Thank you for all your ...

Thank you for all your answers. To give you a bit of background, I am working in a relatively large pre-alpine catchment (~2000 Km2) with predominantly agricultural landuse in the upper reaches of the catchment , and urban as well as industrial landuse types in the lower reaches. I am trying to find out whether there is any best practice protocol, paper, etc. for ground and surface water quality parameters which should be measured in order to characterize and monitor the catchment processes. There are plans to rehabilitate certain sections of the primary river to improve groundwater infiltration, but otherwise its "business as usual. Thanks in advance for all your responses.
