Reservoir mapping
Selection of techniques to receive data and information 
to draw maps of water reservoirs.


One proactive measure to protect vital groundwater
resources is reservoir mapping. An important first step
is to conduct a survey of existing wells and then identify
and map potential sources of contamination, such as poorly
functioning septic tanks, manure leaching into groundwater,
and informal dumps. If possible, another key piece of information
to collect is the location of groundwater recharge areas.
With groundwater information, the community can develop
and implement a plan of action. Groundwater Vulnerability
maps aid informed judgements on issues where groundwater
impacts may occur e.g. new developments. Important elements
of groundwater maps are:

- delineation of the source water protection area,
- inventories of potential contamination sources, and

- determinations of susceptibility of the drinking water
supply to contamination.
