Floods and leaks have been a major problem in the Washington, Baltimore and Frederick Metro areas over the last few months. These recent floods have left many people worried about how to protect their homes from both rising water and internal leaks. Our new Wi-Fi enabled messenger indoor alarm system monitors and reports any residential alarm condition, including sump high water level, storage tank levels or over/under temperature alarms.

The alarm notifies the user both locally (audible and visual alarms) and remotely via text messages and/or emails to a smartphone, tablet or computer using your existing Wi-Fi network or Ethernet. The alarm is capable of notifying up to four contacts (two email, two text contacts) for alerts, including alarm, power lost, power restored, low battery and alarm offline.

Unlike similar products, this alarm does not rely on cellular service, so there are no contracts to sign or monthly fees to pay. It comes with automatic alarm rest and 9-volt DC battery backup with low-battery chirp. The touch pad includes test and silence buttons for the alarm horn and LED indicators for alarm (red), power on (green) and network status.

Learn more about this alarm system as well as additional flood & leak control and/or prevention by calling or emailing National Water today at 301-854-1333 or info@nationalwaterservice.com.

The U.S. General Accounting Office reports that there are serious deficiencies in water treatment plants in 75% of the states. More than 120 million people (about 50% of the population) may get unsafe water according to a study conducted by the Natural Resources Defense Council. “The chlorine used to reduce the risk of infectious disease may account for a substantial portion of the cancer risk associated with drinking water.” Do you know what is in your water. National Water has spent the last 40 years educating our customers on their water and working with them to create a water treatment specific to their individual needs.

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 feeder 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 water contamination, including  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 Chemical Feeder is right for you or you would like additional information, please email National Water at info@nationalwaterservice.com or call us at 301-854-1333!



Groundwater or well water is water that can be found under the earth’s surface. It’s stored in the cracks and spaces between particles of soil, sand and rock. Well water may naturally contain many different impurities including bacteria, sediment, radon, coliform, e-coli and more. Groundwater can also become contaminated when man made pollutants seep into underground aquifers.

Our customers well is located next to a city street in Randallstown, MD. The well became contaminated with salt from trucks treating roads before snow storms. To remove the salt from the well water we installed a 2000 gpd whole house Reverse Osmosis (RO) system. The RO purifies water by forcing the brackish water through filters and a membrane. Reverse Osmosis systems remove up too 99.9% of all contaminants from water.
We installed a water softener and filters for both sediment and turbidity.  After the RO, we added 800 gallon clean water storage tanks. We added a Chemical Feeder to control pH  and corrosion. We installed a booster pump to increase water pressure.
A professional water technician must be able test your water quality and install the proper remediation.  Water Treatment is the consumer friendly answer to all of your water wants and needs.  

A lot of attention, and rightfully so, is being paid to lead in our nations water supply. However, recently more contaminants are being tested for and found in our tap water. From different types of bacteria such as e-coli and coliform to fluoride and chlorine, our tap water is not what we expect it to be. Now, prescription drugs from stimulants and sedatives to tranquilizers and opioids are in the water our families use! It’s time to make changes before its to late. If your local water company won’t, perhaps its time to look into the different water treatment options available to you in your home and office! Water Treatment is for everyone! 

The #1 Reason Why You Must Stop Drinking Tap Water

Radon causes cancer and is found in both air and water. Over the last 12 to 18 months we have tested hundreds of homes in Maryland for Radon in their well or ground water.
Per the US Geological Survey, central Maryland has some of the highest levels of Radon in groundwater. Radon is the #1 natural cause of lung cancer and the #6 cause of cancer overall in the US. Radon accounts for over 21,000 preventable deaths per year according to the CDC.
If your home is on well water, have your water tested, it could save a life.


Every Tuesday morning we have a continuing education meeting. We discuss new products and advancements in well pumps and water treatment technology, we invite speakers and discuss our customers experiences over the previous week and how we can improve. We also look at what jobs we have coming up and make sure everyone in the office and in the field is ready! Nothing is more important to National Water then our techs being knowledgeable and prepared for our customers!

Radon is the leading natural cause of lung cancer in the United States and the sixth leading cause of all cancers. Radon is found in both air and water, however, unlike in air, water testing is not required. In the Mid-Atlantic region, radon levels can be dangerously high, over 100,000 pCi/L.  

Central Maryland and Virginia have some of the highest concentrations of Radon in water in the country. Homes in central Montgomery, western Howard, eastern Frederick and central Carroll Counties in Maryland are most at risk. These include houses built on the Piedmont Province, particularly those built on the zone of phyllites. 

The only way to know whether your home has elevated radon levels is to test your home. Despite radon’s effect on the body, most locations don’t require a water test. The EPA and most States only require Radon to be tested in your air, potentially putting peoples health at risk. Have your homes water tested for radon, it could save a life!

Lead in water is not only a problem for residents of Flint, Michigan or Washington, DC, it effects everyone. In August 2018 it was reported that students at 90 Montgomery County, MD public schools may have been exposed to lead. The lead concentrations were higher than the EPA’s “action level” of 15 parts per billion.

Lead is a naturally occurring, common metal found throughout the environment. However, lead  is seldom found naturally in water supplies, such as lakes and rivers. Lead enters drinking water due to corrosion or wearing away of municipal water pipes and household plumbing containing lead.

A toxic metal, lead can cause both immediate and long term health effects. Lead can cause damage to the brain and kidney, as well as have serious effects on blood. Children are the most vulnerable to lead poisoning due to their smaller, still developing bodies. Pregnant women are also at higher risk for negative health effects associated with lead exposure.

Changes to Lead in Water laws

In 1991, the EPA’s new Lead and Copper Rule, requires municipal or public water systems regularly test for lead. If more than 10% of homes tested have lead concentrations higher than the EPA’s “action level, ” the public must be informed.  Individual water companies are required to notify area residents via social media, TV, radio, phone calls, etc. The EPA is currently considering long term revisions to the Lead and Copper Rule. 

Revisions to the Safe Drinking Water Act in 2014 made it illegal to install any pipe, fixture or fitting not “lead free.”  Due to this change, all plumping pipes and fixtures must not contain more than 0.2 percent lead. As such, all installations or repairs of a municipal water system or consumers plumbing must be lead free. 

However in 2016, USA Today reported that 2,000 water systems, in all 50 states, had excessive lead contamination. The water systems, which reported lead levels exceeding EPA standards, collectively supply water to 6 million people. Per the Safe Drinking Water Act, older homes are more likely to have plumbing fixtures containing lead.

If you’re concerned about lead in your drinking water, National Water is here to help. Call today to learn why in-home water treatment is the consumer friendly answer to your families water wants and needs.
