Water Quality Data
Here you will find the latest test results from our water quality sampling efforts.
Stars indicate approximate testing site locations.
The Gobler Lab is currently testing for Enterococcus Bacteria and Bluegreen algae.
The Mecox Bay Conservancy makes the data available through this website. Although we indicate when safe swimming standards are not met, we do not make decisions regarding swimmer safety. These determinations are made by County and State Health Department officials.
We are working hard to improve water quality by supporting a number of strategies to reduce contaminants.
