If stream quality is rated as poor, a definite problem is indicated. Poor quality condition may have a specific and observable source, such as a sewage treatment plant outfall or an industrial discharge. For purposes of attempting to locate the problem area, follow the procedural methods that are described below.
Note: NOT ALL SOURCES OF POLLUTION WILL BE IDENTIFIABLE.
Follow These Steps To Locate The Possible Source Of A Poor-Quality Condition:
STEP 1. Select a convenient access point (such as a bridge) with the proper sampling conditions as described in "The Kick-Seining Technique," approximately one mile upstream from the point of noticeable degradation. After sampling this area, GO TO STEP 2.
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 toward 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 poor 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. If an actual spill or release of a hazardous material occurs or when there appears to be a threat of severe environmental harm, the Environmental Response Team can be reached 24 hours a day, 7 days a week. To report an environmental emergency call 502-564-2380 or 1-800-928-2380.
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.
