NYC Drinking Water Tank Inspections and Audits Compliance Results
This is an official NYC Health Department dataset. The Health Department does not endorse datasets using these data that may be created by others. The dataset contains the drinking water tank oversight activity and compliance results for NYC buildings that have water tanks. The buildings listed have been reported to the NYC Health Department through the NYC Drinking Water Tank Inspection Reporting Site or were identified by the NYC Health Department during field observations. This dataset includes self-reported annual inspections (submitted by a certified water tank inspector on behalf of the building owner), NYC Health Department inspections, NYC Health Department audits, and other drinking water tank regulatory activity results.

Columns
Each source column, with the name and type we use to store it.
