Valle de Pan de Azúcar Aquifer (Spanish; Castilian: acuífero del Valle de Pan de Azúcar) is an aquifer located in an agricultural zone in the semi-arid Coquimbo Region of northern Chile.[1] Since 2003 the water authority Dirección General de Aguas has restricted the inscription of new wells tapping the aquifer.[1] Given its proximity to the Pacific Ocean part of the aquifer has been subject to saline intrusion.[1] A series of artificial groundwater recharge wells have been constructed in the 2020s as part of a joint project between the Netherlands and the Government of Coquimbo Region.[2]
