Miami Co-n25a Extension

• Troy's ten production wells sit under a public golf course (Miami Shores) and a city park, tapping the glacial-outwash sand and gravel buried along the ancient course of the Great Miami River.
• Troy does not fluoridate its water - twice, by referendum, residents voted against it. The 0.38 ppm of fluoride in the tap is what nature put in the aquifer and treatment left behind.
• Water rates in Troy have not changed since January 1, 2017, even as the city raised sewer rates for 2026.
• The plant has treatment capacity for 16 million gallons a day but averaged 3.66 million in 2025 and peaked at 5.62 million - roughly a third of what it could produce.
• Troy's own utility fee schedule contains an order-of-magnitude typo, describing 1,000 cubic feet of sewage as 'approximately 75,000 gallons.' It is about 7,480.

Troy's own water quality report states that the wellfield sits above a buried valley aquifer providing 'limited natural protection from contaminations infiltrating into the aquifer,' and that the aquifer supplying Troy is therefore 'considered to be highly susceptible to contamination.' The city runs a comprehensive wellhead protection…
