Title: Groundwater protection incorporated into land use planning: A study from Cebu City, the Philippines.
Abstract: Municipal water suppliers to many Asian mega-cities rely on imports of surface water because recent rapid urban expansion threatens local groundwater quality. However, shallow groundwater resources beneath these cities are still utilized by private wells irrespective of health implications. If the quality of shallow resources is to be maintained, potentially polluting activities must be encouraged to locate in areas where groundwater is naturally protected. Groundwater vulnerability techniques are an appropriate, low cost management tool for defining both areas of natural protection and areas requiring strict land use controls. The UK vulnerability methodology, adapted for Philippine conditions, enables land to be zoned according to: soil and aquifer properties, depth to groundwater, and proximity to perennial rivers. The resulting 16 groundwater vulnerability zones have been simplified, for routine regulatory use, into a four-zone Development Constraint Map, which identifies the planning controls necessary to protect groundwater quality.
