Geoff Goss' son Aaron, 17, of Rushden, went missing on July 26, 2006, while he was swimming with friends in the Anzu river in the country's Tena region.

Aaron's death prompted Northamptonshire County Council to review its safety guidelines and effectively ban pupils from swimming in natural waters during school trips.

But now Mr Goss has been asked by the Government to help draw up new national guidelines to protect pupils.

He said: "I'm hoping to have some input into introducing practical swimming tests for pupils on all school trips involving swimming and other water-based activities.

"All I can hope for is that lessons are learned and the circumstances leading to Aaron's death will not be repeated."

In the aftermath of the tragedy, Aaron's family set up two funds in his name, which together have now raised more than £65,000.

The money is being used to help the Clarita Luz children's home where Aaron worked shortly before his death, and the firefighters who found his body, after a five-day search, 60 miles downstream from where he disappeared.

It has so far provided a much-needed fire engine and medical and firefighting equipment for the Tena firefighters.

It will also furnish a new house at the orphanage which will include three dormitories for girls, three bathrooms specially designed for small children, and a light area where the children can eat and do their homework.

When it is officially opened it will be called Casa Aaron.

Some of the money also provided a climbing wall for Wollaston School, where Aaron was a pupil.

The latest fundraiser in Aaron's memory was a weekend of live music at the Wheatsheaf pub in Rushden, which was held on Friday and Saturday.

Mr Goss said: "It's so nice to see Aaron's friends and family are still happy to be involved in raising money for such a worthy cause.

"We would like to thank everyone for their generosity and support."
