TL;DR
Iron bacteria are microorganisms that oxidize dissolved iron and manganese in well water to fuel their metabolism, building rust-colored slime that coats pump intakes, clogs screens and pressure tanks, and stains fixtures while giving water a swampy odor. They are a nuisance rather than a pathogen, but their biofilm shelters other organisms and steadily chokes well yield.
What it means
Iron bacteria are microorganisms that oxidize dissolved iron and manganese in well water to fuel their metabolism, building rust-colored slime that coats pump intakes, clogs screens and pressure tanks, and stains fixtures while giving water a swampy odor. They are a nuisance rather than a pathogen, but their biofilm shelters other organisms and steadily chokes well yield. Confirmed by slime in the toilet tank or lab culture, they are managed rather than cured, through shock chlorination, acid-and-agitation well cleaning, and repeat maintenance.
