Water Quality: Chemical Testing: Seasonal Influences and Toluene Levels in the St. Clair River
Water Monitoring Results - 2007
In over 99% of the analyses, the target compounds were either not present, or were below measurable levels. 12 of the target compounds remained below their measurable limits for the entire year. Those measured above detection limits at least once during the year are listed in the table below.
Toluene continues to be detected most frequently; the results follow an established pattern of higher levels during summer weekends when recreational boating is greatest.
