Searching for an updated Resistivity Test to be used for Groundwater exploration.

Hello, I am searching for an updated Resistivity Test to be used for Groundwater exploration.

The groundwater exploration for detecting (i) availability of water bearing strata as well as (ii) chemical water quality of available water in the aquifer needs update on the following aspects :-
(a) Options / Methods and their user friendliness alongwith a comparative study scope of their use for detecting availability of a sustained aquifer and also the water quality (chemical), before one starts the boring.
(c) Authenticity of test results

Thanking you and waiting for your kind response.
Regards.
