Effluent samples were collected from main manholes
comprising raw wastewater from domestic, central business
area (CBA), industrial and the outfall point at sea, Osu beach.
The environmental effects of sewage pollution and wastewater
effluent quality management in the Accra Metropolis, Ghana
was assessed over a three month period. The physico-chemical
and bacteriological analysis were determined using standard
methods. The results of the physico-chemical parameters
values were; pH 7.3- 8.2; EC 1277 –56828 μS/cm; TDS 613-
28413 mg/l); BOD 3.8-53 mg/l; and the nutrients NO3-N ranged
from 1.5- 13.5 mg/l; NH 3-N,0.2-3.8 mg/l; PO43-0.6-6.4 mg/l. The
bacteriological analysis also recorded TC 6.6-5761 cfu/100ml:
FC 0.6-139 cfu/100ml and E.coli 0.3-34 cfu/1m respectively.
The level of compliance of effluent with the physico-chemical
and bacteriological parameters were all below the Ghana
Environmental Protection Agency (EPA) permissible standards
for wastewater discharge at the outfall point at the Sakumono
beach. Although, the nutrient levels were not too high, yet may
have the potential to cause eutrophication especially in the water
bodies that sewage overflow into such as Korle, Lavender Hill and
Odor lagoon and deplete the oxygen levels which will affect the
aquatic life. The results of the social survey analysis observed
some challenges with respect to the management of wastewater
in the Accra Metropolis. Eighty percent admitted environmental,
social and public health effects such as water borne diseases
such as malaria, typhoid, diarrhea, dysentery among others.
To prevent or reduce environmental effects and health risk
associated with wastewater and sewage pollution, adoption and
utilization of decentralized wastewater technologies that are
most economically useful and efficient for the tropics such as
waste stabilization ponds to safeguard public health and prevent
negative environmental effects.
