Frequently Asked Questions about ZIP 70117 Tap Water

What contaminants are above EPA limits in ZIP 70117?

ZIP 70117 has 4 contaminants above EPA health guidelines in the latest available data, including lithium at 1.1x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 70117 tap water remove lithium?

No. Boiling tap water does not remove lithium. Lithium is a dissolved mineral, so heat does not break it down and evaporation can actually concentrate it. Reverse osmosis (NSF/ANSI 58) is the most reliable at-home option for reducing lithium.

Do basic pitcher filters remove lithium?

Standard pitcher filters are not certified to reduce lithium. Reverse osmosis (NSF/ANSI 58) is the most widely available home option for reducing lithium in drinking water.
