/ . If iow to Read the Water Quality Data Tables he tables show the contaminants we found last year or the most recent time we sampled for hat contaminant. They also show the levels of those contaminants and the Environmental Protection Agency's limits. Substance that we tested for but did n;a find are not included in the tables. We sample for some contaminants less than once a year because their levels in water are not expected to change from year to year. If we found any contaminants the last time we sampled for them, we included them in the tables with the detection date. We may have done additional monitoring for contaminants that ai< not included in the Safe Drinking Watei Act.
