Contamination a ‘Huge Challenge’ For Affordable Drinking Water in California

Francisco Diaz remembers when the water piped to his home in the Central Valley community of Monterey Park Tract made everything smell rotten, including himself.

“We had to take our clothes and go to the city and wash it over there because if you had washed it here and put it on, you’d stink,” said Diaz, who heads the Monterey Park Tract Community Service District, a form of specialized local government. “We couldn’t even take showers.”

Unsurprisingly, the water was undrinkable. Agricultural run-off, heavy in potentially toxic nitrates, had contaminated both wells that supplied water to Monterey Park Tract, nestled amid the crop fields and dairy farms of Stanislaus County.

Opinion: Tainted Water and the Tijuana River — A Border Tragedy

As I walked along the ocean at Imperial Beach enjoying the sun casting shadows on the waves, several families were wading into the water seemingly not noticing the patrolling lifeguard warning them that the water was too polluted for swimming. I wondered if some swimmers heard the warning so many times – often over 200 days a year – that they became immune to the notice. After all, there was no smell and the ocean looked normal.

 

Little Action on Border Sewage Crisis Since $300M Announcement

Rain fell on San Diego Monday. It wasn’t a lot of rain – an Accuweather forecast called for “a brief morning shower or two” with an anticipated rainfall of 0.01 inches.

But it was enough to prompt a beach closure at the Tijuana Slough, just south of Imperial Beach. That section of the beach is closed whenever the Tijuana River is flowing.

Cross-border sewage spills have been an issue in South County for decades.

Stormwater Could Be a Large Source of Microplastics and Rubber Fragments to Waterways

In cities, heavy rains wash away the gunk collecting on sidewalks and roads, picking up all kinds of debris. However, the amount of microplastic pollution swept away by this runoff is currently unknown. Now, researchers in ACS ES&T Water report that stormwater can be a large source of microplastics and rubber fragments to water bodies and, with a proof-of-concept experiment, show that a rain garden could keep these microscopic pieces out of a storm drain.

Surfrider’s Annual Clean Water Report Highlights Infrastructure Needs and Toxin-Removing Landscapes

Too often, ocean water is laced with sewage and pollutants, affecting how safe beaches are for swimming and surfing –  that’s the message of this year’s Clean Water Report released Tuesday, May 25, by the Surfrider Foundation.

“We believe the water should be clean, always. We should be able to do that in all but the most unusual circumstances,” San Clemente-based Surfrider Foundation CEO Chad Nelsen said. But instead, the report highlights inefficiencies in sewer infrastructure and a need to stop urban runoff before it reaches the coast, both main contributors to dirty water that plagues the country’s coastlines.

Central Valley Water Districts Get OK to Sue Dow, Shell Over Groundwater Pollution

A state appeals court has upheld California’s cleanup standards for a cancer-causing chemical that was added to pesticides and has polluted groundwater in the Central Valley, rejecting challenges by manufacturers that may have to pay the costs.

The State Water Resources Control Board’s 2017 mandate for removing nearly all TCP (1,2,3-trichloropropane) from drinking water was contested by the California Manufacturers and Technology Association, representing Dow Chemical Co. and Shell Oil, which included the chemical in worm-killing fumigants widely used by farmers through the 1980s. They argued that the board’s criteria were not “economically feasible,” as required by state law.

Microplastics are Everywhere. A Nevada Researcher Wants to Know How they Spread

Tiny specks of degraded plastics have been documented in the snowpack around Lake Tahoe — and in the lake itself. They have been found in the Las Vegas Wash. The phenomenon is not unique to Nevada. Microplastics, the end product of our plastic consumption, have been found in ecosystems across the world, even in remote areas.

Microplastics are small — less than 5 millimeters — but they are not uniform. They can have different shapes and vary in size. Microplastics from clothing can appear as synthetic fibers, whereas degraded plastic from bags or water bottles might take on a different composition.

White House, Congress Accelerate Push to Fix Widespread PFAS Pollution

The Biden administration and Congress are stepping up efforts to control the release and cleanup of poly and perfluoroalkyl substances, or PFAS, in drinking water sources and elsewhere, joining states that have expanded scrutiny of the chemicals, which are used widely in manufacturing and are extremely persistent in the environment.

Public Weighs Potential Fixes to Plug Sewage Problem at US-Mexico Border

The San Diego region last year secured $300 million to plug a decades-long wastewater pollution crises in waters that snake across the U.S.-Mexico border and dump raw sewage, trash and sediment into the Pacific Ocean.

On Tuesday, Environmental Protection Agency officials held a virtual public meeting attended by more than 130 people to reveal 10 project proposals being considered to fix crumbing wastewater infrastructure at the border using the $300 million earmarked by the U.S.-Mexico-Canada Agreement (USMCA).

PFAS Water Lawsuits Expose Financial Impacts on State’s Poor Communities

Santa Clarita, a comfortable exurb of some 213,000 residents about 30 miles northwest of Los Angeles, is one of hundreds of California communities and districts grappling with the pricey problem of drinking water that’s been tainted by per- and polyfluoroalkyl substances, chemicals that have been linked to cancer, liver damage, decreased fertility and increased risk of asthma and thyroid disease.
