Research Interests

Currently my work focus includes:

• The northern segment of the Edwards Balcones Fault Zone Aquifer and water management with regard to endangered species

• Brazos River alluvium aquifer

• Groundwater/surface-water interactions

• Co-mingling of groundwater in aquifers

• Naturally occurring arsenic in the Trinity aquifer

• On-site and decentralized wastewater treatment research

• Water management in developing countries


Baylor University Geology Doctoral Candidate Receives Prestigious Award for Groundwater Research

Current Research Projects

Groundwater availability modeling of the Trinity aquifer in McLennan County. A project for the newly created Groundwater Management District in McLennan County.

Sustainable groundwater use in the Hacienda Baru National Wildlife Refuge in Costa Rica. Water and wastewater management in developing countries and the potential for on-site wastewater treatment systems to reduce emerging contaminents.

Dr. Yelderman combines field methods with classroom instruction and his hydrogeology classes use both aquifer tests and numerical modeling in aquifer analyses. Students design tests, install wells, and analyze the tests they performed in the field. Students usually present thesis findings in oral or poster format at regional and national meetings and many have won awards.

Dr. Yelderman is a member of GSA, NGWA, NOWRA, TOWA, and WEF. He has served as secretary treasurer for the Hydrogeology Division of GSA, as groundwater chairperson for AEG - Texas Section, and as director and groundwater chair for the TAS. He is Director of the Baylor Wastewater Research Program and Baylor in Costa Rica.
