Wednesday Top of the Scroll: Drinking water of a million people fails California requirements

Almost 400 water systems serving nearly a million Californians don’t meet state requirements for safe and reliable drinking water supplies — and fixing them would cost billions of dollars. More than two-thirds of these failing water systems serve communities of color, and more than half are in places struggling with poverty and pollution, according to an annual assessment released today by the State Water Resources Control Board. These water systems failed to provide water “which is at all times pure, wholesome, and potable,” as required. Some violated drinking water standards for chemicals, bacteria, taste or odor. Others rely on bottled water, or have failed to meet treatment, monitoring or other requirements. … The price tag for ensuring safe, affordable and accessible water supplies for all Californians is staggering — an estimated $16 billion over the next five years — as the state grapples with a multibillion-dollar deficit.

Report exposes inaccuracies in benefit-cost analysis of California’s Delta Conveyance Project

A newly published report challenges the financial feasibility of the Delta Conveyance Project (DCP) as outlined by the Benefit Cost Analysis (BCA) released by the Department of Water Resources’ (DWR). The report from Dr. Jeffrey A. Michael, Director of Public Policy Programs at the University of the Pacific, finds that DWR’s BCA is flawed and inflated, with questionable assumptions, overvalued benefits and a failure to consider major project risks and financial implications. At an estimated cost of $20.1 billion, the DCP represents a substantial financial commitment for water agencies amidst growing financial constraints. The DWR’s BCA claims a benefit-cost ratio of 2.2, suggesting the project’s economic viability. However, Dr. Michael’s review concludes that this ratio is inflated and unreliable due to unjustified optimistic assumptions underlying the analysis.

Navigating the rapid rivers of policy

One of the most contested water management policies in the United States relies on an ill-informed agreement forged more than a century ago. The 1922 Colorado River Compact “ignored available science and overallocated the river’s water,” say the scientist-authors of the lead story in this year’s policy issue. But it’s not too late to change course, they argue in “Fixing the Flawed Colorado River Compact.” Data from rivers and other inland waters can inform policies surrounding climate action and conservation, as well as water management, as evidenced by “Inland Waters Are a Blind Spot in Greenhouse Gas Emissions” and “Kansas Prairie Streams Are Getting Choked, Maybe for Good.” Both articles focus on the sobering challenges of evaluating riverine and riparian ecosystems.

SCOTUS to review EPA wastewater rules

EPA Clean Water Act (CWA) wastewater regulations are set to face U.S. Supreme Court (SCOTUS) scrutiny. In the case City and County of San Francisco v. EPA, San Francisco is suing the EPA over generic water quality prohibitions in permitting decisions. “The EPA had urged the Supreme Court to decline the petition, insisting narrative limitations were within its right,” according to Newsweek. On May 28, 2024, SCOTUS agreed to hear the case.

Wetlands

Sacramento National Wildlife RefugeWetlands are among the world’s most important and hardest-working ecosystems, rivaling rainforests and coral reefs in productivity. 

They produce high levels of oxygen, filter water pollutants, sequester carbon, reduce flooding and erosion and recharge groundwater.

Bay Model

Operated by the U.S. Army Corps of Engineers, the Bay Model is a giant hydraulic replica of San Francisco Bay and the Sacramento-San Joaquin Delta. It is housed in a converted World II-era warehouse in Sausalito near San Francisco.

Hundreds of gallons of water are pumped through the three-dimensional, 1.5-acre model to simulate a tidal ebb and flow lasting 14 minutes.

Salton Sea

As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 237 feet below sea level.

The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe

Drought

Drought—an extended period of limited or no precipitation—is a fact of life in California and the West, with water resources following boom-and-bust patterns. During California’s 2012–2016 drought, much of the state experienced severe drought conditions: significantly less precipitation and snowpack, reduced streamflow and higher temperatures. Those same conditions reappeared early in 2021 prompting Gov. Gavin Newsom in May to declare drought emergencies in watersheds across 41 counties in California.
