What Glen Burnie's Water Means for Your Home
Hardness: 80 PPM - Low Concern
Glen Burnie's water is moderately hard at 80 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. 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. Glen Burnie's water has TTHMs at 53.3 ppb and HAA5 at 31.6 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?

What's in the Treatment Process
Glen Burnie's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 53.3 ppb (67% of the legal limit, but 355x the EWG guideline) and HAA5 at 31.6 ppb (53% of the legal limit, but 316x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

About Glen Burnie's Water Supply
Water Utility: Baltimore County Water
Water Source: Gunpowder Watershed (Surface Water)
Population Served: 1,600,000
Hardness: 80 PPM (4.7 grains per gallon)
Glen Burnie's drinking water comes from surface sources — Gunpowder Watershed. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 1.6 million residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Baltimore County Water's Consumer Confidence Report (CCR) or test your own tap.
