An expert advisory panel convened by SCCWRP on behalf of the State Water Board to update recommendations for monitoring CECs in recycled water has released its final draft report. The … More

A field crew retrieves sediment samples collected from Consolidated Slip in Los Angeles Harbor during a SCCWRP-led study examining how to optimize the design of toxicity identification evaluation (TIE) studies to improve confidence in the results.

Study offers guidance for optimizing TIE study design

SCCWRP and its partners have completed a two-year study examining how to optimize the design of toxicity identification evaluation (TIE) studies to improve confidence in the results. The project, published … More

SCCWRP is part of a research team that will examine how ocean acidification is impacting Dungeness crab in the Pacific Northwest. This commercially important species relies on minerals in seawater to form its protective outer shell; the supply of these minerals is decreasing as a result of ocean acidification.

Model being developed to predict acidification’s impacts on Dungeness crab

in Climate Change, Ocean Acidification and Hypoxia Comments are Disabled

A group of researchers, including SCCWRP, has launched a three-year project to develop a model that predicts impacts on the Pacific Northwest Dungeness crab industry from ocean acidification. The project, … More

Pteropods, or sea snails, are sentinel indicators of the biological impacts of ocean acidification. SCCWRP is taking part in a study examining whether acidification is triggering shell dissolution in the Beaufort Sea near the Arctic Circle.

Pteropod health to be evaluated to track ocean acidification

in Climate Change, Ocean Acidification and Hypoxia Comments are Disabled

SCCWRP has teamed up with Canada’s Department of Fisheries and Oceans to examine whether pteropods in the Beaufort Sea are showing signs of shell dissolution triggered by ocean acidification. The … More

Study launched to optimize kelp yields, explore approach to combatting ocean acidification

in Climate Change, Ocean Acidification and Hypoxia Comments are Disabled

A group of researchers, including SCCWRP, has launched a study to identify areas in the San Pedro Basin that are ideal for cultivating kelp, as well as the environmental conditions … More

San Diego’s Tourmaline Surfing Park is at the receiving end of a storm drain channel, making it susceptible to land-based runoff during rainfall.

Microbes in sewer pipes to be studied to glean insights about origins of fecal contamination

in Microbial Source Tracking, Microbial Water Quality, Top News Comments are Disabled

SCCWRP and its partners have launched a study investigating whether the microbial community that grows inside sanitary sewer pipes could provide insights into the origins of human fecal contamination found … More

Barnacles, algae and other marine life attach to the underside of a boat that has been raised out of the water. Copper-based paints play a key role in preventing this fouling, but because the copper dissolves in water, the water-quality regulatory targets for copper in places like Marina del Rey Harbor have been exceeded. SCCWRP and its partners are pursuing a study examining whether the regulatory target for copper should be modified to more accurately reflect its ecological threat.

Study launched to revisit copper TMDL for Marina del Rey Harbor

SCCWRP has launched a two-year study examining whether existing regulatory targets for dissolved copper in Marina del Rey Harbor should be modified to more accurately reflect the ecological threat posed … More

SCCWRP and its partners have developed a series of hydrologic maps that estimate the historic flows of ephemeral streams. The maps above show flow conditions in the Santa Ana region in January, left, and July, right, under three different types of seasonal rainfall patterns (dry, normal, and wet). From these interactive, customizable maps, watershed managers can understand the dynamic nature of ephemeral stream flows over time.

Technical foundation created for ephemeral stream tools

in Bioassessment, Indices of Biotic Integrity, Top News Comments are Disabled

SCCWRP and its partners have completed a pair of studies that establish a technical foundation for building watershed management tools for Southern California streams that run dry for much of … More

The Santa Margarita River watershed has been grappling with algae proliferation and low dissolved oxygen levels as a result of excess nutrient inputs. Researchers are assembling a suite of models to establish scientifically defensible nutrient loading targets intended to protect the lower watershed from these bloom events.

Models being built to establish nutrient loading targets for Santa Margarita River

in Eutrophication, Harmful Algal Blooms Comments are Disabled

SCCWRP and its partners have begun assembling a suite of models to support development of scientifically defensible nutrient loading targets for reducing eutrophication in the lower Santa Margarita River watershed. … More

20 years of nutrient input data compiled for acidification model
