Analysis of the problems of high-quality drinking water extraction from underground water intakes on Vysotsky Island in the Vyborg district of the Leningrad region

Article preview

This article presents the results of drilling, experimental filtration work and laboratory studies aimed at assessing the resources and quality of groundwater in the licensed area of Vysotsky Island located in the Leningrad region, in the Gulf of Finland in accordance with the requirements of regulatory documents. Analysis of the results of hydrochemical studies and their comparison with data on water intakes in adjacent areas gives the right to conclude that it is possible to classify a hydrogeological unit as a different type of resource formation than those located in the surrounding areas. Groundwater in this area is confined to an unexplored deep fractured regional high-pressure zone. According to the received data, the explored water intake can be attributed to a unique groundwater deposit, which has an uncharacteristic composition of groundwater in the north of the Leningrad region, which may be due to the mixing of modern sediments and relict waters of the Baltic glacial lake. The stability of groundwater characteristics is confirmed by long-term monitoring.

Use of isotope data (δ2H, δ18O, 234U/238U) in the study of permafrost degradation processes as a result of long-term climate variations

Article preview

Marked warming of a climate has one of the results the degradation of a permafrost. Estimation of this degradation rates are necessary for considering at studying resources and qualities of underground waters, construction of long-term constructions, a burial place of radioactive waste, reconstruction of paleoclimate, etc. In this article it is considered theoretical bases and an opportunity of use developed by the author’s technique, which is based on isotope systematics δ 2 Н, δ 18 О, 234 U/ 238 U and U/He, 3 Н/ 3 Не dating of groundwater, and also correlations between them for reconstruction of rates of the permafrost degradation.

The use of isotope methods in the study of groundwater balance (Almeria, Spain)

Article preview

Hydrogeochemical and isotopic sampling of groundwater and surface water in the Almansora River basin was carried out in works on groundwater resources estimation in the province of Almeria (Spain). Surface and ground waters sampled in the Almansora River basin coincide with the general trend of atmospheric precipitation isotopic composition of the Mediterranean region, indicating an exclusively meteoric origin of ground and surface waters, the absence of significant isotopic fractionation after atmospheric precipitation, in particular due to evaporation. The insignificant role of transit flow in groundwater recharge within the hydrogeological unit of Auvers is shown.
