Monitoring Beach Water Quality
The Oregon Beach Monitoring Program monitors the waters along Oregon's coastline for the presence of fecal bacteria, and reports elevated levels to the public.
Marine waters are tested for enterococcus, which is an indicator of the presence of other bacteria. Enterococcus is present in human and animal waste and can enter marine waters from a variety of sources such as streams and creeks, storm water runoff, animal and seabird waste, failing septic systems, sewage treatment plant spills, or boating waste.
The beach sampling season runs from Memorial Day in May through Labor Day in September. Although occasionally when resources allow, off-season monitoring is performed for the purpose of research, beaches are normally not monitored outside of this window.

Water Quality Data
The OBMP works with the Oregon Coastal Atlas to share and display beach water quality monitoring data. View recent and historic sampling data at www.coastalatlas.net.
Other programs within the Oregon Public Health Division are looking at beach quality and impacts to public health. Radiation Protective Services within the Center for Health Protection are looking at the potential affects of tsunami debris on Oregon's beaches. You will read about the work being done, radiation monitoring data and how you can help.
