TDS limit for potable water in Chile is 1500 mg/L. This decision is based on WHO standard (no evidence of human effects because its ingestion) and economical consideration. Water tariff determination allows self-financing of utilities operators (investment and operational costs).
There's not an acceptable level for raw water. It depends of its use, as wrote Joseph & others. Regards.
