A well on a map does not establish that its water is safe to drink. Check the well identity, location and lab results. Older records may not reflect current water quality or treatment needs.
Read the date and place on the test. Check what kind of water was tested and what the result means. A past test cannot tell you what is in the water here now. For a local warning, use the latest notice from the agency that covers the site.
Best public groundwater-well spine for consumption and agriculture wells, with related DGR quality datasets used separately for slower lab results. Historical quality does not equal present drinking safety.
Access: Smart Pasutara well portal and Open API endpoint for nationwide groundwater-well search. Updates: Monthly / on registry update for well master data.
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.
Access: PCD water-quality pages, publications, and linked national datasets for surface-water monitoring and WQI. Updates: Monthly / quarterly / annual depending dataset.
Representative automatic-station source for rivers such as Tha Chin, with parameters like temperature, pH, dissolved oxygen, and conductivity. Treat station coverage as partial, not nationwide realtime truth.
Access: Government Data Catalog dataset page with automatic-station resources and linked PCD catalog entry. Updates: Half-hourly observations at station level where resources remain current; catalog metadata on update.
Match any result to the named place, sample date, and type of water tested.
