Groundwater interaction assessment based on the large-scale mapping of geological and hydrogeological conditions in Moscow

Assessing the interaction between aquifers is crucial for estimating the extent of protection of the aquifer in Carboniferous limestone (which is the main source of potable water supply to Moscow area) against contaminants penetrating from the overlying aquifers. The presented approach to assessing groundwater interaction and protection is based on large-scale mapping of the geological and hydrogeological conditions in Moscow. The obtained results may be used for solving the problem of groundwater protection against contamination, as well as for planning the engineering activities in the city.
