We have received the test results from the lower well taken 5/17/21 (just before we switched over to this well). Results came back at 4.6 which is well below the MCL of 10.
This is good news.
Thus, it can be assumed that Tooley Water District never supplied water with nitrates above 4.6 ppm during the entire time we were running on the lower well.
Moving forward we plan to keep this well off until we can better understand the fluctuations, but it is nice to know we currently have a clean backup water source.
