The Military Engineer L No. 66349 Hawthorne Army Depot Geothermal Plant Progresses At Hawthorne Army Depot, Nev., the U.S Army Corps of Engineers (USACE) Sacramento District continues work to tap natural energy sources to operate a geothermal energy plant. The plant, scheduled to be completed in 2012, will pro- duce up to 30-MW of energy annually. The USACE-Sacramento District is currently drilling two geothermal wells, at an approximate cost of $2.5 million. The drilling is being conducted with the technical assistance of the U.S. Navy, which recently built a 300-MW geothermal fa- cility at the China Lake Naval Weapons Station at Ridgecrest in Californias Mojave Desert. Construction of the power plant will cost approximately $20 million and will be built through a partnership with a local utility. Geothermal energy is produced by drilling into the ground to reach naturally-occurring hot water produced by hot springs or hot spots. The water is then depressurized and turned into steam, which is pumped into a plant and pow- ers a turbine. The turbine spins and produces electricity. The Hawthorne Army Depot geothermal plant, using as its energy source naturally-occurring underground steam and hot wa- ter, will produce all required energy to power the depot and as well as a surplus that will be sold to the commercial grid.

Contamination of water systems can be caused by natural events, unintentional acts, or intentional acts, all of which threaten mission readiness and the well-being of Navy per- sonnel and their families living or working at military instal- lations. The most effective measure to mitigate water con- tamination threats is to detect contamination early enough to allow for a timely response. Real-time water quality moni- toring coupled with automated noti?cation or mitigation systems could address this de?ciency. However, the major- ity of Navy water utilities have not implemented a real-time monitoring strategy due to a lack of proven technologies as well as the associated high costs. The current practice for water quality compliance is to col- lect grab samples manually for laboratory analysis on a weekly or quarterly basis. This practice does not allow water system staff adequate time to respond to changes in water quality and might also miss many poor water quality events occur- ring outside normal sampling events. For overseas or forward bases, manual sampling leaves the water system more vul- Environment & Energy News The Infrastructure Security Partnership (TISP) Become a member today!
