5. New individual water supplies and water supply systems which have been
repaired or otherwise become contaminated are thoroughly disinfected before
being placed in use (see, PMO - Appendix D). The supply shall be made free
of the disinfectant by pumping to waste before any sample for bacteriological
testing shall be collected.

6. All containers and tanks used in the transportation of water are sealed and
protected from possible contamination. These containers and tanks shall be
subjected to a thorough cleaning and a bacteriological treatment prior to filling
with potable water to be used at the dairy farm.

To minimize the possibility of contamination of the water during its transfer
from the potable tanks to the elevated or ground water storage at the dairy
farm, a suitable pump, hose and fittings shall be provided. When the pump,
hose, and fittings are not being used, the outlets shall be capped and stored in
a suitable dust proof enclosure so as to prevent their contamination.

The storage tank at the dairy farm shall be constructed of impervious material
provided with a dust and rainproof cover, and also provided with an approved
type vent and roof hatch. All new reservoirs or reservoirs which have been
cleaned shall be disinfected prior to placing them into service (see, PMO -
Appendix D).

7. Samples for bacteriological examination are taken upon initial approval of the
physical structure, based upon the requirements of this Ordinance and when
any repair or alteration of the water supply system has been made, and at
least every three years. Provided, that water supplies with buried well
casing seals, installed prior to the adoption of this section, shall be
tested at intervals no greater than 6 months apart.

Whenever such samples indicate either the presence of bacteria of the
coliform group, or whenever the well casing, pump or seal need replacing or
repair, the well casing and seal shall be brought above the ground surface
and shall comply with all other applicable construction criteria of this Section.

When water is hauled to the dairy farm, such water shall be sampled at the
point of use and at least four times in separate months in any
consecutive six months, for bacteriological examination at the point of use
and submitted to an approved laboratory each month. Bacteriological
examinations shall be conducted in a laboratory acceptable to the regulatory
agency.
