Typically the DOH would require these samples to be drawn from homes in the service area. However, Yodelin has received a variance from this that allows us to sample at the [[locations:pumphouse]] since to sample at home in the winter, the water operator would have to travel through avalanche terrain and also have unattended access to residents homes. ===== Annual Testing ===== We must submit water samples annually for nitrates. This is done by the water operator with samples from the [[locations:pumphouse]] operations/testing.txt Last modified: 2026/06/28 00:26by zeagle
