Frequently Asked Questions about ZIP 97741 Tap Water

What contaminants are above EPA limits in ZIP 97741?

ZIP 97741 has lithium above EPA health guidelines in the latest available data at 1.1x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 97741 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 97741?

Public records identify MADRAS, CITY OF as a primary water system associated with ZIP 97741. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 97741 tap water last tested?

The most recent test date used in this report is May 2025. EnviroClarity last refreshed this page on 2026-05-04.

Where can I find the official water quality report for ZIP 97741?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact MADRAS, CITY OF or visit their website for the latest official report covering ZIP 97741. The EPA also maintains a national CCR locator.
