What it is: Hard water contains calcium and magnesium minerals which bond with everything they touch leaving “limescale” in their wake.
Treatment – Our guaranteed home water softener offers the best option for soft water on the market. It improves the water throughout your entire home while protecting your appliances and fixtures.
What it is – Iron can come in a couple different forms including dissolved and undissolved. Both of which can leave red/orange stains on your sinks, tubs, and toilets and can be extremely hard to remove. Iron can also cause bacteria to grow and let off an unpleasant smell.
What it is: Exactly as it sounds. This is typically most common in well water or surface water that hasn’t gone through a treatment facility.
Treatment – Dirt and sediment are found in almost all water supplies and will decrease the productivity and lifespan of your appliances. For example, sediment in a water heater can prevent the heat from transferring to the water in the tank once sediment has built up in the bottom. Our whole house filter system can help with this problem.
A new study by the Environmental Working Group reports that local drinking water contains hexavalent chromium, a toxic metal that has been linked to cancer. While the U.S. Environmental Protection Agency does not require testing for the metal, the survey found that levels in our local water were pushing the levels proposed as a safety limit by authorities. This contaminant has been proven to cause cancer. You can search your zip code to see the amount in your municipal water supply here.
Arsenic is a common water issue in Indiana, however, it can be easily and affordably removed with an under-sink Indiana water filter from Aqua Otter.
According to the CDC, “Arsenic can enter the water supply from natural deposits in the earth or from industrial and agricultural pollution. It is widely believed that naturally occurring arsenic dissolves out of certain rock formations when groundwater levels drop significantly. Some industries in the United States release thousands of pounds of arsenic into the environment every year. Once released, arsenic remains in the environment for a long time. Arsenic is removed from the air by rain, snow, and gradual settling. Once on the ground or in surface water, arsenic can slowly enter groundwater. High arsenic levels in private wells may come from certain arsenic-containing fertilizers used in the past or industrial waste.”
What they are: common contaminants in our area can include nitrates, lead, arsenic, tannins, and more. These are not included in the free water test, however, we do offer full laboratory testing at an affordable price.
Treatment – Protecting the water in your home is important, however guaranteeing the purity of the water you are putting in your body is even more vital. Our reverse osmosis water treatment system will let you know that your drinking water is healthy, and you are going to fall in love with this drinking water system that can supply up to 50 gallons per day of delicious water.
What it is: Tannins are natural chemicals found in plants like tree bark, leaves, and fruit peels. When they get into water, they can make it look yellow or brown and taste bitter. You'll often find tannins in surface water and shallow wells, especially in areas with lots of plant material.
Water with tannins can taste bad and look unappetizing, which might make you drink less water or look for other sources that could be unsafe. Some people may get stomach problems if they drink water with high levels of tannins for a long time. Tannins can also stick to proteins and minerals in your body, which might make it harder for you to absorb important nutrients like iron if you drink large amounts.
There are typically two water contaminants that can cause your water to smell like sulfur or rotten eggs, one is Hydrogen Sulfide (H2S) and the other is iron or sulfates.
H2S is a mineral that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.
Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.
The most important thing to note is that it is ALWAYS worthwhile to get your water tested as H2S poses a serious potential health risk including nausea, vomiting, and other serious health effects.
Water in our area has frequently been positive for lead, cysts, and PFOA/PFOS. These chemicals have been found to exceed the levels set forth by health advisory organizations and may cause health problems.
The chemicals Perfluorooctanoic acid (PFOA), also known as C8, and Perfluorooctane Sulfonic acid (PFOS) are bio-permanent, resistant to direct oxidation, and do not break down naturally in the environment or the human body. Studies suggest that exposure to these chemicals may lead to cancer.
Iron Bacteria: Microorganisms that thrive in iron-rich well water, causing slimy, rust-colored deposits in plumbing, fixtures, and water softeners. While not harmful to health, they clog pipes, create odors, and promote bacterial growth. Filtering them out prevents plumbing issues and improves water quality.
Sulfur-Reducing Bacteria (SRB): These microorganisms feed on sulfur compounds in well water, producing hydrogen sulfide gas, which smells like rotten eggs. SRB can corrode pipes and stain fixtures. Removing them eliminates odors, protects plumbing, and ensures better water quality.
E. coli: Indicates fecal contamination in well water, often from sewage, agricultural runoff, or animal waste. Certain strains can cause serious illness. Filtering out E. coli is crucial for safe drinking water.
Chloroform: A byproduct of chlorine disinfection or industrial pollution. Long-term exposure poses health risks, including liver and kidney damage. Filtering it out improves water safety and quality.
High levels can cause black staining on fixtures, metallic-tasting water, and sediment buildup in plumbing. Filtering manganese prevents staining, protects appliances, and improves taste.
