Surface Water Runoff

Construction site soils are a significant source of sediment, and pollutants carried by sediment, to surface water runoff. Currently, silt fences/barriers, petroleum-derived polymers, and re-vegetation are the primary tools to prevent sediment loss from construction areas. Even with these methods in place, the U. S. Environmental Protection Agency estimates that 20 to 150 tons of soil per acre is lost to storm water runoff from construction sites each year. A low-cost, environmentally friendly soil amendment that reduces erosion from construction sites would improve surface water quality. An extracellular polymeric substance (EPS) is produced naturally by the symbiotic soil bacterium Rhizobium tropici. A dry, easily transportable salt of this biopolymer, when mixed with soil at low levels (0.01 to 0.5% by mass) substantially increases the soil strength for load bearing, decreases surface erosion and suspended solids in surface water runoff. Re-vegetation is also assisted by biopolymer application, since drought resistance and seed germination rates can be increased by 30% to 40% using the biopolymer. Results of mesoscale rainfall lysimeter system demonstrations of soil amendment with biopolymer documents reduced soil erosion, reduced transport of suspended solids in surface water runoff, and increased establishment success of vegetative cover under simulated drought conditions in biopolymer amended soils.

Abstract The objective of the study was to assess the quality of the Shule River water for irrigational purposes. Surface water samples were collected along the course of the river in May and October 2012. The samples were analyzed for pH, electrical conductivity (EC), bicarbonate, chloride, sulphate, sodium, potassium, calcium and magnesium. Surface water was generally alkaline (average pH 8.17) and water pH and total dissolved solids in May were higher than those in October. EC ranged from 0.24 to 2.15 mS cm−1. Sodium was identified as the dominant cation, sulphate was identified as the dominant anion in May for both samples of river water but, in October, the dominant anions are respectively sulphate, bicarbonate and chloride from the upper region to the lower region. The total dissolved solids, chloride and sodium were found to exceed the permissible limits for irrigation water in the lower region. According to the principal factor analysis results, among water quality parameters measured in this study, chloride is the best indicator for monitoring water quality. The results revealed a deteriorating water quality in the lower region of the river.
