Schuylkill River at Philadelphia, PA - 01474500

Important information about this monitoring location

Calibration of specific conductance, dissolved oxygen, and pH instrumentation is conducted exclusively by Philadelphia Water Department personnel with USGS oversight. Erroneous or missing data, resulting from instrument malfunction, are not the responsibility of USGS. The 30-minute precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
