Geology & Hydrogeology
MDA's analysis varies from regional assessments and the mapping of surface drainage, seasonally flooded areas, aquifer recharge areas, and general lithology/aquifer identification to more detailed investigations involving all aspects of hydrologic exploration.
Remote sensing is a recognized tool for detecting and mapping the surface indicators of potential groundwater accumulation, storage, transmission, and recharge. Observable indicators on satellite imagery and aerial photography include regional tectonics, fractures and lineaments, drainage patterns, lithologies, soils, and vegetation anomalies. When combined with regional geological and meteorological information and local hydrologic data, groundwater potential can be assessed and prospective targets ranked according to their probable suitability as aquifers.
This type of analysis can vary from regional assessments and the mapping of surface drainage, seasonally flooded areas, aquifer recharge areas, and general lithology/aquifer identification to more detailed investigations involving all aspects of hydrologic exploration. Detailed exploration includes assessments of flow from potential aquifers based on existing or test well data, location of producible fractures, drilling, and distribution of the water found. A hydrologic analysis is a combination of the geologic structure, lithologic, lineament (potential fractures), and chemical analyses plus identification of specific drilling locations.
Structure and Lithography
For Water Exploration/Management studies, MDA generally performs our standard lithology and structural interpretation but we expand our interpretation to also include maps of Hydrolithologic Units (i.e., geologic maps that group together formations with similar water-bearing properties). Our structural analysis is used to evaluate groundwater flowpaths.
