Frequently Asked Questions about ZIP 21005 Tap Water

What contaminants are above EPA limits in ZIP 21005?

ZIP 21005 has 6 contaminants above EPA health guidelines in the latest available data, including PFPeA at 2.8x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 21005 tap water remove PFPeA?

No. Boiling does not remove PFAS, and the compounds can actually become more concentrated as water evaporates. To reduce PFAS at home, use a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis).

Do basic pitcher filters remove PFPeA?

Most basic pitcher filters are only certified to NSF/ANSI 42 or 53, which do not cover PFAS. Look for a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis) on the spec sheet.

Who provides tap water in ZIP 21005?

Public records identify CITY OF ABERDEEN as a primary water system associated with ZIP 21005. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 21005 tap water last tested?

The most recent test date used in this report is November 2023. EnviroClarity last refreshed this page on 2026-05-05.

Where can I find the official water quality report for ZIP 21005?

Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact CITY OF ABERDEEN or visit their website for the latest official report covering ZIP 21005. The EPA also maintains a national CCR locator.
