Swimming pools below standard

According to an investigation by Members of the Institute of Sport and recreational Management, commissioned by Consumers’ Association Magazine Which? , many swimming pools fall below acceptable health standards. Measure of bacterial content in water samples showed that more than half of the 61 examined fell below acceptable standards and nine posed potentially serious health risks. Spa pools were a worse hazard than swimming pools, one having bacterial content 30 times in excess of the maximum recommended safe level.
