Study Suggests New Climate Threats To California’s Oysters

/in , /by /KQED News (San Francisco, Calif.)by Kevin Stark

In the winter, rainstorms soak California’s coastline. In the spring and summer, strong winds blow waves into the narrow inlet of the Pacific Ocean. For the briny bivalves that live in the bay, this is part of the natural rhythm of life. But now, because of climate change, the torrents of winter rain run with increasing severity, and for oysters, all that freshwater can be dangerous. Summer’s waves bring increasingly acidic water, making it harder for small oysters to build their calcium-based shells. For years, scientists have warned that ocean acidification threaten oysters, but new research from UC Davis suggests that climate change ravages the creatures in a multitude of ways.

Is It Too Late to Save Wild Salmon?

/in , , /by /Bloomberg (New York, N.Y.)by James Tarmy

Some of the world’s most famous conservationists have been hunters. Teddy Roosevelt, John James Audubon, and Ernest Hemingway each have the somewhat dubious distinction of saving animals’ habitats to try to kill them. Pacific salmon aren’t often mentioned alongside Roosevelt’s elephants or Hemingway’s tigers, but in Tucker Malarkey’s Stronghold (Random House, $28), fish is the biggest game of all. Malarkey’s protagonist is a charming misfit named Guido Rahr, who also happens to be her cousin. A naturalist almost as soon as he could walk, Rahr got hooked on fly fishing in his late teens, only to realize, to his horror, that the hydroelectric dams, agricultural runoff, commercial fishing industry, deforestation, and climate change in the Pacific Northwest could bring wild salmon to extinction.

Indoor Water Efficiency at No Cost

/in , /by

There are many ways to use water more efficiently indoors, and a lot of these are completely free! You don’t have to go through the expense of replacing appliances or installing new ones to improve indoor water efficiency. Sometimes it’s as simple as changing a few old water usage habits.

Here are some easy ways to reduce water usage inside your home:

  • Use a bowl of water to help thaw frozen food. Did you know that running the tap to thaw frozen meats and vegetables could use up to 2.5 gallons per minute? Using a bowl of room temperature water instead can greatly improve your water efficiency.
  • Scrape dirty dishes first before rinsing them. Not only will this save you time at the sink, but it will also conserve up to 2.5 gallons of water per minute.
  • Wash fruits and vegetables in a bowl of water instead of running water.
  • Run the dishwasher only when it’s full. Too often people are tempted to run the dishwasher as soon as the sink is empty, but standard dishwashers can use 2-4.5 gallons of water per load.
  • Turn off the water when brushing your teeth. This is possibly the easiest habit to change when it comes to water efficiency, and most people are already doing it.
  • Shorten showers to five minutes or less. Setting a timer on your watch or phone can help with this.
  • Use a bucket to collect water in the shower while you’re waiting for it to warm up. Then use this water to water your plants. Sometimes it can take a while for the shower to get to the right temperature before you step in. This is a perfect time to collect some clean water that can be reused around the house.
  • Wash only full loads of clothing – standard clothes washing machines can use a whopping 15-50 gallons per load. By running the washing machine only when it’s full, you can greatly improve your water efficiency.

Santa Margarita River Project - FPUD - Camp Pendleton

Santa Margarita River Project to Increase Local Water Supply

/in , /by

The San Diego County Water Authority’s Board of Directors voted in July to authorize a Local Resources Program Agreement with the Metropolitan Water District of Southern California and the Fallbrook Public Utility District for the Santa Margarita River Conjunctive Use Project.

The Local Resources Program, managed by MWD, provides funding for local water supply projects. MWD is expected to provide final approval of the project in coming months.

Earlier this year, an agreement between FPUD and Marine Corps Base Camp Pendleton settled a lawsuit that was filed in 1951 over the right to use water from the Santa Margarita River.

Water from Santa Margarita River would reduce imported water demand

The upcoming groundwater recharge project will improve existing facilities and build new facilities to capture surface runoff from the Santa Margarita River. When water flows are high, the runoff would recharge groundwater basins on Camp Pendleton. New and existing wells and pumps will transfer the groundwater to FPUD, which will treat and deliver it to customers.

Water from the river would reduce FPUD’s demand on imported water and minimize Camp Pendleton’s reliance on imported water.

Project would provide 30% of Fallbrook’s total water supply

Facilities will be constructed by Camp Pendleton and FPUD. Camp Pendleton has already constructed its own bi-directional pipeline and related infrastructure, as part of the project, which received congressional funding.

FPUD will construct groundwater extraction wells, a groundwater treatment plant, pump station, storage tank and conveyance and distribution pipelines among other things. The cost of the project is $54.4 million.

FPUD expects construction of the pipeline and treatment plant will begin this fall and take about two years. When completed, the project is expected to produce an estimated 3,100 acre-feet a year. One-acre foot, the equivalent of 326,000 gallons, can supply the average household needs of 2.5 four-person families for one year.

The project would provide about 30 percent of FPUD’s total water supply and nearly all of Camp Pendleton’s water needs.

Plan To Stabilize Del Mar Coastal Bluffs Moves Forward

/in , /by /KPBSby John Carroll

Work to stabilize the coastal bluffs through Del Mar is moving forward, following a vote Monday by the Del Mar City Council. Council members approved an encroachment permit Monday night, allowing SANDAG to work on a 1.6 mile stretch of coastline. This is Phase 4 of SANDAG’s bluff stabilization project, which began 18-years ago. Work has already been completed along the bluffs at the end of 11th Street. The circles seen in the dirt to the west of the train tracks are actually the tops of 65-foot tall pilings that stabilize the bluffs.

Innovative Pipeline 5 Relining Completed

/in , /by

San Diego County Water Authority crews completed relining a segment of Pipeline 5 in Fallbrook and San Marcos in late July, reaching a milestone in a strategic, multi-decade pipeline relining program. The 2.3-mile segment of Pipeline 5 was relined with new steel liners that are planned to last for more than 75 years.

The proactive pipeline relining program is a crucial part of asset management efforts that improve the reliability of San Diego County’s water supplies.

30-year pipeline relining program

Since the relining program began in 1991, nearly 47 miles of pre-stressed concrete cylinder pipe have been rehabilitated. This constitutes more than half of the total PCCP in the Water Authority system. The remaining 35 miles are expected to be rehabilitated by 2027.

The Pipeline 5 project was conducted in eight segments to minimize impacts to the nearby communities of Fallbrook and San Marcos.

Proactive measures to protect infrastructure

Pipeline relining is an efficient technique used on long stretches of pipelines. It involves inserting new steel liners into the existing pipes. The new liners can extend the lifespan of the pipe by several decades.

“Relining our existing pipes is quicker and more cost-effective than excavating, removing and replacing an entire pipeline,” said Gary Olvera, senior construction manager at the Water Authority. “In partnership with our member agencies, the Water Authority has developed an efficient and proactive plan to ensure continued water supply reliability for the entire region.”

Innovative technique to minimize impacts

To access Pipeline 5, crews excavated dirt to create eight 25-foot by 60-foot access portals spaced roughly 525 to 2,500 feet apart. During construction, crews eliminated two of the originally planned portals, helping save more than $217,000. Most of the work was then performed underground, inside the pipe.

Once the new liner was installed, the joints were welded together. Then, each new steel liner was coated with a cement mortar lining. Finally, the portals were backfilled, the pipeline was disinfected, and the pipe was put back into service.

Maintaining regional water supply reliability

Large-diameter pipelines operated by the Water Authority and its 24 member agencies extend approximately 310 miles to convey water throughout San Diego County.

Approximately 82 miles of the pipelines are pre-stressed concrete cylinder pipes. These types of pipes were installed between the early 1960s and late 1980s and some are nearing the end of their service life.

By relining the pipes ahead of time or conducting timely repairs with the latest technology, the Water Authority and its member agencies avoid pipeline failures and improve the reliability of future water supplies.

OPINION: Tax On Bottled Water Puts California’s Most Vulnerable At Risk

/in , /by /Times of San Diegoby Raoul Lowery Contreras

On Aug. 12, California state senators will vote on Assembly Bill 792, which could essentially force all of us to pay millions of dollars more for plastic bottled water or sodas. A nickel here…a nickel there; it won’t be much per bottle. But because there are so many plastic bottles, it quickly adds up to millions of dollars. Consumers will inevitably shoulder the costs, and legislators will inevitably blame corporate greed or environmental measures when confronted about it. Higher-priced bottled water won’t affect average Californians much; either they can afford to not think about the price hike, or they have access to safe tap water.

State Agency Hopeful Chevron’s Massive Kern County Spill Is Finally Over

/in , , /by /KQED-FM (San Francisco, Calif.)by Ted Goldberg

State regulators say they’re cautiously optimistic that a major release of crude oil from a Chevron well in Kern County — an episode that has continued for three months — is finally over. Chevron told state officials Wednesday that more than 1.3 million gallons of oil and water have flowed to the surface in the Cymric oil field, 35 miles west of Bakersfield, since May 10. An estimated one-third of that, or 445,130 gallons, is believed to be crude petroleum. The spill, which Chevron and the state’s Division of Oil, Gas and Geothermal Resources describe as a “surface expression,” has led to a major cleanup operation near the town of McKittrick.

Environmental Groups Move To Sue South Bay Refinery Over Mishandling Of Hazardous Waste

/in , /by /Los Angeles Timesby Anna M. Phillips

Several environmental groups moved Wednesday to sue the Phillips 66 refinery in the South Bay, accusing it of years of mismanaging hazardous waste that could pose a health risk to people living near its Wilmington and Carson facilities. The groups’ planned lawsuit comes four years after the U.S. Environmental Protection Agency first raised concerns about the oil refinery’s practices. Environmental advocates said their decision to take legal action was the result of frustration with what they said was lax oversight by federal and state regulators. “These violations are significant,” said Mary Greene, deputy director of the Environmental Integrity Project, one of the organizations that plans to sue. “This screams of sloppy housekeeping and poor environmental management.”
