 # Groundwater challenges and sustainable groundwater
 
-Over the past three lectures we have discussed the importance of groundwater systems, how groundwater moves (and why it can move uphill), and how we can test for and figure out the key aspects that influence groundwater flow, which includes pumping tests.
+We have discussed the importance of groundwater systems, how groundwater moves (and why it can move uphill), and how we can test for and figure out the key aspects that influence groundwater flow, which includes pumping tests.
 Together these give us a good sense of how to calculate groundwater velocity and the energy required to move groundwater.
 There are several environmental challenges that face Earth’s groundwater systems, not least of which is the fact that we are removing groundwater faster than it can {term}`recharge`.
 We can see this in global maps of groundwater depletion ({numref}`groundwater_depletion`).

 Seawater can {term}`recharge` an aquifer and contaminate it with salt water if we extract too much water near the coast. This problem will be exacerbated by sealevel rise, which will increase the {term}`hydraulic head` on the saline side.
