California Water Views

On March 14, 2025, the Court of Appeal for California’s Fifth Appellate District issued its decision in Sandton Agriculture Investments III v. 4-S Ranch Partners, 2025 S.O.S. 659. That case provided guidance on ownership of captured water and percolating groundwater.

On January 24, 2025, President Trump issued Executive Order 14181 (EO 14181), entitled “Emergency Measures to Provide Water Resources in California and Improve Disaster Response in Certain Areas.” While alluding to assisting Americans in disaster areas generally, EO 14181 largely focuses on significantly changing water management policies in California.

Key Provisions of EO 14181 and the Impact on Water

The first three sections of the executive order are the ones primarily focused on California water.

• Section 1, entitled “Policy,” notes that “it is the policy of the ...

On October 23, 2024, the US Environmental Protection Agency (EPA) announced $276 million in available funding for California water infrastructure projects. When combined with the $269 million it announced on October 8, 2024, that raises the total to $545 million announced this month.

The funding comes through President Biden’s Bipartisan Infrastructure Law, which provides for $50 billion in investments in water infrastructure throughout the country. The October 23 announcement is part of a total of $3.6 billion in available funding, which is designated to particular states ...

The 2024 legislative session ended on August 31, 2024, meaning the legislature passed all bills for this year. All of the bills are currently with Governor Newsom. He has until September 30 to sign or veto any bills. Any bills not signed by September 30 will be vetoed through a ‘pocket veto.’

This session was a busy one for bills affecting the water sector with at least nine bills passed impacting water and sewer systems in California. The bills cover a wide range of topics, including fines for violating State Water Resources Control Board (State Water Board) orders, Proposition 26 and 218 requirements for water-related fees, Sustainable Groundwater Management Act (SGMA) requirements, and the California Water Plan. … 

On August 6, 2024, the Office of Administrative Law (OAL) approved the direct potable reuse (DPR) regulations that were previously adopted by the State Water Resources Control Board (State Water Board) on December 19, 2023. The approved regulations – which go into effect on October 1, 2024 – will allow public water systems and other agencies in California to obtain permits to develop DPR projects.

DPR is when purified recycled water is placed directly into a public water system or into a “raw” (untreated) water supply immediately upstream of a drinking water treatment plant ...

On April 4, 2024, Governor Newsom and the U.S. Bureau of Reclamation (Bureau) announced that the Bureau awarded California $15 million for the Delta-Mendota Canal floating solar project. The project, which is funded through President Biden’s Inflation Reduction Act, marks a key step forward for ‘floating solar,’ a technology that is billed as a win-win for the energy and water sectors. … 

On April 2, 2024, the California Department of Water Resources (DWR) released the California Water Plan Update 2023 (CWP 2023 Update). DWR’s press release dubs the plan “A Roadmap to Water Management and Infrastructure for a Water Resilient Future.” Resiliency is one of the key focuses for the CWP 2023 Update, as its chapter on objectives is entitled the “Roadmap to Resilience.” The plan is focused on the vision that “All Californians benefit from water resources that are sustainable, resilient to climate change, and managed to achieve shared values and connections to ...

The Biden-Harris administration is redoubling its efforts to improve cybersecurity for the nation’s water systems. In March, the U.S. Environmental Protection Agency (EPA) and the White House issued a dire warning to state governors alerting them of the need to protect water and wastewater systems from ongoing cybersecurity threats and requested that the states provide plans to decrease the risk of attacks on water and wastewater systems in their state. … 

On January 31, 2024, the U.S. Environmental Protection Agency (EPA) announced that it is proposing to list nine per- and polyfluoroalkyl substances (PFAS) as hazardous constituents under the Resource Conservation and Recovery Act (RCRA). This action represents another significant step in the regulation of PFAS.

PFAS are a key focus of many environmental regulators and of many people as well largely based on their ubiquity and catchy nickname “forever chemicals.” Both come from the fact that PFAS do not break down naturally over time either in the environment or in the human ...

After releasing the final environmental report (EIR) for the Delta Conveyance Project on December 8, the Department of Water Resources (DWR) certified it on December 21, 2023. The certification of the final EIR is a significant step forward for the Delta Conveyance Project, a key project for the Newsom administration. It also provides the basis for legal challenges, which are all-but inevitable.

The Delta Conveyance Project is the latest in a long line of proposed conveyance projects designed to bring water from northern California to southern California. Different iterations of ...

If there is one truism in California water, it is that there is not enough of it. In part to try to help address that issue, on December 19, 2023, the California State Water Resources Control Board (State Water Board) adopted the state’s first direct potable reuse (DPR) regulations. As detailed in the State Water Board’s press release, the new regulations represent the “most advanced standards in the nation,” provide a “climate-resilient water source,” and “add millions of gallons of additional drinking water.” However, is the picture quite that rosy? … 

Deadlines are upcoming related to the multi-district per- and polyfluoroalkyl substances (PFAS) litigation. The relevant settlements are with DuPont, Chemours, and Corteva (collectively, DuPont) and 3M, parties who allegedly manufactured various PFAS chemicals. The currently-pending settlements cover $1.185 billion for DuPont and $10.5-$12.5 billion for 3M.

The litigation is focused on alleged contamination of drinking water caused by DuPont’s and 3M’s alleged manufacture of PFAS chemicals. PFAS are a family of manmade chemicals that are used due to beneficial ...

Despite efforts to stem increasing cyber threats to water systems around the nation, on October 13, 2023, the United States Environmental Protection Agency (EPA) withdrew cybersecurity mandates put in place by the Biden administration after the 8th U.S. Circuit Court of Appeals July decision to place the mandates on hold while court actions continued.

In an attempt to harden clean water and wastewater treatment facilities from cyberattacks, the administration issued an interpretive memorandum in March 2023, that mandated adding cybersecurity assessments as a regular part of ...

On January 10, 2023, Governor Gavin Newsom announced his $297 billion budget proposal for 2023-2024, which includes a $22.5 billion budget deficit. Despite environmental/climate change programs facing $6 billion in cuts, Governor Newsom’s proposed budget includes relatively few negative impacts to water projects. In fact, the drought response and water resilience section, which includes the vast majority of water-related funding, only faces a cut of two percent, from $8.7 billion to $8.6 billion. That two percent reduction is the lowest of any environmental category. ...  

On December 19, 2022, the U.S. Army Corps of Engineers (Army Corps), Sacramento District released its Draft Environmental Impact Statement (EIS) for the Delta Conveyance Project. The Army Corps is the federal agency tasked with evaluating the Delta Conveyance Project for compliance with the National Environmental Policy Act. Cooperating federal agencies include the U.S. Fish and Wildlife Service, National Marine Fisheries Service, U.S. Environmental Protection Agency, and U.S. Bureau of Reclamation. … 

A key priority of the Newsom administration – the Delta Conveyance Project – has officially entered its next chapter. On July 22, the Department of Water Resources (DWR) released its draft environmental impact report (Draft EIR) for the Delta Conveyance Project.

The Delta Conveyance Project is DWR’s and Governor Newsom’s plan to build an underground tunnel to bring water from the Sacramento-San Joaquin Delta to the State Water Project pumps near Tracy in order to reduce the risk from earthquakes and climate change to the State’s water supplies. It is intended to protect ...

On July 1, 2022 a panel of the Ninth Circuit issued a superseding opinion in California River Watch v. City of Vacaville, Appeal No. 20-16605, withdrawing its previous opinion in the same case and reaching the opposite result. The case is a rare example of a court reversing itself, and has important implications for water suppliers in California and nationwide.

In California River Watch, the plaintiff sought to impose RCRA liability on a water supplier based on the presence of hexavalent chromium in the water it supplied to customers, despite the fact that the water complied with the ...

On June 15, 2022, the U.S Environmental Protection Agency (EPA) announced new health advisories for four per- and polyfluoroalkyl substances (PFAS). The health advisories significantly lowered the level considered safe to consume for two PFAS and set limits for two new PFAS. At the same time, EPA announced it was making $1 billion available in grant funding to help communities address PFAS contamination.

PFAS have been dubbed “forever chemicals” because they tend to linger in the environment and humans rather than naturally breaking down. There are dozens of different types ...

On May 12, 2022, at the conclusion of a 10-hour hearing, the California Coastal Commission voted to deny Poseidon Water’s application to site and operate a desalination plant in Huntington Beach, in what could be a fatal blow for a project that has been debated for more than 20 years.

The Coastal Commission’s vote was unanimous, 11-0, in agreeing with the staff report’s recommendation to reject Poseidon Water’s application. The staff report recommended denial “due to this project’s fundamental inconsistencies with Coastal Act and LCP policies related to coastal ...

Recently, Lyn Clancy, Managing Associate General Counsel and Senior Policy Advisor for the Lower Colorado River Authority, and I presented on the topic of Endangered Species and Water Supply at the State Bar of Texas’ Changing Face of Water Law Conference in San Antonio. Issues of water supply and delivery continue to be a hot topic nationwide, including in Texas, and supply and delivery projects often intersect with the need to address species of plants and wildlife listed under the federal Endangered Species Act (ESA).

The presentation included several primary takeaways ...

World Water Day is an annual United Nations international observance day that highlights the importance of freshwater.  The U.N. chooses a theme for the day each year, and for 2020 the theme is “Water and Climate Change." The goal of World Water Day is to inspire people around the world to learn more about water-related issues and to take action to make a difference. In 2020, in response to the COVID-19 pandemic, there was an additional focus on hand washing and hygiene.  World Water Day is celebrated around the world through political, artistic, and educational events, as well as ...

Yesterday, the Environmental Protection Agency (EPA) released guidance on the coronavirus and the U.S. drinking and wastewater systems.  According to the EPA, “Based on current evidence, the risk to water supplies is low. Americans can continue to use and drink water from their tap as usual.”  The EPA also continues coordinating with federal partners ...
