Tests of well water earlier this month at the Alder Flats school, about 160 kilometres southwest of Edmonton, revealed the presence of E. coli bacteria, the family of bacteria that killed seven people in Walkerton, Ont., in 2000. Similar tests taken at Lakedell school, in Westerose south of Pigeon Lake, indicated the presence of coliform bacteria.
