Effect Of Refuse Dump On Underground Water Quality

ABSTRACT

The major source of water in EMENE, the study area is rain, streams and well water.

Waste management has been a problem in Nigeria and so many developing nations. Most

organic pollutant and pollute our underground waters. In this research, three wells were

reported polluted in the compound of Adedoyin school of preliminary studies, this

research was carried out to know if pollution was as a result of a dump site found inside

the compound. Well B was more closer to the dump site, followed by Well C and Well A.

The parameters analyzed are: Turbidity, pH, electrical conductivity, Nitrate, sulphate,

iron, calcium, chloride, coliform, total solids, magnesium, E-coli and Total dissolve

solids. The results showed that the wells were actually polluted but most of the

parameters fell within the permissible and desirable limit of WHO & NSDWQ. Coliform

test exceeded the limits in all the three wells sampled with maximum value of 300per

100ml, 110per 100ml and 130 per 100ml for well A, B, C respectively. Well B showed a

greater degree of pollutants within the days of sampling. Mathematical model performed

showed that Well B also gave a better R value for most of the parameters. Categorization

of the water sample was done using Canadian council of ministers of environment index

(CCME) the value for the whole sample analyzed falls was 75.5 and this value is within

the 65-79 which indicates that the water quality is usually protected but occasionally

threatened.
