High nitrate levels were observed in Stillhouse Hollow Spring. These levels are of concern for aquatic life. Deformed salamanders were found in the spring run, and although the cause for the deformity is unknown, parameters with abnormal levels are being investigated and those levels are reduced where possible. To reduce nitrates, the source must be identified. Lawn fertilizer appears to be the most likely source of nitrates, while leaking sanitary sewer lines and bat guano are not major contributors.
