Reconstructive Techniques

An iconic story of recovery from nutrient pollution is the restoration of the heavily enriched Lake Washington in Seattle, Washington State. Originally an integral part of the municipal septic system, a diversion of wastewater in 1968 has allowed Lake Washington to return to what has been recently described as a natural and healthy state. Yet is it accurate to characterize a lake as “recovered” based purely on chemical measurements? Does a legacy of pollution linger on in the ecology of a lake system long after the lake has been given a clean bill of health?Using paleolimological reconstructive techniques it is possible to compare pre-pollution and post-pollution communities of algae by looking at microfossils stored chronologically in the lake-bottom sediment. Use of this technique has afforded a test of the assumption that once pollution stress in a lake is alleviated, the algal communities quickly return to the pre-pollution state. Work on Lake Washington indicates that this does not always hold true. Instead, it suggests that a legacy of pollution persists in the algae and ecological community of the lake long after the nutrient levels have returned to normal.

Rate Of Accumulation

Septic system plays a major role in sanitary disposal activities. In developing country it is very essential for proper disposal of wastes for providing clean environment. In our country the government has adopted scheme, “CLEAN INDIA”,. For achieving this aim, the septic system is necessary to construct in each and every residential, commercial buildings and public areas. Septic tank systems are a type of simple onsite sewage facility.But groundwater pollution may occur and can create a problem. Usage of mobile septic tank can be helpful to avoid such problem. In this present investigation an idea has been arrived and the septic tank constructed by the way which have been tested for 10 days for decomposition using microbes. The term ‘septic’ refer to the anaerobic bacteria environment that develops in the tanks which decomposes or mineralizes the water discharged into the tank. The rate of accumulation of sludge is faster than rate of decomposition. So in our project we have used microbes for decomposition.In urban areas, construction of septic tanks are easier. But in rock exposures, the septic tanks cannot be constructed easily. In this paper, the problem is solved by giving an idea as solution by providing a “MOBILE SEPTIC TANK”. This will be helpful and eliminate such problems.
