proposed pipeline in Utah could divert approximately 86,000 acre feet of water annually from Lake Mead, but it will most likely not harm the overall water level in the reservoir.

Future Precipitation Increase from Very High Resolution Ensemble Downscaling of Extreme Atmospheric River Storms In California

/in , /by /Science Advancesby Xingying Huang, Daniel L. Swain, and Alex D. Hall

Precipitation extremes will likely intensify under climate change. However, much uncertainty surrounds intensification of high-magnitude events that are often inadequately resolved by global climate models. In this analysis, we develop a framework involving targeted dynamical downscaling of historical and future extreme precipitation events produced by a large ensemble of a global climate model.

The city received $4.565 million in state grant funding to expand its water reuse efforts, with most of the funds going toward its Pure Water Oceanside Project.

The city received the money from the Department of Water Resources through the state’s Integrated Regional Water Management Program. The program supports water reuse programs like Oceanside’s to increase the state’s water sustainability.
