The Secondary data were collected from the CGWB office Chennai, tharamani during pre-and postmonsoon periods of 2010. The groundwater quality assessment has been carried out by evaluating the physicochemical Parameters such as pH, EC, TDS, HCO3-, Cl-, SO4, Ca2+, and Mg2+ for both the seasons. Based on these parameters, groundwater as been assessed in favour of its suitability for drinking and irrigation purpose. Dominant cations for Pre and Post the seasons are in the order of Na+ > Mg2+ > Ca2+ >K, and Mg2+Na+ >Ca2+>K while the dominant anions both post monsoon and pre monsoon have the trends of HCO3 ->Cl- >CO3>Fl-, respectively. Analytical results observed from various indices reveal that the groundwater quality is good in some places recently polluted by the waste materials. The observed chemical variations in pre-monsoon and postmonsoon seasons may be the effect to rock-water interactions, ion-exchange reactions, and runoff of fertilizers from the surrounding agricultural lands.","PeriodicalId":437898,"journal":{"name":"The Asian Review of Civil Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116084511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dumping of MSW in uncontrolled landfills can cause major impact on human health and surrounding environment. Leachate is the main culprit, causing pollution of surface water bodies and ground water. Ground water once contaminated, is very difficult task to improve. The aim of research study is to determine the leachate characteristics of Alevoor landfill near Udupi, India. The pH of samples was 8.21 and 7.77 respectively. This paper also presents the leachate contamination potential of Alevoor landfill using Rand Corporation Delphi Technique. The leachate pollution index (LPI) represents the level of contamination potential of given landfill. LPI is a single number express the overall leachate contamination potential of landfill based on several leachate pollution parameters at a given time. The LPI is also used to compare the contamination potential of different leachate sampling stations of Alevoor landfill. The LPI values of the Alevoor landfill is significantly high and proper treatment is required before the discharge of the leachate.","PeriodicalId":437898,"journal":{"name":"The Asian Review of Civil Engineering","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127079656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It lies between 10 ° 13’ N and 11 ° 23’ N latitudes and 76 ° 39’ E and 77 ° 30’ E longitudes with a total geographical area of about 7469 km2.Water is the basic element of social and economic infrastructure and is essential for a healthy society and sustainable development .Coimbatore is one of the major developing citiesin India .Ground water is being the favourite alternative to water provided through taps,is facing threats due to anthropogenic activities in India, which has led to deterioration of ground water quality. In addition to the source contamination,urbanization and improper disposal of solid wastes lead to contamination of groundwater and surface water resources in this region. Municipal and industrial wastes of the city are presently disposed at four distinct open tanks namely Narasampathy, Krishnampathy, Selvampathyand Kumaraswamy/(muthannankulam) tanks. The leaches of these wastes directly contaminate the groundwater and surface water resources leading unsuitability of water for drinking at many places. Hence, a detailed study has been carried out using Geographical Information System (GIS) to understand the spatial variation of surface water and groundwater quality. About sixteen groundwater samples and sixteen surface water samples are to be collected during monsoon and post monsoon periods of the year – 2014& 2015 from the study region, and the samples have to be analyzed for various physical and chemical parameters such as pH, Electrical Conductivity, Total Dissolved Solids, Alkalinity,Hardness, Na+, K+, Ca2+, Mg2+, Cl•, HCO3•, CO32•, SO4, NO3 and F. The concentrations of physical and chemical constituents inthe water samples are going to compared with the Bureau of Indian Standard (BIS) and World Health Organization (WHO) standard to know the suitability of water for drinking.The study indicates that the water quality parameters exceed the permissible limits fordrinking at many locations leading the water unsuitable for drinking. The spatial variation of groundwater quality parameters is also yet to be plotted using GIS.","PeriodicalId":437898,"journal":{"name":"The Asian Review of Civil Engineering","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116942636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
