The Yakima River Basin in Washington was assessed for contaminants in water, sediment, soil, and aquatic biota between 1987 and 1990. Samples from 26 individual locations and 32 stations composited into seven samples were analyzed for organochlorine pesticides, total PCBs, and semi-volatile organics. The assessment was conducted as part of the U.S. Geological Survey's National Water Quality Assessment Program.
Use Cases
- Analyze pesticide contamination trends based on organochlorine compound data
- Assess contaminant distribution across different environmental media (water, sediment, biota)
- Study the impact of agricultural runoff on river basin health based on trace-organic compound data
Strengths
- Data covers multiple environmental media: water, sediment, soil, and aquatic biota
- Samples collected from 26 individual locations and 32 stations over a 3-year period
- Analysis includes specific contaminants: organochlorine pesticides, total PCBs, and semi-volatile organics
Limitations
- Last updated 1990-11-30 23:59:59.999000; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- The method for determining total PCBs was not described in the report
