Water Systems

Water quality can affect your home, your appliances and your health. Your water pipes bring iron, manganese and other hard elements into your home which can affect the efficiency of appliances. Your health can be affected by natural elements such as radon, uranium and arsenic that may be found in your water.

Maine Radon Solutions can test and treat your water by creating a water treatment solution. Below are the most common issues we treat. If you are experiencing an issue that is not listed below, please contact us.

Radon Water Mitigation/Removal

Aeration - Maine Radon Solutions uses this water treatment solution in the vast majority of homes and it is typically the solution we recommend first. The radon gas is released by air bubbles in the water. Venting will then remove this radon to the outdoors.

This solution minimizes the buildup of radioactive materials. An aeration unit will require the water to be repressurized after it is treated, and care must be taken to ensure the radon gas is properly vented outdoors. The venting must be done above the roof line and have an auxiliary fan to ensure safe removal of the radon gas.

GAC (Granular Activated Carbon) - This technique utilizes activated carbon to absorb the radon gas from the water. Once the radon is absorbed, it will decay in the carbon. We can only implement this solution if the radon concentration in your water is low enough to meet EPA standards.

Uranium Removal

Uranium treatment is necessary if the concentration of uranium is above the EPA’s maximum allowable exposure levels. Uranium in drinking water is tasteless, colorless and odorless. Your water must be tested to see if it contains uranium. These are the practical ways to treat uranium removal in a residential situation:

Ion exchange with anion resin: This is the most common and effective way to remove uranium from your water.

Reverse osmosis:This can be the point-of-use or point-of-entry. Point of entry RO would be the most expensive but removes many other contaminants.

Arsenic Removal

Arsenic filtration media: our most common method for point-of-entry (whole house)
Anion resin ion exchange
Reverse osmosis: our most common method for point-of-use (ie kitchen sink)

Hard Water

Hard water is the result of dissolved calcium and magnesium. They become less soluble at high temperatures and form a white solid. This characteristic is what causes most of the problems with hard water. The most recognizable symptoms of hard water are soap scum in the shower or tub and hard water spots. Hard water can leave mineral deposits in hot water heaters and tankless coils, reduce the efficiency of these units and completely block passages in and out of the heaters.

Water softener:This is the only treatment for hard water in a residential situation. It can be often used in conjunction with another system if multiple elements are being treated.

Iron and Manganese

Iron will cause your water to have a metallic taste and odor as well as an orange stain. If it is accompanied by manganese it will cause a chocolate brown stain and may contain a hydrogen sulfide gas odor. Water treatment for iron depends on the form of iron in your water.

Various water conditioners or filters can be used to treat your water depending on the form in which the elements exist and the water chemistry.

Ferrous Iron: This is most often referred to as clear water iron and is dissolved in the water. These materials cannot be filtered and must be removed with the help of chemical changes. Ferrous iron can be removed be either using a water softener or a two-step process called oxidation filtration.

Ferric Iron:This is referred to as red water iron because it will give the water a cloudy reddish/orange appearance. This is rust and is the result of ferrous iron once it oxidizes. This type of iron can be filtered. Ferric iron is removed by filters since the iron is already oxidized.

Organic Iron:This is sometimes called heme-iron or pink water. This is actually iron combined with dissolved organic matter. This water will appear clear and only have color if the iron concentration is high enough. Organic iron is typically treated with an anion resin in tank that uses salt like a water softener.

Colloidal Iron:This will look like red water iron but is not easily filtered. The iron particles do not form large enough pieces to settle and be filtered. This type of iron is treated by flocculation or ultrafiltration.

Hydrogen Sulfide

Rotten Egg Smell

This is a naturally occurring gas that can cause an odor that smells similar to rotten eggs. At high concentrations, it can cause a black stain when oxidized in water. In order to treat this, the source must be determined. It can be created by decaying organic matter, from the reaction of acidic water with an aquifer that has a sulfur content, or from the byproducts of bacteria that use iron or manganese as part of their diet. Once the source is determined, there are various methods that can be used to remove hydrogen sulfide.

Air-Oxygen System: This process uses oxygen in the air to oxidize the hydrogen sulfide. It can also be called an air injection system.

Chlorination Systems: This process introduces chlorine to the water by one of two methods. The chlorine can be dropped in as a tablet form or pumped in with a solution feed pump. Water is sent to a retention tank and then to a filter. The choice of method is determined by the severity of the problem.

Greensand Systems: This method utilizes a catalytic media (called greensand) coated with manganese that is treated periodically with potassium permanganate. The potassium permanganate acts like an oxidant. When the hydrogen sulfide comes in contact with the surface of the media, it oxidizes and the sulfur is then filtered out by sticking to the media as it finds its way to the filter.

Catalytic Media Systems: This method uses a media similar to greensand. This is usually a naturally occurring mineral called manganese dioxide. This method relies on there being enough air in the water to provide oxygen necessary to turn hydrogen sulfide into sulfur.
