This summer, WSU Beach Watchers volunteers are monitoring the quality of water at Mission Beach each week until August 29. Harvey Eastman at the Tulalip Water Quality Lab analyzes the water samples. So far, the beach has been sampled eight (8) times.
The results show that bacteria levels in the water are low, well below the threshold limit for swimming, which means that the water is clean! The graphs below show the average result from the three beach sampling stations for this year as well as last year. The red line shows the bacteria threshold limit and the blue line is the amount of bacteria in the water at Mission Beach. If bacterial levels are above the threshold limit, there are more chances for skin infections or gastrointestinal illness from too much pollution.
