Water and hydrology
Thaiwater WaterQuality API.
Best public multi-agency water-observation spine for latest station snapshots, timestamps, basin filters, and parameter values such as pH, dissolved oxygen, conductivity, turbidity, temperature, and salinity. Keep it separate from WQI batch publications.

Feeds active observations and signals that currently influence traveler-facing decisions.
How this helps travel recommendations
Turns water data into source-backed decisions about river condition, Bangkok tap-water confidence, raw-water salinity intrusion, beach caution, groundwater caveats, wastewater context, and whether a warning is really about tap, river, marine, or industrial water.

Developer reference
Use PCD and Thaiwater for river and station observations, MWA/PWA for tap or raw-water dashboards, DGR for wells, PCD/DMCR for marine and coastal sampling, and standards pages separately for interpretation rather than observation.
Refresh every 15-60 minutes, with caching and backoff when the upstream fails.

- There is no single all-water-quality Thailand API.
- WQI and MWQI are not realtime safe-today feeds.
- Tap water, raw water, groundwater, river water, marine water, wastewater, and industrial effluent use different thresholds and cadences.
- Satellite proxies such as chlorophyll or turbidity do not prove microbiological swim safety.
- Public industrial-effluent visibility is limited and often role-gated.
- The same station can appear under different agency names, IDs, and coordinate precision.

Source confidence: Treat this profile as strongest for the exact role named above. It is weaker when the source is stretched into live availability, legal proof, or traveler-fit decisions it does not directly prove.
