An assembly is disclosed for mounting a pH probe in a flowing solution, such as a sanitary sewer line, which prevents the sensitive glass portion of the probe from becoming coated with grease, oil, and other contaminants, whereby the probe gives reliable pH indication over an extended period of time. The pH probe assembly utilizes a special filter media and a timed back-rinse feature for flushing clear surface contaminants of the filter. The flushing liquid is of a known pH and is utilized to check performance of the probe.

This report has been organized into three sections for ease of review. Section A - Air Resources covers data collected by the 100-foot tower between September and December 1980. Section B - Water Resources covers data collected since the last Quarterly Report. Section C - Aquatic Biology covers data collected since January 1981. Laboratory analysis results of all water samples show no significant changes from previous sample have occurred. The alluvial wells did exhibit slightly higher concentrations of phenols. Presently no baseline record exists for these wells to establish the normal levels of phenols in the alluvial ground water. Laboratory analysis of all sampling locations are presented in Appendix B. Aquatic biology covers data collected during the initial two aquatic biology field sampling trips of 1981. Benthic invertebrates, periphyton algae, and a fishery survey was conducted. Stream observations indicate that the stream habitat has remained unchanged since the August 1980 field visit. (ATT)
