Some foam or suds in the stream is natural, especially as snowmelt runoff occurs in the spring. When aquatic organisms, such as algae, die and begin to decompose, fatty acids are produced. These fatty acids are very similar to those found in common soap products. Aeration of the water as it cascades over rocks causes the fatty acids to form foam, often accumulating along shorelines and river banks, and in coves and eddies.
Foam is generally white in color, breaks down relatively quickly, and smells like fish or earth. Foam from silt or erosion is usually a dirty brown color. In contrast, foam from detergent will have a noticeable perfume smell from the additives which give your wash a fragrant scent. Natural foam is often seen in early morning and is usually gone by midday.
If you see foam in the stream that looks like bubble bath, has a perfume scent and doesn't break apart easily, detergent may be in the stream. If so, please notify SEMSWA, 303-858-8844, or Arapahoe County Sheriff’s dispatch during non-business hours.
