Earlier this week we sampled two locations in the lake and submitted them to the lab. The concentration of triclopyr in the lake is now about 10 parts per billion. The warning signs around the lake will have to stay up for the full 120 days, until the end of September.
The following table shows these results, as well as those for all of the other tests this summer. The concentrations are expressed in parts per billion.
