This article was published on 1/5/06 in the Honolulu Advertiser. The title is Watertable Levels are Dropping.
The article discusses evidence that the groundwater in O'ahu is decreasing in abundance and quality.
In class we discussed the groundwater system of a Hawaiian island. The largest reservoir is the basal groundwater system. Freshwater is less dense than seawater, so the basal groundwater system floats on seawater. The basal groundwater lens is thickest under the mountains and thinnest near the coast. The mountains (watershed area) is the primary recharge region. Groundwater flows from the recharge area to the discharge area, the coastline.
