The effect of corrosion on physiocochemical and microbiological profile of surface water quality from River Udonwankwo, in Ikot Osurua was carried out using standard chemical and microbiological techniques. The results revealed the physiocochemical parameters of control and tested water to include pH, turbidity, Salinity for both samples, Acidity, electrical conductivity, TDS, DO, TSS, total hardness, calcium hardness, magnesium hardness, total alkalinity, chloride, nitrate, nitrite, iron, aluminium, selenium, copper, zinc, barium, fluoride, Sulphate and Phosphate (12.4 and 14.6 mg/l) respectively. Sample A recorded mean bacterial count (1.74 ± 0.04 x 105CFU/g), sample B (2.46 ± 0.04 x 105CFU/g), total coliform count for sample A MPN (82/ml) and sample B MPN (135/ml). Total fungal count for samples A recorded mean count (3.6 ± 0.07 x 104CFU/g) and sample B (1.2 ± 0.06 x 104CFU/g) respectively.

4.2 DISCUSSION OF RESULTS
The effect of corrosion on physiocochemical and microbiological profile of surface water quality revealed that there were significant effects of the physical, chemical and microbiological parameters analyzed. This was justified based on the concentrations (standard) permissible values in the Nigeria Standard for Drinking Water Quality (NSDWQ) and World Health Organization (WHO) standard. Table 4.1 showed the physicochemical properties of surface water samples from River Udonwankwo, in Ikot Osurua, Ikot Ekpene, Akwa Ibom State. All the tested physiochemical parameter of this study was justified according to Nigerian Standard for Drinking Water Quality (NSDWQ). The appearance of the control water was clear while fairly clear and was unaccepted, pH of both water samples were acceptable and its could be observed that increase in pH values leads to increase in alkalinity and decrease in alkalinity leads to increase in corrosion and is in line with work of (Roberge, 2012).
Water quality is considered as the amount of total dissolved solids (minerals) and other impurity presence in 100ml of water sample. These substances (solids) may include pH values, electrical conductivity, salts of chlorides and sulphates, alkalinity, temperature and dissolved oxygen (DO). These presences of these mineral impurities in water could be due to corrosion in water as a results of material used in storage of transporting of water from one point to another point. The above mentioned parameters have a direct effect on the quality of any given water as they affect the concentration these mineral in water when measured in milligram per litre (mg/l.) of the water sample (Popova et al., 2003).
Summary of Chapters
Introduction: This chapter highlights the critical problem of corrosion in water distribution systems and the subsequent health risks posed by contaminated surface water sources in Nigeria.
Materials and Methods: This section details the systematic collection of water samples using a composite method, followed by rigorous chemical and microbiological laboratory analyses to determine quality parameters.
Results and Discussion: This chapter presents comprehensive data on the physicochemical and microbial profiles of the water samples, evaluating them against established regulatory standards to demonstrate the deleterious effects of corrosion.
Conclusion: The study concludes that corrosion significantly degrades water quality, causing an increase in hazardous mineral content while simultaneously altering the microbial load.
Recommendations: This section proposes practical engineering and management solutions, such as the use of corrosion-resistant materials, protective coatings, and improved treatment processes.
