Hi everybody,

I'm looking for surface water quality data for India. Intended purpose is a thematic map on state or district level, educational purpose. Does anybody have any leads as to where I can find data?

meant to say *surface* water

Thanks, but I had actually meant to say *surface* water, sorry about that.

Hans,

Water quality is also quite a complicated concept, with many aspects: BOD, chemicals, metals, pH, biochemical, suspended solids etc. And surface water is not so easy either - would it be measurements at stations that are interesting, the status of drainage basins. Measuring in lakes and rivers would be quite different. I might not sure what you are looking for, but making maps saying "here it is good, here it is bad" is not so easy/obvious - especially from the perspective of drinking water, since groundwater/precipitation can be used as well.

Googling turns up some stuff, that I am sure you can find too, which might be useful - I saw, among other things, a report with stats per drainage basin.

Here are some other assorted links, not checked for relevancy...

Hans, you might use watersheds (hydrological drainage area) as your mapping unit, and rate them by the average level.

To put it into perspective, you might use India's water quality objectives but if you have too much trouble getting these, you could use some more universal levels, especially for physical and chemical properties (BOD, turbidity, pH, temperature, electrical conductivity).

Good luck with the data hunt! :D
