Frequently Asked Questions about ZIP 30067 Tap Water

What contaminants are above EPA limits in ZIP 30067?

ZIP 30067 has the contaminants tracked here above EPA health guidelines in the latest available data. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 30067 tap water remove the contaminants tracked here?

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 30067, a certified filter is more reliable.

Do basic pitcher filters remove the contaminants tracked here?

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 30067?

Public records identify COBB COUNTY as a primary water system associated with ZIP 30067. Service boundaries can vary by address, so confirm exact service with the utility.
