Each year millions of people visit the Mono Basin, and most leave only footprints, but some leave a bit more…. Litter is common throughout the basin, but Lee Vining Creek often gets the brunt of it since it’s one of Mono Lake’s most popular tributary streams for fishing and camping.
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?
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.
The [Santa Ana] river bottom area — considered a wildlife preserve — is owned by the California Department of Fish and Wildlife, though the Riverside County Parks Department manages its water quality and habitat.
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.
Four environmental groups have faulted proposed state rules for commercial cannabis cultivation for failing to protect imperiled species, including the reclusive Pacific fisher, from rodent poison frequently used at unregulated grow sites.
Scores of convulsing sea lions are washing up on Central California beaches after eating fish poisoned by a plume of toxic algae that could spread north toward the Bay Area and cause widespread problems, marine biologists said.
A new trial has been ordered in a lawsuit that seeks to hold a fertilizer company financially liable for contaminating a California city’s groundwater.
