VSP 2018 Operations Manual

6.3.2.1.1 Residual (09 C)
A free residual HALOGEN in the range detailed in the table below
must be maintained in recirculated RWFs.

RECREATIONAL WATER Free HALOGEN Residual,
FACILITY MG/L (ppm)
SWIMMING POOL ≥ 1.0 and ≤ 5.0
CHILDREN’S POOL ≥ 1.0 and ≤ 5.0
WADING POOL ≥ 1.0 and ≤ 5.0
INTERACTIVE RWF ≥ 2.0 and ≤ 5.0
(ACTIVITY POOL)
BABY-ONLY WATER ≥ 3.0 and ≤ 10.0 free chlorine
FACILITY ≥ 4.0 and ≤ 10.0 bromine
WHIRLPOOL SPA and ≥ 3.0 and ≤ 10.0 free chlorine
SPA POOL ≥ 4.0 and ≤ 10.0 bromine

For facilities that meet the definition of more than one type of
RWF, the more protective HALOGEN residual applies. For
example, if a CHILDREN’S POOL also has features of an
interactive RWF or ACTIVITY POOL, the HALOGEN range
must be 2.0 to 5.0 MG/L (ppm). Finally, if a facility is modified,
the most-protective HALOGEN residual applies.

6.3.2.1.2 pH (09 C)
The pH level in all RWFs must be maintained between 7.0 and 7.8.
Facilities not maintained within these HALOGEN and pH ranges
must be immediately closed.

6.3.2.1.3 Maintenance (10)
Halogenation and pH control systems must be maintained in good
repair and operated in accordance with the manufacturer’s
recommendations.

6.3.2.1.4 Procedures for Water Sampling (10)
Manual samples from the RWF tub must be compared to the
analyzer samples in the pump (mechanical) room to assess
potential water quality differences in the RWF.

Recommended manual sampling procedures—All samples should
be obtained from a location with the following qualities:
• At least 18 inches (45.7 cm) below the surface of the water,
and
• At water depth of between 3 and 4 feet (91.4 cm to 1.2 m)
when available, and
• Between water inlets.
