Effluent (wastewater) were collected from a metal finishing company, Zaria -Nigeria over a period
of 2 years. Physical and chemical characteristics of the effluent were determined using standard methods.
The means of: pH (4.5), TD S (4348.00mg/l), TSS(395.00mg/l), NO3-N(84.50mg/l), SO42-(1992.67mg/l),
ClG(823.87mg/l), Cu(7.97mg/l), Pb(1.10mg/l), Ni (11.85mg/l) and Zn(5.06mg/l) were far outside the limits
set by FEPA for the discharge of wastewater from metal finishing company into surface water. Even though
FEPA limits does not include electrical conductivity, total alkalinity, total hardness, total solids, and dissolved
oxygen for this category of industry, the values of these parameters obtained for the company effluent samples
were obviously very high for wastewater to be discharged into surface w ater.
Key words: Wastewater, discharge, FEPA limits, metals , environment, degradation,
