Water Quality Survey for Huron County, Michigan in 2004

A 2004 survey of water quality in Huron County, Michigan, conducted by the U.S. Geological Survey (USGS) in cooperation with the county. Samples were collected from the Pinnebog and Pigeon River watersheds from April through November for microbiological, chemical, and physical analysis. The work follows a prior USGS study from 1988-1990 that detected agricultural herbicides like atrazine in surface water.

Use Cases

• Analyze trends in agricultural herbicide contamination based on the detection of atrazine, metolachlor, and other pesticides mentioned in the description
• Assess nitrate-nitrogen and dissolved solids levels in river water based on historical monitoring data referenced for the Pigeon River
• Model spatial and temporal patterns of microbiological and chemical constituents based on the 2004 sampling campaign across two watersheds
• Evaluate the effectiveness of water quality policies based on the resolution passed by eleven townships calling for assessment

Strengths

• Data collection was conducted by the authoritative U.S. Geological Survey (USGS)
• Sampling occurred over an 8-month period (April through November 2004) for temporal coverage
• Analysis covers multiple contaminant types: microbiological, chemical, and physical constituents

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
