Abstract:	The paper presents the results of studies on the influence of wastewaters discharged from the sewage treatment plant in Międzyrzec Podlaski on water quality of the Krzna River. Based on the results of measurements of selected chemical parameters of water and biological indices based on macroinvertebrate taxonomic composition it was found that the influx of wastewaters from the sewage treatment plant lowers the values of chemical indices of water, increases the density of macrofauna, especially of Oligochaeta and Erpobdellidae, lowers the number of macroinvertebrate families and the value of the BMWP-PL index. The quality of the Krzna River water improves significantly 5 km downstream the outlet of wastewaters from the sewage treatment plant.
