The research was carried out to evaluate major source influencing chemical quality of groundwater within suburban area of Abakaliki. A total of twenty one (21) groundwater samples were collected and analyzed. Parameter analyzed were; EC, pH, TDS, Cl¯, Na+, Mg2+, NO3¯, SO42¯, Ca2+, HCO3¯, K+, CO32¯ these parameter were analyzed using American Public Health Association standard method. Gibbs, Mg2+/Ca2+, End-member, Diamond field of Piper and Parson plots were used to indentify major source influencing groundwater chemistry within the study. Finding, from Gibbs plot and Mg2+/Ca2+ against Mg2+/Na+ revealed that rock dominance is the major process that control groundwater chemistry, while End-member plot showed that silicate and carbonate weathering are the two weathering process that influence groundwater chemistry within the study area. Diamond field of Piper by Lawrence and Bal-Subramanian modified, revealed that groundwater falls within High Ca + Mg & SO4 + Cl. Parson plot revealed that 65 % of groundwater falls within Ca – Mg – Cl water type, while 35 % falls within Ca – Mg – SO4. Relationship between TDS vs TH plots showed that groundwater samples fall within soft – fresh water category. The results of the geochemical survey reveal major ionic components trend in other of Mg>Ca>Na>HCO3>SO4>Cl, result reveal that there is no particular trend of ions movement in groundwater.
