During the reactivation sampling, Toluene was detected at 1.5µg/L. This result requires
increased monitoring in accordance with R309-205-6(2)(j). The quarterly requirement can be
reduced to one sample per year once there are at least two quarters of volatile organic results, and
the results are all below respective maximum contaminant levels (MCLs).

Please contact David Kruse at (385)-566-7789 or [e-mail] for questions regarding the
source monitoring and reporting requirements for your water system.

Sincerely,

Mark Berger
Monitoring and Standards Implementation Manager
