What Montgomery's Water Means for Your Home

Montgomery's water is slightly hard at 41 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 Montgomery, focus on contaminant filtration rather than softening.

PFAS contamination is a significant concern in Montgomery. At 7 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 Montgomery Homes

🔬 Activated Carbon Filter for PFAS
PFAS detected at 7 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.

Frequently Asked Questions About Montgomery Water

Is Montgomery tap water safe to drink?
Montgomery'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. 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 Montgomery?
Probably not. At 41 PPM, Montgomery's water is on the softer end. Most homes will not experience noticeable scale buildup. That said, if you have high-end fixtures, a glass shower enclosure, or a tankless water heater, even mild hardness can leave mineral deposits over time. A salt-free conditioner is a low-cost insurance policy in that case.
What water filter is best for Montgomery?
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. See our softener vs. filter guide to understand the difference between these categories.
Where does Montgomery's water come from?
Montgomery's drinking water is sourced from Tallapoosa River and treated by Montgomery Water Works. Montgomery's water is slightly hard at 41 PPM, typical of the Southeast Piedmont region. The water quality is generally good, and most homes don't need a water softener at this hardness level.
What is the hardness of Montgomery water in grains per gallon?
Montgomery's water hardness is 2.4 grains per gallon (GPG), which equals 41 parts per million (PPM). This is classified as slightly hard. To convert: 1 GPG = 17.1 PPM.
Does Montgomery water damage tankless water heaters?
At 2.4 GPG, Montgomery'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 Montgomery water safe for babies and infants?
Montgomery's water meets all EPA safety standards and is generally considered safe for preparing infant formula. The hardness minerals (calcium and magnesium) are not harmful. If your home has older plumbing, running cold water for 30 seconds before use is a good precaution to flush any lead from pipes.
