Results from the Fourth Round of Tests

On Monday, June 21st, we collected two more samples, and sent them off for analysis. Today we received the results from the lab. They appear in the table below.

Site 6 2.0 ppm 0.145 ppm n/a n/a n/a
Site 7 2.0 ppm 0.123 ppm n/a 0.093 ppm 0.065
Site 8 2.0 ppm 0.332 ppm n/a 0.088 ppm n/a
Site 9 0.0 0.015 ppm n/a n/a n/a
Site 10 0.0 n/a n/a 0.031 ppm n/a

We took only two samples this time, just to confirm the continuing decrease in concentration. Based on these results we will take samples at all 10 locations next Monday, and hope to have the State lift the next restriction (drinking lake water) later next week.

[note: we still do not recommend drinking from the lake, for a variety of other reasons]
