Mr. Blandford is a Senior Vice President and Principal Hydrologist with more than 30 years of experience as an environmental consultant. He has led numerous projects involving complex technical, regulatory, and legal issues. Mr. Blandford’s experience includes the identification, assessment, and development of groundwater resources; design and installation of water supply and groundwater remediation well fields; analysis of brackish groundwater resources and seawater intrusion in coastal aquifers; site investigation where groundwater has been impacted by oil-field brine, acid-mine drainage, leach solutions, organic solvents, or other types of contaminants; and  permitting for water rights appropriations and transfers, managed aquifer recharge, and environmental site investigation and closure. One of Mr. Blandford’s specialties involves the development or application of quantitative models of groundwater flow and solute transport. He has supported his clients in many public forums and has testified as an expert in administrative hearings and trials regarding water supply, water quality, and regulatory issues.

Mr. Blandford manages projects or programs for county, state, and federal regulatory agencies; energy and mining companies; water providers; water districts; tribes; and private parties. Examples of past and current clients include the U.S. Environmental Protection Agency (EPA); the Texas Commission on Environmental Quality (TCEQ); Pioneer Natural Resources; Freeport McMoRan (FMI); Hopi Tribe; University Lands (Texas); Texas Water Development Board (TWDB); New Mexico Environment Department (NMED); Colorado River Municipal Water District (CRMWD); Padre Dam Municipal Water District (PDMWD); County of Inyo, California; Goliad County Groundwater Conservation District; Los Alamos National Laboratory (LANL); and multiple municipalities, including Albuquerque and Rio Rancho, New Mexico, and Lubbock, Texas.
