Water Quality Reports

We take water quality very seriously. When it comes to complying with strict federal regulations for delivering clean, quality drinking water, we’ve consistently scored among the highest of all water companies. Currently, we score greater than 99% in drinking water compliance – a fact that we are immensely proud of.

In the past several years, and all over the country, we’ve received more than 150 awards for superior water quality from state regulators, industry organizations, individual communities, and governmental and environmental agencies. Visit our Accolades section to view some of our recent awards.
