TESTING YOUR WELL WATER

Test your well water once a year for bacteria and nitrates and every 3 to 5 years for arsenic, fluoride, uranium, radon, lead, and manganese.
If you have never tested your well water, we recommend doing a comprehensive test. Other times to test your well include:

• If you are expecting a baby
• Your water changes in smell, taste, and color
• Your well runs dry and comes back
• When buying a new home
• After installing a water treatment system or replacing parts of your treatment system
• After any work is done on your well

It may be necessary to remove a contaminant from your water because it’s unsafe or unhealthy to be consuming. Some examples are arsenic, nitrate and volatile organic compounds. Or you may want to remove something that is simply undesirable because it changes the taste of your water, makes your water hard, or stains your clothing. Iron, manganese, calcium and magnesium are examples of contaminants that are not dangerous, but are undesirable, so homeowners often seek to remove them.

There are three types of affordable water treatment systems commonly used in private homes to treat water for a variety of contaminants: water filtration, reverse osmosis, and ion exchange.

Affordable Water Filtration Systems

Water Filtration is the simplest method of treating water. Water is forced through some physical barrier, with larger particles either “sticking” to the media, or they simply can’t fit through the pore spaces in the media and are “trapped”. Activated carbon filters have tremendous surface areas for contaminants to adhere to. They are effective at removing many contaminants that change the taste and odor of water, especially organic compounds. They are also very good at removing some radioactive elements like radon and uranium. Carbon filters are not effective at removing most inorganic compounds and should not be relied upon to remove arsenic, nitrates, or other inorganics. Finally, filters should not be used to remove anything that’s dissolved in water. It was a chemical reaction that caused the contaminants to dissolve, and will likely require a chemical reaction (ion exchange) or filtration at the atomic scale (reverse osmosis) to remove

Ion Exchange

Ion exchange involves the swapping of an undesirable ion in your water with one that has similar chemical properties but does not have negative effects on water quality. Water softeners are the most common ion exchange systems in use in most homes. These systems can also remove iron, manganese, nitrate and, if properly designed, arsenic.

An ion is any atom or compound that has either a positive (cation) or negative (anion) charge, like the poles on a magnet. A positive ion will be attracted to a negative charge in the same way the “north” pole of a magnet is attracted to the “south” pole of another magnet. The “magnet” in these systems is usually a man-made polystyrene resin. The process begins with thousands of resin beads with sodium cations attached. As water passes through the resin beads, cations like iron, manganese, or calcium, knock the sodium cations off and replace them. This is possible because the sodium cations have a weaker charge. After a period of time, the available locations for this exchange to take place start to be used up. At this point this affordable water treatment system will “regenerate” itself. A brine solution is washed over the resin beads and the billions of sodium cations in the solution force themselves back into place, removing the iron, calcium, or other cations, and flushing them into a septic system or sewer.

Reverse Osmosis

Along with whole-house filtration systems, we offer Reverse Osmosis systems, an affordable and highly effective filtration option for drinking water at the kitchen sink.

The most cost-effective method for removing arsenic and many other inorganic and organic compounds from a domestic water supply is to be reverse osmosis (RO). RO can be loosely thought of as atomic scale filtration. It works by squeezing water through a special membrane. The membrane has microscopic holes, which are specially sized to allow relatively small water molecules to pass through, while trapping larger inorganic elements like lead, iron, chromium, and arsenic or organic compounds. Studies have shown RO to be up to 95% effective at removing the most common form of arsenic routinely found in Maine well water. RO requires very little regular maintenance, no chemical addition, is very reliable, and installation is fairly straightforward. The RO system most homeowners have installed is a point of use system, designed to treat only a small amount of water daily. It is usually located near the kitchen sink, and is capable of producing two or three gallons of treated water per day. It consists of a particulate pre-filter which removes sand and grit, the membrane where the reverse osmosis occurs, and an activated carbon polishing filter to aid in taste and odor control. Treated water is stored in a small tank and is accessed through a faucet located next to the regular kitchen faucet.

Most wells in Maine use the rotary drilling method for a well installation – a drill bit is attached to a length of connected drill pipe. The drill bit is made of a tough metal such as tungsten, and as the drill is rotated, the bit acts to grind up the rock. The broken pieces (cuttings) are flushed upward and out of the hole by circulating a drilling fluid (sometimes called drilling mud) down through the drill pipe and back to the surface. This drilling fluid also serves to cool and lubricate the drill bit. By stabilizing the wall of the hole, it can prevent possible cave-in of unstable sands or crumbly rock before the well casing or well screen is installed.

As the drill intersects water-bearing rock formations water will flow into the hole. We carefully monitor the depth of water “strikes”, and keep a note of the formations in which they occur. In areas of hard rocks we use a well installation drilling technique that uses compressed air to operate a down-hole air hammer on the end of the drill string that helps to break up the hard rocks. The compressed air also blows the crushed rock fragments out of the hole to the surface along with any water that flows in the well during drilling.

In low yielding wells it is sometimes possible to increase yield by using “hydrofracking” techniques. In this process, selected parts of the drilled hole are subjected to great pressure using special tools lowered from the surface. The expected result is that small existing fractures will be enlarged or opened up to allow the well to connect to additional water bearing fractures or fissures.

No matter which method of drilling is used, the top part of the well is usually lined with steel or plastic well casing. The diameter of the drilled hole is usually an inch or two wider than the diameter of the casing. The space between the drilled hole and the casing (the annulus) has to be filled to prevent the chance of polluted surface water from migrating downward along the outside of the casing where it might contaminate the aquifer. Sometimes most of the space is filled with the fine rock pieces from drilling and then the top 20 feet is grouted.

A modern water well installation is much more than a hole in the ground. There is a lot of experience and knowledge required to dig a stable and productive well.

Hydro-fracturing involves using specialized high pressure pumps to inject water under high pressure into bedrock via the well. It involves lowering down into the well one or two inflatable hard rubber “sleeves” or “balloons”, technically called Packers. First, all pipes, wires and the pump need to be removed from the well. The packers are then inflated to seal off a section of the well. The packers are usually set a minimum of 40 feet below the end of the casing and 60 feet below ground surface.

Water is pumped at high pressure into the section of the well between the packers, or below the packer if only one is used. Most hydrofracturing equipment for private wells can provide between 500 and 2000 psi (pounds per square inch) of pressure, sometimes up to 3,000 psi. Up to 50 gallons a minute is usually adequate as a pumping rate for adding water into the well. The water pressure within the sealed-off section of the well will rise as the surrounding rocks resist the flow of water out of the well.

A sign of successful hydrofracturing is a sudden drop in the pressure indicating that the surrounding rocks are accepting water. If more fissures have been opened there is often a strong backflow of turbid water when pumping into the well is stopped. 

The cost for single packer hydrofracturing is usually less than when a double packer system is used. A double system allows for a selected zone in the well to be pressured by inflating both packers. The packers are usually first set near the bottom of the well and then moved up to another section. Selection of the zones to pressurize may be made from information on the well drillers log or from a down-hole camera survey.

So what does one do when they see that their Arsenic levels are above the EPA levels? The Homeowner typically becomes scared and refuses to consume or even bath in their water. They fear that they are going to turn green (no really, I have heard this many times). What do they do next? They start to research on Google. Unfortunately, Google search is not the best approach when finding out treatment methods as it can lead you to making impulsive decisions, over spending, or even more so, fall for scare tactics.

First thing you can do is take a deep breath and start drinking and cooking with bottled water. The next step is to educate yourself on what Arsenic is and how it can affect you and your family. Lastly, forgive yourself for not being aware that a colorless, odorless, and tasteless element was found in your water.

The next steps are to get in touch with a Company that specializes in water treatment. While doing this keep in mind that much like Car Dealerships some Water Treatment Companies have Sales People. Some salespeople are reputable while others over sell.

During this crucial part of the process keep the following in mind:

• The best way to search for a reputable Company is receiving as many different quotes-this is a good way to deter those over sellers out.
• Ask for references. If they are in Business then they should be able to provide you with a list of Happy Customers you can contact directly.
• Request Proof of licenses/insurance. Make sure they are following the law and have all the appropriate licenses.
• Ask for future costs of Service. The initial cost of the system may be reasonably priced, but how much would the system cost to keep it running? Have them break down the cost for you.
• Ask if there is more than one option of Treatment.
• Ask about their Guarantees and Warranties.
• Read over the Contracts (make sure to read the fine print).
• Allow yourself sometime to make a decision.

Whole House Point of Use

9 out of 10 people will immediately request a Whole House quote. A trustworthy Company should evaluate your levels and provide you a logical reason as to why they recommend that option.

Here is why:
If your Arsenic levels are above 100 ug/L then a Whole House option should be considered. The reason behind this is because Arsenic is absorbed through the skin at a 10% absorption rate which would in fact make the levels above the limits when bathing. Keep in mind that there are different treatment options for a Whole House Arsenic Removal System and here are some steps to follow:

• Will it take out both Arsenic #3 & #5? There are two types of Arsenic, a good way to remember the difference is Arsenic #5 is like a high five- it’s easier to remove and takes up less space in a tank. Reverse Osmosis and Anion Softeners will only remove Arsenic #5.
• Ask if there are any swap out tank charges and how frequently they will need to be replaced when they are exhausted.
• See if there are options available to by-pass certain faucets or fixtures. This is important and I always like to explain to customers that every time you run your washing machine, wash your car, or flush your toilet the water is being treated and the life of the tank/filter is greatly reduced. Therefore, if they are able to by-pass unnecessary fixtures it can be very beneficial.

Once the Customer is aware of these differences 9 out of 10 will choose a Point of Use System just treating the Kitchen sink. Most of the reasons are due to finances and that there is a substantial difference in pricing between the two. Keep in mind that when levels are below 100 ug/L treatment options are a preference so do what is best for you and your family.

Radon is a radioactive, carcinogenic gas, and one of the many naturally occurring chemical element that make up different types of bedrock. It has no color, taste, or odor, even at very high levels. Radon gas seeps into our homes through foundation materials built on bedrock, and when it is agitated as water is delivered through fixtures and becomes airborne. Even houses built on slabs can emit dangerous levels of radon. Homes without foundations can also have high levels of radon gases present. Houses over sand and gravel most commonly test at higher levels.

It is the number one cause of lung cancer among non-smokers and is responsible for about 21,000 lung cancer deaths yearly. About 2,900 of these deaths occur among people who have never smoked.

Radon can enter your home in many ways, the most common being:

• Cracks in foundation materials
• Cracks in foundation walls
• Gaps around utility services (pipes, vents, exhausts)
• Sump pump holes
• Your water supply

Does My Home have Radon?

The Environmental Protection Agency and the State of Maine consider a radon test level over 4 pCi/L (picocuries per liter) in the air and 10,000 pCi/L in water, as an average level, to be dangerous. it can be found in elevated levels ANYWHERE in Maine. In fact, the average residential radon level in the state is 4.1 pCi/l, and even higher in the southern portion of the state. Most of the radon in Maine homes comes from the soil gasses, but is also prevalent in the groundwater derived from drilled wells.

Should I have a Test?

Simple, affordable radon tests can reveal what the radon level is in your home air and/or water. High levels can be mitigated with very straightforward and affordable systems that can be installed in a short period of time.

If you are at all concerned:

• Have testing done so that you know what your radon levels are.
• Retest your home every two years.
• Retest any time you make structural changes to your home.
• Test or retest if you plan to finish your basement into a living space.

At A-Z Water Systems, we are certified to test for radon in water, and offer mitigation system solutions that work quickly and effectively. Please contact us for a FREE consultation.
