What are the health risks presented by the contaminated groundwater?

There are no known health risks from the groundwater. The groundwater is located over 600 feet below ground surface (ft bgs) and there is no exposure pathway to this water.

The water is not part of the potable (drinkable) water supply. The nearest drinking water wells are over 1 mile to the southeast and are screened at a much deeper (more than 1,000 feet below ground surface) level. These are City of Phoenix wells that are regularly tested for safe drinking water parameters.
