Wastewater and sediment samples from selected locations of the Ntanwogba creek in the metropolitan city of Port Harcourt were collected. Physicochemical parameters were determined using standard analytical procedures. The results of the physicochemical analysis of the wastewater at different locations in this study was reported to have fell short of the recommended limits in terms of the turbidity, BOD5, nitrate, pH, TDS, temperature, DO, COD and chloride concentrations. The pH of the wastewater effluent samples ranged from 6.4–7.4, while sediments ranged from 5.3–5.7, the temperature regime for the samples at all study sites ranged 26.6-29.50C. Similarly, TDS and EC levels from wastewater samples ranged from 375–449 mg/l and 501-812.6 µS/cm, respectively.  BOD5 ranges from 33.6 to 201.6 mg/l while chloride concentrations ranged from 34.30-61.06 mg/l. Similar trends were observed for sediments in all stations. The physicochemical characteristics from both sources were statistically significantly different at p < 0.05, and these values were not within the recommended limits for such effluents throughout the sampling period. The conclusion is that wastewater with a high domestic load has the highest negative impact on water quality in a river which suggests that the water resources has lost it potability. This calls for urgent attention for responsible agencies to ensure proper implementation of waste management policies to sanitize our environment. This is because failure to enforce the regulations might pose severe threat to receiving water bodies/resources.

Port Harcourt municipality, southern Nigeria, is faced with environmental problems with slums and informal settlements communities, ranging from use of poor and overstressed facilities and inadequate water and electricity supplies and lack appropriate garbage disposal facilities and good drainage systems resulting in perennial flooding due to blocked drainage systems resulting in a number of diseases, such as malaria, diarrhea, cold and cough. Communities are densely populated, with more than five people living in a room. Therefore this study was carried out to assess the public health status of slums/ informal settlements in Port Harcourt Municipality in Rivers state. The study utilized a mixed-method approach. A cross-sectional survey questionnaire and in-depth interview were used to collect data. A total of 180 Questionnaires were distributed across the  five (5) selected waterfronts communities in the survey and key informants were interviewed to obtain detailed information about the status of the various communities in the Informal settlements studied. The results of the study revealed that the most prevalent illnesses in all Slums/Informal Settlements were malaria, typhoid, dysentery, diarrhea, coughing, worm infestation, and skin infection. The prevalence rate of infectious disease recorded for all slums/Informal settlements show that Malaria had 15-17%; Typhoid fever14-16%, Diarrhea 11-13%, Dysentery 12-14%, Cough 5-10%, Worm infestation 8-11% and Skin infections 2-4%.  However, Malaria remains the foremost killer disease in Nigeria. It accounts for over 25% of under 5 mortality, 30% childhood mortality and 11% maternal mortality. These results suggest that people living in slums are predisposed to severe outbreak of epidemics, therefore requires an urgent attention for comprehensive interventions from the government and other organizations to strengthen existing programs to improve the public health and quality of life of this vulnerable population.
