As drought-stricken Arizona bakes in searing heat, the Scottsdale City Council unanimously agreed this week to ban natural grass in front of future single-family homes in an effort to conserve water.
The new ordinance will apply to new houses constructed or permitted after August 15.
This week the U.S. Court of Appeals for the Eighth Circuit granted a request from the American Water Works Association (AWWA) and the National Rural Water Association (NRWA) to stop the U.S. Environmental Protection Agency’s Cybersecurity Rule from going into effect until a current case challenging the rule has been decided.
According to the National Oceanic and Atmospheric Administration (NOAA), El Niño is here. Its arrival likely augurs an increased occurrence of health threats around the world. Brought on by deviations in sea-surface temperatures, El Niño negatively impacts human, animal, and plant health—and their interconnections. According to the World Health Organization (WHO), the changing atmospheric conditions brought on by El Niño will increase the risks for droughts, fires, floods, and storms that can lead to the increased incidence of vector-borne diseases, food insecurity, and heat stress, among other health threats.
A senior Interior Department official who has had a key role in negotiations over the shrinking Colorado River plans to step down from the job next week.
Tanya Trujillo told the department of her intention to resign as assistant secretary for water and science about six weeks ago and her last day is Monday, she told The Associated Press. Trujillo, who has served in the role since June 2021, said it made sense to leave now as the Biden administration gears up for a reelection campaign.
California has taken a big step towards boosting how much sewage water local governments can purify and reuse for drinking — a process known as water recycling. On Tuesday, the state proposed draft regulations to expand recycling by introducing new purification standards and processes.
The Board of Directors of Humboldt County Services District voted Tuesday for water and sewer rate increases, with two of five directors dissenting. Rates would eventually increase over the next five years by a total of 88% and start increasing Aug. 1.
California’s effort to secure water supplies is a struggle older than the state itself.
It played out during the Gold Rush, and it defines modern San Francisco and Los Angeles. It has created divisions between north and south as well as east and west.
From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of scientists says a new geologic epoch began then.
Called the Anthropocene — and derived from the Greek terms for “human” and “new” — this epoch started sometime between 1950 and 1954, according to the scientists. While there is evidence worldwide that captures the impact of burning fossil fuels, detonating nuclear weapons and dumping fertilizers and plastics on land and in waterways, the scientists are proposing a small but deep lake outside of Toronto, Canada — Crawford Lake — to place a historic marker.
A wet and cool start to 2023 helped Southern Nevada consume 25 percent less water from the drought-stricken Colorado River through the first five months of the year.
From January through May, the region’s consumptive use from the river was just under 61,000 acre-feet of water, Warren Turkett, a natural resource analyst for the Colorado River Commission of Nevada, told commissioners Tuesday. That’s down from nearly 82,000 acre-feet of water consumed during the same time period last year, which was near the same amount the valley consumed in 2021 (84,489 acre-feet) and 2020 (80,885 acre-feet).
Lake Mead has risen more than 3 feet over the past month, and nearly 13 feet since Jan. 1.
The lake, which supplies 90% of the water used in the Las Vegas valley, is bucking the trend of the past five years. Lake Mead typically drops beginning around April, following a seasonal pattern.
As snow melts upstream in the Upper Colorado River Basin, water is held back in dams all along the way to prepare for higher consumption during the hot summer months. Water eventually reaches Lake Powell before flowing through the Grand Canyon and into Lake Mead.
