What Hoboken's Water Means for Your Home
Hoboken's water is moderately hard at 61 PPM. At this level, hard water is not a significant concern for most households. Scale buildup is minimal, and a water softener would provide little measurable benefit. If you are considering water treatment in Hoboken, focus on contaminant filtration rather than softening.
PFAS contamination is a significant concern in Hoboken. At 6 parts per trillion, levels exceed the EPA's 2024 maximum contaminant level of 4 ppt. PFAS are synthetic chemicals that do not break down in the environment or the human body, which is why they are called "forever chemicals." Long-term exposure has been associated with increased cancer risk, thyroid disruption, and immune system effects. A whole-house activated carbon filter or point-of-use reverse osmosis system can reduce PFAS to safe levels. Look for NSF P473 certification when comparing products.

Recommendations for Hoboken Homes
🔄Salt-Free Conditioner (Optional)
At 61 PPM, Hoboken's water is moderately hard. Scale buildup is slow but noticeable over years, especially in tankless water heaters. A salt-free conditioner is a low-maintenance option if you want to extend appliance life.
PFAS detected at 6 ppt, above the EPA maximum contaminant level of 4 ppt. PFAS are linked to cancer, thyroid disease, and immune system effects with long-term exposure. A whole-house granular activated carbon (GAC) filter or a point-of-use reverse osmosis system can reduce PFAS. Look for NSF P473 certification, which specifically tests for PFAS removal.
Lead detected at 6 ppb. There is no safe level of lead in drinking water, and children are especially vulnerable. Lead typically enters water from old plumbing, not the source water. A point-of-use filter certified to NSF/ANSI Standard 53 for lead is the most practical solution. If your home was built before 1986, testing is strongly recommended.
Water quality can vary by neighborhood and season. The values above represent typical averages reported by Suez Water NJ. To get exact numbers for your address, request a copy of the most recent Consumer Confidence Report (CCR) from your utility, or have your water independently tested.
Hoboken's water meets EPA legal standards for drinking water safety. However, legal limits and health-optimal levels are different things. PFAS levels exceed the 2024 EPA health standard, which is a concern for long-term exposure. Lead levels are elevated. This is especially concerning in older buildings with lead service lines or lead solder. Review the contaminant table above for specific numbers and how they compare to both legal limits and health guidelines.
Do I need a water softener in Hoboken?
At 61 PPM, Hoboken's water is moderately hard. Some homeowners at this level do not notice problems, while others see spotting on glassware, film on shower doors, or reduced soap lathering. Homes with tankless water heaters at this hardness level should strongly consider at least a salt-free conditioner, as scale buildup inside the heat exchanger can void the warranty. For other homes, it depends on your sensitivity and fixtures.
What water filter is best for Hoboken?
The best filter depends on which contaminants you want to address. For PFAS, look for a filter with NSF P473 certification. Granular activated carbon (GAC) and reverse osmosis systems are both effective. Standard carbon pitcher filters may not remove PFAS adequately. For lead, look for NSF/ANSI Standard 53 certification specifically for lead reduction. Point-of-use filters at the kitchen faucet are the most practical approach. See our softener vs. filter guide to understand the difference between these categories.
Where does Hoboken's water come from?
Hoboken's drinking water is sourced from Passaic River, Hackensack River and treated by Suez Water NJ. Hoboken receives treated surface water from northern NJ reservoirs. Water is soft but building plumbing age varies widely.
What is the hardness of Hoboken water in grains per gallon?
Hoboken's water hardness is 3.6 grains per gallon (GPG), which equals 61 parts per million (PPM). This is classified as moderately hard. To convert: 1 GPG = 17.1 PPM.
Does Hoboken water damage tankless water heaters?
At 3.6 GPG, Hoboken's water is unlikely to cause significant issues for tankless water heaters. However, if you notice reduced flow or efficiency over time, scale buildup could be a factor. Annual flushing with vinegar is good maintenance regardless of hardness.
Is Hoboken water safe for babies and infants?
Lead is the primary concern for infants and young children. Hoboken's lead level of 6 ppb is elevated. Run the cold water tap for 30 seconds before using it for formula or cooking, and consider a certified lead-reduction filter for the kitchen faucet.
