Frequently Asked Questions about ZIP 70765 Tap Water

What contaminants are above EPA limits in ZIP 70765?

ZIP 70765 has 4 contaminants above EPA health guidelines in the latest available data, including lithium at 2.1x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 70765 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 70765?

Public records identify CITY OF PLAQUEMINE WATER SYSTEM as a primary water system associated with ZIP 70765. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 70765 tap water last tested?

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

Where can I find the official water quality report for ZIP 70765?
