Baseline Water Quality Data Inventory and Analysis. Whiskeytown NationalRecreation Area. Volume 1 of 2

摘要

This document presents the results of surface-water-quality data retrievals forWhiskeytown National Recreation Area from six of the United States Environmental Protection Agency's (EPA) national databases: (1) Storage and Retrieval (STORET) water quality database management system; (2) River Reach File (RF3); (3) Industrial Facilities Discharge (IFD); (4) Drinking Water Supplies (DRINKS); (5) Flow Gages (GAGES); and (6) Water Impoundments (DAMS). The document provides (1) a complete inventory of all retrieved water quality data, water quality stations, and the entities responsible for data collection; (2) descriptive statistics and appropriate graphical plots of water quality data to characterizing annual and seasonal central tendencies and trends; (3) a comparison of the park's water quality data to relevant EPA and Water Resources Division water quality screening criteria; and (4) an Inventory Data Evaluation and Analysis to determine what NPS-75 'Level 1' water quality parameters have been collected in the park. The results of the retrievals for the study area from the IFD, DRINKS, GAGES, and DAMS databases located no industrial/municipal dischargers, three drinking water intakes, seven gaging stations, and two water impoundments. The results of the STORET retrieval for the study area yielded 71,773 observations for 275 separate parameters collected by one state agency and four federal agencies at 198 monitoring stations.
