Lead Levels in Delaware Public School Drinking Water

Lead concentration measurements from water samples collected at consumption and non-consumption points in public schools. The dataset includes results, sampling dates, and school district information, published by data.delaware.gov and last updated in January 2023.

Use Cases

• Identify schools with `Result` values exceeding the `MCL` (Maximum Contaminant Level) for lead.
• Analyze temporal trends in lead levels by grouping samples by `Sample Date` and `District`.
• Compare lead contamination between `Consumption Point` and `Sample Point` types across different schools.
• Assess compliance monitoring by tracking the `Additional Sampling Completed` status following initial detections.

Strengths

• Contains 11 distinct data columns including `Result`, `MCL`, and `Sample Date`.
• Data is provided in multiple machine-readable formats (CSV, JSON, XML, RDF).

Limitations

• Unknown total number of samples (`Rows`) and file size.
• Sample data is unavailable for previewing data distribution and value ranges.
• Geographic coverage is limited to the state of Delaware.
