Abstract Water intended for human consumption (whether natural or after applying appropriate treatment techniques) must comply with the values of quality parameters according to the laws and regulations in force. The geographical area analysed in this study covers part of Dambovita County and lies at the contact between the Outer Subcarpathian Hills at the Curvature and Candesti Piedmont, the High Plain of Targoviste and Titu Subsidence Plain. Considering that the population in this area is also supplied with water from individual wells, which capture surface aquifers, changes in some potability parameters may appear punctually, inducing a number of health impairments if consumed over a long period of time. 12 sample points have been chosen in localities considered to be vulnerable and a number of parameters (pH, Ca2+, Cl-) have been analysed in the laboratory. Analyses have revealed excessive MAC (Maximum Allowable Concentration) in some locations such as Glodeni and Gheboaia.

Black earths and Australian brown earths occur in ways contrary to normal expectation in the red brown earth zone of southern Australia. The soil pattern is an intimate fine-grained mosaic of the three great soil groups changing within a few yards from one to another in an erosional landscape and quite out of accord with the underlying Precambrian metamorphic rocks. Field studies reported here ascribe the black earths to thin intermittent remnants of a lacustrine Tertiary clay as parent material, and the brown earths to a mixture of the clay with the normal weathering products of the underlying rocks. A substantial part of the evidence for this is derived from their distribution as a horizontal lamina tracing out a contour band in the mid and upper mid slope topography. There is a nice accordance between the elevations of this band and of an adjacent, elevated, dissected black clay plain. The three soils are everywhere found in places which are consistent with the postulate that their parent materials were put there by processes of erosion, dissection, and redistribution of distinctly separate hill and high plain landscapes.
