The article presents the results of research of the chemical composition of the liquid phase of snow along the entire length (source, intermediate point, mouth) of the small Khodtsa River flowing in the Moscow region during winter low water. A quantitative chemical analysis of the components of the liquid phase of snow was carried out along the entire length (source, intermediate point, mouth) of the small Khodtsa River flowing in the Moscow region during winter low water. The Khodtsa River is a receiver of wastewater from the industrial site of PJSC “Machine-Building Plant” (Elektrostal). In melted snow water, the values of the hydrogen index, the content of dry residue, aluminum, permanganate oxidation, ammonia nitrogen, iron, cadmium, lead and petroleum products were determined. It was shown that most of the determined indicators correspond to established quality standards, however, permanganate oxidation in the selected samples was quite elevated, which may indicate the presence of organic pollutants.
