The results reported in this work are site
specific as it dealt with the variability of water quality parameters through
three distribution systems A, B and
C in Afikpo North local government area of Ebonyi State,
Nigeria. Water quality parameters in these distribution systems were analyzed
using coefficient of variation and the Pearson’s coefficient of correlation.
System
B showed highest level of recontamination followed by system *A, while system
*C indicated the least level of recontamination. This
inference was made based on the overall results from their coefficient of
variation. Pair wise comparison was carried out on the distribution systems.
Result showed that regression of *A on *B gave an r-value of -0.114, a very low affinity between the
two and hence evidence of strong variability and substantial difference between
the degree of recontamination between them. The result of regression of
A on *C was 0.283 indicating recontamination but with closer
relationship, while the regression of
*B on *C was 0.613, this is a very sharp contrast between the two
distribution systems, which implies that recontamination is very high relative
to each other.
