The International Boundary and Water Commission, United States and Mexico (IBWC) is a bilateral government body charged with maintaining border and water agreements along the international border between the United States and Mexico. The commission’s American section (USIBWC) is overseen by the State Department, and its origin dates back to the 19th century. The USIBWC’s structure and many functions are defined by treaties signed during the first half of the 20th century.
The commission is involved with helping to enforce the Texas Clean Rivers program. In 1991, the Texas Legislature passed the Texas Clean Rivers Act in response to growing concerns about water pollution. Because of the international nature of the Rio Grande, the state of Texas contracted with the USIBWC in October 1998 to implement the Clean Rivers Program for the Rio Grande along its 1,254-mile international boundary section.
Carlos Marin served from December 2006 as the United States Commissioner of the International Boundary and Water Commission, United States and Mexico. Marin received his Bachelor's Degree in Civil Engineering from the University of Texas at El Paso in 1978. He began his career at the US Bureau of Reclamation where he worked from 1975 to 1979 at offices in El Paso, TX; Denver, CO, and Las Vegas, NV as a civil engineer trainee and as an engineer working on projects such as the Upper Rio Grande Water Conveyance Project and the Pittman Lateral and pump station.
