Understanding Acidic Water & Why It Matters
What makes water acidic?
Water with a pH under 7 is acidic, particularly when below 6.5, and is corrosive—this means it can erode plumbing systems, leach metals like copper and lead, and stain fixtures with green or blue discoloration National Water Service.
Symptoms you might notice include:
- Metallic or sour taste.
- Blue-green stains in sinks, bathtubs, or toilets.
- Pinhole leaks in pipes or continuous fixture corrosion
Why it’s a serious issue:
Acidic water doesn’t just damage your home infrastructure—it can pose health risks by leaching harmful metals such as lead and copper into drinking water
Why Maryland Water Is Often Acidic
In Maryland, acidic groundwater is a common issue due to the region’s unique geology. Much of the state—especially central Maryland, including the Piedmont Plateau—sits on granite and metamorphic rock formations that lack natural buffering minerals like limestone.
Because there’s little to neutralize naturally occurring carbon dioxide in rainwater and groundwater, the water remains slightly acidic as it seeps through soil and bedrock. Over time, this results in widespread low-pH water that affects private wells and even some small community systems.
In short:
- No natural buffering minerals → less protection against acidity.
- High carbon dioxide levels in groundwater → lower pH.
- Widespread well use in Maryland → more homeowners directly exposed to acidic water conditions.
That’s why so many homeowners across Maryland experience pinhole leaks, green/blue staining, or premature plumbing failures—and why acid neutralizers and chemical feeders are common solutions in the area.
Two Key Solutions: Acid Neutralizers & Solution (Chemical) Feeders
- Acid Neutralizers: Natural, Safe, and Reliable
These systems raise water pH using calcite (crushed marble) or similar minerals. As water travels through the tank, the media dissolves and gradually increases pH to a safer, neutral level.
- Why use them? They protect plumbing from corrosion and reduce metal leaching.
- Common types:
- Upflow / non-backwashing systems—simple design, no backwash required; better suited for low-sediment or softened water..
- Back-washing neutralizers—clean the media automatically and maintain even calcite distribution for consistent pH control.
These systems help prevent corrosion, extend the life of appliances and pipes, and can be paired with water softeners to manage the added hardness from calcite treatment,.
- Solution (Chemical) Feeders: Precision Treatment, Flexible Control
Also known as chemical feeders, these systems automatically inject measured amounts of treatment chemicals—such as soda ash or sodium hydroxide—into your water to precisely adjust pH, disinfect, or treat other issues like hydrogen sulfide or bacteria
- Key advantages:
- Highly accurate dosing helps maintain stable water quality.
- Versatile enough to handle multiple concerns—low pH, iron, manganese, bacteria, even odors National Water Service+1.
- Cost-effective, easily integrated, and space-saving—ideal for complex or commercial systems National Water Service+1.
Choosing the Right System for Your Situation
Acid Neutralizer is ideal when:
- You need a straightforward, chemical-free, and low-maintenance solution.
- You’re dealing primarily with low pH and corrosion issues.
- You prefer a more “hands-off” system that uses natural media.
Solution Feeder is ideal when:
- You demand precise control over pH or require treatment for multiple issues simultaneously.
- You need flexibility to add disinfectants or address odor-producing compounds like hydrogen sulfide.
- You’re managing a larger-scale, high-demand, or evolving water quality scenario.
Both systems often work best within a comprehensive treatment plan—professionally designed and periodically maintained for long-term reliability.
