They may test for total sulfur which would include all sulfur containing compounds present including sulfate. Total sulfur analyses are often misconstrued as a hydrogen sulfide test, emphasizing the need to thoroughly review any water analysis report. The presence of sulfate does not mean that hydrogen sulfide is present, and vice versa. In the water treatment world, the sulfate level is an important consideration when evaluating potential corrosion of lead solder, and the associated increased lead levels in the water.
Sulfates can form thin protective layers on lead surfaces that inhibit galvanic corrosion from chlorides. A CSMR of 0. Lead corrosion from a lead solder interface is influenced by other factors like pH and alkalinity, but the CSMR is especially important to consider when removing sulfate from water. For example, a strong base anion resin in the chloride form can be used to remove elevated levels of sulfate in water.
However, this is not generally an advisable approach to treating for high sulfates. This approach will remove sulfates, but will often create a corrosion problem because it will raise the chloride levels of the treated water, and in turn increase the CSMR.
You would install this on the inlet side of the water heating tank and add peroxide to aid in the disinfection process. If this does not work, try replacing the magnesium anode rod with an aluminum anode, or remove the system and install either an on-demand system, a plastic-lined tank, or a commercial stainless steel unit. If you are a city water customer and there is a sulfur smell to your water, the first step is to check to see if the odor is present in the water when it enters the home or building.
If there is no problem at the entry point, the problem is most likely a bacterial regrowth in the water distribution system for the building or a back flow problem in the building. The next step would be to check for back flow issues and shock-disinfect and flush all water lines.
It is possible that the level of sulfate may be elevated in well water and other private systems. If there is any odor anywhere in the water, the first step would be a shock-disinfection of the system and a pasteurization of the hot water lines. Do not boil the water; it is likely this would increase the sulfate concentration in the water although it would drive out any hydrogen sulfide gas, maybe not such a good idea inside the building.. Sulfate - For treating small quantities of water, drinking and cooking only, the typical methods are distillation or reverse osmosis.
Reverse osmosis membranes have a porosity that permits water molecules to pass through but leaves the large ions, such as sulfate, in solution. If the gas is associated with a nuisance bacteria, the oxidation process will need to include a strong oxidizer that can disinfect the water. Because problems with sulfur and hydrogen sulfide are normally complex issues, we recommend that you hire a local professional to develop a long-term solution.

Home Indoor Outdoor Services Search. This is a newly redesigned Water-Research. How Does Sulfate Become a problem? How Does Hydrogen Sulfide Become a problem? What are the Health Risks for Sulfate? What are the Standards for Sulfate? Get Tested Sulfate Like many contaminants in drinking water this anion creates a potential health issue at a level that is not easy to detect. Level 1 Observational Self-Testing Level 1 Testing is done with simple observations that an individual can make with their own senses such as sight, smell, and taste.
Notes on Level 1 Testing for Sulfate, Hydrogen Sulfide, Sulfate Reducing Bacteria, and Sulfur You will suspect a problem with sulfate if the water has a sulfur odor, black particles, or you are experiencing diarrhea.
Observations As previously mentioned, problems with hydrogen sulfide will typically be most evident by smell, but it can also be associated with other aesthetic issues, such as discolored water, premature failure of water related equipment and fixtures, and corrosion of fixtures.

Notes on Level 2 Testing for Sulfate, Hydrogen Sulfide, Sulfate Reducing Bacteria, and Sulfur Sulfate test strips are a reliable and easy way to screen your drinking water for the presence of sulfates. Tap Score Hydrogen Sulfide. Notes on Level 3 Testing for Sulfate, Hydrogen Sulfide, Sulfate Reducing Bacteria, and Sulfur If you conduct an informational water quality test, we suggest a testing package that includes trace metals, bacteria, nutrients, and sulfur compounds.
Level 4 Certified Testing. Notes on Level 4 Testing for Sulfate, Hydrogen Sulfide, Sulfate Reducing Bacteria, and Sulfur A problem with hydrogen sulfide gas may be associated with a chemical or biochemical issue with the water. Get Treatment Sulfate and Hydrogen Sulfide Several methods of removing sulfate from water are available.
If the odor is stronger in the electric water tank, we recommend the following: a. Allow the tank to stay at this level for at least 6 to 10 hours. Turn off the system and reduce the system to the normal temperature setting. Drain any discolored water and then allow the tank to refill.
It would be advisable to check the quality of the water entering the tank. Recommended Short-Term Treatments Amazon. Test Strips, Hydrogen Sulfide in Water. Tap Score. Hydrogen Sulfide.

A little larger units, normally installed under the sink, will produce 19 to RO units generally produce only 3.
The remaining water is rejected. Distillation is a water treatment system in which water is boiled, and then the steam is cooled until it condenses into a separate container.
The dissolved substances, such as sulfate, remain in the boiling pot. Distillation units need about four hours to produce 3. Ion Exchange is the most known method of eliminating big quantities of sulfate from water for public, livestock, and commercial supplies, but is not generally used for individual household water treatment. It is a process where one element or chemical is replaced for another.
Many people are familiar with water softening, a conventional type of ion exchange system. This system works by passing "hard" water - water with calcium and magnesium - through a tank filled with a special resin saturated with sodium ions. The minerals that cause the hardness stick to the resin, and the sodium dissolves in the water.
Ion exchange systems for removal of sulfate use a different type of resin, but they work in an analogous manner. Sulfate ions in the water switch places with other ions which are on the resin, usually chloride.
When the resin is full with sulfate, it must be "regenerated" with a salt solution. Water softeners do not remove sulfate, and sulfate removal systems do not remove hardness, although some commercial units contain both resins and can remove both hardness and sulfate.
If both a water softener and a sulfate elimination system are used, the water softener is generally placed before the sulfate elimination system.
Any water treatment system needs adequate operation and maintenance to ensure that it functions properly over time. It is important to follow the recommendations of the manufacturer for the maintenance of the water treatment system.
