Thailand River Water Quality.
PCD WQI, automatic stations, Thaiwater observations, and river-condition context for Thailand surface-water monitoring.
BMA canal water quality
Bangkok canal and Chao Phraya urban water-quality layer for WQI, BOD, dissolved oxygen, ammonia, and station context. It is useful for city trend pages but not a universal realtime swim-safety feed.
Bangkok open-data dataset with WQI records and related Chao Phraya/canal monitoring context Water and hydrologyMRC Mekong water quality
Best transboundary Mekong water-quality context for monthly monitoring, nutrients, solids, oxygen, and incident follow-up. Keep basin-scale monitoring separate from local Thai drinking-water claims.
Official monitoring programme pages, reports, and linked data or download surfaces Water and hydrologyMWA raw-water salinity
Best public MWA layer for Chao Phraya raw-water salinity intrusion and intake-quality monitoring. Raw-water intake quality is not the same thing as finished tap-water quality.
Public raw-water remote monitoring dashboard for salinity, conductivity, pH, dissolved oxygen, TDS, and related intake surveillance Water and hydrologyPCD automatic water quality stations
Representative automatic-station layer for rivers such as Tha Chin, with parameters like temperature, pH, dissolved oxygen, and conductivity. Treat station coverage as partial, not nationwide realtime truth.
Government Data Catalog dataset page with automatic-station resources and linked PCD catalog entry Water and hydrologyPCD marine water quality
Primary official marine/coastal quality layer for Thailand MWQI and sampling-round context. Good for coastal status and pollution hotspots, not for same-day beach bacteria guarantees.
PCD marine/coastal water-quality pages, MWQI summaries, and linked statistics/publications Water and hydrologyPollution Control Department water quality
Primary official source for Thailand surface-water quality, WQI, and public water-quality service guidance. Use it for national river and lake status, not as a universal realtime API.
PCD water-quality pages, publications, and linked national datasets for surface-water monitoring and WQI Water and hydrologyThaiwater 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.
