The area of the springs, on the Ota River, was once a leisure area for the local population, including the local bathing area in the summer. This site remained natural for a long time after the EPAL was installed, but at a certain point, the intensification of agriculture with the use of chemical fertilizers and pesticides, intensive livestock farming, and urban sewage made the flow from upstream a polluting threat to EPAL's water intakes, and EPAL paved several dozen meters of the river course near the site where it is installed with reinforced concrete.

The karst landscape of Montejunto constitutes the extreme southwest of the Estremenho Limestone Massif. Deep valleys, lakes, gravel pits and lapiás are some of the formations found here, testimonies of various geological eras. Water has been the protagonist in erosion phenomena over time. Several deposits of gravel pits result from the cracking of the outcrops caused by the expansion of the water which, when freezing, breaks the rock into small parts.
