Key physicochemical parameters in volcanic soils post earthquake

Following the recent earthquakes, there are reports of surface water contamination. Given the locations, these are presumed to be natural contamination rather than due to extractive industries. Surface and rainwater are the main sources of potable water in the affected areas.

There is a lack of easily-accesible pre-earthquake physicochemical parameter tests, and multiple current annecdotal accounts of an oil-like veneer on the surface of water, and 'rotten egg' smell of hydrogen sulfide.

A partner is set to order a series of consumables for a range of tests: any experiences on what might be the key parameters to be looking for in such conditions?
