This report gives the correlation and microbial analyses of groundwater, in a rural community, in the South-South of Nigeria for wet and dry season monitoring. Sampling of borehole (BH) and hand-dug well (HDW) water samples was done for eight (8) consecutive months, beginning from May 01 2016 to January 31, 2017; to cover for wet and dry seasons. In line with standard methods of APHA (2012), over thirty (30) water quality properties were measured and correlated. Results of the correlation

The correlation analysis also showed that while Cland SO4 2did not exhibit strong preferential affinity for any of the cations, NO3was perfectly correlated with Mg (-0.91) and Cd (0.98), and very strongly with Ca (-0.85) and Ba (0.84). The microbial analysis result revealed that BHs were cleaner sources of potable water in the community, compared with hand-dug wells.
