Matched to what EPA's records actually show for KETCHIKAN PUBLIC UTILITIES (grade A, 90/100) — not to what sells.
EPA SDWIS/ECHO 2026Q2 · UCMR5 (2023–2026, July 2026 release) · SYR4 six-year review 2012–2019 · Full Ketchikan water quality report · Methodology
Activated carbon block (disinfection byproducts). Disinfection byproducts averaged above 80% of the EPA limit in KETCHIKAN PUBLIC UTILITIES's 2012–2019 monitoring. Carbon block filters reduce TTHM and HAA5 along with the chlorine taste that comes with them; any RO system's carbon stages do the same.
Optional but sensible. KETCHIKAN PUBLIC UTILITIES's results are below federal limits, so activated carbon block (disinfection byproducts) is a precaution rather than a necessity.
An NSF/ANSI 42 carbon pitcher or faucet filter for chlorine taste; add NSF/ANSI 53 lead reduction if your home predates 1986.
KETCHIKAN PUBLIC UTILITIES's latest Lead and Copper Rule 90th-percentile result was 2.5 ppb (2022-01-01 to 2024-12-31), below the 15 ppb action level. Lead enters from service lines and home plumbing, so test at the tap if your home is older.
No. None of the 116 UCMR5 PFAS results for KETCHIKAN PUBLIC UTILITIES (2025-02-05 to 2025-12-16) were at or above the reporting limit.
Look for: NSF/ANSI 53 with a TTHM/VOC claim, or NSF/ANSI 42 for taste
Disinfection byproducts averaged above 80% of the EPA limit in KETCHIKAN PUBLIC UTILITIES's 2012–2019 monitoring. Carbon block filters reduce TTHM and HAA5 along with the chlorine taste that comes with them; any RO system's carbon stages do the same.
| Evidence | Result | EPA limit | Period | Source |
|---|---|---|---|---|
| Haloacetic acids (HAA5) | 74.853 ug/L (average of 74 samples) | 60 ug/L | 2012–2019 | EPA SYR4 six-year review |
Look for: Certified drinking-water lab
Utility data describes water leaving KETCHIKAN PUBLIC UTILITIES. Lead, copper and some PFAS enter between the main and your faucet, so a mail-in lab test is the only way to know what your household actually drinks — and the cheapest way to avoid buying a filter you do not need.

Cost ranges are typical retail prices, not quotes. Removal marks describe the filter class when certified for that contaminant — always check the NSF/ANSI listing of the exact cartridge. Full pitcher vs under-sink vs faucet comparison →
A filter is only certified up to its rated capacity — breakthrough happens when a cartridge runs past it. Budget the cartridges, not just the unit.
| Filter | Change interval | Annual cartridge cost | Replacements |
|---|---|---|---|
| Reverse osmosis (APEC ROES-50) | typically pre-filters every 6–12 months, RO membrane every 2–3 years, post-carbon yearly | typically $50–$90 | Replacement RO filter sets → |
| Under-sink carbon block (Waterdrop TSA / 10UA) | typically every 6–12 months (rated 8,000 gal or 12 months) | typically $30–$60 | Replacement under-sink cartridges → |
| Pitcher (ZeroWater / Brita Elite) | typically every 2–6 months (ZeroWater 20–40 gal depending on TDS; Brita Elite 120 gal ≈ 6 months) | typically $60–$150 | Replacement pitcher filters → |
Amazon Subscribe & Save ships cartridges on the interval you choose at a small recurring discount, which is the easiest way to keep a certified filter within its rated life. Costs are typical retail figures, not quotes; check the capacity printed on your exact cartridge.
A point-of-use (under-sink) system typically runs $200-$600 installed; whole-house treatment $1,000-$3,000+ depending on flow and what has to come out. Tell us where you are and a certified water-treatment installer serving Ketchikan will follow up - no obligation.
