Since the 1940’s, most Americans have been told of the health benefits of adding Fluoride to our water, our toothpastes and to “gargle and spit” while at the dentist. However, recent studies by the world’s oldest and prestigious medical journal, The Lancet, have officially classified fluoride as a Neurotoxin, the same category as arsenic, lead and mercury. The report specifically notes that neuro-developmental disabilities from fluoride including attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, are now affecting millions of children worldwide in what they call a “pandemic of developmental Neurotoxicity.” If you’ve ever noticed the warnings on toothpaste labels you probably know just how serious fluoride poisoning can be, especially for children if they swallow too much at one time.

The report in The Lancet coincides with 2013 findings by a Harvard University meta-analysis funded by the National Institutes of Health that concluded that children in areas with highly fluoridated water have “significantly lower” IQ scores that those who live in areas with low amounts of fluoride in their water supplies. In addition, Fluoride can lead to dental and skeletal fluorosis, or a hardening of your bones and joints, resulting in higher risk of fractures or breaks. Cardiovascular problems have also been linked back to fluoride, including high blood pressure, arteriosclerosis, cardiac insufficiency and even heart failure.

Due to these findings most developed nations in the world have rejected fluoridation, including 97% of western Europe. The United States, which fluoridates more than 70% of its water supplies, is an exception to this rule. According to the British Fluoridation Society, there are more people drinking artificially fluoridated water in the United States than all other countries combined. The Center for Disease Control (CDC), a main proponent of fluoride, stated that “as a result of water fluoridation, dental caries declined precipitously during the second half of the 20th century.” However, what the CDC has failed to mention is that tooth decay rates have “precipitously declined” in all western countries, irrespective of whether the country ever fluoridated its water. 

Despite these reports, most Americans consider fluoride to be an important part of our countries water purification.  All water treatment chemicals, with the exception of fluoride, are added to make drinking water safe and pleasant to consume. Fluoride is the only chemical added to treat people who consume the water, rather than the water itself. Fluoridating water supplies can thus fairly be described as a form of mass medication, which is why most European countries have rejected the practice. However, personal, in-home, water treatment systems, such as a Reverse Osmosis or Carbon tanks or filters can be used to remove fluoride from water.

Lead in water is not only a problem for residents of Flint, Michigan or Washington, DC, it effects everyone. In August of 2018, water tests revealed that students at 90 Montgomery County, MD public schools & 19 public schools in Anne Arundel County may have been exposed to  high lead concentrations above the EPA’s “action level” of  15 parts per billion.

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

Lead is a toxic metal that can cause immediate effects at high doses and long term effects if it builds up in the body over many years. Lead can cause damage to the brain and kidney and has serious effects on your blood. Children are the most vulnerable to lead poisoning because their bodies are smaller and still developing. Pregnant women are also at higher risk for negative health effects associated with lead exposure.

In 1991, the EPA published the Lead and Copper Rule that requires all municipal or public drinking water systems regularly test a sample of homes for lead at the tap. If more than 10 percent of homes tested have lead concentrations higher than the EPA’s “action level”  individual water companies are required to notify area residents via any means necessary including social media, TV, radio, phone calls to customers and more. The EPA is currently considering long term revisions to the Lead and Copper Rule.

In January 2014 revisions to the Safe Drinking Water Act made it illegal to install any pipe, or plumbing fixture or fitting during installation or repair of a municipal water system or  customer’s drinking water plumbing unless it meets the definition of “lead-free” or not containing more than 0.2 percent lead.

However, in 2016 USA Today reported that they have identified around 2,000  water systems spanning all 50 states where testing has shown excessive levels of lead contamination over the past four years. The water systems, which reported lead levels exceeding EPA standards, collectively supply water to 6 million people.

As a result of the revisions to the the Safe Drinking Water Act & the Lead & Copper Rule, older homes are more likely to have plumbing fixtures containing lead.

If you’re concerned about lead in your drinking water or would like to learn more about why in-home water treatment is the consumer friendly answer to your families water wants and needs, please call us at 301-854-1333 or by  email at

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/Lin 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 40,000 pCi/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. 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.

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!

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!
