Ground water samples from Cooum belt areas were collected and analyzed for their physico-chemical characteristics. Results obtained were inferred based on the drinking water quality standards of IS 10500:1991. Out of the ten locations chosen, Anna Nagar and Pachayappas were found to possess high total dissolved solids values. Nitrate was found higher in ground water drawn from sources of Fort St. George and Pachayappas. Possibility of pollution of ground water resources in Cooum belt areas is indicated by the study.Keywords

This paper deals with the technique to stabilize the black cotton soil for the construction of road by using fly ash. Construction of road in a black cotton soil is a challenging task in the civil engineering field. Excessive heaves associated with swelling of expansive soil can cause considerable distress to lightweight civil engineering structures. When the B.C. soil comes in contact with the moisture, it shows considerable volumetric changes. Due to this type of phenomenon, many problems associated regarding maintenance and economic life of the highway and roadway. An attempt is made here to find out solution by using fly ash, which is a by-product of thermal power station. Fly ash becomes a main concern of worry because of its disposal problems and hazardous nature. Use of fly ash in an expansive soil gives economical and ecological solution for stabilization of sub grade of road embankment. So it is a case of “Churning waste into wealth and turning ash into cash”. Experimental works have been carried out in a laboratory, which shows that fly ash improves various engineering properties of the expansive soil like liquid limit, plastic limit, plasticity index, swelling pressure, swelling index, shear strength etc. Investigation says that fly ash is a good stabilizing agent for the construction of road in the black cotton soil.Keywords
