Call you local water utility and see if they add chloramines to your water. 3 ppm ammonia would be the highest level I've ever heard associated with chloramines, but calling the water utility would be a good first step.
If the LFS is on the same water system, they could confirm if that is a reasonable level of ammonia given their experience.
