Abstract
ABSTRACT
Study on arsenic pollution was conducted in Onitsha town in Anambra State,
Nigeria to examine the pollution status of surface and subsurface water.
Arsenic concentration in surface water within Onitsha metropolis ranged from
0.2001 mg/L (River Niger upstream) to 1.5883 mg/L (River Niger central
drainage surface), while concentration in boreholes lies within the range of
0.0000 mg/L (22.2% of boreholes) and 1.2507 mg/L (creek road), respectively.
Arsenic concentration in sampled water from river sources is above the WHO
standard (0.01 mg/ L) while 87.8% of Arsenic concentration in boreholes
adjacent and closest to these rivers and creek is also above the world Health
Organization standard (WHO, 2011) of mg/L. it is discovered that pollution of
surface water is greater than that of the groundwater sources. Major sources
