HOLLY SPRINGS, TOWN OF (EPA PWSID NC0392050) delivers surface water to 51,947 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Your tap can differ from the city record
The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Choose your situation
Older buildings may have lead service lines, solder or fixtures. Lead is not in Holly Springs’ published record, so only a tap test tells you. Test first-draw water, then filter if needed.
8 of 29 PFAS tested were detected in Holly Springs’ record (PFOS 12 ng/L, PFOA 5.9 ng/L and PFHxS 3.2 ng/L, and more); 2 above their limit. If PFAS matters to you, a filter certification names each compound it covers.
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes.Is Holly Springs tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Holly Springs, PFOS 12 ng/L and PFOA 5.9 ng/L were measured in one EPA sample each, above the 4 ng/L limit EPA set in 2024 (not a violation: the limits are judged on a yearly average, due 2029). HOLLY SPRINGS, TOWN OF (PWSID NC0392050) has a Purity Score of 57/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →
Who provides tap water in Holly Springs?

Are PFAS "forever chemicals" in Holly Springs's water?
Yes. In EPA's UCMR 5 testing (2024-02-06 to 2024-11-06), PFOS was measured at 12 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024 and PFOA was measured at 5.9 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. EPA's 2024 limits are judged on a yearly average, and water systems have until 2029 to meet them, so a single sample is not a violation. PFBS (4.5 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (7.4 ng/L, below the 400,000 ng/L state limit) and PFHxS (3.2 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (7 ng/L), PFHpA (3.4 ng/L) and PFPeA (8.1 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →
Is there lead in Holly Springs's tap water?
Lead is not in Holly Springs's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours. Your household →

How PurityMap reads Holly Springs’ water
- 01Source data
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
- 02Normalize
Units converted to one basis; a non-detect kept distinct from zero.
- 03Classify
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
- 04Compare to the named reference
Every value sits against its own reference, never a blended one.
- 05Score
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
- 06Match treatment
Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. HOLLY SPRINGS, TOWN OF · PWSID NC0392050 · Purity Score 57/100 (Fair) · Confidence: moderate · Assessed at the water-system level
