Public Swimming Pools

BEDHD inspects public swimming pools to achieve the following objectives:

  • Establish operator competency through audits, education, and certification.
  • Minimize the risk for swimming-associated illnesses, injuries, or deaths.
  • Assure facility contingency plans for response to biohazard (blood, feces, vomit) events at or in the pool.
What Is a Public Swimming Pool?

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) swimming pool rules define a public swimming or spa pool as "an artificial body of water … used for the purpose of swimming, wading, recreation, or instruction." Facilities having public pools consist of schools, hotels, apartments, campgrounds, hospitals, fitness centers, condominiums and neighborhood association, etc.

BEDHD currently audits 73 public swimming pools and spas on a semi-annual basis for safety and environmental hazards. All outdoor pools must have a pre-opening audit prior to opening for the season.

Certified Pool Operators

It is recommended that a certified pool operator (CPO) be the person responsible for operating and maintaining a public swimming pool or spa. Certification is achieved through the National Swimming Pool Foundation (NSPF) and is valid for five years. Additional information on CPO certification can be found on the NSPF website.

Since 2003, BEDHD has been annually monitoring the surface water quality at various public bathing beaches within the district through the grant source of the Clean Michigan Initiative-Clean Water Fund (CMI-CWF). This monitoring is aims to:

  • Minimize the risk of swimming-associated illness.
  • Increase public awareness of waterborne diseases.
  • Increase park officials’ education and the monitoring and maintenance of publicly used beaches.
What Is a Public Bathing Beach?

A bathing beach is defined as an outdoor public area along a natural or man-made body of water for the intended purpose of recreational use and/or swimming.

Beach Sampling

Each beach is sampled at 3 separate locations at a frequency of 5 times per month. If a beach water sample is found to have above 300 E. coli per 100mL of water, or if the 30 day geometric mean at a sample site is above 130 E. coli per 100mL of water, a swimming advisory will be posted for not meeting Michigan water quality standards for full body contact. A swimming advisory will remain in effect until follow-up samples indicate the water meets the full body contact standards.
