The aims of current study is to measure quality of groundwater in the vicinity of the JNPC industrial area in Parawada, Visakhapatnam, Andhra Pradesh, India, from 2019 to 2020 using the water quality index (WQI). A simple random sampling technique was used to obtain 198 groundwater samples for this investigation from 32 bore wells and 1 open well in the studying zone to check the ground waterportability. The sulphates (SO4-2), total dissolved solids (TDS),total alkalinity (TA),pH,turbidity, magnesium (Mg2+), dissolved oxygen (DO),chlorides (Cl-),phosphates (PO4-2),nitrate (NO3-), residual free chlorine , Bio-chemical oxygen demand,fluorides (F-),total hardness (TH), calcium (Ca2+), and heavy metals such as iron (Fe+3) and zinc (Zn+2) were used as parameters in this study. Following that, the findings are compared to BIS (IS 10500:2012) and WHO drinking water standards.As a result, the WQI ranges from 14.18 to 390.6 for 33 stations. The average concentration level of anions is as follows: Cl-> SO4-2> NO3-> F-> PO4-2, where the order of the sodium, calcium, potassium, and magnesium ions in the average concentration level is: Na+ > Ca+2 > Mg+2 > K+.During the study period, hydrochemicalfacies such as mixed Ca+2-Mg+2-Cl and mixed CaNaHCO3 were observed in the groundwater of the research region. Furthermore, 21 samples are classified as having excellent water quality, 5 as having good water quality, 17 as having moderate water quality, 3 as having poor water quality, 15 as having very poor water quality, and the remaining 137 as being not suitable for drinking water quality. However, Area 2 sampling stations BS8, BS9, and BS13 have excellent water quality, whereas Area 3 and 4 sampling stations were mostly affected. As a result, the analysis shows that some conventional treatment is necessary before using the groundwater in the studied area.
