Water and hydrology
MWA online tap-water quality.
Bangkok-metropolitan tap-water monitoring with residual chlorine, turbidity, conductivity, pH, chloride, and salinity across online stations. Strong for distribution quality within the MWA service area, not national tap-water coverage.

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.

curl -L "https://twqonline.mwa.co.th/EN"Failure modes
- 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.
- Dashboard markup or public-page layout can change without notice.

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.
