Time series inorganic groundwater data for the Oju/Obi area of Eastern Nigeria from 1997 and 1998. Rainfall chloride time series data from selected rain gauges from 1997. Clay mineralogy data from selected boreholes in Oju and Obi.
Oju/Obi is a remote part of Eastern Nigeria. There are severe water shortages during the 4-5 month dry season. The hydrogeology of the area is complex, and groundwater is difficult to find. In an attempt to understand and quantify the available groundwater resources within the area, DFID commissioned BGS from 1997 – 2000 to carry out a hydrogeological review of the area and devise appropriate and effective methods for siting wells and boreholes assessing groundwater resources and how best these resources could be developed. The field study involved the collection of time series data including groundwater chemistry and rainfall Cl along with mineralogical information. These results are being used by WaterAid, Local and regional Government to help local communities develop sustainable water supplies.

Data Quality
Samples were collected from selected groundwater sources and rain gauges for a hydrogeological review of the area. Mineralogical samples were taken from the first 10 m of selected boreholes. X-Ray diffraction was used to determine clay mineralogy. A subset of samples were analysed for whole rock particle size analysis.
