“…Well 1 and well 2 (in 2013, 2014 & 2015), have a ratio higher than one (>1), clarify the dissolution of calcite, which suggest that water moves in limestone or that limestone is rich with dolomite, Equations 2 & 3. Well 3 (2013, 2014& 2015 has ratio greater than > 2, this indicates the dissolution of silicate minerals into the groundwater, Equation 1. Finally, the source of calcium in monitoring wells was the calcite, limestone and dissolution of silicate minerals (calcium leached from cement pore water).…”
