Common Water Problems

Well Water Problems

Your home's water problems in Aledo, Weatherford, Fort Worth, Benbrook or other surrounding city can be easily remedied with water purification services by the exeprts at Oliver's Pure Water. Such problems include:

Hydrogen Sulphide (Rotten Egg Smell)

Hydrogen Sulphide is the gas that you're smelling. It is formed a few different ways:

  • 1. Decay of organic matter from the bottom of lakes, rivers, streams, ponds, etc.
  • 2. Sulfur containing minerals in soil and rock formations underground.
  • 3. Sulphate reducing bacteria converts elemental sulfur into Hydrogen Sulphide Gas.
  • 4. The Magnesium anode rod inside hot water heater reactes with sulfates in water.

*If you have Sulfate Reducing Bacteria, Air Injection Systems Will Not Work. The bacteria will feed on "oxygen" just as they feed on sulfur, creating a slime inside the off-gas tank that will ruin the filter media and stop working after a year or so.

*Chlorine systems require too much contact time. Who wants to put a "big black storage tank" in the yard? On top of that the water usually doesn't taste very good. We provide water purification for sulfate water problems in Aledo, Weatherford, Fort Worth, Benbrook and other nearby cities.

Iron (Red Stain)

Iron is mainly found in two forms: either soluble ferrous iron or insoluble ferric iron. Water containing soluble ferrous iron is clear and colorless until it is oxidized, sometimes in the pressure tank, or exposed to the atmosphere at which time it becomes insoluble ferric iron. Ferric iron turns the water cloudy and a reddish brown substance will form causing stains.

*When iron exists along with certain types of Bacteria problems can become worse. The bacteria feed on the iron leaving behind a reddish brown or yellow slime that can clog regular iron filters and produce smell.


Total Coliform Bacteria are a group of bacteria that any local lab is going to test for. They are kind of like "indicator" bacteria to see if conditions in the well are too suitable for other harmful bacteria. If you have coliform bacteria, this does not mean the water is unsafe. These bacteria are just a nuesance, loving your water heater, creating a slime on pipes and the inside of tanks, and producing a foul smell. The bacteria to look for are fecal colifrm, bacteria that come from warm blooded animal waste, and e-coli which comes from human waste.

City Water Problems

At Oliver's Pure Water, we specialize in water purification for city water problems in Weatherford, Aledo, Fort Worth and surrounding areas that can include:

Calcium (White Spots)

85% of America's water is hard, contaminated with dissolved minerals like calcium, magnesium, scale and limestone that can dry out your skin, age your plumbing, and ruin appliances like dishwashers, coffee makers and water heaters. These hard water minerals form deposits on the inside of your plumbing, white spots on dishes and a film on shower doors.

* Spot Free Rinse cycles at the car wash use water softeners to remove calcium from rinse water.


Yes chlorine is in the water problems section, not the solution section. City water, municipal water or a small water provider (they are the worst) dump chlorine in the water like its going out of style.....which it is actually. Chlorine in drinking water should be removed. We have tested some city water that had over 6ppm chlorine, this is double what a swimming pool should have. Why are we so comfortable with chlorine? I do not like the burn in my eyes when I swim and I detest the redness in my childrens eyes when they swim, yet some of the smaller water providers have more chlorine in the water than a swimming pool is supposed to have. I have tested many local city water sources with a chlorine residual of over 4 ppm. ( a pool should be between 1 ppm to 3ppm max.

T.D.S (Total Dissolved Solids)

Refers to the total amount of all inorganic and organic substances, including minerals, salts, metals, cations or anions. While T.D.S. is not considered a primary pollutant, high T.D.S levels typically indicate hardness. If "0" T.D.S. is desired, Reverse Osmosis is needed. Reverse Osmosis systems are the only method to remove sodium. Reverse Osmosis is the exact same process bottled water goes through.

Bad Taste and Odor

This is likely due to Chlorine and Chlorine Byproducts. In some cases where the city pulls water from a lake it may get worse when the lake turns. Some tastes and smells like to hide inside hard water minerals.

Sulfate which is a combination of sulfur and oxygen (SO4) exists as a dissolved salt in the water. As such it is colorless and odorless. It is not to be confused with the gas in the water that causes a rotten egg odor. This is a combination of Hydrogen and Sulfur (H2S). Removal technology is totally different for the two forms of sulfur. Sulfate will react with aluminum and magnesium( what anode rods inside water heaters are made of) and produce that nasty smell in the hot water only.

Sulfates: The US Primary Drinking Water Regulations list safe levels of sulfates at 500 ppm (mg/l) in drinking water and Secondary Drinking Water Regulations for sulfates at 250 ppm (mg/l). At this level or above, sulfates can cause diarrhea and resulting dehydration. This condition is most severe in infants, the elderly, and people with other illnesses. Also, high sulfates cause fluid and resulting weight loss in all animals. Sulfates can be reduced by approximately 80% with under counter household R.O. units. About 95% is removed by high pressure commercial R.O. units. For virtually 100% removal, special softeners utilizing resins that are selective to sulfates can be used. With these units, the sulfates are exchanged for chlorides. There are no restrictions on or known harmful effects associated with chlorides in the water. Sulfate content up to 2,500 ppm (mg/l) can easily be handled in this manner.

What Causes the Rotten Egg Smell in my Well Water?

Is it Harmful?

The rotten egg (sulfur) smell in your well water is technically called Hydrogen Sulfide Gas (H2S). Hydrogen sulfide gas can result from a number of different sources.

  • It can occur naturally in groundwater.
  • It can be produced by "sulfur bacteria" in the groundwater, in the well, or in the water distribution system.
  • It can be produced also by sulfur bacteria or chemical reactions inside water heaters.
  • In rare instances, it can result from pollution.

The source of the gas is important when considering treatment options.

Are sulfur bacteria or hydrogen sulfide harmful?

In most cases, the rotten egg smell does not relate to the sanitary quality of the water. However, in rare instances the gas may result from sewage or other pollution. It is a good idea to have the well tested for the standard sanitary tests of coliform bacteria and nitrate.

Sulfur bacteria are not harmful, but hydrogen sulfide gas in the air can be hazardous at high levels.

Are there other problems associated with sulfur bacteria or hydrogen sulfide?

Yes. Sulfur bacteria produce a slime and can promote the growth of other bacteria, such as iron bacteria. The slime can clog wells, plumbing, and irrigation systems. Bacterial slime may be white, grey, black, or reddish brown if associated with iron bacteria. Hydrogen sulfide gas in water can cause black stains on silverware and plumbing fixtures. It can also corrode pipes and other metal components of the water distribution system.

What causes hydrogen sulfide gas to form in groundwater?

Decay of organic matter such as vegetation, or chemical reactions with some sulfur-containing minerals in the soil and rock, may naturally create hydrogen sulfide gas in groundwater. As groundwater moves through soil and rock formations containing minerals of sulfate, some of these minerals dissolve in the water. A unique group of bacteria, called "sulfur bacteria" or "sulfate-reducing bacteria" can change sulfate and other sulfur containing compounds, including natural organic materials, to hydrogen sulfide gas.

How is hydrogen sulfide gas produced in a water heater?

A water heater can provide an ideal environment for the conversion of sulfate to hydrogen sulfide gas. The water heater can produce hydrogen sulfide gas in two ways - creating a warm environment where sulfur bacteria can live, and sustaining a reaction between sulfate in the water and the water heater anode. A water heater usually contains a metal rod called an "anode," which is installed to reduce corrosion of the water heater tank. The anode is usually made of magnesium metal, which can supply electrons that aid in the conversion of sulfate to hydrogen sulfide gas. The anode is 1/2 to 3/4 inches in diameter and 30 to 40 inches long. It should be removed as long as you soften the water first.

How can I find the source of a hydrogen sulfide problem, and what can I do to eliminate it?

The odor of hydrogen sulfide gas can be detected in water at a very low level. ( .02 ppm)Smell the water coming out of the hot and cold water faucets. Determine which faucets have the odor. The "rotten egg" smell will often be more noticeable from the hot water because more of the gas is vaporized. Your sense of smell becomes dulled quickly, so the best time to check is after you have been away from your home for a few hours. If the smell is only from the hot water faucet the problem is likely to be in the water heater. If the smell is in both the hot and cold faucets then the problem is likely caused from hydrogen sulfide or sulfur bacteria in the well.

What if the smell is just in my hot water?

(Unless you are very familiar with the operation and maintenance of the water heater, you should contact a water system professional, such as a plumber, to do any work on your water heater.)

If the smell is just coming from your hot water, and not at all from your cold water, then replacing or removing the magnesium anode rod in your hot water tank may be the solution. Many water heaters have a magnesium anode, which is attached to a plug located on top of the water heater. It can be removed by turning off the water, releasing the pressure from the water heater, and unscrewing the plug. Be sure to plug the hole. However The anode rods pupose is to provide corrosion protection, you will have to install a water softener,if you have a water softener or already have soft water the anode rod is not needed. Disinfect and flush the water heater with a chlorine bleach solution: Chlorination can kill sulfur bacteria, if done properly. If all bacteria are not destroyed by chlorination, the problem may return within a few weeks. Kill the bacteria with heat: Increase the water heater temperature to 160 degrees Fahrenheit (71 degrees Celsius) for several hours. This will destroy the sulfur bacteria. Flushing to remove the dead bacteria after treatment should control the odor problem.

CAUTION: Increasing the water heater temperature can be dangerous. Before proceeding, consult with the manufacturer or dealer regarding an operable pressure relief valve and for other recommendations. Be sure to lower the thermostat setting and make certain the water temperature is reduced following treatment to prevent injury from scalding hot water and to avoid high energy costs.
