Assessment of Some Physico-Chemical Characteristics and Heavy Metals in Some Groundwater Samples Along the Budhi Gandak Belt of Muzaffarpur District During Monsoon Season

摘要

This paper presents quality of water samples from bored tube wells at different sites along the Budhi Gandak belt from Akharaghat to Musahari in Muzaffarpur district of Bihar state during monsoon season of 2011. The parameters such as pH, conductivity, TDS, DO, total hardness, alkalinity, sodium, potassium, calcium, magnesium and chloride as well as heavy metals such as Cu, Zn, Fe and As have been studied. TDS of almost all samples exceeded the maximum permissible limit of WHO. Iron was also found much above the maximum permissible limit in nearly all the samples. The water samples along Budhi Gandak belt under study have arsenic contamination in some samples which even much exceeded the maximum permissible limit at certain sites. The arsenic contamination in the groundwater of this area is serious concern for human health.
