• The village's North production well is drilled inside the JSW Steel mill complex, and the South well sits just west of the marina, so Mingo Junction's drinking water comes out of the ground under an active steel plant…
• Until 2003 the village drew on a Ranney collector well that Ohio EPA classified as a surface-water intake; it was deactivated on March 5, 2003, and the system has been all drilled wells since.
• Population has tracked a single mill: 371 in 1880, 5,030 at the 1930 peak, 3,347 in 2020.
• Mingo Junction keeps a decade of water quality reports, 2016 through 2025, in a public Google Drive folder linked off its water department page, which is more than many villages its size publish.
