In most cases of excess nitrate concentrations in water supplies, the primary source is surface runoff from agricultural or landscaped areas which have received excess nitrate fertilizer. These levels of nitrate can also lead to algae blooms, and when nutrients become limiting (such as potassium, phosphate or nitrate) then eutrophication can occur. As well as leading to water anoxia, these blooms may cause other changes to ecosystem function, favoring some groups of organisms over others. Consequently, as nitrates form a component of total dissolved solids, they are widely used as an indicator of water quality.

Nitrates are also a by-product of septic systems. Specifically, they are a naturally occurring chemical that is left after the break down or decomposition of animal or human waste. Water quality may also be affected through ground water resources that have a high number of septic systems in a watershed. Nitrate in groundwater originates primarily from fertilizers, septic systems, and manure storage or spreading operations. Fertilizer nitrogen that is not taken up by plants, volatilized, or carried away by surface runoff leaches to the groundwater in the form of nitrate. This not only makes the nitrogen unavailable to crops, but also can elevate the concentration in groundwater above the levels acceptable for drinking water quality. Nitrogen from manure similarly can be lost from fields, barnyards, or storage locations. Septic systems also can elevate groundwater nitrate concentrations because they remove only half of the nitrogen in wastewater, leaving the remaining half to percolate to groundwater.

How is it used?
Nitrates are used mostly for agriculture. Nitrates such as potassium nitrate (saltpeter) and ammonium nitrate are an important source of nitrogen in fertilizers. These nitrates must be used quickly by plants because they are easily lost through leaching or densification by bacteria. Nitrate pollution has become an environmental issue in rivers and oceans.

What are the health effects?
Methemoglobinemia is the most significant health problem associated with nitrate in drinking water. Blood contains an iron-based compound called hemoglobin, which carries oxygen. When nitrate is present, hemoglobin can be converted to methemoglobin, which cannot carry oxygen. In the blood of adults, enzymes continually convert methemoglobin back to hemoglobin, and methemoglobin levels normally do not exceed 1 percent. Newborn infants have lower levels of these enzymes, and their methemoglobin level is usually 1 to 2 percent. Anything above that level is considered methemoglobinemia.




Is there any harm from drinking and bathing in contaminated water?




Congress passed the federal Safe Drinking Water Act in 1974. The U S. Environmental Protection Agency was given responsibility for setting drinking water standards for all the states, and each state became responsible for enforcing these standards.




Because potential health risks are often unknown or hard to predict, many drinking water standards are set at some fraction of the level of "no-observed adverse-health effects." In general, the greater the uncertainty about potential health effects, the greater the margin of safety built into the standard.




The ionization process will concentrate nitrates and send them out the acidic hose. However, to remove nitrates before reaching the ionizer, pre-filtration is recommended.

Hydrogen Sulfide
As a chemical compound, H2S, is a colorless gas that has a very disagreeable odor, much like that of rotten eggs and slightly soluble in water. Dissolved in water, it forms a very weak dibasic acid that is sometimes called hydrosulfuric acid. Hydrogen sulfide is flammable; in an excess of air it burns to form sulfur dioxide and water, but if not enough oxygen is present - it forms elemental sulfur and water.


Hydrogen sulfide is found naturally in volcanic gases and in some mineral waters. It is often formed during decay of animal matter. It is a part of many unrefined carbonaceous fuels, e.g., natural gas, crude oil, and coal; it is obtained as a byproduct of refining such fuels. It may be made by reacting hydrogen gas with molten sulfur or with sulfur vapors, or by treating a metal sulfide (e.g., ferrous sulfide, FeS) with an acid. Hydrogen sulfide reacts with most metal ions to form sulfides; the sulfides of some metals are insoluble in water and have characteristic colors that help to identify the metal during chemical analysis.

How is it used?
Natural gas contains up to several percent H2S(g) and as such are called sour gas wells from their offensive stench.  Volcanoes also discharge hydrogen sulfide.  Anaerobic decay aided by bacteria produces hydrogen sulfide, which in turn, produces sulfur.  This process accounts for much of the native sulfur found in nature. Commercially hydrogen sulfide is obtained from "sour gas" natural gas wells. Hydrogen sulfide has few important commercial uses.  However, it is used to produce sulfur which is one of the most commercially important elements. Exposure in a residential setting can come from nearby industrial and agricultural sources, oil and gas development, and wastewater treatment plants, all generally regulated sources. However, exposure to hydrogen sulfide from contaminated drinking water is an exposure route often not covered by regulation, especially rural drinking water supplies from groundwater. Hydrogen sulfide gas also occurs naturally in some groundwater. It is formed from decomposing underground deposits of organic matter such as decaying plant material. It is found in deep or shallow wells and also can enter surface water through springs, although it quickly escapes to the atmosphere. Hydrogen sulfide often is present in wells drilled in shale or sandstone, or near coal or peat deposits.

What are the health effects?
Immediate symptoms from the gas may include dizziness and an upset stomach; lengthy expose may led to loss of consciousness and/or death.


Is there any harm from drinking and bathing in contaminated water?


Although many impurities are regulated by Primary or Secondary Drinking Water Standards set by the EPA, hydrogen sulfide is not regulated. A concentration high enough to be a drinking water health hazard also makes the water unpalatable.


The odor of water with as little as 0.5 ppm of hydrogen sulfide concentration is detectable by most people. Concentrations less than 1 ppm give the water a "musty" or "swampy" odor. A 1-2 ppm hydrogen sulfide concentration gives water a "rotten egg" odor and makes the water very corrosive to plumbing.

Iron is one of the earth's most plentiful resources, making up at least five percent of the earth's crust. Rainfall seeping through the soil dissolves iron in the earth's surface and carries it into almost every kind of natural water supply, including well water.

Iron is generally divided into two main categories:

1) Soluble or
"Clear water" iron, is the most common form and the one that creates the most complaints by water users. This type of iron is identified after you've poured a glass, of cold clear water. If allowed to stand for a few minutes, reddish brown particles will appear in the glass and eventually settle to the bottom.

2) Insoluble
When insoluble iron, or "red water" iron is poured into a glass, it appears rusty or has a red or yellow color. Although less common in water wells, insoluble iron can create serious taste and appearance problems for the water user.


Because iron combines with different naturally occurring acids, it may also exist as an organic complex. A combination of acid and iron, or organic iron, can be found in shallow wells and surface water. Although this kind of iron can be colorless, it is usually yellow or brown.


Finally, when iron exists along with certain kinds of bacteria, problems can become even worse. Iron bacteria consume iron to survive and leave a reddish brown or yellow slime that can clog plumbing and cause an offensive odor. You may notice this slime or sludge in your toilet tank when you remove the lid.

What are the effects?

Iron is not hazardous to health, but it is considered a secondary or aesthetic contaminant. Essential for good health, iron helps transport oxygen in the blood. Most tap water in the United States supplies approximately 5 percent of the dietary requirement for iron. The maximum contaminant level for Iron is .3 milligram per liter.

Taste and Food
Dissolved ferrous iron gives water a disagreeable taste. When the iron combines with tea, coffee and other beverages, it produces an inky, black appearance and a harsh, unacceptable taste. Vegetables cooked in water containing excessive iron turn dark and look unappealing.

Stains and Deposits
Concentrations of iron as low as 0.3 mg/l will leave reddish brown stains on fixtures, tableware and laundry that are very hard to remove. When these deposits break loose from water piping, rusty water will flow through the faucet.

How do I remove Hydrogen Sulfide and  Iron from my drinking water?


This filter includes a compound called KDF that has long been used in water treatment industry for the removal of Iron, Manganese, and Hydrogen Sulfides. This filter also utilizes carbon for the reduction of Chlorine, Taste, and Odor. This filter is intended for use outside of water ionizer machines.
