Stay Informed on Construction Industry Water Quality News

News on recent important developments in water quality regulatory and policy-making activities in California and Washington D.C.

Construction & Building Industry News

Each month, CICWQ collects news and information on water quality and water supply reliability topics. Articles cover a wide range of issues affecting the construction industry: water quality and wetlands regulations and policies, water supply, sewer system, and stormwater drainage improvement efforts, and multi-benefit, regional water supply reliability project development.

CICWQ also publishes technical articles and reports periodically and prepares presentations that emphasize water quality research and findings specific to the construction industry.

Analysis of Construction Industry Stormwater Permit Enforcement Data and Recommendations for Industry Improvements

CICWQ uses State of California enforcement reporting data on rates of compliance and types and numbers of violations each year to produce summary presentations relevant and specific to the construction industry. Analysis of the data supports education in permit compliance and where specific actions are working and where improvements are needed.

Evaluation of Soil Erosion and Sediment Control Products for Release of Heavy Metals

CICWQ worked with researchers at San Diego State University Soil Erosion Research Laboratory to examine 19 different construction site erosion and sediment control best management practices (BMPs) for their ability to control sediment and metals in stormwater runoff. The study was done to assist in the selection of BMPs for construction sites that are required to meet Total Maximum Daily Load (TMDL) regulations in the Los Angeles River and San Gabriel River watersheds in southern California.

Stormwater Runoff Following Wildfire in Southern California

CICWQ and the Construction Industry Advancement Fund, along with other collaborators, provided funding to SCCWRP to conduct a comprehensive analysis of loading of stormwater runoff following wildfire in Southern California. Work was done to research and build the scientific record concerning the natural loading of sediment and other constituents in stormwater runoff from areas following wildfire and areas unburned.
