AIKEN CITY OF (SC0210001) (EPA PWSID SC0210001) delivers surface water to 51,533 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.
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score. All 7 EPA filings are listed below.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 2.7 µg/L, below the 15 µg/L action level (detected below the limit); 1 galvanized line to replace (context, not a tap measurement)
PFHxS 3.2 ng/L, below the 10 ng/L limit (+1 more PFAS detected)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Aiken, PFAS were detected below their limits; the lead 90th-percentile result was 2.7 µg/L against the 15 µg/L action level. AIKEN CITY OF (SC0210001) (PWSID SC0210001) has a Purity Score of 89/100 (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.
AIKEN CITY OF (SC0210001) (PWS ID SC0210001) is the public water system on record for Aiken, South Carolina, serving about 51,533 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2025-03-18 to 2026-04-20), PFBS was detected at 3.1 ng/L, below the 2,000 ng/L EPA health advisory and PFHxS was detected at 3.2 ng/L, below the 10 ng/L federal limit.
AIKEN CITY OF (SC0210001)'s most recent lead 90th-percentile result (2024–2026) was 2.7 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
PurityMap's current record for Aiken holds 31 findings: 3 detected within the reference and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
