  Barium sulfate
Barium sulfate has such a low solubility in water that it is undetectable in solution without the use of elaborate equipment or methods.
If two soluble ionic compounds, such as barium chloride and ammonium sulfate, are mixed, the ions rearrange to form a precipitate of barium sulfate, leaving ammonium and chloride ions in solution.
Before the attempt is made to make the barium sulfate precipitate using perfect quantities of reagents, and then to test whether the mixture was indeed perfect, some planning is necessary.

Barium and barium compounds have been found in at least 798 of the 1,662 current or former NPL sites; however, the total number of NPL sites evaluated for this substance is not known.
The barium in these compounds that is dissolved in water quickly combines with sulfate or carbonate that are naturally found in water and become the longer lasting forms (barium sulfate and barium carbonate).
Barium sulfate and barium carbonate are the barium compounds most commonly found in the soil and water.

 Method of inhibiting barium sulfate and strontium sulfate scale at low pH - Patent 5486294
This aqueous acid stream is susceptible to the formation of barium sulfate and strontium sulfate scales due to the SO.sub.4.sup.- ion in the dilute acidic stream.
These sulfate scales, in addition to fouling the resin, have been linked to naturally occurring radioactive materials which are present in low levels in the produced waters.
Studies were undertaken to determine the relative efficacy of PESA and phosphonates for barium/strontium sulfate inhibition at low pH such as encountered during regeneration of a water softener resin in a produced water oilfield system.
