Common Water Problems in Southern Maryland
Southern Maryland well water — drawn from the Aquia, Patuxent, and Magothy aquifers — commonly contains a combination of these issues. Each requires a specific treatment approach:
Iron (Ferrous & Ferric)
The most common complaint in Southern Maryland. Dissolved iron causes orange staining on sinks, tubs, laundry, and fixtures. Particulate iron causes rust-colored sediment. Treatment depends on the type and concentration of iron.
Hard Water (Calcium & Magnesium)
Hard water causes scale buildup on water heaters, dishwashers, and fixtures. Most Southern Maryland well water tests between 10–25 GPG. A properly sized water softener eliminates scale.
Low pH (Acidic Water)
Acidic water (pH below 7.0) corrodes copper pipes and causes blue-green staining on fixtures. An acid neutralizer raises pH to a safe range and stops corrosion.
Sulfur / Hydrogen Sulfide
The rotten egg smell in well water. Caused by sulfur bacteria or naturally occurring hydrogen sulfide gas. Treatment depends on the source — we test before recommending.
Iron Bacteria
Microorganisms that feed on iron in the water. Signs include orange slime in toilet tanks and a musty odor. Requires shock chlorination and specific filtration — not just a standard iron filter.
Sediment & Turbidity
Sand, silt, and particulate matter that clogs fixtures and damages appliances. A sediment pre-filter protects downstream treatment components and appliances.
Water Treatment Systems We Install
Iron Filters
Oxidizing iron filters remove dissolved and particulate iron from well water. We size the filter correctly for your iron concentration and flow rate. Must be installed before the water softener.
Learn moreWater Softeners
Ion exchange water softeners remove calcium and magnesium hardness. We size the softener for your household's daily water usage and hardness level. Must be installed after the iron filter.
Learn moreAcid Neutralizers
Calcite or calcite/corosex blend neutralizers raise pH to a safe range and stop copper pipe corrosion. Must be installed before the iron filter and softener.
Learn moreUV Disinfection Systems
Ultraviolet light systems eliminate bacteria, viruses, and iron bacteria without chemicals. Installed after filtration to ensure the UV light can penetrate the water effectively.
Learn moreReverse Osmosis Systems
Point-of-use RO systems provide the highest quality drinking water — removing nitrates, arsenic, PFAS, and other contaminants that whole-house filters do not address.
Learn moreSediment Pre-Filters
Whole-house sediment filters protect downstream treatment components and appliances from sand, silt, and particulate matter. The first component in any treatment sequence.

"Absolutely blown away by the service from Deep Dive Plumbing Maryland! We had ongoing issues with our well water for years — bad smell, staining, and constant problems with pressure — and nobody ever took the time to truly figure out the root cause. Terry and the team came out, performed a full water analysis, explained everything in detail, and designed a system specifically for our home instead of just trying to sell us random equipment. You can really tell they care about doing things the right way. The install was extremely clean and professional, they walked us through how everything works, and our water has never looked or tasted better. The difference is unbelievable."

"By far, hands down, the best customer service I have experienced. The technician from Deep Dive Plumbing Maryland was incredibly helpful, professional, and patient throughout the entire process. He quickly assessed the problem, explained what was causing it, and carefully removed the cover without damaging anything. It's rare to find companies that combine technical expertise with genuinely outstanding customer service, but Deep Dive Plumbing Maryland absolutely delivered on both."

"I needed a repair on my water softener after the original installer no longer serviced my area. Deep Dive Plumbing responded quickly, diagnosed the issue, and had my system repaired the very same day. The team was professional, knowledgeable, and easy to work with. They took the time to explain what was wrong and what needed to be done to get the system operating properly again. I greatly appreciated their prompt service and commitment to solving the problem. Thank you for getting my water softener back up and running so quickly!"
