Grade 10 students in Pierson, Manitoba, were given a well-testing project in a horticultural and environmental studies class. Of 20 samples submitted for analysis, 12 came back with unacceptably high bacteria or nitrate levels. Another testing by a local conservation district showed 70 per cent of wells tested was contaminated. A number of the samples were well above 200 colonies of bacteria per 100 millilitres of water. The maximum acceptable level is 10, provided there are no E coli bacteria colonies present. For those more harmful bacteria, which are found in animal manure, there is no safe level.
