Frequently Asked Questions about ZIP 50139 Tap Water

What contaminants are above EPA limits in ZIP 50139?

ZIP 50139 has 3 contaminants above EPA health guidelines in the latest available data, including lithium at 12.0x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 50139 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.

Who provides tap water in ZIP 50139?

Public records identify MARION CO. RURAL WATER DISTRICT as a primary water system associated with ZIP 50139. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 50139 tap water last tested?

The most recent test date used in this report is September 2024. EnviroClarity last refreshed this page on 2026-05-05.

Where can I find the official water quality report for ZIP 50139?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact MARION CO. RURAL WATER DISTRICT or visit their website for the latest official report covering ZIP 50139. The EPA also maintains a national CCR locator.
