Quality Assessment of Groundwater in Rampachodavaram Division of East Godavari District, Andhra Pradesh

摘要

Quality of ground water resources in the Rampachodavaram division of East Godavari district in Andhra Pradesh assesed for its suitability for irrigation. For this, one hundred and two (102) ground water samples were collected from study area in pre and post-monsoon seasons of 2017-2018). The ground water samples were analyzed for pH, EC, cations and anions viz., Ca~(2+), Mg~(2+), Na~+, K~+, HCO_3~- CO_3~(2-), Cl~- and SO_4~(2-), SAR and RSC were also calculated. Eighty six per cent (86%) ground watersamples were neutral (pH 6.5-7.S) in reaction in both pre and post- monsoon seasons while EC values of majority of water samples were under C_3 class (EC 0.75-2.25 dS m~(-1) in both pre and post-monsoon seasons. The SAR and RSC values of majority samples were under S_1 (0-10) and A, (< 1.25 me L~(-1)) classes in pre and post-monsoon seasons, respectively.
