Contamination score

Higher = more contaminated vs. other cities.

Ada draws its water from three wells into the aquifer beneath the village, and its published Consumer Confidence Report shows all tested contaminants — bacteria, nitrates, and disinfection byproducts — within EPA limits with no violations in recent years. This is a genuinely clean, well-documented small-village supply rather than an estimate.
