Geoecological characteristics and assessment of the impact of the construction of the Murmansk transport hub on the spring «Domashny»
Abstract
Based on the data of the study of springs in Murmansk and its suburbs, conducted from March 2014 to March 2019, the characteristic of the chemical composition and quality of spring waters is obtained. The water object considered in the article is located on the territory of the Kola district of the Murmansk region, in the immediate vicinity of which the construction of a road junction of the Murmansk transport hub is currently taking place. Given geoecological estimation of conditions of formation of spring water in settlement Prichalnoein the Kola district of the Murmansk region. On the basis of long- term observations the formula Kurlova for this spring is made. The ecological and chemical state of the spring was assessed by the following indicators: odor, chromaticity, hydrogen index (pH), chlorides, sulfates, phosphate ions, nitrite ions, nitrate ions, permanganate oxidability (POC), total alkalinity, hardness, total iron, calcium, aluminum, mercury, molybdenum, copper, strontium, nickel. The study found that the ionic composition of spring water is mainly influenced by natural factors – rocks that make up the catchment areas, and climatic features of the region. Increasing concentrations of pollutants in the spring water are observed in the spring and autumn periods and are due to the infiltration nature of spring waters. The influence of drilling and blasting operations on the composition of spring water was not revealed.
