(AP) — Lincoln City Council members are considering a measure that would require training, testing and certification of anyone who checks public swimming pools for quality standards.

Last year the city had to close 133 pools during inspections because the water didn’t meet quality standards.

City inspectors think that people doing the testing often don’t do it correctly or don’t know what to do when a problem surfaces.

The City Council is scheduled to hold a public hearing Monday on the proposed changes in pool regulations.
