The plains and valleys are formed by the deposition of Indus and its tributaries containing unconfined aquifers. In Punjab major cities including Faisalabad, Multan, Sargodha, and Lahore contain deteriorated brackish groundwater while river proximate places have better groundwater reserves.

First, the Department determines whether a well produces water from a confined aquifer or from an unconfined aquifer. (146) The Department presumes that "[a]ll wells located a horizontal distance less than one-fourth mile from a surface water source that produce water from an unconfined aquifer shall be assumed to be hydraulically connected to the surface water source, unless the applicant or appropriator provides satisfactory information or demonstration to the contrary" and conducts additional analysis for wells farther from an unconfined aquifer.

In contrast, in low yielding aquifers, such as overburdens or unconfined aquifers, dug/bored wells often are more advantageous than drilled wells.

Simultaneous influence of geology and system design on drinking water quality in private systems

Groundwater samples from the unconfined aquifer (during autumn season with 19[degrees]C of average temperature) were collected from rural wells, including windmills and domestic wells with electric pumps.

The flood gravels that filled the glacial trench in northern Idaho and the Spokane valley have been partially filled with water creating an unconfined aquifer. This ground water is the potable water supply for more than 500,000 people in the Coeur d'Alene/Post Falls/Spokane Valley/Spokane metropolitan area.
