What is groundwater recharge and how is it changing here in New Hampshire?
19:36
The second one, we're moving away from groundwater rise due to sea level rise, and we're thinking about groundwater recharge.
19:43
And groundwater recharge is you have precipitation or snowfall and snow melt that seeps into the ground and recharges the aquifer.
19:51
And when we talk about recharging the aquifer, we mean that the water is moving all the way down through the unsaturated soils to that water table.
19:59
And that's important because, you know, many people get their drinking water supplies from groundwater, and many communities in coastal New Hampshire get their public water supplies out of the ground.
20:09
So recharge is important, and knowing how that is changing going into the future is also important.
20:15
So what we found is that our seasons are changing somewhat.
21:02
How does this heavier rainfall in the winter and spring impact groundwater recharge?
