New York State Cooling Tower Locations and Legionella Test Results

Weekly self-reported data from the NYS Cooling Tower Registry details the location, operational status, and Legionella sampling results for cooling towers across New York State. Operators submit information including street address, city, zip code, and test results as mandated by Public Health Law. This snapshot is updated weekly and does not contain historical records.

Use Cases

• Predict high-risk areas for Legionella using `Equipment Last Legionella Test Result`, `Last_Sampled_Days`, and `County` for spatial clustering.
• Analyze compliance trends by correlating `Reg_Comp`, `CT_Status`, and `Equipment_Tower_Operation_Duration`.
• Map cooling tower density and proximity to vulnerable populations using `Latitude`, `Longitude`, and `School Districts 2016.shp 2`.
• Forecast inspection schedules by modeling `Last_Update_Days` and `Equipment Last Legionellla Sample Collection Date`.

Strengths

• Includes precise geospatial coordinates (`Latitude`, `Longitude`) for mapping.
• Contains key regulatory compliance fields (`Reg_Comp`, `CT_Status`).
• Data is updated weekly, providing current operational status.

Limitations

• Dataset is a weekly snapshot with no historical data for trend analysis.
• Data is self-reported, potentially introducing reporting bias or inaccuracies.
• Sample size and total row count are unknown.
