Providing clean, safe, and healthy water for Maryland families for over 47 years. Whether you are dealing with hard water, iron staining, or acidic well water, our Maryland water treatment experts provide custom solutions tailored to your local geology.
Licensed Water Treatment Professionals Serving Every County in Maryland.
Maryland’s geology varies significantly—from the hard water of the Piedmont region to the high iron levels found in Southern Maryland. Because of this, a “one size fits all” filter from a big-box store rarely works.
As a leading Maryland water treatment company, we specialize in diagnosing and treating the specific contaminants found in MD well water, including:
Hard Water: Common in Frederick and Carroll Counties.
Acidic Water (Low pH): Prevalent throughout the state, leading to blue-green staining and copper pipe corrosion.
Iron & Manganese: Causing orange or black staining on fixtures.
Bacteria & Nitrates: Requiring professional UV light or chlorination systems.
Maryland’s water quality is a direct result of its diverse landscape. Homeowners in the state generally get their water from one of two sources:
Private Wells: Most common in rural and suburban areas. These require individual treatment systems to manage minerals, acidity, and bacteria.
Municipal Water: While treated by the city, many Maryland residents still opt for supplemental filtration to remove chlorine tastes, odors, and hard water minerals.
To design an effective system, we evaluate these primary water quality factors unique to the region:
Geological Diversity: From the sand of the Coastal Plain to the bedrock of the Piedmont, geology determines your water’s mineral profile.
Agricultural Runoff: Nitrate levels are a significant factor in Maryland’s farming communities, requiring specialized removal.
Saltwater Intrusion: Proximity to the Chesapeake Bay can lead to increased sodium and chloride in coastal wells.
Natural Radionuclides: Certain deep-rock aquifers in Central MD can contain naturally occurring radon or radium.
Causes white buildup on fixtures and damages water heaters.
Leads to orange/brown or black staining and metallic tastes.
Causes blue-green staining and pinhole leaks in copper pipes.
Caused by hydrogen sulfide gas trapped in the well.
A tasteless, odorless radioactive gas common in Maryland’s deep-rock wells. When water is used for showering or laundry, radon escapes into the air, posing a significant long-term inhalation risk.
Risk of Coliform or E. coli after heavy rains or flooding.
We don’t guess when it comes to your family’s safety. We follow a proven strategy to ensure your water is treated correctly the first time:
We perform a high-level on-site test of your water source — whether you’re on a private well or city lines — to identify bacteria, hardness, pH imbalances, and heavy metals.
We walk you through your lab results in plain English. We explain how your specific water chemistry affects your pipes and your health, offering a clear roadmap for correction.
We build a non-proprietary filtration system designed specifically for the contaminants in your water. We prioritize high-efficiency, long-lasting components over “big box” store models.
Our Maryland-licensed technicians handle the full installation and provide ongoing support to keep your system performing at peak levels for decades.
National Water Service provides a diverse array of treatment technologies to solve any Maryland water challenge:
Each system is selected based on your water test results — not assumptions with years of experience.
We serve homeowners across the entire state. Click your county below for more information on water treatment conditions.
We recommend a professional water test at least once a year to monitor for bacteria and nitrates.
There is no “best” system—only the right system for your specific water test results. Check out the water treatment solutions.
Yes. UV water treatment is highly effective at neutralizing bacteria and microorganisms without chemicals.
Absolutely. Filtration and carbon-based systems are commonly used to eliminate unpleasant tastes and smells.
Yes. We offer free water testing for Howard County homeowners.
While Maryland municipal water meets federal safety standards, many homeowners in areas like Rockville or Towson choose to install Carbon Filtration or Reverse Osmosis. This is typically done to remove the taste and odor of chlorine/chloramines used during the city’s disinfection process and to address hard water minerals that can still be present in local lines.
If you see blue or teal-colored staining on your fixtures, your water is likely acidic (low pH). This “hungry” water is leaching copper from your home’s plumbing. If left untreated, this leads to pinhole leaks in your pipes. An Acid Neutralizer is the standard Maryland solution for this problem.
Yes, particularly in agricultural heavyweights like Carroll, Frederick, and the Eastern Shore. Nitrates from fertilizers can seep into the groundwater. Because nitrates are odorless and colorless, they can only be detected through professional testing. High levels are a significant health concern for infants and pregnant women.
Maryland is unique because it spans multiple geological zones. If you live in the Piedmont (Central MD), you likely have “fractured rock” wells that are mineral-heavy. If you are in the Coastal Plain (Southern MD/Eastern Shore), your water travels through sand and gravel, which often leads to higher acidity and iron levels.
When engineered correctly, a professional filtration system should have no noticeable impact on your home’s water pressure. We size every system based on your home’s peak flow rate to ensure you can run the shower, dishwasher, and laundry simultaneously without a drop in performance.
Don't settle for "okay" water. Get the clean, crisp water your family deserves from the most trusted Maryland water treatment company.
