Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. In the Houston-Galveston region, land subsidence is caused by compaction of fine-grained aquifer sediments (silts and clays) geographic information system (GIS) and used for the construction of regional water-level altitude and available to store water resulting in the lowering (sinking or settling) of the land-surface. The results of this study confirm the potential for compaction in the Jasper aquifer and subsidence to occur from brackish groundwater development particularly in up-dip areas near where the Jas-per is being used for freshwater supply. Most compaction that occurs as a result of groundwater withdrawals is irreversible; even if groundwater It is the purpose of the HGSD Regulatory Plan to establish policy in the area of groundwater regulation, permits and enforcement.
