The points of the national network of groundwater monitoring comprise a stable benchmarks in quality and quantity monitoring. The obtained data (tritium and δ18O) are important for understanding the groundwater cycling and are indirect indicators of aquifer vulnerability to anthropogenic pollution. The goal of this paper is to present the relation of the tritium content and delta value of stable isotopes of oxygen against the groundwater sampling depth in 2004–2012. It is demonstrated that the remains of “nuclear” tritium concentration is still present in groundwater as a tritium peak at depths around 30 m. Determination of dynamics of recharge in groundwater bodies, based on national network observation points is associated to the estimation of the groundwater residence time in aquifers and remains one the vital problem of hydrogeology.

The paper deals with the problem of anthropogenic changes in the extent of peat deposits, their volume and water retention capacity of raised and valley peat bogs in the Polish part of the Orava-Nowy Targ Basin and the Bieszczady Mts. This problem has not received a great deal of attention in the research literature. Special attention was paid to the remnants of peat domes and post-peat areas. The decrease in the area of peat bogs, the volume of peat deposit and the quantity of water retained within them were estimated for the last ca. 400 years. This paper is based on an analysis of maps produced over the last 230 years as well as aerial photographs. Field data and laboratory data were also analyzed as part of this research.
