There is a concern that urban development and the construction and operation of highways in particular represent a substantial threat to groundwater quality in areas underlain by karst geology. The objective of this paper is to determine whether common stormwater treatment practices are effective at preventing adverse impacts. The Barton Springs portion of the Edwards Aquifer, a karst system in Central Texas, presents a unique opportunity to address this issue, in that stormwater treatment requirements have been in place over a period of 20 years, when a substantial amount of development, including new highways, has been undertaken. This paper analyzes water quality data from Barton Springs over this period to identify constituents that exhibit changes in concentration and identifies potential causes of these changes. This analysis indicates that the constituents for which water quality has exhibited degradation appear to be due mainly to increases in pumping for water supply and onsite disposal of wastewater. No changes in constituent concentrations were observed for those most closely associated with highway operation, including total suspended solids, heavy metals, pesticides, and bacteria. It was found that sand filters produce an effluent quality equal to or better than runoff from undeveloped land. Consequently, it can be concluded that sand filtration, or an equivalent treatment, is an effective strategy for preventing groundwater degradation from highway operation in karst terrains.

Origin Point

Urban development, agricultural runoff and industrialization have contributed pollution loading on the environment.  In this study Hemavathi river water from a stretch from its origin point to its sangama was studied for pollution load by determining parameters of water quality like pH, Alkalinity,  Ca, Mg, Nitrate, TDS, BOD, COD , and the results were compared with WHO and BIS standards to draw final conclusion on the quality of water.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.
