• UCMR 5 testing found none of the six PFAS compounds regulated by the 2024 federal rule in Louisville's finished water - only a trace of the unregulated short-chain PFPeA at 0.003 ug/L.
• In the late 1800s the town supported roughly twenty saloons alongside plow manufacturers, breweries, tanneries and mills, giving it what local history calls a rather notorious reputation.
