Water is the elixir of life which is essential for proper metabolic processes to take place. The quest for cheap and readily available source of potable water has led to the emergence of sachet and bottle water which the sale and consumption continue to grow astronomically and rapidly in most countries of the world. This study was aimed at assessing the microbial and physicochemical water quality of table water sold on School campuses. Standard microbiological procedures were used to isolate and identify various microbial genera associated with the water samples using morphological, microscopic and biochemical characterization method. The bacterial genera identified were Escherichia sp., Streptococcus sp., Micrococcus sp., Vibrio cholera., Staphylococcus sp. and Bacillus sp. with Choba campus having the highest microbial contamination of packaged water. However, the results of the physicochemical properties from this study were all below the WHO recommended limits. The temperature and pH ranged between 26-27°C and 6.98-7.08, respectively. The values of the electrical conductivity ranged from 0.080 to 0.150 µs/cm; turbidity ranged between 0.40-1.40 NTU; chloride ranged between 1.187-2.103 mg/l, nitrate was within the range of 0.01 to 0.14 mg/l; BOD ranged from 0.02-0.04 mg/l, COD was between 0.00-0.08 mg/l and the total soluble solids were between the ranges of 0.04-0.10 mg/l. Therefore, this study suggests the improvement of water-borne disease preventive and control measures, and monitoring of water quality by the regulatory agencies to ensure good manufacturing practices by the water bottling companies which will result in reduction of health hazards associated with water borne diseases.

Plankton Communities

Composition of plankton communities in two ponds at African Regional Agriculture Centre (ARAC) Aluu, Port Harcourt was undertaken between May and June 2004, to assess the composition, relative abundance and distribution of plankton. The diversity of plankton was poor. Twenty-eight taxa representing four (4) families were recorded for phytoplankton while seventeen taxa representing four families were identified for zooplankton. Chlorophyta and Cladocera were the most dominant classes in phytoplankton and zooplankton in terms of abundance, constitute 13.0% and 17.1% respectively. The water quality of the ponds is evident by high temperature (28.80C), depth (57.5cm), transparency (42), dissolved oxygen (4.9mg/l) and low BOD of (1.4mg/l). The lower density of organisms could be partly attributed due to heavy rainfall which destabilize the surface water and substrate. Hence, extensive studies of the ponds where aquatic organisms are kept should be carried out to maintain proper utilization of ponds.KEYWORDS: Plankton, composition, communities richness, abundance.

The University

The University Center of Biological and Agricultural Sciences (CUCBA) of the University of Guadalajara receives approximately 5700 students, and 1500 of the academic, administrative and visiting staff. The CUCBA is research oriented, therefore, large amount of chemical waste and microbial load is generated by health services. There are two sources of water supply that provide quality drinking water to the student population and two water treatment plants that process the wastewater produced. The objective of this study was to evaluate the physical chemical and bacteriological quality of the water from the sources of supply, storage tanks, distribution network and principals points of use as an area of food and drinkers, as well as the wastewater emitted in triplicate. The water quality index was calculated, and regular values of the water quality of the 10 sampled points were found, and it is noted that, the sampling points with the lowest quality index were the water that leaves the plants of Water treatment, therefore, is not being accomplished with proper water purification.

Main Influence

Through the pavement runoff monitoring of USST（the University of Shanghai for Science and Technology） courtyard pavement runoff and JunGong road runoff, the analysis of main influence factors and pollution degree, this article indicate that underling surface, rainfall duration, rainfall intensity and rainfall are important influencing factors of initial runoff water quality. Organic and suspended solid are the main pollutants of urban runoff. COD, SS and turbidity are the main pollution index, and they present exponential change law and finally achieved stability along with the delay of rainfall. The more heavily it rains, the more quickly water quality become stabilization. Stable water quality are influenced by rainfall character and pavement character. The more heavily it rains, the better stable water quality is. The more dust pavement contain, the worse stable water quality is. Stable water quality of courtyard pavement runoff are better than street runoff.

In this study, the sanitary quality of tap water sources within the University of Port Harcourt was investigated in order to determine its suitability for drinking and other domestic applications. Eight composite samples of tap water were collected from Eight different locations within the three campuses of the University of Port Harcourt using 300 ml-capacity sterile containers. These locations included NDDC Hostel, Sports Hostel, Medical Hostel, NUH Hostel, Dan Etete Hostel, Delta A Hostel, Delta B Hostel and Choba Campus. After collection, water samples were taken to the laboratory for enumeration and identification of Total heterotrophic bacteria (THB), Total coliform (TC) and Faecal coliform (FC) using the membrane filtration method. Result showed that the average THB, TC and FC counts recorded in the tap water samples across the eight locations ranged from 12.4 CFU to 36.7 CFU, 4.3 CFU to 10.1 CFU and 2.8 CFU to 5.2 CFU per 100ml respectively. Bacterial isolates were identified as probably belonging to genera such as Bacillus spp., Klebsiella spp., Enterobacter spp., Staphylococcus spp., Proteus spp., Citrobacter spp., Serratia spp. and Escherichia spp., respectively. Samples from Delta B hostel and Choba campus recorded the lowest and highest THB, TC and FC counts respectively. According to WHO standard, the result of THB, TC and FC counts indicated that the tap water in all eight locations were above the limit acceptable for drinking but within acceptable limit for other domestic use such as bathing and washing.
