Baseline Water Quality Data Inventory and Analysis: Buck Island Reef National211 Monument, Christiansted National Historic Site, and Salt River Bay National 211 Historical Park and Ecological Preserve

摘要

This document presents the results of surface-water-quality data retrievals for211u001eAztec Pulps National Monument from six of the United States Environmental 211u001eProtection Agency's (EPA) national databases: (1) Storage and Retrieval (STORET) 211u001ewater quality database management system; (2) River Reach File (RF3); (3) 211u001eIndustrial Facilities Discharge (IFD); (4) Drinking Water Supplies (DRINKS); (5) 211u001eFlow Gages (GAGES); and (6) Water Impoundments (DAMS). The document provides: (1) 211u001ea complete inventory of all retrieved water quality data, water quality stations, 211u001eand the entities responsible for data collection; (2) descriptive statistics and 211u001eappropriate graphical plots of water quality data characterizing annual and 211u001eseasonal central tendencies and trends; (3) a comparison of the park's water 211u001equality data to relevant EPA and Water Resources Division water quality screening 211u001ecritera; and (4) an Inventory Data Evaluation and Analysis to determine what NPS-211u001e75 'Level 1' water quality parameters have been collected in the park. 211u001eAccompanying the report are disks containing digital copies of all data used in 211u001ethe report, as well as all components of the report (tables, figures, etc.). 211u001eInformation suitable for import into a GIS is included. The results of the 211u001eretrievals for the study area from the IFD, DRINKS, GAGES, and DAMS databases 211u001elocated no industrial/municipal dischargers, drinking water intakes, water gages, 211u001eor water impoundments. The results of the STORET retrieval for the study area 211u001eyielded 23,502 observations for 60 separate parameters collected by the NPS and 211u001eEPA at 129 monitoring stations from 1968 through 1996.
