The scientists studied the Caposele aquifer using a computer model to understand how groundwater flows in the area. They looked at different thicknesses of the aquifer's water-saturated zone and found a link between water pressure, zone thickness, and how easily water moves through the aquifer. By analyzing the data, they discovered that groundwater takes longer to travel through a thicker zone and less time through a thinner zone. They divided the aquifer into different areas that affect how water moves in and out, and they also identified where water flows upward near the spring.
