Water Quality

Aurora takes great pride in the quality of our drinking water. Our labs test over 87,000 samples system-wide to ensure that the great tasting water we deliver to your house everyday meets and exceeds all state or federal regulatory standards. Every year, we provide a technical report on the results of our continuous laboratory testing.

Beer brewers and fish tank owners often need more information about our water than
the EPA requires us to report,so we've included some of it below. Hope it's helpful.
