DHS news release

Dec. 2, 2004

Contact: Bonnie Widerburg (503) 731-4180; Robert Smith, OPRD (503) 986-0665

Technical contacts: Cindy Gaines, DHS (503) 731-4012; Greg Pettit, DEQ (503) 229-5349


Health advisory for water contact at Sunset Bay State Park beach

What: A public health advisory is now in effect at Sunset Bay State Park beach in Coos County due to higher-than-normal levels of bacterial contamination in beach waters. The Oregon Department of Human Services (DHS) is issuing the advisory in conjunction with the Oregon Department of Environmental Quality (DEQ) and Oregon Parks and Recreation Department.

Local residents and visitors are advised to avoid contact with waters at this beach until the advisory is lifted. Children and the elderly in particular may be vulnerable to waterborne bacteria.

Water tests indicate higher than normal levels of Enterococcus, a type of fecal bacteria, in these waters. Based on the frequency and types of use of Oregon’s ocean waters and federal Environmental Protection Agency (EPA) recommendations, DHS considers an acceptable concentration of Enterococcus to be 158 organisms per 100 milliliters of marine water. Water contact advisories are issued when Enterococcus levels are at or above 158 organisms per 100 milliliters of marine water.

On Nov. 30, beach water tests ranged from less than 10 to 269 organisms/100 milliliters of marine water.

The advisory is in effect beginning today until follow-up samples show that bacterial levels have returned to normal. A news release will be issued when the advisory is lifted.


Action: Local residents and beach visitors should take these precautions while this advisory is in effect:

  • Play on the dry sand or above the high tide line instead of swimming.
  • Do not wade in creeks or in any area where the water is discolored.
  • Stay away from storm drain water or runoff and from ocean waters where runoff flows into the ocean. Maintain a safe distance of at least 100 yards in either direction.
  • Avoid swimming in the ocean within 72 hours after a rainstorm.

Background: Swimming in contaminated water can result in illnesses such as skin rashes, infections of the eyes, ears, nose and throat, and gastroenteritis. Symptoms of gastroenteritis include mild fever, vomiting, diarrhea and stomach cramps. Even when swimming in marine waters with normal levels of bacteria, there is still a 2 percent chance of contracting a swimming associated illness.

Bacterial contamination in coastal recreational waters can originate from a variety of sources, such as shoreline development, wastewater collection and treatment facilities, septic tanks, urban runoff, disposal of human waste from boats, bathers themselves, commercial and domestic animals and natural animal sources such as wildlife.

Water quality is monitored at 12 beaches along the coast under the Oregon Beach Monitoring Program, funded by a grant from the EPA. Water samples are tested for Enterococcus bacteria, a microorganism that has been shown to have a greater correlation in marine waters with swimming-associated illnesses than other bacterial organisms.
