No full textEvaluation of Bacteriological Quality of Surface, Well, Borehole and River Water in Khana Local Government Area of Rivers State, Niger Delta
No full textIn most rural cŽmmƵnŝƟĞƐ͕ water is consumed without ƚĞƐƟnŐ its potability and the major sources of water apart from rainfall are surface and river water; in some cases, borehole water. Water samples from surface, river, well and borehole water in ĚŝīĞrĞnƚ CŽmmƵnŝƟĞƐ in Khana Local government area was randomly collected and bacteriological analysis was carried out on them. The results showed that the least microbial load was from that of borehole water which had an average microbial load of 1.78 × 103 while river water had the highest microbial load with a mean count of 5.48 × 104 . Surface water, however, had the highest total coliform (42.6/100 mL) and faecal coliform count (14.8/100 mL) while borehole water had the least total coliform (4.6/100 mL) and faecal coliform (0) count. /ƐŽůĂƟŽn and ŝĚĞnƟĮcĂƟŽn of the isolates showed that Bacillus spp was the most isolated with an occurrence of 7 (23.3%). Other organisms isolated included Staphylococcus aureus, Shigella spp, Salmonella spp, Enterobacter spp, Streptococcus spp, Proteus spp and Escherichia coli. Most of these organisms are gram nĞŐĂƟvĞ microorganisms and are usually associated with ŐĂƐƚrŽŝnƚĞƐƟnĂů illness. Proper treatment and surveillance of these water sources should therefore be carried out regularly to prevent public health issues that could be implicated from such unwholesome ƉrĂcƟcĞ of drinking non-potable wate

No full textThe upsurge of abattoir operations as a result of the rise in demand for meat protein has led to a corresponding increase in waste generation. These wastes are often channelled into nearby streams with little or no treatment which exposes aquatic organisms to the resultant consequences of this waste deposition. This study was thus aimed at determining the physicochemical quality of some abattoir samples in Port Harcourt city. Soil, faecal matter, wastewater, waste blood and service water samples from the Iwofe, Rumuodomaya and Trans-Amadi abattoirs were collected within a period of one year and the pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD5), sulphate, chloride, temperature, nitrate, ammonia and heavy metals quantities including chromium, lead, zinc, cobalt, copper and cadmium were determined using standard techniques. The study recorded high BOD5 and COD values from the blood, faecal matter, soil and wastewater samples while service water samples had values within the Nigerian Standard for Drinking Water Quality limits. Seasonal variations in the physicochemical parameters of the samples collected both in the wet and dry seasons were observed. The pH values ranged from 6.2-8.5, BOD5 of blood, faecal matter soil and wastewater ranged from 2124-4349 mg/l while the COD ranged from 2715-8820 mg/l. In Rumuodomaya, the BOD5 and COD ranged from 2276-2727 mg/l and 2583-3245 mg/l respectively while samples from Trans-Amadi abattoir had values for BOD5 and COD ranging from 2253-4330 mg/l and 2931-4597 mg/l, respectively. Nitrate, chromium, cadmium, zinc, cobalt, lead and copper contents in the different locations varied statistically at α-0.05 while no significant difference was observed for pH, ammonia, temperature, COD, BOD5, sulphate and chloride contents at α=0.05. The BOD5 and COD of waste blood, wastewater, soil and faecal matter recorded values that were above permissible limits for service water and therefore raises concern for the aquatic life being threatened by these effluents as the amount of dissolved oxygen available for them will be reduced as a pollution of the immediate environment, if these generated wastes are not treated before disposal.
