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, very hard is the largest category, covering 59 of 98 profiles with hardness data. The state median is 227 PPM, but the full indexed range is 9.6–335 PPM.
