Groundwater Remediation as Potential Tool to Combat Water Scarcity: Navigating Potential Conflicts Between CERCLA Remediation Considerations and Water Policy Issues

New water supplies in the western United States are likely to come from a panoply of non-traditional sources, including storm water capture, waste water recycling, desalination, infrastructure efficiency improvements, and other conservation measures. One potential new water source for municipalities is contaminated groundwater requiring environmental remediation, that, but for its low quality, could be used as water supply. Exploring this option is especially appealing in water stressed regions, such as much of the western United States. For example, in southern California, the Metropolitan Water District supports “[r]ecovering degraded groundwater supplies for municipal use” as part of its Local Resources Program.

Big Food Brands Commit to Conserve Water, Soil – and the Climate

Not long ago, the United Nations warned that water scarcity could be experienced by 40 percent of the world’s population by 2030. Last week, top U.N. scientists reported that problems associated with a warming climate, including drought, water scarcity and pollution, are likely to be worse than previously thought unless we work to hold the average global temperature rise to no more than 3.6F(1.5C). These warnings may seem daunting, but some of the world’s most influential companies are making strides that could significantly help alleviate worsening global water challenges.

Pure Water Moves Forward, Construction Beginning Soon

San Diego’s goal to provide one-third of its own water by 2035 took a major step recently when the City Council approved a low interest loan that will finance nearly half of the first phase of the Pure Water program. The $614 million loan comes from the EPA’s Water Infrastructure Finance and Innovation Act (WIFIA) and will cover 49 percent of the $1.25 billion project. The WIFIA program was created to accelerate investment in the nation’s water infrastructure by providing long-term, low-cost supplemental loans for regionally and nationally significant projects.

Another Hot and Dry Winter for LA?

Los Angeles is in for another hot winter, with little chance for relief from drought conditions that now exist throughout California, according to a new forecast from the National Oceanic and Atmospheric Administration. That’s in spite of a probable El Niño event, which could bring above-average rainfall to the southwestern United States. The NOAA estimates that there’s a 70 to 75 percent chance that an El Niño develops in late fall or early winter, but it’s likely to be a weak El Niño, meaning that it’s less likely to bring higher than average rainfall to Southern California.

District Poised to Capture More Stormwater Thanks to Army Corps of Engineers

Historically the Orange County Water District (OCWD) has had to rely on Mother Nature for water. Although, due to climate change, that is no longer a realistic water strategy for OCWD. The agency has instead made significant investments in cutting-edge technology, such as water reuse, to help the region weather droughts. However, not taking advantage when large rain events take place is not something OCWD wants to miss out on and has found a way to capture more stormwater without having to spend tens of millions of dollars in new infrastructure.

Why California Law Requires a Clear Benefit for Groundwater Recharge

Researchers at the University of California recently highlighted a flaw in state law that may prohibit diverting streamflow to recharge groundwater. The problem is that groundwater recharge by itself is not considered a “beneficial use” under state law, and meeting that definition is a requirement to obtain a permit to divert water. Officials at the State Water Resources Control Board, which oversees water rights, say the reality is not so clear-cut. In fact, existing rules allow most groundwater recharge projects to obtain a water right.

County Offers Discounted Rain Barrels

The Solana Center for Environmental Innovation and the County of San Diego are offering discounted rain barrels to encourage harvesting of rainwater. By using a rain barrel, county residents can reduce pollution from runoff, conserve water and save money on their water bills. The cost is $90 per 50-gallon rain barrel, but residents of incorporated cities can qualify for a $35 rebate per rain barrel on up to two rain barrels per household, bringing the cost to $55 each. Residents of unincorporated areas of the county can get an additional $30 discount, (limited to two discounts per household) for the first 200 rain barrels sold.

City Councilman Calls for Big Fixes at Public Utilities Department

City Councilman Scott Sherman wants significant changes at the San Diego Water Department. Sherman’s call for action came Oct. 16, during a city council discussion of an independent audit of the problem-plagued department. That audit, along with reporting by the NBC 7 Responds team, uncovered significant delays in the department’s effort to replace broken water meter boxes and lids. Auditors also discovered that some department employees were working less than four hours of their eight-hour workday.

Metropolitan Water District Looks to Reduce Greenhouse Gas Emissions, Address Climate Change

The Metropolitan Water District (MWD) Board of Directors has voted to develop a Climate Action Plan with a goal of providing a complete framework of how to reduce the district’s carbon footprint. The plan will include reducing the greenhouse gas emissions (GHG) produced in the delivery of water to Southern California as well as a comprehensive plan to combat climate change. The MWD board also voted to award an $815,000 contract to Rincon Consultants, Inc. to assist in creating the plan, which will be developed over the next 18 months. Rincon Consultants maintains more than a dozen offices in mostly Southern and Central California.

State High Court Rejects Berkeley Group’s Suit to Drain Hetch Hetchy Reservoir

The California Supreme Court rejected a conservation group’s lawsuit Wednesday seeking to drain Yosemite’s Hetch Hetchy Reservoir, a source of water for San Francisco and surrounding Bay Area communities. Restore Hetch Hetchy, a Berkeley group, argued in its suit that the location of the dam and reservoir, which flooded a valley in the park after construction in 1923, violates a provision of the California Constitution requiring reasonable water use. But a state appeals court in Fresno ruled in July that Congress had overridden state laws when it authorized construction of the dam and reservoir.
