The Kolo Creek is an inland water body in the Niger Delta receiving organic and chemical wastes arising from anthropogenic activities within the catchment area. This study was therefore carried out to investigate the spatial variabilities of heavy metals in surface and sediment and their geochemical factors that influence their presence along the Kolo Creek in 2018 using Geo-accumulation index and pollution load index to extrapolate the level of heavy metal contraction in the two medium. Sediment and Water samples were collected for five (5) months and assessed from eight sampling points (A-h) for seven (7) heavy metals such as  Copper (Cu), Lead (Pb), Iron(Fe), Camium (Cd), Manganese (Mn), Nickel (Ni) and Mercury (Hg). All the heavy metals had geo-accumulation indices below zero which indicates no pollution except Fe which had geo-accumulation index in the range 3.327 in surface water and 7.751 in sediment, furthermore, the pollution load index revealed a toxicity of 0.664 times in surface water as against 1.501 times in sediment exceeding the background concentration in the Kolo Creek. Hence, poor ecological ethics and culture should be discouraged to keep the Kolo Creek water under check for safe domestic water use.

The Kolo Creek is one of the inland water bodies in the Niger Delta receiving organic and chemical wastes 
arising from anthropogenic activities within the catchment area. This study was therefore carried out to investigate the 
impact of human activities on the quality of surface water along the Kolo Creek between 2016-2017 using Water Quality 
Index for missing parameters method in bide of finding a descriptive definition to the water quality status of the Kolo 
Creek. Water samples were collected for ten (10) months each during the dry and wet seasons and assessed from six 
sampling points (A-F) for seven (7) physico-chemical parameters and total coliform counts. All data were analyzed using 
Water Quality Index. The water status from the Kolo Creek is scientifically ranked as medium (Class III), relatively 
moderate, but not good for consumption without further purification. Hence, poor ecological ethics and culture should be 
discouraged to keep the Kolo Creek water under check for safe domestic water use.
