La Niña conditions were observed in the Pacific Ocean last month, and there is a 75% chance the weather pattern will persist through the winter, forecasters with the National Oceanic and Atmospheric Administration said.
Coal miners, stone quarrying companies, and other businesses are rushing to lock down any exemptions to federal water jurisdiction for at least five years, under changes the Trump administration recently made to the nation’s water rule.
Six states in the U.S. West that rely on the Colorado River to sustain cities and farms rebuked a plan to build an underground pipeline that would transport billions of gallons of water through the desert to southwest Utah.
In a joint letter Tuesday, water officials from Arizona, California, Colorado, Nevada, New Mexico and Wyoming urged the U.S. government to halt the approval process for the project, which would bring water 140 miles (225 km) from Lake Powell in northern Arizona to the growing area surrounding St. George, Utah.
Beyond all the health-related impacts of the coronavirus pandemic — masks, social distancing, work from home scheduling, etc. — there have been some ripple effects to the daily operations and related employment conditions for water-treatment personnel. This synopsis of experiences provides perspective and outlines some opportunities and approaches for water-industry professionals to adopt if they have not already done so as part of the post-COVID ‘new normal’.
The San Francisco Bay-Delta is literally threatened from all sides: rising sea levels from the ocean, disruptions to sediment supply from upstream, and within the Bay-Delta itself, development and other land use changes have left only a tiny fraction (5%) of marshland untouched.
After an extended weekend of wildfires, part of an early fire season that has already seen a record 2 million acres burned and Death Valley-like temperatures smothering the San Fernando Valley, Californians would be right to wonder whether we are living in a hellscape. We are not, it’s safe to say. But we are living in the future that climate scientists have been trying to warn us about for years now.
In the next five years, the world has nearly a 1-in-4 chance of experiencing a year that’s hot enough to put the global temperature at 2.7 degrees (1.5 degrees Celsius) above pre-industrial times, according to a new science update released Wednesday by the U.N., World Meteorological Organization and other global science groups.
The CZU Lightning Complex Fire’s threat to water quality in Santa Cruz came into sharper focus Tuesday as a Cal Fire emergency watershed response team neared completion of a damage study.
The most pressing risk is debris that could clog the San Lorenzo River near River Street and Highway 1 where water enters the city’s system, said Santa Cruz Water Director Rosemary Menard. The San Lorenzo River is the city’s largest water source. It represents about 45% of the water supply.
California’s mega-drought officially ended three years ago but may have turned the Creek Fire into a monster. By killing millions of trees in the Sierra National Forest, the historic drought that ended in 2017 left an incendiary supply of dry fuel that appears to have intensified the fire that’s ravaged more than 140,000 acres in the southern Sierra Nevada, wildfire scientists and forestry experts said Tuesday.
North Carolina, the EPA, and an international standards organization want to use a method for detecting known and unknown “forever chemicals” in water that the chemical industry opposes for being too broad. The test they want to use measures total organic fluorine amounts in water and can provide a broader picture of all per- and polyfluoroalkyl substances in a sample instead of testing for one or a few substances at a time.
