 Well Water quality can vary from  well to well – even season to season.  For that reason we have provided a list of the most common well water problems and  treatment methods that our customers throughout the USA have contacted us about. 

Water Hardness: (what is hard water ?)

Hardness is a result of the amount of dissolved calcium and magnesium in the water. Hard water does not lather soap well and can form a hard scale when heated.

Hard water can dry out skin and makes hair brittle. It causes soap scum in tubs and showers and spots on faucets, fixtures and dishes. It also causes scaling in appliances such as washing machines, diswashers and water heaters, which can result in high operation costs and premature replacement.

Hardness is measured in parts per million (or the equivalent mg/L) or in grains per gallon (gpg). Note: if the water analysis is given in ppm as CaCO3 then 1 gpg = 17.1 ppm. There is no established limit for the acceptable level of hardness in water, but it is generally considered to become problematic at around 3 gpg.

Levels of hardness are referred to as follows:

Soft Water: 0 - 1 grains per gallon (gpg)
Slightly Hard Water: 1 - 4 grains per gallon (gpg)
Moderately Hard Water: 4 - 7 grains per gallon (gpg)
Hard Water: 7 - 10 grains per gallon (gpg)
Very Hard Water: Over 10 grains per gallon (gpg)

Iron: (what is well water iron ?)

The presence of Iron is a very common water quality problem, particularly in water from deep wells. Water containing even a significant quantity of iron may appear clear when drawn, but will rapidly turn red upon exposure to air. This process is called oxidation, and involves the conversion of ferrous (dissolved - clear water iron) iron, which is highly soluble, to ferric (precipitated - red water iron) iron, which is largely insoluble. The ferric iron then causes red/brown or orange staining on clothes, fixtures, etc. Iron water also has an unpleasant metallic bitter taste.

Iron concentration is measured in ppm or mg/l (milligrams per liter, where 1 ppm = 1 mg/l). Staining usually becomes a problem at concentrations greater than 0.3 ppm. Iron: EPA secondary drinking water standard is 0.3mg/l

Iron Bacteria (what is iron bacteria ?)
(Galion Ella and Cremothrix) Iron bacteria live by obtaining energy through the oxidation of ferrous iron to ferric iron and utilize the resulting CO2 to create organic molecules for their existence. Growths of these bacteria result in a gelatinous material, which can clog pipes, produce a sulfur odor and cause a foul taste. This material often forms in the tanks of toilets and will produce a "rainbow" slick on the surface. The most common non-pathogenic bacteria found in water, is iron bacteria. Iron bacteria can be readily identified by the red, feathery floc which forms overnight at the bottom of a sample bottle containing iron and iron bacteria.

Colloidal Iron (what is colloidal iron ?)

Very small particles of oxidized iron suspended in the water is called Colloidal iron. In this case the particles are extremely small, (less than 0.1 micron). Typically, they are combinations of iron and other substances, bound tightly together. Like colloids they do not settle out and can't be removed by ordinary filtration. Frequently, colloidal iron is mistaken in appearance for color rather than turbidity. Colloidal iron looks more like a colored water because the particles are so small that they cannot be seen. When water comes in contact with iron-bearing rock in the presence of decaying vegetation, conditions for forming this kind of iron exist. Colloidal iron may be present in shallow wells or surface water supplies. It is seldom found in deep well supplies. Like other forms of iron, colloidal iron causes reddish-brown stains on laundry, plumbing fixtures, and cooking utensils. When iron water is used in tea, coffee or whisky, the beverage turns unappetizingly black. Iron water has an unpleasant metallic taste.

Manganese: (what is well water manganese ?)

Manganese is seldom found alone in a water supply, is usually accompanied by iron. Concentrations as low as 0.05 part per million of manganese will produce dark brown or black staining. Fabrics washed in manganese-bearing waters are almost invariably stained. Deposits collect in plumbing, and tap water frequently contains a black sediment and turbidity. Manganese bacteria often causes clogging of pipes.  Manganese: EPA secondary drinking water standard is 0.05mg/l

Low pH: (what is acidic water ?)

Water which contains excess acidity tends to act aggressively towards plumbing and fixtures, causing corrosion and staining (i.e.-blue green stains on fixtures from copper pipes). Relative acidity/alkalinity is measured on the pH scale, ranging from 0- 1 4, where 7 is neutral, numbers lower than 7 are progressively more acidic, and numbers higher than seven are increasingly alkaline (basic). The pH value refers not to the quantity of acidity, but rather to the relative acidity/alkalinity of a particular sample. Acidic PH levels can cause heavy metal (lead & copper) leaching, causing plumbing damage, pin holes in copper pipes and fixtures. This can lead to an expensive problem in your homes plumbing system. pH: EPA secondary drinking water standard pH acceptable range for water is 6.5-8.5

Hydrogen Sulfide (H2S) “Sulfur Odor” (what is hydrogen sulfide gas ?)

Hydrogen Sulfide is a gas which smells strongly like rotten eggs. It results from the decay of organic matter with organic sulfur and the presence of certain types of bacteria. Even very low concentrations are offensive as well as highly corrosive (silver tarnishes almost immediately upon contact with H2S). hydrogen sulfide can add to the corrosion of metal plumbing materials. It will attack iron, steel, copper, and galvanized plumbing, producing a black color in the water. In combination with dissolved iron, hydrogen sulfide can produce black stains in plumbing fixtures and laundry. A black deposit may also collect in piping and on fixtures. An official limit has not been established for hydrogen sulfide in drinking water, a recommended limit of 0.05ppm (mg/1) has been proposed.

Nitrate: (what are nitrates?)

Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate that occurs in drinking water is the result of contamination of ground water supplies by septic systems, feed lots, and agricultural fertilizers. Nitrate is reduced to nitrite in the body. The EPA safe drinking water limits of below 10ppm for Nitrate/Nitrite and below 1ppm for Nitrite

Nitrites are not usually found in drinking water supplies at concentrations above 1 or 2 mg/l (ppm). Nitrates are reduced to nitrites in the saliva of the mouth and upper GI tract. This occurs to a much greater degree in infants than in adults, because of the higher alkaline conditions in their GI tract. The nitrite then oxidizes hemoglobin in the blood stream to methemoglobin, thus limiting the ability of the blood to carry oxygen throughout the body. Anoxia (an insufficiency of oxygen) and death can occur. The US EPA has established the MCL (maximum contaminant level) for nitrite at 1 mg/l.  


Tannins (humic acid) are found in waters which have passed through large quantities of decaying vegetation. Tannins can cause yellow water and yellow staining on fabrics and fixtures. Tannins measuring 0.5 PPM or higher may cause staining and/or interference with various water treatment processes.

Sulfate (SO4) occurs in almost all natural water. Most sulfate compounds originate from the oxidation of sulfite ores, the presence of shales, and the existence of industrial wastes. Sulfate is one of the major dissolved constituents in rain. High concentrations of sulfate in drinking water causes a laxative effect when combined with calcium and magnesium, the two most common components of hardness. Bacteria which attack and reduce sulfates, causes hydrogen sulfide gas (H2S) to form. Sulfate has a suggested level of 250 mg/l in the Secondary Drinking Water Standards published by the US EPA.

Sodium: Salty Drinking Water 

Sodium (Na) is a major component in drinking water. All water supplies contain some sodium  The higher the sodium content of water, the more corrosive the water becomes. A major Source of sodium in natural waters is from the weathering of feldspars, evaporates and clay. The amount of sodium in water is only a health concern when the sodium level is high or when the person's ability to handle sodium decreases. However, as the amount of sodium in water increases, or as a person's tolerance to sodium decreases, the need to be concerned about the sodium in drinking water increases. The Environmental Protection Agency suggests 20 mg or less of sodium per liter as the amount of sodium to strive for in drlnking water. The natural sodium content of water, however, varies from 0 to over 500 mg per liter (a liter is about one quart), averaging 17 mg per liter.

Total Dissolved Solids: (what are total dissolved solids ?)

Total Dissolved Solids  (TDS) - on conductivity test for dissolved materials in drinking water. TDS comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and some small amounts of organic matter that are dissolve in water. TDS in drinking water originates from natural sources, sewage, urban run-off, industrial wastewater, and chemicals used in the water treatment process and the nature of the piping or hardware used to convey the water, i.e., the plumbing. In the United States, elevated TDS has been due to natural environmental features such as: mineral springs, carbonate deposits, salt deposits, and sea water intrusion, but other sources can include: salts used for road de-icing, anti-skid materials, drinking water treatment chemicals, storm water and agricultural runoff, an point/non-point wastewater discharges. High levels of total dissolved solids can adversely industrial applications requiring the use of water such as cooling tower operations, boiler feed water, food and beverage industries, and electronics manufacturers. High levels of chloride and sulfate will accelerate corrosion of metals. The US EPA has a suggested level of 500 mg/l listed in the Secondary Drinking Water Standards.

Turbidity & Color:

Visual haziness in water. Discolored water may be caused by organic compounds or metallic ions. Turbidity has no health effect, but it can interfere with disinfectants and provide a medium for bacteria to grow. EPA standard level 5 NTU.

Commercial Sediment & Sand Water Filters: RDWS-NS Sediment Turbidity Water Filters



An element that occurs naturally in water from erosion of natural deposits. It is also found in some fertilizers and as a by-product of aluminum factories.. Fluoride can promote strong teeth. However, fluoride may cause bone disease and contribute to mottled teeth in children. The MCL established for drinking water by the US EPA is 4 mg/l.

Bacteria - E-Coli / Coliform:  (what is coliform bacteria ?)

Source - Bacteria are tiny organisms occurring naturally in water. Not all types of bacteria are harmful. Many organisms found in water are of no health concern since they do not cause disease. Biological contamination may be separated into two groups: (1) pathogenic (disease causing) and
(2) non-pathogenic (not disease causing). Pathogenic bacteria cause illnesses such as typhoid fever, dysentery, gastroenteritis, infectious hepatitis, and cholera. All water supplies should be tested for biological content prior to use and consumption. E.Coli (Escherichia Coli) is the coliform bacterial organism which is looked for when testing the water. This organism is found in the intestines and fecal matter of humans and animals. If E.Coli is found in a water supply along with high nitrate and chloride levels, it usually indicates that waste has contaminated the supply from a septic system or sewage dumping, and has entered by way of runoff, a fractured well casing, or broken lines. If coliform bacteria is present, it is an indication that disease causing bacteria may also be present. Four or fewer colonies / 100 ml of coliforms, in the absence of high nitrates and chlorides, implies that surface water is entering the water system. If pathogenic bacteria is suspected, a sample of water should be submitted to the Board of Health or US EPA for bacteriological testing and recommendations.  (what is e-coli bacteria ?)

National Primary Drinking Water Regulations

National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water. Visit the list of regulated contaminants with links for more details @

In addition, EPA has established National Secondary Drinking Water Regulations that set non-mandatory water quality standards for 15 contaminants. EPA does not enforce these "secondary maximum contaminant levels" or "SMCLs." They are established only as guidelines to assist public water systems in managing their drinking water for aesthetic considerations, such as taste, color and odor. These contaminants are not considered to present a risk to human health at the SMCL.
