Abstract
This studv evaluated contamination of groundwater with toxic metals in and around Oke diya dumpstle and Limestone
quarry in. Sagamu Southwestern Nigeria. The pH values for rhe Gruu;1dwater 11·ere acrdic based on pH with a range of 3 3 to 6. 6 and a slight increase of the values along the groundwater ;7ow direction which is geaerally towards th ecastem pnu of -·
the study area. Values of Total Dissolved Solids and Electrical Conductivrry were b~ Me en 57 to I 538mgll and 88 to
2366us/cm respectively which classify the water in the stud)· aren as}i-esh 10 slightly sali~:e. Hi'lher values were observed 111

plasma optical emission spectrometry (fCP-OES) analytical method at Act/nbs in Canad::J. Water samples around Wll PCO
