San Francisco’s famously pure High Sierra water is about to be served with a twist. Starting next month, city water officials will begin adding local groundwater to the Yosemite supplies that have satiated the area’s thirst since the 1930s and made the clean, crisp water here the envy of the nation.
In the end, the much-maligned chloramines did their job. One year after the city of Stockton began treating the north side’s drinking water with the new chemical, levels of a cancer-causing byproduct have plummeted nearly 70 percent, on average, and are now well within federal standards.
Erin Brockovich parachuted into Stockton one year ago to condemn the city’s use of a common method to treat the drinking water. But sitting on a stage before a raucous crowd of 1,200, in the heart of a region deeply opposed to Gov. Jerry Brown’s proposed Delta tunnels, the celebrity activist won enthusiastic applause when she accepted a new challenge.

The city of Fresno wants to hire two national experts on corrosion in municipal water systems to reduce the odds that discolored-water problems now plaguing northeast Fresno will repeat themselves when a new water treatment plant opens in 2018.
An environmental group said Monday that 55,000 people statewide are at risk of drinking tap water contaminated with arsenic, and many of the communities are poor, mostly Latino towns in the San Joaquin Valley.
Directly detecting harmful pathogens in water can be expensive, unreliable and incredibly complicated. Fortunately, certain organisms are known to consistently coexist with these harmful microbes which are substantially easier to detect and culture: coliform bacteria. These generally non-toxic organisms are frequently used as “indicator species,” or organisms whose presence demonstrates a particular feature of its surrounding environment.
Tania Ramirez stepped into her family’s front yard Friday morning, leaned down toward a pipe protruding from the garden, and twisted a spigot. For the first time in three years, water came pouring out.

In California, cyanotoxins have become more of a problem amid the drought and the same toxin that shut down Toledo’s water supply has been detected in lakes, reservoirs and streams across the state. But because standard treatment processes usually get rid of cyanotoxins, water officials say it’s unlikely a similar crisis would unfold here.

The state is currently investigating whether it is feasible to develop standards for direct potable reuse, which would allow treated wastewater to be sent direct to customers for drinking without first being stored in a reservoir or aquifer.
A vocal and growing number of residents in northeast Fresno are convinced water from the city’s Surface Water Treatment Facility is primarily responsible for corrosion in their pipes, causing discolored water – and in several dozen instances, lead contamination – to flow from their household faucets.
Fresno leaders will be sending direct-mail fliers this week to every water customer in the northeastern area of the city, substantially expanding the scope of an investigation into discolored water coming from faucets in hundreds of homes as well as lead contamination in about 40 homes.
Hundreds of homes in northeast Fresno have discolored water – and, in some cases, excessive levels of toxic lead – coming from their faucets. And while homeowners clamor for answers about why and what to do about it, those answers are in painfully short supply.
I’ve [T. Christian Miller] received a lot of questions about applying investigative reporting techniques to figuring out whether your water is safe — the stuff in your taps, the stuff in your rivers, the stuff at the beach. … The difficulty is partly due to the complexity of the topic. Water is not simple.

Chapter 13 of the Siskiyou County Code governs the withdrawal and transport of groundwater, and section 3-13.301 does not allow the unpermitted transport of water from the county; however, “commercial water-bottling enterprises” are exempt from requiring such a permit.
Teflon and related brands Gore-Tex, Scotchgard, and Stainmaster — all prized for their water-repelling, stain-protecting, and mess-preventing attributes — seem to contain magical properties. … Last month, seven years after it issued the first health guidelines for PFOA/PFOS in drinking water, the U.S. Environmental Protection Agency lowered the recommended level in drinking water to 0.07 parts per billion combined.

A recent article, “Behind the Lawsuit to Turn Off Spigot to Nestle,” showed one perspective on the U.S. Forest Service (USFS) process to renew Nestle Waters’ special-use permit to transport water through the forest. Here is another. First, Nestle Waters holds senior water rights dating back to the 1880s in the San Bernardino National Forest.
Activists who are trying to block Nestle’s bottling of water from a national forest have questioned the company’s claim that it holds water rights dating to the 1800s. Now California regulators are conducting an investigation to get to the bottom of the dispute.

A growing distaste and distrust of tap water has prompted many school districts to spend thousands of taxpayer dollars on heavily marketed filters — some of which use a process that discards some water as waste — even though the schools say there’s nothing wrong with what’s currently flowing from their pipes.
San Bernardino National Forest officials will host an open house Thursday to answer questions and discuss the process for environmental studies of Nestlé water bottling operations in a rugged canyon north of here.

Local water activists Barbara Barrigan-Parrilla and Bill Jennings spoke before [Bob] Bowcock and [Erin] Brockovich. Both suggested to the audience there are more significant issues facing Stockton and the region than chloramines, most notably the proposed Twin Tunnels project in the Delta.
U.S. Environmental Protection Agency officials were in Carlsbad on Wednesday to announce more than $182 million in federal funding that will be funneled to drinking water and wastewater infrastructure improvements throughout California.
The recent addition of chloramines to treat Stockton’s drinking water is not on Tuesday night’s City Council meeting agenda, but a rally on the hot-button issue is scheduled nonetheless late in the afternoon outside City Hall.
Over several years, the plan to put chloramines in north Stockton’s drinking water was vetted in public by the City Council and by a citizen oversight group. … But it was a Facebook post late Saturday by renowned environmental activist Erin Brockovich that turned a mostly non-controversial issue into a firestorm of public outrage.

This issue of Western Water examines PPCPs – what they are, where they come from and whether the potential exists for them to become a water quality problem. With the continued emphasis on water quality and the fact that many water systems in the West are characterized by flows dominated by effluent contributions, PPCPs seem likely to capture interest for the foreseeable future.
