The Virginia Graeme Baker Pool and Spa Safety Act (Act) promotes the safe use of pools and spas by imposing mandatory federal requirements for the prevention of suction entrapment and drowning hazards. The Act became effective December 19, 2008 and requires specific American National Standard ASME A112.19.9-2007 safety drain covers on all public pool and spa suction and drain outlets. The Consumer Product Safety Commission administers the Act. In the state of California AB1020 became effective in 2009 and is the equivalent law adopted and enforced by the local enforcement agency representing the California Department of Public Health.
The expiration of drain covers will vary by manufacturer. Check with the manufacturer.

Natural Water Recreational Swim Areas (bay beach, lake, pond)
Alameda County Department of Environmental Health has a collaborative partnership with East Bay Regional Park District for protecting public health by monitoring and notifying the public about the water quality conditions at natural water recreational swim areas (lakes, ponds, San Francisco Bay). East Bay Regional Park District has a Water Management program which includes sampling of swim areas on a weekly basis from April to October to evaluate water quality conditions for public safety. Water sample testing is conducted at a State certified laboratory. California Department of Public Health sets the health standards for recreational beach water safety.
In California, water quality agencies used indicator bacteria categories to determine if there is an increased risk to human health. There are four categories of indicator bacteria: the total number of coliform bacteria per water sample, fecal coliform bacteria, Enterococcus and Escherichia coli. If these indicator bacteria exceed the State standards in a tested water sample, then signage is posted at those locations on the beach to notify the public. The signage uses a simple traffic signal approach which is:
- green = good
- yellow = caution
- red = stop/closed
Green meets State standards, yellow exceeds State standards on one of the indicator bacteria categories and red indicates closure of the beach due to a water quality emergency. For your safety, please do not enter the water if the beach is closed to swimming.
Current water quality results at the swim beaches is posted at: https://www.ebparks.org/about/stewardship/water/default.htm
Water quality conditions in natural recreational areas change constantly. There are a few simple rules to encourage a safe and healthy swimming experience:
- Do not swim in the San Francisco Bay or freshwater lakes for 3 days after a rainstorm due to wind, waves, tidal action and storm runoff.
- Pay attention to lifeguards and water quality signage and information.
- After swimming, shower and towel dry as soon as possible.
- Keep lake and bay water out of your mouth.
- Plan regular restroom visits for children.
- Wash hands with soap and warm water after swimming and before eating.
Swimmer's itch, also called cercarial dermatitis, appears as a skin rash caused by an allergic reaction to certain parasites that infect some birds and mammals. These microscopic parasites are released from infected snails into fresh and salt water (such as lakes, ponds, and oceans). While the parasite's preferred host is the specific bird or mammal, if the parasite comes into contact with a swimmer, it burrows into the skin causing an allergic reaction and rash. Swimmer's itch is found throughout the world and is more frequent during summer months. Learn more about swimmers itch...
