Microbial densities and physicochemical quality of some crude oil flow stations' saver pit effluents in the Niger Delta areas of Nigeria.

Five crude oil flow stations saver-pit effluents were sampled during the months of October, November, December and January to determine some of their physicochemical qualities and microbiological densities before their discharge into the environment. Standard analytical techniques were employed in the investigation. A high microbial density in the range of 10(6) cfu/ml was observed in the samples. The high coliform count obtained poses a potential threat to the local inhabitants of the area. The physicochemical qualities of the effluents appear to fall within or near acceptable standards. Nevertheless, adequate treatment of the effluent is required especially during the month of January before its discharge into the environment.
