Audit Methodology
Hydrolity publishes local water hardness reports using public utility data and standardized transformation rules. This page documents the core process so each page can be interpreted consistently.
Data Sources
- Municipal and regional water utility reports.
- Public environmental monitoring datasets.
- Open records from national and local agencies.
Normalization
Incoming records are normalized into a common structure by location (country, region, city, postal code), hardness value, and pH where available. Invalid or incomplete values are flagged and excluded from indexable pages.
Quality Controls
- Duplicate location checks per source cycle.
- Range validation for hardness and pH fields.
- Indexing safeguard: pages with missing core metrics are marked noindex.
