Groundwater quality testing in the area of municipal waste landfill sites in Dąbrowa Górnicza (southern Poland)

Abstract Groundwater quality assessment for pollution can be undertaken with the use of indicators that will confirm or deny negative impact potential sources. Based on water monitoring data from Lipówka I and II municipal landfill sites in Dąbrowa Górnicza last five years, area was assessed using Nemerow Pollution Index (NPI) method. Seven parameters were – pH, electrical conductivity, concentrations chlorides, sulphates, ammonium ions, boron iron. The limits class III used as reference level. results NPI calculations show highest indices obtained piezometers PZ5 T5 located outflow site. values index ions reached a value over 36 piezometer 17 piezometer. other did not indicate significant groundwater. observed 2017. It is worth noting that, apart large differences content conductivity specifically are twice high four times higher than boron. useful easy method assessing even small number parameters.
