Yes, wildlife may contribute fecal bacteria to water.
Wildlife, including birds, can contribute fecal bacteria to our waterways. Examples may include waterfowl that seasonally visit agricultural fields in Whatcom County and potentially contribute fecal bacteria pollution to water that drains from the fields. Wildlife such as raccoons or rats can be a pollution problem when animals become concentrated in unnaturally high numbers in an area due to food sources made readily available by people (e.g. pet food outdoors or unsecured garbage).
