Swimming in the Willamette River is fine most of the time. During the summer, Environmental Services regularly tests for E. coli bacteria to make sure that it’s safe.
Green infrastructure filters pollutants and helps recharge groundwater. Portland has more than 1,500 green street planters.
None of Portland’s waterways meet all water quality goals. Pollutants like copper from car brake pads can harm salmon.
