The swimming pool at the Commonwealth Games has passed test for the quality of water, with officials revealing that the cause sickness among swimmers at the Games is still under investigation.

A number of swimmers from both England and Australia have been hit by a sickness bug which has affected several of their performances.

Commonwealth Games Federation chief Mike Fennell is concerned by this outbreak, but says that it is not down to the quality of water in the swimming pool.

Although it is good news on the water quality front, it is still a concern that they have not found the cause of the problem.

"Three pools were tested - at the village training pool, at the warm-up pool and at the competition pool - and the tests at all three pools revealed that the standard of the water was as required," said Fennell.

Doctor

"The CGF doctor has been in touch with the teams and they all agreed that the problems have not been caused by the water. They could have been caused by a number of other things.

"We are satisfied that we have made all the checks that are necessary on the water in the pools and the investigation into what is causing the problem goes on."

During his daily media briefing, Fennell also promised to investigate problems at the athletics track where Australian Sally Pearson was controversial stripped of a gold medal, just as she was about to receive it.

Pearson was all set to climb on to the podium to receive a gold medal when she finally learnt that a protest had been lodged.

Pearson's disqualification saw England's Katherine Endacott promoted to bronze but Fennell admitted she should have been notified of the appeal much sooner.

"It was a major communications blunder by the officials at the athletics," said Fennell. "Someone did not communicate to the athlete that a protest had been lodged. If you have protest athletes should be told and the reasons why."

Scoreboard

Asked about the collapse yesterday of a scoreboard at a Rugby Sevens training venue, Fennell said he understood it had been fixed in time for the tournament which starts on Monday.

Fennell also revealed that the CGF are concerned about TV coverage for the cycling road events and the athletics marathons as they are still seeking approval from Delhi authorities for TV helicopters to fly into restricted areas.

"We are endeavouring to get the restrictions waived," said Fennell.

Delhi 2010 organising committee secretary general Lalit Bhanot, standing in for chairman Suresh Kalmadi, was asked if the organising committee was competent to run the Games in the wake of the latest batch of problems.

"We are fully competent and we are running it efficiently," claimed a defiant Bhanot.

Fennell, having promised that the Games INFO system, which delivers results and other information to media, would be fixed yesterday, had to admit that problems were still not resolved and that a back-up system had been introduced in the meantime.
