If you do have elevated levels of barium in your water, there are treatment technologies available now that can reduce or even completely remove it. Although barite is non-toxic, when it comes in contact with deep water brines existing below the Earths surface that are high in naturally occurring chloride, it converts to barium chloride, which is highly toxic. Barium may cause gastrointestinal issues and can affect the brain and nervous system causing brain swelling, cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis. State guidelines for California are 1 mg/L or 1000 ppb, and for Arizona 1.5 mg/L or 1500 ppb. Strontium and barium have reactivities similar to lithium in Group 1 of the Periodic Table.
