North Coast water regulators are taking another run at a comprehensive program to prevent bacterial contamination of the Russian River, one that includes provisions likely to have significant impacts for thousands of homeowners dependent on aging septic systems.
There are over a hundred water systems in California that have tested above the new maximum contaminant level for 1,2,3-trichloropropane (TCP), a man-made chemical and known carcinogen found in the state’s groundwater.
Even after the Flint scandal reawakened the nation to the dangers posed by lead drinking water pipes, the U.S. Environmental Protection Agency appears to be in no rush to strengthen federal health standards.
Nutrients – such as nitrogen – are essential to life, but an overabundance can mean trouble for waterways. Take Chesapeake Bay and the Gulf of Mexico, which are infamous for “dead zones” where closely packed bodies of fish float to the surface or wash ashore by the thousands. These dead zones are caused by nutrient pollution, which makes algae grow too fast.
When a therapy dog refused to drink at a San Diego grade school, it was the first clue that something was wrong with the water. Tests revealed why the pup turned up its nose—the presence of polyvinyl chloride, the polymer in PVC pipes that degrade over time. But further analysis found something else that had gone undetected by the dog, the teachers and students of the San Diego Cooperative Charter School, and the school district: elevated levels of lead.
Los Angeles has big, big plans for revitalizing an 11-mile stretch of the [Los Angeles] river over the next several years, at a price tag that began at $1 billion and soon bumped up to an estimated $1.6 billion. But is the water clean enough for recreational use, or to be a draw for people to live or work along the banks of what amounts to a drainage ditch for urban storm runoff and treated sewage?
Tom Steyer, the San Francisco billionaire and environmentalist, promised his support Tuesday for a proposed safe and affordable drinking water fund to help communities with contaminated water in the San Joaquin Valley. … Steyer met with about a dozen water advocates at the nonprofit Leadership Counsel for Justice and Accountability in downtown Fresno who urged him to throw his clout behind Senate Bill 623.
The Orange County Transportation Authority board on Monday, Aug. 14, unanimously allocated more than $3.1 million to 16 cities for projects to improve water quality, addressing a promise to voters of environmental investment.
Two popular swim spots — Lake Temescal in Oakland and Quarry Lakes in Fremont — will reopen Saturday after blooms of toxic blue-green algae finally cleared up, the East Bay Regional Park District announced Friday.
An annual analysis of the planet’s climate reaffirms what researchers knew was the case: that 2016 was the hottest year since at least 1880, when reliable global measurements were first kept. … The atmosphere is not only the place with incremental warming: the world’s freshwater lakes are also heating up.
The Russian River tested clean this week for a toxin related to blue-green algae that prompted cautionary signs at 10 popular beaches last month and in each of the past two summers. The river remains open to swimming and other recreation.
Federal water-quality officials on Thursday released a list of actions taken in recent years to stop wastewater from flowing from Mexico into the San Diego region, a little more than a week after the city of Imperial Beach threatened a lawsuit.
If you drive Highway 99 through California’s Central Valley, you’ll pass through the heart of farm country, where the state’s bounty blooms with hundreds of crops – everything from peaches to pistachios, from tangerines to tomatoes. You’ll also pass through dozens of communities, large and small, whose water systems are tainted by a newly regulated contaminant, 1,2,3-trichloropropane (TCP), which for decades was used in agricultural fumigants injected into farmland across the Valley.
Developers in the city of San Diego are facing tougher government enforcement at construction sites that have the potential to pollute rivers and streams — including fines and even stop-work orders. That’s the result of a settlement San Diego officials entered into with water quality regulators that will require the city to pay $3.2 million and step up policing of development.
