“…Omonona et al [25] also reported similar findings in their study. Furthermore, Salmonella / Shigella (enteric pathogens) and Staphylococcus aureus, seen as important indicators of the health of aquatic ecosystems [29] were not observed in the water samples. The total coliform count (TCC) was observed to be higher than the WHO permissible limit for drinking water.…”

Water is very crucial for the survival and maintenance of most living organisms. The quality of water available for plant, animal or human use cannot therefore be compromised. This study therefore examined the physicochemical and microbiological characteristics of water samples in Okomu National Park, Edo State, Nigeria. Water samples were collected from four waterholes (three rivers and one stream) for two seasons (dry and wet) using grab sampling technique. These water samples were analysed for physicochemical [temperature, pH, total dissolved solid, electrical conductivity, total suspended solids, dissolved oxygen (DO), nitrate, chloride, phosphate, sulphate, biological oxygen demand (BOD) and chemical oxygen demand (COD)] and microbiological (total coliform and fungal counts) analyses using standard methods. Data collected were subjected to descriptive statistics and T-test at α 0.05 and compared with WHO permissible limits. The result showed that the mean COD (both seasons) and BOD (dry season) were above the comparable WHO permissible limit while there was no significant difference in the values of all the physicochemical parameters across the seasons of sampling. Salmonella / Shigella and Staphylococcus aureus were observed to be absent while the total coliform and fungi counts were AJEE, 12(1): 7-17, 2020; Article no.AJEE.52880 8 observed to be higher than the WHO permissible limit for drinking water. The detection of Escherichia coli in the water samples (except Arakhuan stream) is an indication of faecal contamination either of animal or human origin. There was significant difference in total heterotrophic bacteria (t=-4.936) and total coliform counts (t=-2.417) in the waters sampled. Constant monitoring of the waterholes and intensified sensitization of the surrounding communities on ecosystem conservation is needed to protect the park's ecosystems. Original Research Article

“…This can be due to the low hospital dynamics; the hospitals are located in small urban agglomerations and rarely are functioning at their maximum capacity. The high pH levels registered or it inhibits the growth of the aquatic macrophytes by impairing iron and phosphorus uptake, and it reduces the fish production (Kumar et al, 2010). Such high pH levels can also damage the waste water collection and treatment facilities (reducing germicidal potential of chloride) and prevent the biological treatment processes (Kumar et al, 2010;WHO, 1996).…”

Hospitals produce large quantities of waste water that may contain various potentially hazardous materials. Moreover, these effluents usually do not undergo any specific treatment before being discharged into the urban sewage networks. As a consequence, a proper management of the hospitals effluents is vital. In the present study, the quality of the effluents, generated by 11 important hospitals from Cluj County was investigated. The analyzed parameters were: pH, chemical and biochemical oxygen demand, total suspended solids, residual free chlorine, and detergents. For all the effluents, the biochemical oxygen demand and the detergents content were within the permissible limits for waste water discharged in the urban sewerage system, while the other parameters exceeded the permissible limits.

The present study was carried out in Kadapa to assess the extent of chemical contaminants by the industries. Effluent samples were collected from selected industries and the physical -chemical parameters were analyzed and compared with ISI standards. Results showed the pH value ranged from 2.1 -12.5. The effluent samples collected showed extremely high Total Dissolved Solid (TDS) for many industries. Sodium was found to be higher than permissible limits. COD is within the recommended limits. These effluents are normally discharged into the surrounding water bodies. So there is urgent need to develop technology to reduce the pollution and make the area safe.
