A practical guide to geostatistical mapping

My work as an environmental science consultant, ... means that all data
available to me are generated by regulatory requirements, not by the needs
for a research project. And, the overwhelming number involve aquatic
chemistry (and biota such as fish) which adds the constant movement of the
medium into consideration.

I did two web searches this morning, one for 'aquatic geochemistry' the
other for 'water quality geochemistry'. They both returned many hits on
soils and ground waters, but only two related to surface waters.

   There is a need to improve on this.

   If anyone knows of documentation relevant to surface water quality,
particularly flowing waters, please point me to them.

Regards,

Rich
