Note: NOT ALL SOURCES OF POLLUTION WILL BE IDENTIFIABLE.
STEP 2. If stream quality rating is the same as the previous point sampled, repeat STEP 1, then proceed to STEP 3 when improvement is found at an upstream sampling point.
STEP 3. When a point is found where stream quality improves (e.g., poor to moderate or poor to good), then begin sampling downstream towards the point where greater degradation was found, until the original degraded conditions reappear. When you have located this point, the source of the problem should not be far away.
NOTE: Following periods of very high water, populations of organisms may be temporarily disrupted. This can cause low numbers and diversity which often yields an abnormally low index value. Several weeks to a month may be required to re-establish the benthic community.
IMPORTANT: Should you detect an outfall, pipe, or anything that might indicate a pollutant source, please give this information directly to your local Division of Water office or the Water Watch Program Coordinator in Frankfort at 502-564-3410.
As mentioned earlier in this document, streams in Kentucky are bordered for the most part by private property, which includes the stream bed. Permission from the landowner is necessary for access.
