EVALUATING ACQUIESCENCE OF FLEXIBLE REMEDIATION EXPERIMENTAL DESIGN SUSTAINING LAKE WATER RESOURCE QUALITY.

The non-point source pollution (NPS) happens when water budges pollutants from the land towards the water bodies. The sediments and nutrients are recognized as the most common such (NPS) pollutants and when released into the receiving waters as a result of soil erosion can become NPS pollution. Soil erosion is a major issue and efforts to reduce the impacts of various activities on sedimentation are the essence of the moment. Once the cause is determined, a low-cost, innovative solution should be thought of. Various compost filters have been experimented, however, Eicchornia leaf biomass filters are not yet reported to have been employed for the purpose. The rationale of the study was to estimate effectiveness of Eicchornia leaf biomass filter sleeves as a sediment barrier at the lake waters. Eicchornia leaf filter sleeves (Sun dried premature Eicchornia leaf biomass fills) crammed in an IS 16008 (2012)- tubular mesh sleeve as a linear land based treatment filter were investigated by us earlier and the results have been published. The earlier studies depicted effective percent reduction of sand 89%, TSS 68%, silt 56%, turbidity 51%, and clay by 18%. As a part of extended study, the serrated model was employed and it resulted in percent reduction of sand 90%, TSS 72%, silt 69%, turbidity 62%, and clay by 28%. The serrate based application of the sleeve did not show any significant increase in the sand filtration in comparison with the linear based model. The serrate based model resulted in a increase in the percent reduction of total suspended solids, slit, turbidity and comparatively more of clay. The probable reason confirmed is due to the increase in the runoff slope length. Thus it can be concluded that the serrate mode of application of Eicchornia biomass sleeve is more effective in comparison with the earlier linear based model. However we arrive at a conclusion that the selection and application of the linear based or serrate based Eicchornia biomass sleeves should be site specific. Either of the methods indicates a promising reduction in the silt loads into the lake waters. The Eicchornia biomass sleeve application should emerge as a novel, cost effective, and environmentally friendly method of silt filtration. This serves twofold function one to eradicate the notorious weed and to diminish soil erosion and habitat destruction to protect sensitive wetlands, water bodies, wildlife habitat, and ecosystems in a paramount environmental friendly approach. In continuation to the earlier studies it is anticipated that by studying the processes of erosion and sedimentation, innovative sediment control and management attempts provide examples of effective erosion and sediment control strategies. Such attempts should support to plan and implement at the lakes aiding conservation and restoration activities for sustainable environment.
