A poorly sorted nature of particle sizes may
indicate soil not formed from natural process of
weathering of the underlying parent material but
rather, from the deposited wastes (Okoronkwoet
al., 2006).

Consequently, the frequency of occurrence of the
microbial isolates can be influenced by the soil
particle content which has been altered by the
waste being disposed at the dumpsites.
