Remote Water Quality Monitoring Network Data Report of Baseline Conditions for 2010/2011 A SUMMARY Susquehanna River Basin Commission Publication No. 280 Modified April 5, 2012 Abstract Approximately 85 percent of the collected at five-minute intervals and Susquehanna River Basin is underlain uploaded to SRBC’s public web site by shales containing natural gas, (mdw.srbc.net/remotewaterquality/) including the Marcellus shale at predetermined intervals via cell or formation.

The period of data collection for the 37 sites ranges from six to 18 months (Appendix B). Baseline data on these streams will assist SRBC and other agencies to detect if activities in the watershed are having an adverse effect on the water quality. Equipment and Parameters Each RWQMN station is comprised of the same equipment: data sonde, data platform, and solar panel or other power source. The data sonde is a multi-parameter SRBC staff installs data sonde at a station along Loyalsock Creek, Sullivan County, Pa. water quality sonde (see photo lower right) with an optical dissolved oxygen probe, an optical turbidity probe, a pH probe, and a conductance and will have elevated conductance graph, and determine basic statistics temperature probe.
