times a day and logged Chlorine: combined, total, and freepH
Any chemicals added should also be written down in the log sheets along with the amounts added
Routine maintenance or repairs need to be logged as well
Safety Requirements: Chemical Storage
Rule of Thumb: Store like chemicals with like chemicalsStore acids separate and away from basesNever re-use chemical containers, especially to store
other chemicalsNever use the same scoop or utensil for different
chemicalsNever use the same cloth to clean up spillsStore on a non-absorbent surface
STORE IN ACCORDANCE TO MANUFACTURER’S LABEL
Water Quality Standards
Chlorine, Free and Combined
Free chlorine residual of at least 1.5 mg/l for a pH of 7.2 to 7.5 shall be maintained throughout the pool.
For higher pH values, higher free chlorine residuals of at least 0.2 mg/l for each 0.2 pH unit increase shall be maintained.
Total at least 1.5 ppm and not more than 5 ppm1 ppm = 1 mg/l
pH Maintained between 7.2 and 8.2
Combined ChlorineIf the concentration of combined
chlorine greater than 0.2 ppm, than the pool should be super chlorinated to reduce the concentration of combined chlorine
Superchlorination (46-161.f.1): free chlorine raised between 5 to 10 ppm.
Swimmers are not allowed back in until residual below 5 ppm
BromineWhen Bromine is used as a disinfectant, a residual
of 1 ppm shall be maintained for a pool with a pH below 7.8
2 ppm for pH 7.8 or higher
Water Clarity
Swimming pool water shall have sufficient clarity that the main drain cover is readily visible at the deepest point of the pool when viewed from the side of the pool.
A black drain cover or two-inch circle around the drain cover.
Transparency Disk Must be readily visible
Clarity
Algae Control
An algaecide may be used as long as it is in accordance with the label.
TemperaturePool water should be between 72 F and 85 FAir temperature for an indoor swimming pool should
be maintained from two to five degrees F above the pool temp.This helps with the humidity and also comfort of
swimmers Spa temperature not over 102 F
Pool CleaningRecommended pool and deck be cleaned, the pool
water surface skimmed, and the pool walls and bottom vacuumed or brushed, all on a daily basis and while the pool is closed for use.
TurnoverPool water turnover at least every 6 hours (4 times
a day)Wading pools must turnover a minimum of every 2
hoursA flow meter shall be provided to determine flow
rates and turnover rates

Chemical Safety: BRENT 10 minutes
Troubleshooting Brent will discuss common problems with pools and
how to bring your pool into compliance
Recreational Water Illnesses (RWI’s)Diseases that are transmitted through recreational
use of water including waterslides, swimming pools and lakes.
Some infect the gastro intestinal and respiratory tracts while others infect skin, ears, and eyes
9 Steps to Prevention of RWI’s
LeadershipEducationCommunicationWater QualityDisinfectionFacility DesignPlanningPreventionHealthy Swimming
Lead Your StaffMaking a choice to integrate an RWI protection plan
into an existing facility risk management plan is the single greatest decision you can make to protect swimmers from RWI’S
Educate Pool staffEnsure that all staff know the critical role of water
testing, proper testing methods, and how to respond if disinfectant levels are not adequate.
Develop Partnerships
Building a communication bridge to your health department and other aquatic facilities is a great way to get information about other outbreaks occurring in your community.
Educate Swimmers and ParentsRemember that people care about their health, so a lead-
in might be: “To ensure the health and safety of all our visitors, we ask that you remember to follow these easy
“ P-L-E-As” for Healthy Swimming.” Please don’t swim when you have diarrhea.Please don’t swallow the pool waterPlease practice good hygienePlease take your kids on bathroom breaks oftenPlease change diapers in a bathroom, not at poolsidePlease wash your child thoroughly (especially the rear end)
with soap and water before swimming
Maintain Water Quality EquipmentKeep the chemical feed equipment and chemicals at
optimal levels.Poor pH control can compromise chlorine’s
effectiveness as a disinfectant.Ensure regular and thorough maintenance of the
recirculation and filtration equipment to provide maximum filtration.
Institute Disinfection GuidelinesHave a written fecal accident response policy and
keep records of all fecal accidents, chlorine and pH level measurements, and any major equipment repairs or changes.
http://www.cdc.gov/healthyswimming/fecalresponse.htm
Evaluate Hygiene FacilitiesIn CDC’s parent interviews, parents uniformly said
they changed diapers at poolside because changing rooms were unclean, poorly maintained, and/or had inadequate diaper-changing facilities.
Create a Special Policy for Large Groups of Young ChildrenIf you allow large groups of diaper/toddler-aged
children in the pool consider:Requiring RWI orientation training for the care
providers and make sure they understand that your pool, like most daycare centers, also excludes children ill with diarrhea.
Keeping diaper/toddler-aged children in the pools specifically designated for them.
Post and Distribute Health InformationEncourage swimmers to shower with soap and
water before entering the pool.Post the six “P-L-E-As” that promote Healthy
Swimming.
Develop an Outbreak/Emergency Response PlanThe best advise is to be prepared. If an outbreak does occur, are you ready? Do you have a plan?Collaborate with your local health department.Support the investigation, it can lead to better illness
prevention strategies that can help everyone.
Cryptosporidiosis “Crypto”During the past two decades, Crypto has become
recognized as the most common cause of RWI’s in the United States.
Causes diarrhea and respiratory infectionsProtozoa found in infected people’s stoolCannot be seen by the naked eyeSurvives for a long period of timeResistant to chlorine disinfectionTakes approximately 6.7 days to kill in chlorinated
swimming pool
Escherichia Coli 0157:H7BacteriaCauses severe diarrhea and abdominal crampsCan lead to hemolytic uremic syndrome the principal
cause of acute kidney failure in childrenChlorine is very affective in killing E. coli 0157:H7 , <
1 minute
E.Coli 0157:H7
Giardia (gee-ARE-dee-uh)A protozoan infection principally of the upper small
intestineFound in infected peoples stoolCannot be seen by the naked eyeTakes approximately 45 minutes for properly
chlorinated water to kill
Giardia
NorovirusNoroviruses are a group of viruses that cause the
“stomach flu,” or gastroenteritis (GAS-tro-en-ter-I-tes), in people.
Found in the stool or vomit of infected peopleVery contagious and can spread easily from person
to person
ShigellosisDisease caused by a group of bacteria called
ShigellaInfects the GI tract Characterized by diarrhea accompanied by fever
and nausea, vomiting and crampsPresent in infected individuals stools while they are
sick and for a week or two afterwards
Shigella
Pseudomonas aeruginosaDermatitis/FolliculitisPathogenic Bacteria
Hot Tub Rash
Be aware that hot tubs and spas have warmer water than pools, so chlorine or other disinfectants break down faster
LegionellosisLegionnaires’ disease and Pontiac fever are caused
by Legionellae bacterium. Symptoms include anorexia, malaise, myalgia,
headaches, rapidly rising fever and chills. Temperatures commonly reach
102° F - 105° F.
Legionella bacterium
Other InfectionsSwimmer’s ear (ear ache) is an infection caused by
Pseudomonas aeruginosa.Swimmer’s itch, also called cercarial dermatitis,
appears as a skin rash caused by an allergic reaction to certain parasites

Plan SubmittalPlease consult your inspector before making
changes to your pool!Please submit your plans of action for coming into
compliance and have your inspector approve it before making big purchases or changes to your pool!
Please keep all information, documentation, and certificates of compliance on hand at the facility.
How do I know my pool or spa is in Compliance???Step 1: Does my drain comply with the VGB Act?
They must be marked with
VGB 2008
ASME/ANSI A112.19.8 2007 or logo
Flow Rate
Life Span
Drain CoversIf field fabricated, must by certified by a Registered
Design Professional (Professional Engineer) who provides a copy of a certificate saying it meets the VGB Act Standards, including flow rates, UV exposure, and durability
Is it secure and installed according to manufacturer’s instructions?
Is my pool in compliance?Step 2: Do you have secondary back up options?
Do you have more than 1 main drain going to single pump? (MUST BE 3 FT DISTANCE FROM CENTERS)
If you have a single main drain?Did you get an SVRS (Safety Vacuum Release System)Do you have and automatic shut off?Do you have a suction-limiting vent system?Is your drain unblockable?Is your drain gravity fed?Did you disable your main drain? (if you did, did you
provide flow rates or turnover rates to show you meet local code?)
Secondary SystemsSVRS: A safety Vacuum release system which
ceases operation of the pump, reverses the circulation flow, or otherwise provides a vacuum release at the suction outlet when a blockage is detected, that has been tested standard by an independent third party and found to conform to ASME?ANSI standard A112.19.17 or ASTM F2387
Automatic Pump Shut Off System: An automatic pump shut-off system
Secondary Systems Suction-limiting Vent System: A suction-limiting vent
system with a tamper-resistant atmospheric opening.Unblockable: means a drain of any size and shape
that a human body cannot sufficiently block to create a suction entrapment hazard.(from CPSC interpretation)ASME/ANSI A112.19.8 standard of unblockable-
Dimensions of 18’’ x 23”, which represents shoulder to waist measurements of the 99th percentile of adult males.
Secondary SystemsGravity Drainage System: A gravity drainage system
that utilizes a collector tank.Drain Disablement: A device or system that disables
the drainONLY IF YOUR INSPECTOR APPROVES IT!!!!!YOU MUST MEET LOCAL CODE TURNOVER AND
FLOW RATES!!!! Turnover Rates Every 6 hours (4x a day) for pools Every 2 hours for wading pools and spas
Secondary SystemsOther Systems can be used but must be determined
by the CPSC as equally effective or better than the ones outlined in the VGB Act.
NO DRAIN REVERSALS! (These are not permanent and the department is not approving them)
If you answered no…Than grab a card of your inspector and call and set
up a consult.
YOU MUST MEET ALL REQUIREMENTS OF THE VGB ACT AND LOCAL CODE TO OPEN YOUR POOL.
Questions?Thank you for attending.Please turn in surveys now if you haven’t already.
Make a consult with your inspector if you have specific or detailed questions about your specific pool.
Have a Great Day!!!!
