Water containing more than 20mg/L of sodium should not be used for drinking by people on severely restricted sodium diets. Water containing more than 270mg/L of sodium should not be used for drinking by people on moderately restricted sodium diets.

A low pH (acidic) can cause corrosion of household plumbing causing lead to be leached out into the drinking water from any lead solder joints, the water service line from private well, and/or plumbing fixtures containing lead. A high pH (basic) can cause slippery feel, soda taste and deposits. pH range should be 6.5 to 8.0.
