The quality of Amba River in Nasarawa State in the North Central Nigeria was investigated for a period of one year covering dry and rainy season. Water samples were collected from four different locations (Gandu, Wadatan-Waje, Kofan-Kaura and Unguwan-Galadima) along the river course and analyzed for Bacteriological parameter, using standard methods. The results indicated seasonal variation in coliform population with higher values at Wadatan-waje and Unguwan-galadima during rainy season. The values obtained for coliform on the average for the two seasons were beyond the maximum acceptable standard set by the World Health Organization (WHO, 2004) for drinking water. Thus, settlers along the River should be enlightened on the danger of consuming untreated water from the River. Also, measures at regulating the pollution of the River should be taken for a healthy and vibrant community.
The objective of this research was to evaluate bacteriological and parasitological pollution levels of soil, groundwater, surface water and river sediment in the vicinity of a pig farm. The microbiological examinations of soil and water environment within the pig farm area and around it showed considerable pollution with animal droppings and municipal sewage coming from a breeding farm and farm buildings. This was confirmed by the results of examinations based on isolation of bacteria that make intestinal natural microflora: Escherichia coli, Clostridium perfringens and enterococcus. In the soil environment there were also determined bacteria Salmonella sp., Bacillus subtilis, Pseudomonas sp., Proteus sp., Klebsiella sp., Micrococcus sp., Enter obacter aerogenes, Citrobacter sp.y and Corynebacterium sp., as well as fungi of Candida genus. The soil within the farm and around it was infected with eggs and larvae of worms of Strongylidae and Trichostrongylidae genus, eggs of nematodes of Trichuris genus, Ascaris suum eggs and oocysts of Eimeria genus. Despite a systematic animal disinfestation at the yard for gilts and boars there still occurred great quantities of parasites.
This paper presents results of bacteriological investigations concerning coastal seawater and sandy sediments in the Three-city region at the outlet of four streams: Kacza (KaS), Swelina (SwS), Grodowy (GS) and Kamienny (KmS). The numbers of facultative psychrophilic bacteria, mesophilic bacteria and indicator bacteria (coliforms, fecal coliforms, fecal enterococci) were determined. It was found that all streams are carrying fecal bacteriological pollution of human and animal origin which contributes to poor quality of coastal seawater and sandy sediments. The lowest sanitary quality was KaS water, where the number of all indicator bacteria, as a rule, exceeded admissible levels. In sandy sediments of the estuaries of all four streams the average number of indicator bacteria was about one order of magnitude higher than in water. Enterococcus was the bacterial indicator that exceeded single water or sediment sample standards most often.
