Abstract
The objective of this paper was to identify possible specific contamination of stormwater biosolids, with a special emphasis on pollution associated with transportation of municipal solid wastes to the waste utilization plant. The study area for sampling includes two selected points of separate stormwater collection system in Cracow. Samples of stormwater and biosolids were collected during spring-summer-autumn season addressed towards rainy days to check the scope of the problem The results led to conclusion, whether the waste utilization plant impacts the stormwater quality, compared to the high-traffic road. The largest pollutants found in stormwater near the plant were nutrients (nitrogen, phosphorus) however general content of organic matter in biosolids collected in separated stormwater system also confirmed adverse impact of solid waste transportation on stormwater sludge (biosolids) quality.
Highlights
Constant increase of impervious land cover in municipal areas during the last few decades has led to the increase in stormwater volume to be handled by municipalities
Common stormwater pollutants originating from anthropogenic practices include hydrocarbons and surfactants, metals, insecticides, herbicides, pharmaceuticals and personal care products, organic matter, nutrients, sewage, and litter [1,2]
The road with the catch basin no. 2 is exposed to contamination related to transportation of municipal solid wastes to the plant primarily by heavy-duty dumper trucks
Summary
Constant increase of impervious land cover in municipal areas during the last few decades has led to the increase in stormwater volume to be handled by municipalities. The a range of pollutants include: the layout of drainage infrastructure, road and building materials used, the range of transport systems and traffic density, the percentage of impervious surfaces, human behaviour, and waste disposal practices. Common stormwater pollutants originating from anthropogenic practices include hydrocarbons and surfactants, metals, insecticides, herbicides, pharmaceuticals and personal care products, organic matter, nutrients, sewage, and litter [1,2]. Sediments originating from anthropogenic activities bind with pollutants and act as a mobile substrate in transport of these pollutants into receiving waters.
