Groundwater is our main source of drinking water and thus monitoring its status is greatly significant. The status of groundwater shall be kept as close to the natural status as possible.

On the basis of main groundwater levels, 39 bodies of ground water have been distinguished; their status is evaluated by several qualitative indicators.

The status of the groundwater body of the Ordovician oil shale basin is bad due to the occurrence of  heightened amount of sulphates, their mineral and rough quality, as well as dangerous substances (above all, phenols).

In addition to Ida-Viru County, groundwater pollution of limited extent or the deterioration of its quality occurs mainly in Silurian-Ordovician groundwater bodies with unprotected groundwater all over Estonia.

The qualitative general status of all other groundwater bodies in Estonia may be considered good.
