Subhashini3 (M.tech), Assistant Professor of Civil Department, Saveetha University, Chennai Abstract: As the water is the major source of litres a day by the Alanthur municipality sewage earth, still people refuses to use the nature’s water plant made it to be completely polluted. In creation in the correct way. Pallikaranai addition wastes generated from the city areas and wetland–earlier it was the fresh water body in the the industrial wastes were dumped exactly at the Chennai city, later on it has been deteriorated sewage letting point. Nearly 250 acres of the and the nature of the wet land has been land was completely dumped by the city garbage eradicated by the human activities which wastes. Around 1500 tonnes of wastes were put includes the dumping of waste into the land, into the Pallikaranai wetland daily. Then this poisonous solids, sewage discharge, construction marshland had become the largest dump land. of many buildings, etc,. Henceforth, here the All these leaded to the reduction of fauna paper flashes about the quality test of the water population of the Pallikaranai wetland. in an around Pallikaranai wetland to test whether the water is eligible 1.2.1 Protection efforts Keywords: The Tamilnadu pollution control board has taken some steps to control the pollution of the Pallikaranai wetland, deterioration, quality test.

LITERATURE SURVEY Due to huge construction work undertaken by the government and few private companies made the The study of different types of lakes and its Pallikaranai wetland to face the initial stage of qualities was studied. This study flashes out the pollution but that wasn’t the end. Again a huge different results and the comparisons of those release of untreated sewage water of 32 million values with all the water quality standards. Few 4757 International Journal of Pure and Applied Mathematics Special Issue point sources and non point sources were different points and the intervals, and then taken investigated. As the result, all the values were to the laboratory. mostly of under or above the good qualities. Still few of them were quite ok at its level. 3. MATERIAL AND METHODS 3.1 STUDY AREA Pallikaranai marshland is located near the Coromandel Coast at the souther side of the P 1 Adyar estuary. It’s surrounded by the road way of old Mahabalipuram & many residential living P2 areas which are Madiakkam, Velechery, etc., and its catchment area is nearly 235 square P3 kilometres. Its maximum length is 15 km, P4 maximum width is 3 km, surface area is 80 P8 square kilometre, water volume is 9 cubic P7 kilometre, surface evaluation is 5 meter and its P5 P6 coordinates 12°56′15.72″N, 80°12′55.08″E.

Then they are transported to the PA_SED 4 12.95136 80.21160 laboratory and kept in the normal temperature. Proceeding further, different types of water PA_SED 5 12.94890 80.21078 quality tests are done. PA_SED 6 3.3.1 pH, Electrical conductivity 12.94871 80.21209 pH indicates the hydrogen ion concentration in PA_SED 7 water and it ranges from 0-14 where as 7 is 12.95906 80.21578 neutral, less than 7 is acidic and more than 7 is basic. Then there comes the electrical PA_SED 8 12.94955 80.22031 conductivity which is the measurement of the water’s ability to conduct the electricity. 3.3.2 Total hardness Table 1: Sampling location details Hardness of water is an aesthetic quality of water 3.2 LOCATION OF SEDIMENTS SAMPLES and is caused by carbonates, bicarbonates, sulphates and chlorides of calcium and The samples were collected during the month of magnesium.

Nearly 8 samples were collected at the 4758 International Journal of Pure and Applied Mathematics Special Issue The maximum permissible limit of total hardness Capacity of water to resist the pH that would for drinking purpose is 300 mg/L. Hardness make the water more acidic. more than 300 mg/L may cause heart and kidney problems. The total hardness in surface water 3.3.6 Phosphorous samples collected from the study area ranged Phosphorus occurs in usual water and in waste from 100-850 mg/L. In the present study the waters almost exclusively as phosphate.
