Evaluation of a peat filtration system for treating highway runoff in a karst setting, 2003,

The deleterious character of highway runoff, especially following long periods without precipitation, has been well documented in the literature. It transports hydrocarbons, heavy metals, and other contaminants from highways, contributing to the pollution of surface water and groundwater. Groundwater is particularly vulnerable in karst areas where highway runoff is transferred quickly into subsurface conduit networks through open sinkholes and/or sinking streams. The difficulties in remediating contaminated karst aquifers make it crucial for karst aquifers to receive only uncontaminated water. A peat filtration system was constructed at the I-40/I-640 interchange in eastern Knoxville, Tennessee, USA, to remove highway runoff contaminants prior to being transported into karst aquifers.- Recent field tests indicate that the system can significantly decrease the concentrations of analyzed constituents including PAHs (polyaromatic hydrocarbons), popper, and zinc. However, the removal efficiency depends on the concentration of the contaminants in the runoff. Long-term monitoring is required to determine the true effectiveness of the designed filtration system and its reliability

Organic pollutants in stream sediments of Kupa River drainage basin, 2005,

This paper presents the first results of distribution of organic pollutants in 44 sediment samples (fraction < 63 mu m) of Kupa River drainage basin, which is a significant water resource for Croatia, Slovenia and BiH (Bosnia and Herzegovina). The investigated region aimed to be used as a model for future studies, necessary to meet Decision No. 2455/2001/EC. Some parts of the drainage basin are national parks (Risnjak and Plitvice Lakes). Also, a great part was affected by war 1991-1995 and is still under mines, what makes it difficult to sample. Sediments have shown a good record of pollution. Concentrations of total polychlorinated biphenyls (PCBs) were found above toxic levels (> 0.02 ppm) for 7 sediment samples. Total phenols were determined above 0.65 ppm for 23 sediment samples, which was characterized as heavily polluted sites. Mineral oils above 100 ppm were found in 13 sediment samples, which are, therefore, moderately polluted. Total lindane isomers in all sediments were below the detection limit of 0.0004 ppm, and, therefore, far below the toxic level of 0.0009 ppm. Results have shown unexpectedly that the western part of Kupa River drainage basin, with karst aquifers of high risk located in the boarder area of Croatia and Slovenia, has sediments, which were more polluted with organic contaminants from those affected by the war in the middle and eastern part of the basin. Further studies of sediments and protection of karst aquifers in this region is suggested
