What Morristown's Water Means for Your Home
Hardness: 60 PPM - Low Concern
Morristown's water is moderately hard at 60 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. The minerals come from the local aquifer geology. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Lead levels deserve attention. At 6.7 ppb, Morristown is above the ideal of zero, though below the EPA action level of 15 ppb (dropping to 10 ppb in November 2027 under the Lead and Copper Rule Improvements). The lead typically comes from aging service lines or interior plumbing, not the treatment plant. A point-of-use filter certified for lead at the kitchen faucet is a practical safeguard, especially in older homes.

Recommendations for Morristown Homes
Quick Fix for Chlorine: Shower Filter
At 1.1 mg/L chlorine, many Morristown residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.
How to Test Your Water in Morristown
Lead enters water from your home's plumbing, not the treatment plant — so Morristown's city-wide average of 6.7 ppb may not match your tap. Testing your specific faucet is the only way to know. Run cold water for 30 seconds before collecting a sample.

About Morristown's Water Supply
Water Utility: Southeast Morris County MUA
Water Source: Clyde Potts Reservoir (Groundwater)
Population Served: 270
Hardness: 60 PPM (3.5 grains per gallon)
Morristown draws its drinking water from groundwater sources — Clyde Potts Reservoir. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 270 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Southeast Morris County MUA's Consumer Confidence Report (CCR) or test your own tap.
