[Ord. No. 07-110 §1, 8-14-2007]
Aquatic center water shall be treated and maintained so that
whenever the aquatic unit is open for use, the bacterial, chemical
and physical quality of the water meets the standards set forth in
this code.
[Ord. No. 07-110 §1, 8-14-2007]
An operator of a public or semi-public aquatic center shall
ensure that the aquatic unit is filled only with potable water from

A.
Not
more than fifteen percent (15%) of the water samples collected from
a pool shall:
1.
Contain more than two hundred (200) bacteria per milliliter as determined
by the standard (35°C [95°F]) agar plate count, or
2.
Show a confirmed positive test for coliform organisms in any of the
five (5) to ten (10) milliliter portions of a sample or more than
one (1) coliform organism per fifty (50) milliliters when the membrane
filter test is used. All samples shall be collected, dechlorinated
or similarly neutralized when another disinfectant is used and examined
in accordance with the procedures outlined in the latest edition of
"Standard Methods for the Examination of Water and Wastewater". The
department may collect or require the owner to collect and submit
water samples at cost for bacteriological examination on a routine
basis while it is in active use.
[Ord. No. 07-110 §1, 8-14-2007]
A.
Aquatic
units shall be continuously disinfected by an approved means, which
will maintain an adequate and readily measurable residual of disinfectant
in the water.

The procedure for determination of free chlorine residual shall be
by the DPD method or any of the other procedures outlined in the latest
edition of "Standard Methods for Examination of Water or Wastewater".
[Ord. No. 07-110 §1, 8-14-2007]
A.
The
surface of the pool water shall be kept free of scum and floating
debris. The bottom and sides shall be maintained free of sediment,
dirt, slime and algae. Water shall be maintained free of turbidity
and shall be sufficiently clear so that the main drain outlet is clearly
visible to an adult standing on the pool deck or that a Secchi Disk
two hundred (200) mm in diameter when placed at the bottom of the
pool at the deepest point is clearly visible to an adult standing
on the pool deck.
B.
The
temperature of heated water coming into an aquatic center shall not
exceed one hundred four degrees Fahrenheit (104°F) (forty degrees
Centigrade (40°C)).
[Ord. No. 07-110 §1, 8-14-2007]
All pools and spas shall be equipped with approved test equipment
to determine pH, disinfectant residual, total alkalinity and temperature.
The chemical disinfection level, pH, total alkalinity and temperature
of the water shall be tested at least once daily. Log shall be on
the premises and an operating log that includes the results of these
tests shall be maintained for twenty-four (24) months and made available
to the department, any other regulatory authorities or a member of
the public upon request
[Ord. No. 07-110 §1, 8-14-2007]
Should a fecal accident occur, the pool operator or owner shall
consider the Centers for Disease Control's (CDC) "Fecal accident response
recommendations for pool staff" found on the Internet web site: http://www.cdc.gov/healthyswimming/fecalacc.htm.
