Typical Landuse:

Water is removed from subsurface water source.

Not Applicable

Well development will provide a dependable supply of water allowing more concentrated management.

Not Applicable

The action involves production rather than distribution of available water.

Not Applicable

Where well flows are used for irrigation, contaminants can be leached below the root zone.

In coastal areas pumping fresh groundwater may allow the intrusion of saltwater.

Use of wells to irrigate previously non irrigated land will increase the likelihood of soluble and sediment-attached contaminants 

moving of-site. Probable less contaminants on grazing lands
