Impact of mountainous areas management system upon biogenes content in surface waters

nr 2

The paper presents the results of over 6 years research on biogenes concentrations in surface waters originated from 4 measurement and control sections located in the catchment of Trybska Rzeka stream, which is a right-bank tributary of Białka river whose mouth lies on the right shore of Czorsztyn reservoir. The research has been aimed at determining the impact of mountainous lands management system on the biogenes content in the surface waters flowing across the area. Since numerous factors, quite often difficult to identify, can influence the number of biogenes in water, the field studies were conducted in three very small catchments that were similar in terms of physical and geographical, as well as climatic conditions, but the lands differed in the agricultural management systems. An additional research section on Trybska Rzeka watercourse within the built-in area of Trybsz village has been established to determine the influence of village farmstead areas on biogenic contaminants introduced to surface waters via various agents. The conducted research allowed to conclude that the agricultural management system applied to microcatchments significantly impacts biogenes content in surface waters flowing out from the concerned area. Nitrate nitrogen and phosphates contents are most heavily impacted. It was also found that in mountainous areas grasslands are most effective in reducing nitrogen compounds content in infiltration waters. Settlement areas with inconsistent water and sewage disposal management systems and inappropriately designed facilities for storing sewage and manure contribute gravely to degenerating surface waters.
