The 7th and final screening clinic of Walkerton area residents ended today.
Residents who lived in Walkerton during the E. coli tragedy in May 2000 have been involved in more than four months of tests.
There has a been a health study every year since the disaster killed seven people and made more than two thousand others ill.
Clinical Co-ordinator Arlene Richards says they found more physical problems have developed in some residents who first appeared fine.
The results of this study will be released in the fall.
