California’s top water regulator on Tuesday approved a definition of microplastics in drinking water, setting the stage for the state to investigate the extent of contamination from the tiny plastics that have been found in fish, waterways, and other habitats.
This summer, the Fleet Science Center in Balboa Park will turn curious kids into happy campers with science-themed summer camps. The Fleet’s Summer Camps provide exciting experiments, intriguing investigations and fantastic fun for kids. Virtual Summer Camps began June 15 and end Aug. 14.

With more people spending time at home due to the coronavirus pandemic, the city of San Diego launched a website Tuesday that provides information and assistance on how to become a successful “urban farmer.” Urban farming can come in many forms and sizes. It can be vegetables grown in containers on a home patio, a community garden that covers one or more city blocks, or raising certain animals such as chickens or bees.
COVID-19 continues to affect parts of California agriculture in different ways. A new report from agricultural economists at the University of California examines the current and long-term impacts on California’s leading agricultural industries.
Profiles in the report illustrate the different ways the pandemic has impacted dairy, beef and produce — industries that have scrambled to repurpose products from foodservice to retail — and tree nuts, an industry that saw a temporary spike in sales as consumers hoarded storable goods. The report includes expert assessments of what the future holds for California’s cattle, dairy, produce, strawberry, tomato, tree nut and wine industries.
To a large extent, the fate of several multi-million dollar water projects on the Monterey Peninsula is in the hands of the California Coastal Commission. The question is whether the commission will grant a development permit for a desalination plant proposed by California American Water—or will the commission deny the permit and implicitly endorse a smaller project that would provide new water to the area by expanding the regional wastewater recycling facility. A vote is expected at the August 12-14 meeting of the commission.
The state’s top water regulator issued a ruling Monday that is likely to have a significant effect on any future development in a large area northeast of Las Vegas, including the construction of Coyote Springs, a proposed master-planned community.
Burrowing owl homes maintained by the Otay Water District received a modern makeover this year. As part of its ongoing environmental mitigation efforts, the District managed construction of new nesting burrows to encourage breeding.
Ten acres of the 240-acre, District-owned San Miguel Habitat Management Area reserve, or HMA, and mitigation bank in eastern Chula Vista is a dedicated native grasslands area where the new artificial burrows are located. The California Department of Fish & Wildlife has designated burrowing owls as a “Species of Special Concern.” They are also protected under the Federal Migratory Bird Treaty Act.

In 2019 with CDFW’s guidance, the District began planning for the retrofit of existing artificial burrows and installation of several new burrows with the most current burrow design, intending to allow for maximized breeding success. The project also enhances the value of the native grassland habitat by removing invasive plants that surround most of the artificial burrows.
“The District’s project to enhance the existing burrowing owl habitat is so important because the HMA is a protected area where the owls can safely live and breed,” said Lisa Coburn-Boyd, Otay Water District environmental compliance specialist. “Increasingly, in San Diego County, the burrowing owl population is declining because of habitat loss and fragmentation.”
Burrowing owls are small owls with bright yellow eyes. Unlike other owls, burrowing owls are active during the day.
Burrowing owls are also quite social. This small raptor lives among others of its own species in loose groups of up to several hundred individuals. They measure seven to 11 inches long and weigh five to nine ounces. Their diet consists of insects, small rodents, amphibian and reptile species, and carrion.
Burrowing owls will take over old mammal burrows as their homes. But in areas where small mammals aren’t present, they will also nest in shallow, underground, human-made structures.

Originally, the District constructed 15 artificial burrows in 2003 as mitigation for impacts to burrowing owl burrows due to reservoir construction and the creation of the former Salt Creek Golf Course. The original burrows used an older design of the artificial burrows and their native grasslands habitat. Although the HMA had regular burrowing owl visitors during that time, breeding success was limited with no owl breeding pairs.
This year, the Otay Water District used the updated burrow design recommended by the CDFW and developed by the San Diego Zoo Institute for Conservation Research. The District retrofitted and enhanced five existing burrows and installed six new burrows. During construction of the burrows in January and February, two burrowing owls seemed interested in the construction. No breeding pairs have used the burrows this season. The District hopes they will be back to move into the newly completed burrows.

A Cooper’s hawk chick and its nest received special attention after being discovered recently near a San Diego County Water Authority construction project.
Environmental surveyors spotted the nest on March 27 south of Gopher Canyon Road during the Pipeline 5 repair project in Moosa Canyon in North San Diego County.
Most people take it for granted. You turn the faucet on, and water comes out.
But it isn’t that simple. In fact, it’s far more complicated to fill a glass with clean drinking water.
That’s one of the reasons why the City of San Diego’s Public Utilities Department is mailing residents the annual Drinking Water Quality Report this week.
“A lot of people just think that when you turn the tap water on, it’s just coming from the lakes and the streams,” said Michael Simpson, the Senior Water Operations Supervisor at the Alvarado Water Treatment Plant near Lake Murray.
The Scripps Institution of Oceanography in San Diego will host a major research initiative funded by the federal government.
UC San Diego will host the Cooperative Institute for Marine, Earth and Atmospheric systems, and it will get up to $220 million in funding for research over a five-year period.
The National Oceanic and Atmospheric Administration is making the investment locally after a competitive bidding process.
