“…The temperature of the environmental waters and wastewaters used in this study were within the optimum temperature range for the survival of most mesophiles but the temperature recorded for borehole water is higher than the permissible standard of 25 o C (14). Generally, the temperature range of the waters recorded in this study is higher than previous studies where temperature ranges within 25±2˚C were reported (17,18,19). The variation in the temperatures may be due to seasonal and geographical influence on the samples collected.…”

“…The pH values of the water and wastewater samples varied from slightly acidic to slightly alkaline (5.0-9.7) which are however slightly higher than the recommended range for wastewaters (6.5-9.0) and surface/ground waters (6.0-8.0). The acidic pH and high turbidity observed in the domestic wastewater could be influenced by the nature of the organic and inorganic contents such as sewage, detergents and toxic elements (19). Fish wastes and fish feeds contain carbonate salts that can make water more basic, hence the fairly higher alkalinity observed in fishery wastewater compared to the environmental waters.…”

Background: Coliform bacteria are majorly introduced into water bodies (river and wastewater) as a result of faecal pollution, agricultural runoffs and several anthropogenic activities. Despite the effectiveness of water treatment methods, pathogens still persist in water; hence the relevance of assessing the ability of these pathogens to survive the lethal actions of physical stresses and the possible impact on antibiotic susceptibility pattern of the organisms. Methodology: The survivability of Escherichia coli strains (NCM3722, FAP1 and ST2747), Enterobacter cloacae GGT036 and Shigella sonnei 53G was assessed in environmental and waste waters for 21 days. The effect of three treatment regimens (UV radiation, solar radiation and boiling) on the survival of the coliforms was evaluated. Also, the antibiogram of the isolates post-UV exposure was assayed. Results: Although there was significant reduction (≥ 3-log) in the population of the bacteria overtime, all the coliforms survived in the waters for 21 days. The effect of UV radiation was significant on all organisms (> 3 log reductions). Solar radiation for 60 minutes had significantly lesser effect than boiling for 15 minutes. Surviving cells of all isolates demonstrated multiple drug-resistance post exposure to UV radiation. Conclusion: This study revealed the ability of coliforms to persist in waters after treatment and proves that UV radiation may not be effective in attenuation of antibiotic resistance.

“…However, for the high electrical conductivity recorded in the groundwater bodies, there are several factors which need to be taken into considerations such as the land uses and geology around the monitoring wells. Electrical conductivity was high during dry season in a majority of the monitoring wells, similar to Awoyemi et al (2014) in Lagos State, Nigeria. However, this finding contradicted the results of Reddy et al (2011) where the increasing electrical conductivity was proportionate to the increasing water table whereas this study revealed that the electrical conductivity was high in low water table during the dry season.…”

This paper emphasized the hydro geochemistry of groundwater in Banting, Kuala Langat, Selangor and the hydrogeological properties which contribute to the potential degrading of the quality of the groundwater. The groundwater characteristics in Banting, Kuala Langat, Selangor are influenced by aquifer types and the geomorphology of the area. Groundwater samples were collected at thirteen monitoring wells from February 2017 to January 2018. The thirteen selected monitoring wells for this study is scattered in agricultural areas. The investigation of groundwater measured the physical parameters which are total dissolved solid, electrical conductivity, salinity and chemical oxygen demands. Major ions such as chloride, calcium, magnesium, potassium, sodium bicarbonate and strontium were also calculated. Iron, manganese and zinc which are heavy metal elements together with phosphate, nitrate and sulfate were considered as inorganic parameters in this analysis. The groundwater samples have influences from the seawater intrusions as significantly high major ions concentration were detected. Non-point pollution from the agricultural practices does not deteriorate the groundwater quality even though the monitoring wells are located in agricultural areas. Groundwater sources in the current study are suitable for domestic use and agricultural irrigation.

“…That is, dissolved oxygen increases with increase in water quality and vice-versa. Bulley and Husdon [18] reported that most systems that are designed for the aerobic treatment of municipal waste recommend the dissolved oxygen concentration be maintained in the range of 0.5 -2 mg L -1 this was supported by Awoyemi et al [19]that reported a DO of 0.6 mg L -1 of a domestic wastewater. The level of DO in wastewater depicts the degree of contamination of the wastewater by organic matter.…”

The environment is a treasure that needs to be protected from point and diffuse sources of pollution. Most wastewater treatment plants cannot attain 100% efficiencies and this call for tertiary treatment process before discharging final treated wastewater into the environment. The study focused on harnessing the locally available materials, sand and granulated Palm Kernel Shell (gPKS) as filters for treatment of wastewater from constructed wetland using intermittent filtration system in the laboratory. The filter depth and hydraulic loading rate was 650 mm and 0.135 L min -1 , respectively. Applied wastewater was effluent from the Constructed Wetland (CW) of wastewater treatment plant University of Lagos. The filtration system was dosed intermittently 6 hourly for 12 weeks. Experimental results showed that pH of the effluent from gPKS filter medium was slightly reduced to the influent due to acidic nature of the gPKS while effluent from sand filter slightly increased. The five day biochemical oxygen demand (BOD5) removal efficiency for the gPKS and sand filters were 59.2 and 69.08% respectively, while the corresponding average Dissolve Oxygen (DO) were 2.9 ± 0.6 mg L -1 and 3.4 ± 0.345. The percentage removal of E. coli in sand and gPKS filters are 69.34% and 87.49% respectively.
