Water supply in selected villages in Katsina State-Nigeria

Bu makale, Nijeryanın Katsina eyaletinde bulunan dört köyün su kaynakları ve rezervi konusunda birrapor sunmaktadır. Dört köy (Kurechidutsi, Dogoruwa, Unguwar Mangoro ve Kwari) ziyaret edilmiştir. Su teminiile ile problemlere ilişkin veri toplandı ve incelenen alanda su kalitesinin varlığı ve biyo-mühendisliğine ilişkindeğerlendirmeler yapıldı. Bu bölgede, su kaynaklarından temin edilen saf ve arıtılmış suyun kalitesi, laboratuvardastandart 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) eşitoranda 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 sıklıklakarşılaşılan bakteri, %33.2 ile Enterobacter sp. olmuştur. Bu bakteriyi, karşılaşma oranı bakımından Klebsiellasp.(%17.5), Pseudomonas sp. (%17.1), ve Escherichia sp. (16.5%) bakterileri izlemiştir. Shigella sp. için bu oran10.1% olmakla birlikte en düşük oran Proteus sp. (5.6%) aittir. Bu çalışmada, kötü su kalitesi nedeniyle bir su re- zerv probleminin olduğu saptanmıştır.

Nijerya nın Katsine eyaletinde bulunan seçilmiş köylerin su rezervi

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 qualityin the area was conducted. The quality of raw and treated water from sources of water were measured at the siteand in the laboratory using standard methods and procedures. The study revealed that the predominant species ofthe 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 identifed based on their cultural and mor-phological characteristics. Eighteen different bacterial species belonging to six different genera were isolated fromthe water samples. The most frequently encountered bacteria were the Enterobacter sp. with 33.2% occurrencefollowed 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 thestudy that there is a water supply problem due to poor water quality.
