The results of the bacteriological examination of the raw
waters were typical of waters derived from the Chalk, some of
which showed the normal deterioration in quality which occurs
after heavy rainfall. In all cases the results indicated that
the waters were suitable for treatment. Bacteriological examinations
of the treated waters indicated that these were of
uniformly satisfactory quality.
(b) Chemical Analysis.
The arrangements for chemical analyses are simiiar to those
for bacteriological examinations. The total numbers of samples
analysed in the laboratory of the Water Undertaking and by the
Consultants were 89 samples of raw waters and 114 of treated
waters going into supply. The results of these analyses were
uniformly satisfactory.
For results of samples tested by the Public Health Laboratories
see Appendix page 127.
