Are you interested or do you think you need water treatment for your home or place of business? Here are a few reasons why you should use National Water Service for all of your water treatment and well pump needs.

  • Free Consultation:  Before we install any water treatment system, a water test is needed.  As such, one of our experienced technicians will come to your home or office for a free consultation. After the water is tested, we discuss our findings and what you like and don’t like about your water. Most importantly, we determine what you are looking for in a water treatment system. Only after the consultation will we make recommendations as to what water treatment system best suits your wants and needs.
  • Safer, Cleaner Water: Undoubtedly, the top benefit of installing a water treatment system is that you will have safer, cleaner water. Clean water will benefit the health of you and your family members. All  water treatment system, we install are customized to each individual customers wants and needs.  Water Purification systems can remove impurities such as sediment, chlorine, radon, bacteria and other containment from your water. In addition to being cleaner and safer, your water will also smell and taste better. As a result, you will no longer spend money on plastic water bottles that end up in our landfills.
  • Eliminate Your Water Issues: The primary reason to install a water treatment system is to remove dirt, sediment, radon, bacteria and any of the other 18 million contaminants that can be in your water.  At National Water, we don’t just address the contaminants in your water, but any other issues you may be having with your water such as pH and hardness. Addressing the issue of hard or soft water or low or high pH with a water treatment system will prevent corrosion in your pipes as well as spotting on your dishes and staining on your appliances. In addition, we offer flood prevention, storage tanks for low yielding wells, constant pressure systems and much more to allow you to be in complete control of your water.
  • Low Maintenance with Annual Service: A quality water treatment system can last decades and should require little to no maintenance to the homeowner. We do however recommend, to prolong the life and efficiency of your system, to have annual maintenance completed by a certified water treatment specialist.

Last week National Water had the privileged of hosting the HocoBots, a group of talented 5th-8th graders from Howard County, Maryland. The HocoBots are a seven-member FLL team based out of Howard County and study in FQMS, MVMS, and MWES. Some of its members have been part of FLL for almost four years. The HocoBot members have won several Championship awards at the qualifiers over the years. HocoBots is proud to say that some of its team members have represented Howard County at State level competition 3 times so far and will be representing Howard County again this year on Feb 24th at UMBC.

The HocoBots are a member of the FLL (First Lego League)  which is a part of FIRST (For Inspiration and Recognition of Science and Technology) engaging young kids in an exciting Mentor-based program that build science, engineering, and technology skills, that inspire innovation, and that foster well-rounded life capabilities including self-confidence, communication, leadership and contributors to the society.

Guided by two or more adult Coaches, FIRST LEGO League* teams (up to 10 members, grades 4-8**) research a real-world problem such as food safety, recycling, energy, etc., and are challenged to develop a solution. They also must design, build, program a robot using LEGO MINDSTORMS®, then compete on a table-top playing field. Along their journey, they develop critical thinking and team-building skills, basic STEM (Science, Technology, Engineering, and Math) applications, and even presentation skills, as they must present their solutions with a dash of creativity to judges. They also practice the Program’s Core Values, which emphasize discovery, teamwork and good sportsmanship.

This years challenge relates to hydrodynamics or how humans find, use, transport and dispose of water. The HocoBots created a product that can sense the purity of  your water and instantly notifies you if your water has become impure via a text message. These young student are a true inspiration and we had a wonderful afternoon discussing their invention and showing them some of the water treatment and filtration systems we use. We look forward to working with the Hocobots in the future and wish them all the best at their upcoming competition. 

If you are on city water, you pay a quarterly bill for water to be collected, treated, and pumped to your house.   Your municipality installed the 50 million dollar treatment system and its users (you) are paying for its cost and upkeep.  In addition, city water is notorious for harboring a host of tasteless and odorless contaminants.   There are boil water alerts here and there, dead bodies of animals found in municipal ponds, pharmaceuticals and illegal drug traces, and that’s just the tip of the iceberg.   Despite what is commonly said about the safety of city water, the daily news stories across the land paints a far different picture. Reverse Osmosis, Carbon Tanks, and Water Softeners should be considered to clean up city water.  And if you are in the market for a water system, stay away from internet products, hardware stores, franchises, and other proprietary products.   These types of systems usually save you a couple of dollars on the front end, but cost you far more down the road.  And from franchises like Culligan, RainSoft, Hague, EcoWater and many others, they cost thousands more than they should and the maintenance is equally egregious.   A good water system should be non-proprietary and last 30 years with proper maintenance.  The cost of service on a basic water system should average around $200 per year.

If you are on a well, Congratulations!   Your well is likely free of man-made contamination!   You are also not going to get a quarterly bill.   Free Water! (kinda)   So on the flip side, almost all wells need some sort of water treatment.   If you drill a hole in the earth, you are likely to get some of the earth’s elements in your water!   Sediment, Acid Water, Iron, Manganese, Hard Water, and Radon are just a few of the common ailments of well water.  Aside from Radon, most of the contaminants found in wells are nuisances and are not harmful to health.   The average well owner should spend about $4000.00 on a quality whole house water treatment system and that system, assuming it doesn’t come from the internet, Home Depot, or a Franchise, should last 30+ years with proper annual maintenance.  Once again, in some towns, franchises like the ones mentioned above will charge $8000.00+ because they are the closest water company in the community.   There is a lot of gouging from franchises so beware!  On top of that, since a Franchise sells you a proprietary product, you marry yourself to that company and any fees along the way.  Some of these franchises redesign their equipment on a regular basis to build in obsolescence.  The common rule is…. You buy from a franchise one time and you’ve learned your lesson.

One final thought…. THERE IS NO $10.00 FILTER THAT WILL SOLVE YOUR WATER PROBLEMS!  Home Depot, Lowes, etc cannot help you with a permanent solution.  Water is different from state to state, county to county, city to city and well to well!   The Water Treatment Companies in your state, county or city know your water the best.

Reverse Osmosis, or RO, by definition, is a technology that is used to remove a large majority of contaminants from water. RO’s remove impurities by pushing pressurized water through a semi-permeable membrane. A Reverse Osmosis water treatment system is capable of removing up to 99% of all contaminants from water. Contaminants include, but are not limited to, pharmaceuticals, dissolved salts (ions), organic particles and bacteria, including e-coli.

An RO works by forcing water through different pre-filters, including sediment and carbon in order to remove all impurities.  Finally, the water passes through the membrane and finally to your faucet. The first filter is for sediment, to trap particles, including dissolved solids such as calcium carbonate.  The second filter, also for sediment, has smaller pores to catch the finest of sediment.  The third filter, an activated carbon filter, to trap organic chemicals and chlorine as well as control odor.  Finally, the water passes through the thin film composite membrane. Once the water passes through the pre-filters and membrane, it is ready to use. Water from an RO’s is so pure it needs its own waterline and faucet, that prevent corrosion. RO water is the freshest, cleanest drinking and cooking water available today.

RO technology has many different uses. The most common is to desalinate ocean water into potable water for drinking and cooking. Commercial sized RO systems are commonly found on ships or in arid countries. RO’s are also used in the production of concentrated juices, as well as on all produce misting bars in Whole Foods.

An in home RO can be installed under the sink for single use, such as a faucet in the kitchen and a line to an ice maker or refrigerator.  In addition, larger RO’s are installed in basements or water treatment areas. Larger RO’s can accommodate many water lines, including multiple faucets, refrigerators or ice makers. The price of an RO fully installed is roughly the same price the average family of 4 spends on bottled water annually. Clean water and preventing more plastic bottles from entering our landfills is the perfect way to stay Green in 2019. In home RO systems provides endless safe, healthy, clean cooking and drinking water. 

Radon is a naturally occurring radioactive gas and comes from the natural breakdown or radioactive decay of uranium. It is usually found in igneous rock and soil, however well water may also be a source of radon. Radon is measured in Pico Curies per Liter (pCi/L). The EPA recommends that homes with Radon levels of 4 pCi/L in the air have remediation installed in the home. 10,000 pCi/L of radon in water adds 1 pCi/L to radon in the air. Levels below 4 pCi/L of radon in the air still pose a significant health risk according to the EPA,  Centers for Disease Control, the American Lung Association and the American Medical Association.

Radon is the leading natural cause of lung cancer in the US and the sixth leading cause of all types of cancers. Currently, the EPA only requires testing of radon in the air, but they have recently decided to re-evaluate that positions due to the widespread findings of radon in water. Montgomery County was one of the first counties in the country last year to require radon tests for the sale of a home and while the test alludes to radon in air testing, it does not specifically state air or water.

In the past year alone, we have found very high levels (up to 60,000 pCi/L) of radon in wells all around the entire Washington, DC Metro Area, specifically in Montgomery and Howard Counties in Maryland & Loudoun County in Virginia. Each and every week, we have been installing radon remediation water treatment equipment in homes and offices throughout the entire area. There are many different types of radon remediation available to you depending on the level of radon present. For those with high levels of radon in water , an AIRaider can successfully and dependably remove radon and other Volatile Organic Compounds (VOCs) from your well water through a multi-stage aeration method that provides up to 99%+ radon reduction. For lower levels of Radon in water, a carbon tank will remove Radon from water to a safe level.

Please have your water tested today, it may save a life! Call us today at 301-854-1333 to schedule a test!


The most common question we receive from new customers is “What water treatment systems do I have and what are their functions?”
Every well and every homeowners water wants and needs are different. One of our main objectives is to only install the equipment that our customers need to ensure that they have clean, safe potable water.
We have found that the majority of new home owners are not familiar with the equipment that makes up their water treatment system. We strive to educate all of our customers so they know exactly what type of treatment they have and its function.
Each new customer, be it a new installation, or someone who purchases a home with water treatment that we service, receives a picture, like the ones above and below,  to help them identify what exactly they have treating their water!


For over 40 years, National Water Service has been a Leader throughout the Mid-Atlantic Region for all things Water Treatment, Water Testing, and Well Pump related.
