Information Services The Geological Survey Bureau serves as a technical and scientific advisor on matters of Iowa's earth history, landscape features, and the characteristics of rock, mineral, and water resources that occur on the surface and beneath the ground. Service is provided to the general public, to all levels of government and educational institutions, to business and industry, and to technical and professional organizations. Reliable geological information and assessments benefit natural resource management, environmental protection, economic development, and public awareness and understanding of these issues. By selecting from the Service menu we have provided some basic pointers to IGS information services and regulatory duties, and the appropriate person to contact for more details.
