Water and hydrology

DMCR marine water quality.

Department of Marine and Coastal Resources publication layer for coastal and marine water-quality monitoring and explanatory context. Useful as a coastal-research and monitoring complement to PCD, not as a national realtime API.

Used in layers

page reference only

Useful fields

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

Reliability rating

Medium-high for discovery and context; operational reliability depends on endpoint stability.

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

Best endpoint

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.

Recommended refresh

Check weekly for change detection, but treat the official publication period as the real cadence.

Travel scoring role

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.

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.
