Nijerya’nın Katsine Eyaletinde Bulunan Seçilmiş Köylerin Su Rezervi

Bu makale, Nijerya’nın Katsina eyaletinde bulunan dört köyün su kaynakları ve rezervi konusunda bir rapor sunmaktadır. Dört köy (Kurechidutsi, Dogoruwa, Unguwar Mangoro ve Kwari) ziyaret edilmiştir. Su temini ile ile problemlere ilişkin veri toplandı ve incelenen alanda su kalitesinin varlığı ve biyo-mühendisliğine ilişkin değerlendirmeler yapıldı. Bu bölgede, su kaynaklarından temin edilen saf ve arıtılmış suyun kalitesi, laboratuvarda standart metod ve prosedürler kullanılarak ölçüldü. Çalışmada, en etkili mantar türlerinin; Aspergillus sp (%33.3), ve Penicillium sp, Rhizopus sp, Mucor sp, Neurospora sp, Fusarium sp ve Botrytis sp.nin her birinin (%12.5) eşit oranda tespit edildiği gözlenmiştir. Bu mantarlar, geçici olarak kültürel ve morfolojik özelliklerine göre tanım- lanmıştır. Alınan su örneklerinden, altı farklı cinse ait olan 18 farklı bakteri türü izole edilmiştir. En çok sıklıkla karşılaşılan bakteri, %33.2 ile Enterobacter sp. olmuştur. Bu bakteriyi, karşılaşma oranı bakımından Klebsiella sp.(%17.5), Pseudomonas sp. (%17.1), ve Escherichia sp. (16.5%) bakterileri izlemiştir. Shigella sp. için bu oran 10.1% olmakla birlikte en düşük oran Proteus sp. (5.6%) aittir. Bu çalışmada, kötü su kalitesi nedeniyle bir su re- zerv probleminin olduğu saptanmıştır.

Water Supply in Selected Villages in Katsina State-Nigeria

This paper presents a report on water resources and water supply of four villages in Katsina state, Nigeria. The four villages (Kurechidutsi, Dogoruwa, Unguwar Mangoro and Kwari) were visited. Data were col- lected on the magnitude of water supply problems, the existence and bio-engineering assessment of water quality in the area was conducted. The quality of raw and treated water from sources of water were measured at the site and in the laboratory using standard methods and procedures. The study revealed that the predominant species of the fungi was Aspergillus sp having 33.3% occurrence and 12.5% each of Penicillium sp, Rhizopus sp, Mucor sp, Neurospora sp, Fusarium sp and Botrytis sp. The fungi were tentatively identi ed based on their cultural and mor- phological characteristics. Eighteen different bacterial species belonging to six different genera were isolated from the water samples. The most frequently encountered bacteria were the Enterobacter sp. with 33.2% occurrence followed by Klebsiella sp.(17.5%), Pseudomonas sp. (17.1%), and Escherichia sp. with 16.5% occurrence each. Shigella sp. has 10.1% occurrence while the Proteus sp. has the least with 5.6% occurrence. It was concluded in the study that there is a water supply problem due to poor water quality.
