MONITORING FREQUENCY

Agate Beach - Big Creek is sampled bi-weekly from May 26th to September 1st

SOURCE INFORMATION

Some freshwater sites on Oregon beaches are tested for Enterococci on a regular basis between Memorial Day to Labor Day, as part of the Oregon Beach Monitoring Program (OBMP).

The Environmental Protection Agency (EPA) recommended the use of enterococci for fresh and marine recreational waters because they found enterococci to be a very good predictor of illness in all waters. For this reason EPA allowed states and tribes to select the easiest most reliable pathogen indicator based on the individuality of the locations being sampled. The OBMP chose enterococci because many of the sites sampled that appear to be fresh water are often brackish and sometimes marine due to tidal influences, making enterococci a better choice for coastal watersheds.

OBMP issues health advisories for exceedences in marine waters only. This includes the surf, as well as streams that impact the beach and surf that come from fresh water sources. Streams or pools of water on the beach and areas of a stream where salinity is above 1.o parts per thousand are considered marine samples. Fresh water samples are often collected upstream of monitored beaches for use in investigating potential sources of high bacteria. These samples can assist the OBMP, the Department of Environmental Quality (DEQ), local governments and Swim Guide to address these fresh water quality issues, by helping to implement find and fix projects.

To receive regular updates on OBMP data during the monitoring season,please email the OBMP Program Coordinator attara.a.chetock@state.or.us

The EPA recommended criteria for Enterococci in fresh water at beaches characterized as having moderate full body contact recreation (as in Oregon) are as follows:

33 cfu/100mL for a 30 day mean, and

78 cfu/100 mL for a single sample

Swim Guide marks a site green when a freshwater sample is less than 78 cfu/100 mL.

Swim Guide marks a site red when a freshwater sample is equal to or more than 78 cfu/100 mL.

A site is marked grey when there is no current or reliable water quality information available.
