What Bel Air's Water Means for Your Home
Hardness: 90 PPM - Low Concern
Bel Air's water is moderately hard at 90 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
Disinfection byproducts are the notable finding here. Bel Air's water has TTHMs at 4.8 ppb and HAA5 at 0.367 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture?

About Bel Air's Water Supply
Water Utility: City of Bel Air Water
Water Source: Deer Creek Reservoir (Groundwater)
Population Served: 5,447
Hardness: 90 PPM (5.3 grains per gallon)
Bel Air draws its drinking water from groundwater sources — Deer Creek 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 5,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Bel Air Water's Consumer Confidence Report (CCR) or test your own tap.
