Silurian-Devonian Aquifer Characteristics

This aquifer is composed of bedrock units from two major systems of geologic time, the Silurian and the Devonian. They are usually described as a single aquifer package because, regionally, they are composed of similar carbonate rocks that are hydraulically connected and yield similar water quality. Locally, however, there are differences in terms of rock types and water quality, and thus these two units are sometimes considered independently.
