A failed El Paso County well bacteria test needs follow-up

A private well in El Paso County sits outside the usual rulebook: no specific regulation or law sets the water-quality standard for it. Public Health fills that gap by judging private wells against the same standards used for public drinking water, so the bar your kitchen tap has to clear is the same one a town system clears.

Under those standards, a sample fails the moment coliform bacteria show up. Coliform is a family of bacteria common in soil and surface water, and finding it in well water is the warning sign that something unwanted is getting in. The encouraging part is that a failure is often fixable. Chlorinating the well frequently corrects the conditions behind a bad sample, and a follow-up test confirms whether it worked.

A failed bacteria result, then, is not a vague worry to file away. It is a clear instruction to stop guessing and check back with Public Health, a qualified water professional, or a certified lab. Clear, good-tasting water at the faucet proves nothing about what the bacteria count actually is.

Before closing on a well-served home, renting one, or moving back into one that sat empty, read the actual lab result rather than the listing language. If coliform appears, the question to ask is what correction and retesting come next, before anyone counts on that water for drinking.
