Use Cases

• Analyze seasonal water quality trends using Sample Date and Enterococci Results.
• Compare contamination levels across different Beach Name and Sample Location entries.
• Identify potential public health advisories by correlating high Enterococci Results with specific Sample Dates and Beach Name.
• Track sample collection and analysis metadata using Sample ID and Units or Notes.

Strengths

• Data is collected as part of an official public health monitoring program administered by the DOHMH Office of Public Health Engineering.
• Includes key variables for analysis: Sample Date, Beach Name, Sample Location, and Enterococci Results.
