The physicochemical parameters of the water were analysed prior to dredging and most of the values obtained were within acceptable limit of established water standards. The samples were collected from 5 stations: station 1 was the dredging point, stations 2 and 3 were 250m and 500m upstream of the point, while and stations 4 and 5 were 250m and 500m downstream of it respectively.
Water samples were collected prior to, during and monitored several months after dredging. The study was carried out from July 2010 to January, 2012. A study was done to ascertain the effect of hydraulic dredging and spoils disposal on the physicochemical parameters of Nworie River.
