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. 

Groundwater or well water is water that can be found under the earth’s surface, stored in the cracks and spaces between particles of soil, sand and rock. Well water may naturally contain many different impurities including, but not limited to, bacteria, sediment, radon, coliform, e-coli and more.

Well water can also become contaminated when pollutants on land seep into underground aquifers. Our customers well is located next to a city street in Randallstown, MD and became contaminated with sodium chloride (salt) from trucks pre-treating roads before snow storms.

To remove the salt from his now brackish well water we installed a 2000 gallon per day whole house commercial grade Reverse Osmosis (RO) water treatment system. The RO forces the brackish water through the filters and membrane, capturing & removing 99.99% of all contaminants, including the salt.

In addition to the RO, we installed a water softener, turbidity filter, sediment filter and an 800 gallon storage tank to hold the now clean water. We installed an Ozone Bubbler for tank disinfection, a Chemical Feeder to control the pH of the RO water and booster pump to increase the water pressure for the entire house.

No matter if your well water is contaminated by natural or human causes, a professional water technician will be able test your water and install the proper remediation. Water Treatment is for everyone!

At National Water our technicians must be prepared for any situation, including turning a service visit into a sales appointment. Every Tuesday morning we hold continuing education meetings so that our techs are up to date on the latest water treatment/filtration/purification and well pumps in the industry.

We were called by a new customer in Woodbine, MD who had very low water pressure as well as a water softener, acid neutralizer and a Reverse Osmosis System that had not been serviced in years. The customer also asked that we have the well tested for Radon, bacteria and other contaminants in her water. The tests came back positive for e-coli, other bacteria as well as very high levels of radon in the water.

We installed a Spruce Airaider for remediation of radon in water with a booster pump. We dumped and re-packed the water softener and acid neutralizer with appropriate resin and calcite, installed an ultra-violet remediation system that removes 99.9% of bacteria from water and changed the filters and membrane in the Reverse Osmosis. In addition, we installed a new whole house sediment filter and a well pump control box with pressure tank that converts a standard well pump into one with constant pressure. Finally, we installed a new Hot Water Heater. We re-plumbed the entire water treatment system and installed leak detectors and isolation barriers to prevent any damage should a leak occur.

Our very satisfied new customer now has safe, clean, radon and bacteria free water for her and her entire family to use without worry!

One of the most commonly used, but misunderstood, Water Treatment systems is a Chemical (Chem) Feeder. A Chem Feeder is among the most effective, versatile, and cost-efficient water One of the most commonly used but misunderstood water treatment systems is a Chemical Feeder. A Chemical Feeder is among the most effective and economical ways to treat your waters pH and odor issues.

One of the main purposes of a chemical feed system is to control the pH of your water. The system measures the amount of water used and pumps different chemicals, including, but not limited to, sodium hydroxide (caustic) or soda ash into a mixing tank at the appropriate amount to ensure that the pH of your water is neutral or around 7.2.

Chemical feeders are also very effective in treating certain types of bacteria, iron and manganese as well as eliminating odors such as hydrogen sulfide (rotten egg smell) that may be coming from your well water by adding chlorine to the mixing tank.

Working in conjunction with your other Water Treatment equipment, a Chemical Feeder allows you to control the pH of your water and eliminate any corrosion that may occur in your plumbing.

If you think a Chem Feeder is right for you or you would like additional information, please email National Water at or call us at 301-854-1333!

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, commonly referred to as RO, by definition, is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. A Reverse Osmosis water treatment system  is capable of removing up to 99% of all contaminants from water, including, but not limited to, pharmaceuticals, dissolved salts (ions), organic particles and bacteria, including e-coli.


An RO works by forcing water through different filters in order to remove all impurities before reaching the membrane and finally your faucet. The first filter is a sediment filter to trap particles, including dissolved solids such as calcium carbonate, a second sediment filter with smaller pores to catch the smaller sediment, an activated carbon filter to trap organic chemicals and chlorine, which will attack and degrade reverse osmosis membranes and finally through the thin film composite membrane. Once the water passes through the pre-filters and membrane it is so pure it needs its own waterline and faucet, designed specifically for RO’s. 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, cooking and more 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 or in a basement area where lines can be run to multiple faucets, refrigerators or ice makers. The price of an RO fully installed in your kitchen is about the same price the average family of 4 spends on bottled water each year!! Clean water and preventing more plastic bottles from entering our landfills is the perfect way to stay Green in 2017! In home RO systems provides endless safe, healthy, clean water for you and your family!

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 (pc/L). The EPA recommends that homes with Radon levels of 4 pc/L in the air have remediation installed in the home. 10,000 pc/L of radon in water adds 1 pc/L to radon in the air. Levels below 4 pc/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 40,000 pc/L) of radon in wells all around the Washington and Baltimore Metro Regions, specifically in Montgomery and Howard Counties, in Maryland. 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.

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 30 years, National Water Service has been serving the entire Mid-Atlantic regions well water, well pump and water treatment, purification and filtration needs!
