The purpose of the project is to identify the resources of drinking quality fresh underground water in the volume of 3000 m3/day in C1 category. The works are performed in the framework of a public contract in accordance with the program “Reproduction and use of natural resources”. “There are some long-standing drinking water problems in the region, the River Ustya is contaminated with industrial effluents, and the current water intake of the Oktyabrskiy village is located in the immediate vicinity to the border of distribution of brackish groundwater, so its operation involves the deterioration of the produced water quality, — said Constantine Firstov, the head of North-West PGA. — Considering the complex hydro-chemical conditions of the territory, our objective is to find a reliable supply of qualitative drinking water and resolve the problems of the district center.” The project works started in December 2019. Insofar, the specialists of RosGeo have completed the geophysical surveys by vertical electric sounding method at 280 points along the profiles with a total length of more than 26 linear kilometers. The analysis of the data obtained by the geophysicists enabled to explore the lithological composition and thickness of the quaternary and bed rocks, elaborate the geoelectrical cross-sections, perform the geological interpretation and correct the intended site locations of the exploration wells. The work area is strongly swamped and specified with a low passability for the drilling machinery, which complicates the work of the hydro-geologists. According to the results of exploratory drilling, the most promising areas will be identified for the second stage of the work — survey and qualitative and quantitative assessment of the groundwater in the aquifers. The completion of these works is expected in 2021.


RosGeo is a Russian multi-disciplinary geological holding that carries out a full range of services related to geological exploration: from regional surveys to parametric drilling and monitoring of subsoil conditions. The holding company boasts a unique expertise, particularly in marine geology and shelf operations. A total of more than 1,000 fields and deposits have been discovered by the holding’s companies, including major hydrocarbon and solid mineral deposits and fields. Rosgeo is a fully state-owned company.

North-West Mining Production Association, JSC (formerly Saint-Petersburg Comprehensive Geological Expedition; Sevzapgeologia JSC and Severkvartzsamotsvety JSC joined the Holding in 2017) performs all kinds of geological prospecting works for solid minerals and water resources: geological survey, prospecting and evaluation, explorations, field reconnaissance, hydrogeological and geo-environmental research.
