opened in 1998 and still in operation till date. The leachate emanated from
decomposed solid wastes have adverse effects on nearby groundwater sources.
The aim of this study was to assess the groundwater quality using an indexing
approach from existing hand-dug wells bordering this active landfill site and
assess its suitability for drinking and domestic purposes during dry and wet
season. Ten water samples from different locations within the landfill were
identified for groundwater sampling. The samples were collected in March and
August, 2013 and analyzed for different physico-chemical parameters. The analyzed
physicochemical parameters such as pH, TDS, TH, HCO3¯, CO3¯,
Cl¯, NO3¯, SO42¯, Na+,
K+, Ca2+ and Mg2+ fall within the standard
limits of WHO and NSDWQ. The values of GWQI of water samples during dry and
wet seasons were found in the range of 16.8-38.4 and 11.4-48.9, respectively.
About 50% of sampling waters belong to Excellent
water status and 50% under Good
class during dry season. During wet season, 70% of sampling points come under
Excellent water status
while 30% belongs to Good
water status. The GWQI value of each well for both seasons revealed their fitness
for drinking and human consumption purposes. Pearsons
correlation coefficients among selected water quality parameters show very strong
association between EC and TDS in both seasons.]]>Armah, F.A., I. Luginaah and B. Ason,201211115Gupta, P. and S. Roy,201221930Mishra, P.C. and R.K. Patel,20015293298Ramakrishnaiah, C.R., C.
