Cumulative effect on treated sewage discharge on channeled barge sloot

Abstract

A study was initiated to establish the cumulative effect of treated sewage discharge on channeled barge slot. Water and sediment samples from the barge slot were collected weekly for twelve months and physico-chemical characteristics of the samples were monitored. General characteristics of aquatic habitats of the slot were also studied. The results were compared with results of water samples and aquatic habitats collected from 500 m and 1000 m away from the barge slot. Tissue analyses results show that the fishes in the barge slot are rich in proximate and mineral content than fishes of the same species from the 500 m and 1000 m distance away from the barge slot. Physico-chemical results of the treated sewage are all within acceptable limit for discharge into water body while results of water samples from the barge slot showed no sign of pollution or distortion in fauna and floral life of the slot. However, the dissolved oxygen level was quite low when compared with samples collected from the other two sources. Coliform count and ammonia (indices of faecal contamination) were also found to be higher in the barge slot.
