City Health Dept. Reports 93 Dirty Pasadena Swimming Pools, Possibly Mosquito Breeding Sites, Cleaned or Emptied

City authorities and staff from the San Gabriel Valley Mosquito and Vector Control District identified a total of 93 dirty swimming pools in Pasadena that could be breeding places for mosquitoes, including those that carry the West Nile virus and other diseases.

The owners of these swimming pools were notified and advised to clean them and restore them to a functional state, or to empty the water and keep the pools dry.

A report by Michael Johnson, the City’s Director of Public Health, said the dirty or “green” pools – green because of algae – were identified in the spring. The owners were given Swimming Pool Notices, and by August all the pools have been cleaned, Johnson said.

According to the San Gabriel Valley Mosquito and Vector Control District, a dirty and unmaintained swimming pool can produce up to three million mosquitoes in a month, contributing to the spread of mosquito-borne diseases.

The District said only two conditions could guarantee that mosquitoes don’t grow in the swimming pools: they should either be “clean and functional,” with a working filtration system, or “empty and dry.”

The District sends out two types of notices to swimming pool owners: a Violation Notice, or a Confirmation Request. Both notices require the owners to report that their pool is clean and functional, or empty and dry.

Property owners are given a deadline to correct the problem, and once the pool is returned to an acceptable state, the owner should send a photo of the pool and the notice to the District by text or email.

Pools that are filled with clean water and maintained with sanitizer and a working filtration system are considered corrected. Pools that are drained dry are enrolled in a confirmation program, where owners are required to submit a photo confirmation on  regular basis, since dry and drained pools can easily become a mosquito breeding source a few days after rain.

Under the Vector District’s mosquito control program, residents are encouraged to report a pool suspected of breeding mosquitoes by calling (626) 814-9466.
