ARSENIC POLLUTION OF THE SUBSURFACE WATER
ABSTRACT This work investigates the extent of Arsenic pollution of borehole waters in Onitsha and environs. Fifteen samples of drinking water sourced from boreholes were randomly collected and analyzed using Atomic Absorption Spectrometry (AAS) and the technique employed is wet oxidation method. The results of Arsenic concentration obtained from the boreholes ranged from 0.00 mg/L (53.33% of boreholes) to 1.099mg/L (46.67% of boreholes). Seven out of the fifteen samples were ...
