PurityMap provides informational and educational content only.

The information published on this website is intended to help users understand publicly available water quality data and related topics. It is not a substitute for professional advice or services.

This disclaimer applies to all content on PurityMap, including city reports, contaminant explanations, scoring systems, and filtration references.

General Information Disclaimer

PurityMap does not provide professional services of any kind.

The content on this site is not intended to replace or substitute:

  • Medical advice or diagnosis
  • Public health guidance
  • Environmental or laboratory water testing
  • Plumbing or water treatment consultation

All information is provided “as is” for general awareness and decision support only.

Not Medical or Health Advice

PurityMap does not provide medical, clinical, or health advice.

Any references to potential health effects, risks, or outcomes related to water contaminants are:

  • Based on publicly available scientific and regulatory research
  • Presented for general educational purposes
  • Not intended as medical guidance, diagnosis, or treatment

If you have health concerns, symptoms, or specific medical conditions, consult a qualified healthcare professional.

For details on how health context is evaluated, see our Methodology & Data Sources page.

Water Quality Data Limitations

PurityMap relies on publicly available data from federal, state, and municipal sources.

Important limitations of this data include:

  • Reported values reflect utility-level monitoring, not real-time household testing
  • System-wide averages may not represent individual homes or buildings
  • Household plumbing, fixtures, and internal pipes are not evaluated
  • Data may be incomplete, delayed, or periodically updated

PurityMap does not conduct on-site testing, laboratory analysis, or direct water sampling.

Local reports should be viewed as a starting point for understanding potential water quality conditions.

You can explore how this data is used in our City Water Quality Reports.

Regulatory Standards vs Health-Based Guidelines

PurityMap may reference multiple types of benchmarks, including:

  • Regulatory limits set by government agencies
  • Health-based guidelines and advisories
  • Independent scientific or environmental benchmarks

These standards serve different purposes and should not be interpreted interchangeably.

Meeting regulatory requirements does not necessarily indicate optimal health conditions. Likewise, exceeding advisory benchmarks does not imply immediate danger.

PurityMap does not declare water unsafe unless explicitly stated by relevant regulatory authorities.
