المستخلص: Produced water is considered one of the common environmental problems at present. This water is trapped in underground formations which come to the surface during oil and gas production. The produced water's effect lies in its disposal process, into pits that cause pollution to the surrounding environment .At time, the pits take up a large area, vertically and horizontally, where some pollutants may reach the groundwater in several ways. The purposes of this study are to describe the areal distribution of the dominant water quality constituents, to identify the major hydro-geochemical processes that affect the water quality and to evaluate if any relations of produced water, groundwater quality and geochemistry of water in aquifer in the surrounding areas of Nafoora oil field in NE Sirt Basin, Libya. This was done by taking samples from both and analyzing them through field and laboratory analyses. Ten samples of groundwater wells used for domestic and injection while, Twenty-six samples from produced water pit from the selected area were analyses for major physical, chemical properties and trace element. For interpretation, these results were used for conventional classification techniques: (Piper and Stiff) diagrams from Rock Works 17 software, GIS software, and Surfer 10 software. The results revealed no relationship or influence of produced water to the groundwater quality, whether in terms of salinity or hydrocarbon pollution.
