**Update: This advisory was lifted the afternoon of Friday, June 24.

A swimming advisory has been issued for the waters of Weeks Bay at Camp Beckwith in Fairhope.

According to the Alabama Department of Public Health, two recent successive tests of swimming water quality were poor, and swimming in this area may lead to an increased risk of illness.

Monitoring will continue, and the advisory will be lifted once bacteria values fall below the Environmental Protection Agency’s threshold of 104 enterococcus organisms per 100 milliliters for marine water.

According to a news release, the ADPH and Alabama Department of Environmental Management operate the bacteriological water quality monitoring and notification program under a grant from the EPA’s BEACH Act Program. This program involves the routine collection of water samples from 25 high-use coastal recreational sites.

These samples are analyzed for enterococci bacteria. High counts indicate the possibility that other disease-causing germs could be present in the water. Based on EPA’s “Criteria for Bathing (full body contact) Recreational Waters,” samples are checked for enterococcus bacteria. These indicator bacteria are inhabitants of the intestines of humans and other warm-blooded animals.

Bacterial concentrations in recreational waters can increase during and immediately following rainstorms due to overflowing sewage collection and treatment facilities, storm water run-off, malfunctioning septic systems and agricultural run-off.

According to the public health department, no known sewage spills have occurred.

When monitoring results exceed the EPA standard, the affected site is immediately retested. If the results of the second test identify enterococci levels persisting above the EPA standard, a public advisory is issued.
