This map shows the relative proportion of non-attaining vs. attaining waterways. Under the Clean Water Act, the PA DEP protects four stream water uses: aquatic life, fish consumption, potable water supply and recreation. If a stream segment is non-attaining for any of the four causes, it is deemed impaired and is displayed in yellow. See "non-attaining use" for cause of designation.
