Assistance Type:	WATER QUALITY ALERT RESPONSE
Reasons:	Disinfection Byproducts

Details:	Reached out to Jonathan Woody to discuss the high result for TTHM disinfection byproducts (TTHM = 0.1170 mg/L). USFS Tiller Ranger Station is working on operational changes to lower the TTHM levels in the water. They have started flushing monthly, reduced the reservoir levels and reduced the chlorine dosage. The HAA5 levels have been reducing, but there is still problems with the TTHM levels. The system is going to clean the tanks, install and auto-flush system, and move to post-chlorination instead of pre-chlorination.
