Frequently Asked Questions about ZIP 00901 Tap Water

What contaminants are above EPA limits in ZIP 00901?

ZIP 00901 has 6 contaminants above EPA health guidelines in the latest available data, including 6:2 FTS at 9.8x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 00901 tap water remove 6:2 FTS?

Boiling tap water can kill many pathogens, but it does not remove most chemical contaminants tracked in EPA monitoring. Several dissolved contaminants can even concentrate as water evaporates. For the chemical contaminants reported in ZIP 00901, a certified filter is more reliable.

Do basic pitcher filters remove 6:2 FTS?

Basic pitcher filters are typically rated for chlorine, taste, and odor (NSF/ANSI 42), not for the broader list of contaminants tracked in EPA monitoring. Match the certification (NSF/ANSI 42, 53, 58, or P473) to the specific compounds listed in this report before assuming a filter helps.

Who provides tap water in ZIP 00901?

Public records identify METROPOLITANO as a primary water system associated with ZIP 00901. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 00901 tap water last tested?

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

Where can I find the official water quality report for ZIP 00901?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact METROPOLITANO or visit their website for the latest official report covering ZIP 00901. The EPA also maintains a national CCR locator.
