Assistance Type:	OTHER REGULATORY - Use of emergency surface water source
Reasons:	SWTR

Details:	Timberline Lodge started using the surface water source and treatment (newly approved cartridge filters with chlorination for contact time) yesterday, April 7th, due to the horizontal well drying up. Surface water treatment parameters in range: filtered turbidity around 0.4 NTU, low pressure differential across filters, chlorine at 1.4 mg/L. System anticipates using surface source for roughly 2 weeks and will complete daily readings on monthly report for April for compliance. I decided to keep as emergency source since long term plan is to drill a new horizontal well this summer to keep up with demand as sole active source for winter high demand periods to come. No raw water E. coli monitoring for LT2 required for anticipated 2 week use of surface source.
