Groundwater Sustainability Plans under SGMA must work to avoid six undesirable outcomes from unsustainable pumping, which include the following EXCEPT:

Question

BlackTom AI · Accepted Answer

The question asks which item is NOT among the six undesirable outcomes that groundwater pumping under SGMA aims to avoid.
Option 1: Reduction in groundwater storage. This is a classic undesirable outcome because it directly signals depletion of available groundwater and can lead to long-term sustainability problems.
Option 2: Seawater intrusion. This is a well-known adverse effect in coastal aquifers when groundwater levels drop, allowing seawater to encroach, degrade fresh water supplies, and raise treatment costs.
Option 3: Degraded water quality. Lower groundwater levels or increased pumping can concentrate contaminants or mobilize minerals, reducing the overall quality of the aquifer water and risking human and ecological health.
Option 4: Increase hydraulic conductivity of aquifers. Hydraulic conductivity is a property of the geological material that governs how easily water moves through it. It is not an outcome caused by pumping; rather, it describes the ease of flow within the aquifer. SGMA seeks to prevent changes that lead to undesirable conditions such as those in options 1–3, but an increase in hydraulic conductivity is not listed as an undesirable outcome and is not a direct consequence of pumping management in the same way.
Therefore, the statement in option 4 does not describe one of the SGMA’s six undesirable outcomes, whereas options 1–3 do. The question asks for the EXCEPT, so option 4 is the correct choice for this question.
