It has been revealed the exceeding of maximum permissible norm of Cu, Zn, Pb and Cd in the ponds, and the exceeding of maximum permissible norm of Pb and Cd in the canals of drainage system during the continuous time that certifies their permanent getting in the soils and waters from point and diffuse sources. The paper analyzes basic sources of heavy metals getting in the waters and their positive and negative impact on the biota. In order to increase ecological value of water objects and resources of agricultural lands it has been offered to use fertilizers and pesticides in a rational way, move to electric car use gradually, arrange landfills in a proper way, standardize algicidal fertilization, use fish fauna representatives to regulate number and algae biomass, equip the bioplateau and implement phytoremediation technologies with the aim to remove heavy metals from the soils and waters.177-187enpondscanals of drainage systemspollutantspermissible concentrationsArticle© Національний університет “Львівська політехніка”, 2022© Sukhodolska I., Krupko H., Portukhay O., Basaraba I., Kostiuk K., 202211doi.org/10.23939/ep2022.04.177Heavy metals concentration in the water of human-made objects / Iryna Sukhodolska, Halyna Krupko, Oksana Portukhay, Ilona Basaraba, Kateryna Kostiuk // Environmental Problems. — Lviv : Lviv Politechnic Publishing House, 2022. — Vol 7. — No 4. — P. 177–187.
