“…On the contrary, works have displayed that heat ailment are small usual in places of massive liquid than in the places of soft liquid [15] this is not detrimental to health. The temperature mean value is 26.37 ± 0.35, a value quite acceptable when compared to WHO [18]. Stipulated standard of 25 o C -28 o C. It can be stated that temperature wise, the surface streams in Camp2 are considered not fit for human consumption since the temperature falls within the range of temperature required for biochemical reactions in the body of a living organisms.…”

Heavy metals and other municipal waste in addition to anthropogenic activities have been observed in surface streams. Since humans consume water every day, it became imperative to evaluate the physicochemical parameters of water and heavy metals concentration in surface streams towards documenting the water quality and streams at Camp2 village, Akamkpa Local Government Area, Cross River State. Methodology: Sample collection bottles were used as specie materials which are really cleaned with substance, cleaned with liquid accompanied by real liquid previous placing in 5%HNO3 for over 24hours. Liquid species were gathered from the surface water bodies by simply scooping. Using plastic bowels into 5litre acid washed polypropylene containers. Samples were collected in two study site, the samples were analyzed for various heavy metals and physicochemical parameters i.e. pH, D.O, Temp, Electrical Conductivity, Total dissolved oxygen, Turbidity, and Total hardness by using standard methods and procedures while heavy metals such Ni, Cd, pb, Hg, As, were also analyzed using Atomic Absorption Spectrophotometer (AAS). Results: The physicochemical parameters and heavy metals shows that all the parameters analyzed fell below WHO (2010) Standards for drinking water except for temperature and total hardness which are significantly(P<0.05) within WHO Standards (2010). Also, the results of the heavy metals concentration were above permissibility limits. Hence, these values were above WHO standard (0.1mg/l) and FAO/WHO standards of (0.2mg/kg) while others were within joint FAO/WHO standard limit. Conclusion: Contamination of surface streams in the community has threating both humans’ health and animals including water quality. Therefore, the introduction of physical and chemical heavy metal remediation is required to protect our surface streams within the Environment.

“…In Nigeria, arsenic has been detected in drinking water sources (both surface water and groundwater) above acceptable levels of 0.01mg/l in the Northern region with a concentration of 0.02 to 0.80mg/l [2]. Such Northern regions with high arsenic contamination include Biu Volcanic North-Eastern Province of Nigeria [16], Kano [17], Zaria and environs [18], Kaduna [3,4], Borno [19], and Sokoto [20] and also, it has been detected in high concentration in some places in south western Nigeria, such places include Osun and Ogun States [21][22][23]. Although, arsenic contamination is not too severe in the south-south region of Nigeria, however some levels have been detected in some areas and it's below the permissible limit of 0.01mg/l [2] for drinking water.…”

Arsenic has a detrimental effect on both the environment and humans. In many parts of the world, arsenic has been detected in drinking water sources above acceptable levels. Considering the fact that millions of people are at high risk of arsenic poisoning via water intake, arsenic remediation from drinking water has become a global issue of serious concern. Chemical coagulants are already being used for treatment but their enormous cost, human and environmental issues associated with their use have led to searching for alternatives like natural coagulants (plant-based). In this study, laboratory scale studies using jar test experiments were performed on synthetic arsenite contaminated groundwater to analyse the efficiency of Arachis hypogaea (groundnut seed) on the treatment of arsenic contaminated water. Experiments were carried out using synthetic arsenite contaminated borehole water with pH kept constant at 7.30. Results indicated that groundnut seed extract was able to significantly reduced arsenite in water either as primary coagulant or as coagulant aid (using alum as primary coagulant). As primary coagulant, above 90% arsenite reduction was achieved and as a coagulant aid about 99.97% arsenite reduction was achieved. The pH of the treated water was within neutral (basic) due to the buffering capacity of the seed extract. Therefore, results from this study revealed that groundnut seed has potential for use as primary coagulant or as coagulant aid (with alum as primary coagulant) for the treatment of arsenic contaminated groundwater.

This study determined the physicochemical parameters, microbial properties and heavy metal speciation of groundwater in major towns of Ife North Local Government, Area of Osun State, Nigeria, with a view to evaluating the safety of groundwater. Water samples were collected during the dry season (December, 2015 to February, 2016) and wet season (May to July, 2016). A total of 72 samples were collected for the 6 months. Physicochemical parameters were determined in situ while total coliform count was done by membrane filtration techniques. The sequential extraction procedure was used to fractionate the metals (As, Pb, Cd, Cr, Cu, Mn, Ni and Zn) in the water samples. The concentrations of the metals were quantitatively determined using Atomic Absorption Spectrophotometer (AAS, PG 990 Series). The results of the physicochemical parameters of water showed that the pH (6.22-9.93), electrical conductivity (126.02-606.65 µs cm −1), total dissolved solids (78.37-705.31 mg L −1), oxidation reduction potential (303.44-330.17 mV) and temperature (25.83-28.93 °C) were within the limit stipulated for drinking and domestic water. The bacterial flora identified includes Escherichia coli, Yersinra spp, Entrerbacter spp, Citrobacter spp, Seirantia spp, Klebsella spp and Rhebrella spp. The metal speciation revealed free metal ions had the highest concentration with the order free metal ions > suspended particles > bound to organic substances. The study concluded that the groundwaters of the studied area were polluted with microorganisms and the investigated heavy metal, require treatment and monitoring to safeguard human health.
