• One of the city's supply wells sits on the far side of the Kokosing River, behind the water plant's own sludge lagoons.
• The aquifer under Mount Vernon's well field is so shallow — under 15 feet to water, with as little as zero feet of protective clay — that state assessors rate it highly susceptible to surface contamination.
• Mount Vernon disinfects with chlorine dioxide, unusual for a small groundwater system; the giveaway is chlorite showing up in its annual report as a by-product.
• The city's stormwater fee is measured in 'Equivalent Residential Units' of 2,900 square feet — before the utility existed, stormwater work was quietly eating about 40% of the Street Department's budget.
• The city's own rate FAQ benchmarks its sewer bill against Danville, Fredericktown and Centerburg — and Mount Vernon came out cheapest by a wide margin, $19.60 a month against Centerburg's $83.19 for the same 3,000…
