Studies were conducted to determine the level of contamination of soil, ponds, water bodies and groundwater with biogenic elements in the territory of the settlements of Bolshiye Kovali and Aibash of the Vysokogorsky district of the Republic of Tatarstan. Observations were carried out at key field catchments taking into account the performed soil and water conservation measures (the village of Bolshiye Kovali) and without their implementation (the village of Aibash). It was found that the content of suspended solids in springs, ponds and reservoirs ranges from 0.0366 to 0.4674 mg/l. A high content of nitrate nitrogen (24.6 mg/l) was found in the springs of the village of Bolshiye Kovali, used for drinking purposes. Contamination of water bodies and springs with phosphorus was noted (exceeding MPC by 5-10 times). A high content of trace elements Cu and Zn was found in open water bodies. It is shown that the protection of open water bodies with earthen ramparts and forest belts reduces the contamination of water bodies with the colloidal fraction coming from arable land by surface water by 10 times. Anti-erosion measures, reducing erosion processes, accordingly reduce the contamination of water sources with biogenic elements.
