City Water Quality Problems in Southern Maryland
Municipal water is treated — but treated doesn't mean perfect. We test your city water, identify what's in it, and install the right treatment system for your home.
Serving city water customers in Annapolis, Glen Burnie, Pasadena, Arnold, Severna Park, Edgewater, and throughout Anne Arundel and Calvert County.
"Meets EPA Standards" ≠ Perfect
Municipal water meets legal minimums — but legal minimums allow measurable levels of chloramines, DBPs, lead, and other compounds. Meeting the standard doesn't mean your water is ideal for your family.
The Risk Is Often in Your Pipes
Lead doesn't come from the utility — it leaches from lead service lines and solder in your own home's plumbing. The utility's water can test clean and still pick up lead before it reaches your tap.
Your Utility's Report Isn't Enough
Annual Consumer Confidence Reports show system-wide averages — not what's coming out of your specific tap. On-site testing tells you what's actually in your water at your address.
Official Water Quality Reports — Maryland Utilities
Every public water system in Maryland is required to publish an annual Consumer Confidence Report (CCR) — also called a water quality report. These reports show what the utility tested for and whether any contaminants exceeded EPA limits. They are a starting point, not the full picture: they reflect water leaving the treatment plant, not water at your tap after traveling through aging distribution pipes and your home's own plumbing.

Fix: Whole-house sediment filter
Hard water scale
Source: Calcium and magnesium in the water supply — not a health issue but damages appliances
Fix: Water softener
Our City Water Testing Process
A utility's annual report tells you what left the treatment plant. It does not tell you what is in your water after traveling through miles of distribution pipe and your home's own plumbing. Our on-site testing fills that gap.
On-site water test
We test at your kitchen tap — the water you actually drink. We measure chlorine/chloramines, hardness, TDS, pH, and lead (if your home was built before 1986). Results in 30 minutes.
Compare to utility report
We compare your tap results to your utility's most recent CCR. Differences between the utility's numbers and your tap numbers reveal what is happening in your distribution pipes or home plumbing.
Identify household plumbing issues
Lead, copper, and other metals in your water often come from your home's own plumbing — not the utility. We identify whether your pipes are contributing to your water quality issues.
Recommend only what you need
We recommend treatment based on your actual test results — not a generic package. Some city water homes need only a carbon filter. Others need a softener, RO, or lead reduction. We tell you exactly what your water needs.

Common Issues
City Water Problems We Solve
Every problem below is diagnosed with an on-site water test — not guesswork.
Chlorine & Chloramines
Warning Signs
- Strong chemical or bleach smell from tap water
- Unpleasant taste that makes you avoid drinking tap water
- Dry, itchy skin and hair after showering
- Eye irritation in the shower
- Fading of colored laundry over time
What Causes It
Municipal water suppliers in Maryland — including Annapolis and surrounding communities — are required by law to disinfect water with chlorine or chloramines (a chlorine-ammonia compound). Chloramines are increasingly common because they last longer in the distribution system. Both are effective disinfectants, but both affect taste, odor, and skin — and chloramines are harder to remove than plain chlorine.
How We Fix It
A whole-house carbon filtration system removes chlorine and chloramines before they reach any faucet, shower, or appliance in your home. Standard carbon filters remove chlorine easily; chloramine removal requires a catalytic carbon filter or a higher-capacity system. We test your water first to confirm which disinfectant your utility uses, then install the right system.
Call for a Water TestDisinfection Byproducts (DBPs)
Warning Signs
- Water that smells or tastes "off" even after chlorine is removed
- Concern about long-term health effects of treated water
- Older distribution system in your neighborhood
- Water that discolors slightly when heated
What Causes It
When chlorine or chloramines react with naturally occurring organic matter in source water, they form disinfection byproducts — including trihalomethanes (THMs) and haloacetic acids (HAAs). These compounds are regulated by the EPA, but they are present in virtually all chlorinated municipal water at varying levels. Long-term exposure at elevated levels has been associated with health concerns. Older distribution systems and warmer water temperatures increase DBP formation.
How We Fix It
A whole-house carbon filtration system significantly reduces DBPs. For drinking water specifically, a reverse osmosis system at the kitchen sink removes DBPs to near-zero levels. We can test your water and recommend the right combination based on your utility's water quality report and your household's needs.
Call for a Water TestLead from Old Pipes & Fixtures
Warning Signs
- Home built before 1986 with original plumbing
- Older brass fixtures or faucets
- Concern about children's health and development
- Water that sits in pipes overnight tastes metallic
- Visible corrosion on pipe connections
What Causes It
Lead does not come from the water source — it leaches into water from lead service lines, lead solder in older copper pipes, and brass fixtures manufactured before 1986. Maryland has thousands of homes with lead service lines or lead solder, particularly in older neighborhoods in Annapolis and Glen Burnie. The EPA's Lead and Copper Rule requires utilities to monitor for lead, but the risk is in your home's own plumbing — not the utility's system.
How We Fix It
A point-of-use reverse osmosis system at your kitchen sink removes lead to below detectable levels for drinking and cooking water. For whole-house protection — especially important for bathing young children — a whole-house filter with lead reduction media is the right approach. We can also test your water specifically for lead and advise on pipe replacement if needed.
Call for a Water TestHard Water (City Water)
Warning Signs
- White scale buildup on faucets, showerheads, and glass
- Soap that won't lather well
- Stiff, scratchy laundry
- Water heater and dishwasher failing early
- Dry skin and hair after showering
What Causes It
Hard water isn't just a well water problem. Municipal water in Maryland is sourced from rivers, reservoirs, and aquifers — and the hardness level varies significantly by utility and season. Annapolis area water from the Severn River watershed can range from moderately to very hard depending on the season. Hard water silently damages every water-using appliance you own.
How We Fix It
A properly sized water softener eliminates hard water damage throughout your home. We test your city water's hardness level first — because city water hardness varies by utility and season — then size the softener correctly for your household. Many city water customers are surprised how much a softener improves their water.
Call for a Water TestPFAS & Emerging Contaminants
Warning Signs
- Concern about "forever chemicals" in your water
- Utility has issued notices about PFAS levels
- Home near military base, airport, or industrial site
- Wanting the cleanest possible drinking water for your family
What Causes It
PFAS (per- and polyfluoroalkyl substances) — often called "forever chemicals" — have been detected in water supplies across Maryland, including communities near military installations and industrial sites. The EPA established new maximum contaminant levels for several PFAS compounds in 2024. While utilities are working to comply, many homeowners want additional protection at the point of use. PFAS are not removed by standard carbon filters.
How We Fix It
A reverse osmosis system at the kitchen sink is the most effective point-of-use treatment for PFAS, removing the majority of PFAS compounds to near-zero levels. Activated carbon block filters also provide meaningful reduction. We can advise on the right system based on your utility's water quality report and your specific concerns.
Call for a Water TestSediment & Particulates
Warning Signs
- Visible particles or cloudiness in water
- Grit or sand in water
- Clogged aerators and showerheads
- Discolored water after main breaks or pressure changes
- Appliances clogging or failing
What Causes It
City water can carry sediment from aging distribution pipes, main breaks, and pressure fluctuations. Older cast iron or galvanized steel mains in established neighborhoods shed rust and scale particles into the water. After a main break or pressure change, sediment that has settled in pipes gets stirred up and flows into homes. This is common in older Annapolis neighborhoods and parts of Glen Burnie.
How We Fix It
A whole-house sediment pre-filter installed at your main water entry point catches particles before they reach your fixtures, appliances, and water heater. We size the filter to your flow rate and install it with easy cartridge replacement access.
Call for a Water TestTaste & Odor Issues
Warning Signs
- Water that tastes flat, metallic, or chemical
- Musty or earthy smell from tap water
- Smell that varies by season
- You buy bottled water because tap water tastes bad
- Coffee and tea taste off even with filtered water
What Causes It
City water taste and odor issues have multiple causes: chlorine and chloramines (most common), geosmin and MIB from algae blooms in source water reservoirs (seasonal earthy/musty smell), hydrogen sulfide in distribution lines, and DBPs. Seasonal variation is normal — utilities adjust treatment levels throughout the year, which changes taste and odor. Annapolis area water from the Severn River watershed is particularly prone to seasonal taste changes.
How We Fix It
A whole-house carbon filter eliminates most taste and odor issues. For the best-tasting drinking water, a reverse osmosis system at the kitchen sink removes virtually everything that affects taste. We identify the specific cause of your taste or odor issue before recommending a solution.

City Water Treatment Systems We Install
Every system we recommend is based on your actual water test results — not a one-size-fits-all approach.
Whole-House Carbon Filtration
Removes chlorine, chloramines, DBPs, and taste/odor compounds from every faucet, shower, and appliance in your home. Catalytic carbon required for chloramine removal — we confirm which your utility uses before recommending.
Learn moreReverse Osmosis (Drinking Water)
Under-sink RO systems remove up to 99% of dissolved contaminants — lead, PFAS, nitrates, DBPs, TDS — for the cleanest possible drinking and cooking water. Paired with a dedicated faucet at your kitchen sink.
Learn moreWater Softeners
City water can be just as hard as well water. A properly sized softener eliminates scale buildup, extends appliance life, and improves skin and hair. We test your city water hardness before sizing.
Learn moreSediment Pre-Filters
Whole-house sediment filters catch rust, scale, and particulates from aging distribution pipes before they reach your fixtures and appliances. Essential for older neighborhoods with aging infrastructure.
Learn moreUV Disinfection
For city water customers who want an additional layer of protection against bacteria and viruses — especially after main breaks or boil water advisories — UV disinfection provides chemical-free protection.

We test your city water for chlorine/chloramines, hardness, TDS, lead, pH, and more — on-site, same visit. You get real numbers and plain-language explanations, not a sales pitch.
Learn moreWhy Test City Water?
Your utility tests the water leaving their treatment plant — not the water coming out of your tap. Between the plant and your faucet, water travels through miles of aging pipes, your home's service line, and your own plumbing. A lot can change along the way. On-site testing tells you what's actually in your water at your address.
Know What's in Your Water
Your utility's annual report shows system-wide averages. On-site testing shows what's coming out of your specific tap — including lead from your own pipes.
Protect Your Family
Lead, PFAS, and DBPs are invisible and odorless. The only way to know if they're present at your tap is to test. We test on-site, same visit.
Make Informed Decisions
We give you real data and honest recommendations. If your water is fine, we'll tell you. If it needs treatment, we'll explain exactly why and what it costs.
On Well Water?
Well Water Has Different Challenges
Iron staining, sulfur smell, low pH, hard water, and manganese are the dominant issues in Calvert and Anne Arundel County well water. The treatment approach is completely different from city water — and we specialize in both.
