A spokesperson from the Scottish Environment Protection Agency (SEPA) said:
SEPA has taken further investigatory samples at North Berwick (West) bathing water this week after a previous sample (taken on 15 August) showed a level of pollution to be present.
“SEPA’s analysis of these latest samples has shown that there has been a return to more typical water quality over the past two days. Based on these latest results we can confirm that the previous short term pollution is no longer affecting bathing water quality at North Berwick (West) and the temporary advisory notices will be removed by East Lothian Council.
“We have been unable to conclusively determine the source of the previous result, however we are continuing to work with our partner organisations to help prevent any potential sources of pollution.”
