The California Water Boards' Annual Performance Report - Fiscal Year 2010-11

MEASUREMENTS  - Data last updated on: 

WHAT THE MEASURE IS SHOWING

Although not all beaches are monitored every year, high use beaches are monitored regularly. Almost 15,000 monitoring events were conducted in FY 2008-09 during the swim season. A greater number of monitoring events is conducted in the southern California regions, mostly due to higher use and the longer swim season.

WHY THIS MEASURE IS IMPORTANT

California has some of the most popular beaches in the country. Over 150 million day visits are generated annually by tourists and residents to swim, wade, surf, and dive. Beach visitors spend over $10 billion each year in California. Beach water quality monitoring and strong pollution prevention measures are critical for protecting beach goers from waterborne diseases (Beach Regulation and Guidance). Through the Clean Beaches Initiative and other efforts, California has the most extensive and comprehensive monitoring and regulatory program for beaches in the nation. This measure demonstrates the level of monitoring performed by county health agencies in seventeen different coastal and San Francisco Bay Area counties.  Monitoring is also conducted by publicly owned sewage treatment plants, other dischargers along the coastal zone, environmental groups and numerous citizen-monitoring groups (for more background information).

GLOSSARY

Clean Beaches Initiative

In addition to monitoring our coastal water quality, California is committed to improving and protecting beaches along its coast. California has invested $100 million in Clean Beach Initiative grants to fund local projects that reduce bacterial contamination along the coast. The State has also funded research to development more rapid detection methods for knowing when to post beaches, tracking the sources of contamination, and studies to better understand the relationship between bacterial indicators and incidence of disease.
