9 Water monitoring systemThe local monitoring system for water quality around the <strong>landfill</strong> consists of (Fig. 3):- 17 observation points in the first groundwater layer (shallow piezometric wells),- 6 observation points in the second (drinking) water-bearing layer (deep piezometric wells),- 7 farm open wells selected in the villages of <strong>Lubna</strong>, Baniocha and Szymanów,- 7 sampling points situated at surface water courses (ditches),- 1 sampling point of ‘raw’ leachates (from peripheral drainage well, before the leachatetreatment plant).This network enables the proper assessment and estimation of water quality in the vicinity of the<strong>Lubna</strong> <strong>landfill</strong>. Analyses of surface water and groundwater located in the surroundings of the<strong>landfill</strong> have been carried out since 1994, whereas chemical analyses of ‘raw’ leachates from theperipheral drainage - since 1998. Measurements of the water level in piezometric wells areconducted every month and are used to define the directions of groundwater flow (Fig. 29) andmigration of pollutants. Groundwater samples were collected with special equipment (Fig. 30).The water quality is analysed twice a year. Annual repports are prepared for the environmentalprotection authority and for the local population.FIG. 29 Flow directions in the 1 st groundwater level in the surroundings of the <strong>Lubna</strong> <strong>landfill</strong>22
