Organ Pipe Cactus National Monument Water Quality GIS Layers

Small-scale GIS data layers compiled by the National Park Service for a Baseline Water Quality Data Inventory and Analysis Report. The layers depict locations of water quality monitoring stations, industrial discharges, drinking intakes, water gages, and water impoundments. Data sources include EPA databases like STORET and RF3 Hydrography.

Use Cases

• Map water quality monitoring station locations based on the EPA STORET database
• Analyze proximity of industrial discharges to park boundaries based on the Industrial Facilities Discharges layer
• Identify drinking water supply intakes near the park based on the Drinking Water Supplies data
• Create hydrography overlays for park management based on the River Reach File (RF3) Hydrography layer
• Assess water impoundment impacts on park hydrology based on the Water Impoundments layer

Strengths

• Data compiled from six authoritative EPA national databases, including STORET and RF3 Hydrography
• Layers include roads, hydrography, political boundaries, and hydrologic units at a scale generally of 1:100,000
• Created for a specific Baseline Water Quality Data Inventory and Analysis Report for Organ Pipe Cactus National Monument

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• The scales and specific layers included vary depending on data source availability
• Row count is unknown, which may limit suitability assessment
