Spatial Distribution of Iron (Fe2+) and Hydrogen Sulphide (H2S) in Exploited Groundwater of Obubra, South Eastern Nigeria

Odong PO*, Chukwu GU, Ijeh Boniface I and Umera RB

This study focused on detecting the distribution and presence of Iron and hydrogen sulphide in the exploited groundwater of Obubra to assess its quality for drinking and other domestic purposes. Groundwater samples were collected from fifteen different locations. The samples were analyzed and results show that more than eighty five percent of the exploited groundwater is below NDWQS/WHO standard. The wide distribution of Iron and hydrogen sulphide in the groundwater could be attributed to the subsurface geology. However, results show that groundwater samples of S1 and S9 meet the NDWQS/WHO standard. Coincidentally, S1 and S9 have the highest elevation in the study area. Sample 4 (S4) with concentration of 25.8 mg/l has the highest iron concentration in the area. Though, sample 11 (S11) was collected from an artesian well, it did not meet the required standard for drinking. Most of the groundwater has objectionable taste and odour. In most of the areas, the Iron concentration of groundwater indicates that the water will not be suitable for laundry.
