GALVESTON, Texas -- Just in time for Labor Day, 17 beaches on Galveston Island have posted advisories warning of high levels of bacteria in the water.

Swimming is not recommended when bacteria levels are elevated.

Over the past few months these warnings have been issued off and on for Galveston Island's beaches, but over a holiday weekend they are reason to think twice about exposure to the beach water.

Galveston County Health District spokesman Kurt Koopmann said more water samples are being collected for testing today. He said that after heavy rains, bacteria levels rise.

Whenever you have a lot of rain, things that elevate bacteria levels usually get into the waterways, Koopmann said, alluding to waste and road runoff. Some months we have no advisories, and sometimes we have many.

The following beaches have advisories attached to them at this time:

  • San Luis Pass Toll Bridge
  • Terramar Beach
  • Sea Isle South
  • 16 Mile Rd.
  • Jamaica Beach South
  • GISP #2
  • GISP #4
  • GISP #6 - Bayside
  • 13 Mile Rd.
  • Pirates Drive
  • Bucanneer Blvd.
  • 11 Mile Rd.
  • Pabst Rd.
  • Spanish Grant Blvd.
  • Hershey Beach
  • 8 Mile Rd.
  • 7 Mile Rd.
