Assessment of water quality in Canaanland, Ota, Southwest Nigeria

Abstract

In this study, water points in Canaanland, Ota, and nearby Iju River were analyzed for biological and physicochemical properties including heavy metal content. Water quality parameters examined were pH, alkalinity, salinity, conductivity, turbidity, total hardness, total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), dissolved oxygen (Do), biochemical oxygen demand (BOD), iron (Fe), lead (Pb), zinc (Zn) and chromium (Cr). All the water samples were slightly acidic (5.96 -6.54) except the bottled/ sachet Hebron water and Iju River water. The results were compared against drinking water quality standards laid by World Health Organization (WHO) and Nigerian Standard for Drinking Water (NSDW). The potable water samples were within the standards for consumable water and so are considered safe for human consumption. The surface waters, on the other hand, have high levels of total dissolved solids, conductivity and salinity. The BOD of the effluent water showed that the water was contaminated and the use of the water for domestic purposes by the inhabitants could lead to hazardous side effects.

Assessment of Anthropogenic Activities on Water Quality of Benin River

“…Heavy or trace metals were determined after digestion of the solution of the samples using Pye Unican SP Atomic Absorption Spectrometry. The essence of the digestion before analysis was to reduce organic matter interference and convert metal to a form that can be analyzed by Atomic Absorption Spectrometry (Chinedu, et al, 2011).…”

Assessment of chemical and bacteriological quality of pipe-borne water from various locations in Delta State University, Abraka, Nigeria

“…Florea and Busselberg (2006) and Hung and Hsu (2004) reported that some trace elements are potentially toxic. Zinc and copper are essential elements for the maintenance of the body's metabolic activities but copper contaminated water could pose health hazards such as abdominal pains, nausea, vomiting, diarrhoea, headache and dizziness as reported by Chinwe et al (2010). Copper poisoning principally influences formation of liver cirrhosis known as non-India childhood cirrhosis (WHO, 2003).…”

Assessment of water quality of Obueyinomo River, Ovia North East Local Government Area, Edo State, Southern Nigeria

“…In this study the WQI was considered for human consumption and the maximum permissible WQI for the drinking water was taken as 100 score (Table 1). (Chinedu et al, 2011). The conductivity values obtained in this study were low when compared to the range of 102.90 -513.08 µS/cm obtained by Duru and Nwanekwu (2012) in their study of physicochemical and microbial status of Nworie River, Owerri, Imo State, Nigeria.…”
