Understanding Nevada
Why local comparisons matter here
Nevada communities rely on basin-fill groundwater, mountain recharge, and—in the Las Vegas area—Colorado River water from Lake Mead.
In this index, moderately hard is the largest category, covering 39 of 77 profiles with hardness data. The state median is 66 PPM, but the full indexed range is 39–407 PPM.
