Etching is the erosion of the surface of glassware, tiny pits or “scratches” on the glass. Sometimes you might some effervescent coloring on your glasses in the early stages. Sometimes a milky color that will not dissolve off or it might look like it has been lightly sandblasted. Etching can happen in any dishwasher, doesn’t matter if the water used to clean the dishes is soft or hard water, although it is more commonly occurs when the water has been mechanically softened by a water softener. It can also happen to any grade of glassware. Dollar store glass or top notch glass. The cause of etching on dishes can be from too much detergent in soft water, items that are pre-rinsed multiple times, or washing dishes in water that is too hot.
Glassware damaged by etching can’t be fixed. But it can be stopped. Try changing the amount or type of detergent that is used. Also, try checking the temperature of the incoming water. Go to a faucet near the dishwasher, then turn on the hot water for around 45 seconds or till the water gets hot. Then run water in a glass and place a thermometer in the glass and check the temperature. It should be within 120-140 degrees.
For another quick fix to etching problems stop pre-rinsing dishes. Detergent needs the grim and food left on the plates to work the way it was designed to work. If there isn’t food or dirt on the dishes the detergent works away the outside layers of the glassware.
It is a challenging problem when encountered & is gradual & usually does not occur overnight. Typically when you notice the results of etching the damage has been done. It requires some experimentation to find the correct formula of detergent and water supply to solve the problem.
You can perform a simple test to see if your dishes are etched or if they are simply coated with mineral & soap build up. Put some lemon juice on a small area of the effected glassware & allow it soak for 5-10 minutes then wash it off. Allow the glass to dry. If that spot you put the lemon juice on is much cleaner than rest of the glass than it is not etched & can be restored. If the spot you put the lemon on looks unchanged then it is most likely etched.

Water Treatment is not only for homes! We recently installed a twin KX Pro Commercial water treatment system to effectively reduce iron and other heavy metals from the Gary J. Arthur Community Center in Glenwood, MD.


A Water Treatment installation for a customer in Potomac, MD. He decided to build a new shed to house his Radon reducing Spruce AiRaider, three Water Storage Containers with a Leak Detection Alarm, a Constant Water Pressure System, a Chemical Feeder and Solution Tank for pH and corrosion control, a Whole House 20 inch Sediment Filter and a Water Pressure Tank. 

A great way to easily access his equipment without taking up space in his home!


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 below, to help them identify what exactly they have treating their water!



One of our most important jobs is emergency response. Whether we are dealing with current or new customers, businesses or home warranty company clients, if you have no water or low pressure we are here to help, 24 hours a day, 7 days a week, 365 days a year.

Last week we had many no water calls. We replaced well pumps, water logged pressure tanks, broken control boxes for a constant pressure system and a few thousand feet of pipe and wire.
If you have No Water please call us 301-854-1333 or email!


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. To learn more about the effects of fluoride and how to remove it, as well as other impurities from your water, please contact National Water Service at 301-854-1333 or by email at 

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.
