1 Large to enormous quantities of fresh water from hard, highly karstified or fractured, Tertiary agelimestone aquifers.

Map Unit

2 Very small to very large quantities of fresh water fromalluvial and coastal aquifers generally composed of gravel and sand with some silt and clay.

3 Very small to large quantities of fresh water from hard, low capacity, fractured, and karstified limestone.

4 Unsuitable to small quantities available from fractures and solution cavities in soft, fine-grained, chalky limestone and alluvial aquifers.

5 Unsuitable to very small quantities of fresh water from clays and shales along the coast and in interior valleys. Isolated springs may yield small quantities of water.

6 Unsuitable to very small quantities of fresh water available from fractures in volcanic and metamorphic basement rock. Isolated springs may yield small quantities.
