摘要

This document presents the results of surface-water-quality data retrievals for Canyonlands National Park 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 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.
