Frequently Asked Questions About Middletown Tap Water
Middletown's water has 1 contaminant above EPA MCLGs and 1 above EPA's legal limit (MCL). We recommend using a certified water filter for additional protection, especially for vulnerable populations like children, pregnant women, and those with compromised immune systems.
