President Clinton signed legislation authorizing a study on the most cost-effective way to improve the Jicarilla's failing water system. The new law authorizes the Bureau of Reclamation to conduct a one-year study to determine the most feasible way of developing a safe and adequate water supply for the northern New Mexico tribe. "The need for an adequate water supply system on the Jicarilla reservation goes beyond basic quality of life needs,'' Sen. Pete Domenici, R-N.M., said July 11 in a news release. The senator said there are deficiencies in the water system that need to be addressed, both for the existing population and to meet the tribe's future needs. The measure was introduced last October by Rep. Tom Udall. The president signed it July 10. The tribe's water system is owned and operated by the Bureau of Indian Affairs. It has been cited by the Environmental Protection Agency for violations of federal safe drinking water standards, and it has been operating without a federal discharge permit.
