This chart was on the Palomar Mountain Spring Water web site. Look at the figures for the Total Dissolved Solids (TDS) in the various samples. These represent the dissolved contaminants in the water, so generally the lower the number the better. If these figures are true, the only water listed here that I would drink on a regular basis would be the Sparkletts water. It appears that Palomar's approach is to decide what minerals you need in your water. But not all minerals are good for all people. I prefer to know that my water is as pure as reasonably possible and regulate my own mineral intake by my choice of food and vitamin supplements.
