Raleigh's water: soft, low in lead, and drawn from two Wake County lakes
Raleigh Water supplies about 650,000 residents in Raleigh, Garner, Wake Forest, Rolesville, Knightdale, Wendell and Zebulon. Its system includes two treatment plants, 27 elevated storage tanks, about 2,600 miles of water line, around 70,000 valves and more than 26,000 hydrants.
Lake water, and why the watershed program matters
The supply comes from two reservoirs: Falls Lake in northern Wake County and Lake Benson in Garner. The state's September 2020 source water assessment rated both as highly susceptible to potential contamination sources. That rating is based on how many such sources sit in the watershed and how the land drains, and it doesn't mean contamination has been found. Raleigh's response is its watershed protection program, which so far has permanently protected more than 11,000 acres and 120 miles of streams that drain to its intakes.
Very soft water
This is the main difference from most of the big-city guides on this site. Raleigh's water is soft. The 2025 figures:
- Total hardness: average 25.2 mg/L as CaCO3 (range 21.9–35.3), or about 1.5 gpg
- Alkalinity: 29.8 mg/L
- Sodium: 24.3 mg/L
- Sulfate: 46.3 mg/L
- pH: about 8.4
In practice, soap lathers easily, you won't fight much scale in kettles or water heaters, and a softener isn't worth buying. If a salesperson's test strip says otherwise, check the units with our hardness converter. Spotting on glassware usually comes from dissolved solids, not hardness.
Lead and copper
The 2025 tap sampling covered 85 homes. None exceeded the lead action level, the 90th percentile was below detection, and the highest single result was 4 ppb. Copper's 90th percentile was 0.04 ppm (action level 1.3), again with 0 of 85 sites above.
Raleigh Water reports that it has never found a lead service line. Its Lead and Copper Rule Improvements work focuses on galvanized lines, as described in the FAQ below. You can look up your line in the city's online service line inventory and request a free lead test kit through a QR code in the report. Because lead usually comes from solder and brass fixtures in older homes, a test is the quickest way to know if a kitchen filter is worth it.
Treatment byproducts and other results
Surface water carries organic matter, and chlorine reacts with it to form byproducts. In 2025, total trihalomethanes measured 34.2 ppb (range 7.6–42.8, limit 80) and HAA5 measured 22.0 ppb (range 4.28–33.6, limit 60). Total organic carbon removal beat the requirement with a ratio of 1.48 (anything above 1.0 complies). Turbidity peaked at 0.08 NTU, and 100% of monthly samples met the limit. Fluoride was 0.71 ppm.
A look at the lab
The 2025 report profiles Raleigh Water's laboratory, which is moving into a new home. Each year the team drives about 38,083 miles collecting samples and handles about 52,664 samples. It tests for 71 parameters in drinking water and 41 in wastewater. The public can attend the utility's commission meetings on the first and third Tuesdays of each month to comment on water issues.
Raleigh water, answered
Do I need a water softener in Raleigh?
Almost certainly not. Raleigh's 2025 average total hardness was 25.2 mg/L (about 1.5 grains per gallon), with a range of 21.9–35.3. That counts as soft water. A softener would add sodium and upkeep cost for little benefit.
Does Raleigh have lead service lines?
Raleigh Water says it has never found a lead pipe in its system and, given the system's age, doesn't expect to. Crews occasionally find a lead gooseneck, the short connector between the main and the service line, but those are extremely rare. The bigger concern is lead solder and fixtures inside older homes.
Why does Raleigh care about galvanized pipes?
If a galvanized iron service line was ever downstream of a lead gooseneck, lead can build up on the inside of the galvanized pipe and be released later. To comply with the Lead and Copper Rule Improvements, Raleigh is finding galvanized lines through field checks and machine learning tools and replacing them.
Where can I find Raleigh's PFAS results?
Raleigh tests for PFAS voluntarily and posts the results and FAQs on its Perfluorinated Chemicals Data and Information page at raleighnc.gov.
