Certified Filters for Round Rock Tap Water
lithium was detected above EPA limits. These filters are independently certified to reduce common drinking-water contaminants.
Pitcher filter
Epic Pure XP Water Filter Pitcher
NSF-certified dual-layer filtration reduces 70+ contaminants including PFAS, lead, chlorine, microplastics, and bacteria.
NSF/ANSI 42, 53, 401 & P473Removes 99.99% PFASMade in USABPA-free
PFAS detected in 78665 · What you can do
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.
Certified PFAS filter types - how they differ
Certified Pitcher
Removes PFAS (99%+)
No installation, works today
Lowest upfront cost (~$70)
Must refill manually
Filters only what you pour in - not cooking water
Reverse Osmosis More complete
Removes PFAS + lead, arsenic, nitrates & more
Always-on - no refilling ever
Noticeably better tasting water
Filters drinking & cooking water automatically
Higher upfront cost ($200-$400)

Frequently Asked Questions about ZIP 78665 Tap Water
What contaminants are above EPA limits in ZIP 78665?
ZIP 78665 has 38 contaminants above EPA health guidelines in the latest available data, including lithium at 5.9x the EPA guideline. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 78665 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 78665?
Public records identify CITY OF ROUND ROCK as a primary water system associated with ZIP 78665. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 78665 tap water last tested?
The most recent test date used in this report is October 2025. EnviroClarity last refreshed this page on 2026-05-05.
Where can I find the official water quality report for ZIP 78665?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact CITY OF ROUND ROCK or visit their website for the latest official report covering ZIP 78665. The EPA also maintains a national CCR locator.
