Untreated sewage effluence is referred as those domestic and industrial
waste effluents which are discharged into septic tank or sterilization
pond and have not undergone treatment process. This untreated sewage
effluent contains heavy metals such as sulphur, zinc, copper and other
toxic metals. (Kharche, et al, 2011)
Effluent from Municipal sewage
treatment plants often contain high level of plant nutrient,
particularly nitrogen and potassium, which are essential to crop growth.
Agricultural application of untreated sewage effluent provides both
water and nutrient for crop production (Chambers, et al, 2002). However,
depending on the content of the potentially harmful component, which
can accumulate in the soil of the farm land biologically prove hazardous
(Rattan et al, 2005). Therefore when untreated effluent of the sewage
is used on land for an agricultural purposes, the problem associated
with its use should be considered (Emongor and Ramolemana, 2004). The
continous use of untreated sewage effluent on farm lands by farmer may
result in the accumulation of heavy metal on the soil and thereby affect
the soil fertility.
Therefore, the need for farmer to know the
effect of untreated sewage on farm land is a necessity especially, in a
developing country like Nigeria were farmers have limited access to
chemical fertilizer.
Therefore, this study shall evaluate the impact
of untreated sewage effluence on farm lands using Sancaros Farm, Ihe
town in Awgu Local Government Area of Enugu State as a point of
reference.
1.2 Objectives of the Study
The project aimed at
evaluating the impact of untreated sewage effluent on farm land using
Sancaros Farm, Ihe town in Awgu Local Government Area of Enugu State as a
case study.
The specific objectives are:
(1) To characterize soil from farmland with sewage effluent deposit
(2) To compare the soil properties of farmland with effluent deposit with that without effluent deposit
(3) To highlight the negative effects of farmland with effluent to crops and possible recommendations for improvement
1.3 Justification of the Study
The
significant of the project cannot be over emphasized. The need to
understand the characteristic and composition of farm land with
untreated sewage effluent is a necessity.
Also these will serve as a
research material for agricultural industries and student on the
knowledge and understanding on the use of untreated sewage effluent for
agriculture. The result of this study may enhance farmer decision to
apply untreated sewage effluent instead of relying on prohibitive supply
of chemical fertilizer.

ABSRACT - [ Total Page(s): 1 ]This project is focused on the evaluation of the impact of untreated sewage effluent on farm lands. The use of sewage water for irrigation improved chemical properties and fertility status in soil.Sewage water contains elements essential for plant growth and also contains heavy metals which maybe toxic for animals if their concentration exceeds the permissible limit.To monitor this situation, a survey was conducted to ascertain the addition of heavy metals into agricultural fields through sewage ...
