We are a Preferred Contractor

Water is essential to life. If you have unhealthy water, chances are you will soon have an unhealthy body. That is why water filtration systems are so important. If you’d like to learn a little more about this subject, read on. There is also a very helpful chart near the bottom of the page that explains some of the different contaminants or elements that occur in water and some of their effects.

Generally water filtration or water purification are terms for what is needed to remove undesirable chemicals, metals, bacteria and dissolved solids from water. Water softeners specifically address the hardness and minerals in water, although sometimes they are incorrectly used for iron filtration. (More on the subject of iron filtration here.) The goal of water filtration or purification is to produce uncontaminated water fit for drinking, living, and maintaining the longevity of your household plumbing systems.

Whether you have well water or city water, there are troubles with contaminants either way. If you need to clean up your water, fix a problem, maintenance your current filtration system, or just find out what the issue is, we’d love to help.

We are Water Treatment Providers with the National Water Quality Association, and are a Preferred Contractor with CSI Water Treatment Systems. We are fully trained and certified to offer a full range of water testing to determine the health and quality of the water that you drink, cook with, and bathe in everyday.

We install, repair, and maintain Water Softeners, Water Filtration Systems, Water Purifiers, Iron Filters, pH Neutralizers, Sediment Filters, Chemical Filters, UV Purifiers, Reverse Osmosis, and Chemical Water Treatment systems—everything you need to purify your water! Give us a call to discuss the Asheville area water filtration options that are available to you.

Do You Need Water Filtration?

Whether you have a private well or are using municipal water from Asheville or Hendersonville, there are dangers of contaminants or problems with your drinking water. You might not know if any of the contaminants listed below are in your water, but you need to know! That’s why we offer and recommend running our comprehensive water analysis. The tests we offer are collected in the field but analyzed in a laboratory, and test for over 100 different contaminants and elements, including bacteria, water quality ions, nutrients, minerals, metals and heavy metals. You will receive a detailed report of your water, and a quote for water filtration or purification, if needed. Once you know if any contaminants are there, we want to help you be rid of them for good! If your water is in good condition and no water filtration is needed, your test results will show that and you can set your mind at ease.

Even though we have all this information, we are plumbers, not doctors. The information provided here is to help educate you about water contamination and is not intended to diagnose or treat any medical problems you may have. Consult your doctor if you have any questions about that, but…

Consult Goodman Plumbing if you have any questions about water filtration, water treatment or water purification! We have had specialized training in water filtration and can design custom filtration systems to meet your specific needs.

We’d love the opportunity to talk with you about your water.

Understanding Common Water Contaminants

Water Filtration Info Chart

(Scroll horizontally to see full chart if necessary)

Name of Contaminant/Issue Description Negative Effects
Hard Water 85% calcium and magnesium mineralsfrom limestone, chalk and marble dissolved in water
  • Leaves deposits in hot water plumbing, which results in decreased water flow and low water pressure.
  • Leaves deposits in hot water heaters, which causes them to use 20% to 30% more energy to heat water.
  • Increases soap and detergent usage: 1.5 lbs of soap lost per 1000 gallons used.
  • Causes soap scum to form, which shortens the life of fabrics, causes difficulty in cleaning most surfaces, and can irritate the skin.
pH The acidity or alkalinity of water. Typically problems are caused by acidic water.
  • Acidic water can have corrosive tendencies, causing blue/green staining of tub, sink, or other fixtures for those with copper plumbing systems.
Iron & Manganese Comes from bacterial decomposition of natural organic matter. Ferrous Iron is a dissolved solid (clear) + oxidation. Ferric Iron is a suspended solid particle. Manganous is a dissolved solid (clear) + oxidation. Manganic is an insoluble suspended solid (dark brown/black particle). Iron Bacteria and Manganese Bacteria are living, non-pathogenic organisms (such as Gallionella, Crenothrix, Leptothrix).
  • Iron can leave deposits inside pipes and water heaters, causing decreased water flow and blockage.
  • Iron can cause fouling of water treatment equipment.
  • Usually, if iron bacteria is present, iron level will be high.
  • Iron can cause red or orange colored staining of plumbing fixtures and laundry.
  • Iron can also cause orange staining of sidewalks, buildings, and plants from irrigation.
  • Maganese can cause brown or black staining of plumbing fixtures and laundry.
  • Maganese is less likely to cause staining problems from irrigation system, but still possible.
Hydrogen Sulfide Gas Comes from bacterial decomposition of natural organic matter (vegetation). When exposed to oxygen, it changes chemically into elemental sulfur.
  • Can be accompanied by sulfur (sulfate) reducing bacteria, which are indicated by black, clear, gray or white slime growth in toilet tank.
  • Produces the distinctive “rotten egg” odor.
  • Very corrosive, tarnishes / oxidizes metals such as silver and copper.
Tannins Comes from decomposing natural organic matter (vegetation).
  • Can impart an “iced tea” color which can cause staining of plumbing fixtures and laundry.
  • Can make it difficult to remove iron/manganese.
  • Can coat water filter media and resins, causing them to fail.
Total Dissolved Solids (TDS) The total combined sum of all dissolved cations and anions.
  • At high levels, can give drinking water an unpleasant taste.
  • Certain cations and anions can pose health risks (nitrates, lead, arsenic, etc.)
  • High levels create conductivity that can contribute to electrolysis (corrosion of metal in plumbing fixtures).
  • Etching of crystal and glassware in dishwashers can occur.
  • Water spotting on plumbing fixtures, dishes, glassware, automobiles, etc.
Microbiological Contaminants Pathogenic (disease causing) organisms.
    Can cause serious illness. Some examples of biological contaminants are:
  • Bacteria (Coliform, E. Coli)
  • Cysts (Giardia Lamblia, Cryptosporidium)
  • Viruses (Hepatitis, Meningitis).
Nitrates Contaminants caused by fertilizers, animal manure, human waste, compost, or sewage sludge.
  • Can cause illness in cattle, sheep, and other ruminant animals.
  • Can cause iIllness in human infants (6 months old or less), known as the “Blue Baby Syndrome” (Methoglobinemia).
Chloride and Sulfates Chemicals limited by the Safe Drinking Water Act limit to 250 mg/l or less. Sulfates are usually present in water as sodium sulfate, calcium sulfate, or magnesium sulfate.
  • Chlorides will give water a salty taste.
  • Can cause extreme corrosion to metallic piping fixtures, piping, etc.
  • Will cause water hardness levels to be high.
  • If over 500 mg/l, both sodium & magnesium sulfate will give water a medicinal taste.
  • Sodium and magnesium sulfate can have a laxative effect.
Flouride A mineral commonly added to city water everywhere, and occurs naturally in groundwater in some locations.
    The EPA has stated that some of the negative effects of flouride are:
  • Increased likelihood of bone fractures in adults, and may result in effects on bone leading to pain and tenderness.
  • Children aged 8 years and younger exposed to excessive amounts of fluoride have an increased chance of developing pits in the tooth enamel, along with a range of cosmetic effects to teeth.
  • Other non-EPA sources list many other negative effects of flouride.
Radium / Radon Radon is a gas that has no color, odor, or taste and comes from the natural radioactive breakdown of uranium in the ground. Radon is a concern if your drinking water comes from underground, such as a well. Radium levels in drinking water may be high when it is extracted from deep wells that are located near radioactive waste disposal sites.
  • Exposure to higher levels of radium levels may cause teeth fracture, anemia and cataracts. When the exposure lasts for a long period of time radium may even cause cancer.
  • Drinking water containing radon presents a risk of developing internal organ cancers, primarily stomach cancer.
  • An increased risk of lung cancer from breathing radon released to air from tap water.
Arsenic a natural element that can be found in rocks and soil, water, air, and in plants and animals. It can also be released into the environment from some agricultural pesticides and industrial sources.
  • Poisoning caused by ground water that naturally contains high concentrations of arsenic.
  • Chronic exposure to arsenic is related to vitamin A deficiency, which is related to heart disease and night blindness.
  • Related to heart disease (hypertension related cardiovascular), cancer, stroke (cerebrovascular diseases), chronic lower respiratory diseases, and diabetes.
Chlorine A chemical element. Chloramine, chlorine, and chlorine dioxide are common water additives used to control microbes in municipal water systems.
  • According to the EPA, exposure to high levels of chlorine, chloramine, or chlorine dioxide could cause irritating effects to the eyes and nose, stomach discomfort or anemia.
  • Again, according to the EPA, some infants, young children, and unborn children of pregnant women who drink water containing chlorine dioxide in excess of the maximum residual disinfectant level could experience nervous system effects..
  • Some doctors have theorized that chlorine can have a negative effect on your gut flora, causing food allergies or behavioral issues.
  • Corrosive to seals, which can lead to plumbing leaks
  • Bleach smell and taste in drinking water.
