Groundwater is a valuable natural resource of fresh water and as such should be protected from deterioration and chemical pollution. The main groundwater chemical pollutants from agriculture sources are nitrates, plant protection products and biocidal products. In this manuscript the accent is given to the role of the plant protection products in the groundwater pollution. According to the European parliament and the Council’s Directive 2006/118/EC on the protection of groundwater against pollution and deterioration the threshold values set for pesticides in groundwater are 0.1 µg/l and 0.5 µg/l for total pesticides. Significant role in pesticide leaching in to the groundwater have their physical and chemical characteristics as well as the geological characteristics and ecological conditions in the region which contribute in differences regarding groundwater pollution in different regions. The usage of pesticides per hectare of agriculture land varies widely between European countries. Between 1985 and 1991, the usage was found to be the lowest in the Nordic countries, intermediate in Eastern Europe and highest in Southern and Western Europe. In Northern and Central European countries, the predominant type of pesticides used are herbicides, whereas in the Southern and Western countries are insecticides and fungicides. Herbicides such as triazines (atrazine, simazine, terbuthylazine, terbutryn, prometryn, propazine, cyanazine), phenylureas (chlortoluron, diuron, isoproturon and linuron) and anilides (acetochlor, alachlor, metolachlor), and insecticides such as organochlorine (lindane, DDTs) and organophosphorus (azinphos – ethyl, chlorpyrifos, chlorfenvinphos, dimethoate, fenitrothion, parathion - methyl and malathion) are the most common pesticides found in groundwater.
