SWIMMING POOLS

WHERE WE SAMPLE:   Any public location that has a swimming pool.  This includes schools, hotels, mobile home parks, apartment complexes and campgrounds.

WHEN WE SAMPLE:  Samples are submitted to our office or a certified laboratory from these establishments every Monday.  Outdoor pool locations submit samples only during the weeks when the pool is open.  Prior to a seasonal outdoor pool opening each year an annual opening inspection must be completed. 

SAMPLE RESULTS:  The weekly results will not be posted on the Monroe County website.  If a pool has water quality results that are above the acceptable limits they will be notified by phone and another sample requested for re-testing.  If the result from the re-sample is still above acceptable limits, the pool will be closed by the Monroe County Health Department until maintenance and re-sampling indicates the water quality is within acceptable limits.

INSPECTIONS:  The Michigan Department of Natural Resources and Environment requires one inspection per year be conducted at each public pool.  Some of the items observed during the annual inspection are:  water quality and clarity, safety equipment, (backboard with straps, first aid kit, emergency phone, lifeline, buoy, etc.)  no diving signs, pool rules and bather load limit.

FREQUENTLY ASKED QUESTIONS ABOUT POOLS

1.  If I think there is a water quality or safety concern at a public pool, what can I do?
Call the Environmental Health Division. A sanitarian will investigate the complaint and determine what action must be taken.

2.  How does spa water differ from pool water?
Spa water is at a much higher temperature than pool water.  Spa water is 104ºF.  Also there is a much smaller volume of water in a spa than a pool.  The low volume and higher water temperature require very close monitoring of the chemical and ph balance in a spa.

3.  What are the most common pool water sanitizers?
Chlorine and bromine are the most common chemicals used to sanitize pool water.  All public pools are required to submit to the Monroe County Health Department monthly operational reports which list the pH and sanitizing levels present in the pool each day of the month.
