What is sulfate in drinking water?

Sulfate is one of the major dissolved components of rain. High concentrations of sulfate in the water we drink can have a laxative effect when combined with calcium and magnesium, the two most common constituents of hardness. Bacteria, which attack and reduce sulfates, form hydrogen sulfide gas (H2S).

What are some possible sources of the sulfate?

As water moves through soil and rock formations that contain sulfate minerals, some of the sulfate dissolves into the groundwater. Minerals that contain sulfate include magnesium sulfate (Epsom salt), sodium sulfate (Glauber’s salt), and calcium sulfate ( gypsum ).

How much sulfate is safe in water?

Sulfate in drinking water currently has a secondary maximum contaminant level (SMCL) of 250 milligrams per liter (mg/L), based on aesthetic effects (i.e., taste and odor). This regulation is not a Federally enforceable standard, but is provided as a guideline for States and public water systems.

Hydrogen sulfide produces an offensive “rotten egg” odor and taste in the water, especially when the water is heated.

How do you test water for sulfates?

The Sulfate Vacu-vials® test kit employs the turbidimetric method. Sulfate ion reacts with barium chloride in an acidic solution to form a suspension of barium sulfate crystals of uniform size. The resulting turbidity is proportional to the sulfate concentration of the sample.

Why are sulfates important?

Sulfates are chemicals used as cleansing agents. They’re found in household cleaners, detergents, and even shampoo. Two main types of sulfates are used in shampoo: sodium lauryl sulfate and sodium laureth sulfate. The purpose of these sulfates is to create a lathering effect to remove oil and dirt from your hair.
