One water sample was taken from every premises at each
sampling point. These were reported as being compliant or non
compliant with the CYS, APHA or ELOT standard according to the
parameter tested. Results for chemical standards were consistent
through out the study with 2% of the samples reported as noncompliant.
Results for microbiological standards showed a reduction
in non-compliant samples from 34% at stage one to 20% at
sampling points 4 and 5.
to 22 (8.8%) and 27 (10.8%) respectively. Although there were more
non compliances at the end of the process than there had been in
the beginning, these differences were not found to be statistically
significant.
