GRSM_WQ: Great Smoky Mountains National Park Water Quality Survey, 1993-2025

Water quality survey data from the Great Smoky Mountains National Park, collected from 1993 to 2025. The dataset is organized by the National Park Service and includes five tables covering project descriptions, monitoring locations, and results for field measurements and lab analyses. Data is filtered to include accepted or certified results from the GRSM_WQ project.

Use Cases

• Analyze long-term trends in water chemistry based on the 32-year period of record mentioned in the description
• Map and compare water quality parameters across different monitoring stations within the national park
• Study the relationship between hydrological units and water characteristics using the provided HUC and Characteristics tables

Strengths

• Data covers a 32-year period from 1993-10-01 to 2025-11-22
• Includes quality-controlled results filtered to 'Accepted', 'Certified', or 'Final' status
• Structured into five relational tables (Projects, Locations, Results, HUC, Characteristics) for organized analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
