Tytuł: Assessment of the variability of rainwater quality and the functioning of retention reservoirs in the urban area

Tytuł odmienny:

Ocena zmienności jakości wód opadowych i funkcjonowania zbiorników retencyjnych na terenie zurbanizowanym

Opis:

Three-year observations made it possible to assess the degree of pollution and variability in quality of rainwater collected in two reservoirs in the Lublin agglomeration (south-eastern Poland). The studied objects are characterised by different construction, size, hydraulics and type of drained surface. In particular, a large variation in water quality indicators was observed for suspended solids, NH4+, NO3- and K+. Higher conductivity, NH4+, SO4- and Cl- was found in the reservoir receiving rainwater from the national road, compared to the water from the housing estate. In the second reservoir, a higher load of NO2-, PO4-, Fe+ and K+ was observed. Among the analysed variables, the most disturbing values were recorded for conductivity, pH, suspended solids, oxygen indicators, NO2-, NH4+ and PO4-. The liquid flowing into the reservoirs during snowmelt was characterised by high pollution. In the year with the highest sum of atmospheric precipitation, there was a reduction in medium concentrations of many quality variables (flushing effect, dilution of pollutants). An increase in oxygen demand and oxygen deficits were observed in warm seasons. An emission of inconvenient odors in the vicinity of the reservoir in the housing estate was also observed. These phenomena may be intensified in the case of improper use of the system (e.g. when bottom sediments are not removed) and further increase of air temperatures. Under such conditions, the possibility of using open rainwater reservoirs near human settlements becomes questionable.
