This study was aimed at the determination of
chemical and gross organic pollutants levels in leachates from some selected
and government approved dumpsites in Port Harcourt metropolis. Leachates from
the 3-selected dumpsites were analyzed and compared with the seasons, controls
and established standards using descriptive statistical designs. Integrated
samples were collected during both wet and dry seasons and analyzed for DO,
BOD, ORP, Salinity and pH. The use of 2-way ANOVA, t-test, graphs and mean
variation were applied to explain trend and variations. The results show that
there was no significant difference in temporal dimension (seasonally) but high
level spatial variation (stations) in most parameters occurred. Most chemical/
gross organic pollutants showed higher level concentrations during the dry
season. Though some of the parameters were relatively low compared to standard
limits; the study revealed that these dumpsites remain major polluting sources
to the surrounding surface and ground water regimes. In order to recover these
dumpsites from acute contamination, state government should ensure the use
active remediation processes and treatment to reduce the effects of pollution
to the ecosystem.
