Research on wet and dry pollution deposition was carried out at two measurement points situated on opposite sides of the Goczałkowice Reservoir. On the east side was a station in Goczałkowice and on the west side was a station in Frelichów. Meteorological monitoring was conducted at four points situated in the vicinity of the reservoir. On the basis of the research carried out between 2011–2013 it was concluded that the size of dry and wet deposition in the area of the Goczałkowice Reservoir is diversified in particular years, seasons and months. Due to high precipitation and biological processes (activity of flora and fauna) the pollutant loads in the form of biogenic compounds (nitrogen and phosphorus) are the highest in the summer season. Whereas pollutant inputs in the form of dry deposition are highest in the winter season (heating season), which in the case of a thick ice and snow cover in the spring time causes their accumulation and increased input into the reservoir water (thawing weather, snow-melt season). In relation to the 1970s the size of the deposition became smaller, but in the case of biogenic compounds it was diversified. A decrease was observed in the case of total nitrogen but an increase in the case of phosphorus. On the basis of a comparison of the received results with the data provided by the Provincial Inspector for Environmental Protection and calculated for the annual area deposition of the Pszczyna district in 2011 it appears that deposition of total nitrogen in the reservoir area slightly exceeded the area value. In the case of total phosphorus in relation to the area data the deposition was over twice as high, which indicates that biogenic compounds are still a significant load of atmospheric deposition in the reservoir area.
