Other seven locations popular with locals have high concentrations of harmful bacteria due to sewage and livestock
Only one popular river spot for bathing and water sports in and around Oxford has bacteria within safe levels, a survey by a campaign group has found.
The other seven locations in rivers which are regularly used by swimmers, punters, rowers and kayakers, were found to have concentrations of harmful bacteria one and a half to three times above recommended safe levels, a study by the Oxford Rivers Project funded by Thames Water has found.
