It is very important to carry out a risk assessment for the population in case of oral ingestion of active substances (DR) of pesticides with water. Objective. Hygienic evaluation of the persistence of pesticides in the soil recommended for the protection of berry and melon crops and prediction of the risk of groundwater contamination by them. Research materials and methods. Field studies, chromatographic method, mathematical modeling, calculation of SCI-GROW (screening of concentration in groundwater) and the risk of negative impact on the human body of the active substances due to leaching into the water (P). Results. DT50 indicators for phenhexamid and fludioxonil (Switch), glyphosate, spirodiclofen, abamectin less than 11 days (4th class), for fludioxonil (Kitch), cyprodinil within 11–30 days (3rd class), for boscalid, pyraclostrobin, pendimethalin, fluxapyroxad in the range of 33.26 – 53.92 (2nd class). Conclusions. For all active substances the value of risk the dangerous effect of pesticides on humans in case of their possible leaching from the soil into groundwater is acceptable.
