Water and hydrology
DIW water pollution monitoring.
Factory monitoring layer for parameters such as BOD, COD, flow, and related compliance signals in industrial contexts. Treat it as regulated operational infrastructure, not open national water-quality data.
Restricted
Online pollution monitoring system surface for industrial air and water pollution monitoring
System exists publicly on the web, but practical facility-level access is role-gated and not a public bulk feed
Operational / near real time where authorized
2026-05-11
Exists and matters, but direct operational access is limited to authorized users or agencies.
page reference only
waterbody, station, timestamp, parameter code, value, unit, method, quality flag, WQI/MWQI, salinity, pH, turbidity, DO, BOD, conductivity, residual chlorine, bacteria, heavy metals, source threshold
Medium-high for discovery and context; operational reliability depends on endpoint stability.

Not yet
No runtime entity scope yet.
No live observation ingestion yet.
Not wired into active decisions yet.
Profiled in the atlas and public pages, but not yet connected to live graph computation.
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.
Last checked and source confidence

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.
