This was one of the dialogs I had with the town on this matter:

Thank you, Mr. Friday. As a consumer of public water from various municipalities over the last ~35 years, I've NEVER seen that degree of discolored water come from a municipal water supply. It does not seem plausible that this condition is uniquely from normal sediment that builds up over time -- especially if a competent program of flushing is in place. But, I feel comforted knowing you are still testing the water as a follow up. If a hydrant was opened/closed suddenly, I can understand how a velocity change could stir up sediment -- perhaps in a section of line that doesn't get the benefits of the "flushing program"? Nevertheless, we are interested in the results of your continued testing.
When I starting thinking how something that looked like pond water got into my water, I was worried that perhaps the fire department might have hooked their truck up backwards to a hydrant and pumped pond water into the hydrant or something.
That made me wonder if someone were malicious, could anyone pump anything into a hydrant and bypass whatever security is safeguarding the public water plant. (It's a rhetorical question I wonder.)
I acknowledge the staff responded quickly to investigate the issue.
I may take you up on a tour of the water facilities some day -- just out of curiosity mostly. We homeschool two young children who have an affection for the game Sim City where public water works part of the game seems to fascinate them.
