41. DRAFT REPORTS CONFIRM HANFORD TANK FARM LEAKS CONTRIBUTING SOURCE OF GROUNDWATER 1997.11.25 http://www.hanford.gov/press/1997/97-096.htm

Release date: November 25, 1997 For more information contact: Guy Schein, (509) 376-0413, guy_d_schein@rl.gov DOE DRAFT REPORTS CONFIRM HANFORD TANK FARM LEAKS CONTRIBUTING SOURCE OF GROUNDWATER CONTAMINATION As part of its continuing evaluation of groundwater contamination at Hanford, the U.S. Department of Energy has confirmed that past leaks from Hanford's single-shell tank farms are a contributing source of groundwater contamination in the site's 200 Area. Although the department previously identified the single-shell tanks as a likely contributor to groundwater contamination, the first of several draft Resource Conservation and Recovery Act (RCRA) groundwater quality assessment reports of the Waste Management Areas in Hanford's 200 Area provide technical confirmation of this source of groundwater contamination. Other known sources of groundwater contamination include cribs, ponds, trenches, and ditches. The groundwater that has been contaminated is not a source of drinking water and is regularly monitored and compared to acceptable water quality specifications. The site is also implementing protective measures to prevent the migration of contaminants from the area. These measures include traditional methods for treating groundwater contamination "pump and treat" and consideration of innovative technologies. Energy Secretary Federico Pe¤a, as part of his commitment to place new emphasis on both the study and cleanup of groundwater contamination at Hanford, has assigned the Under Secretary, Dr. Ernest Moniz, to work with the Environmental Management Program, the Hanford Site, an expert panel (currently studying tank farm contamination in the subsurface) and regulators to provide an integrated assessment of the scientific methods used to study groundwater contamination and their use in efforts to define site priorities and programs.

Maps, Figures, Photos Charnock MTBE Cleanup Work is underway to clean up groundwater polluted with the gasoline additive MTBE in Southern California's Charnock Sub-Basin. Responsible parties are paying over $3 million per year to provide replacement water to Santa Monica and Culver City residents. The Charnock groundwater sub-basin is located in Southern California within the communities of West Los Angeles and Culver City ( Site Location Map , 111 KB PDF) and is an important source of drinking water for the cities of Santa Monica and Culver City. The City of Santa Monica sought assistance from EPA after shutting down a number of its drinking water wells in 1996 due to the presence of increasing levels of the gasoline additive Methyl tert Butyl Ether (MTBE). Affected residents of Santa Monica and Culver City are currently receiving replacement water. The Charnock Project involves the investigation and cleanup of MTBE and other gasoline-related pollution in areas affecting water quality in the Charnock Sub-basin (see map listed in the Table of Contents below) and the restoration of this sub-basin for use as a drinking water supply.

Page contains both student's and teacher's introductions. From the US Dept of Energy Office of Environmental Management. http://www.em.doe.gov/soda/index.html

EM Home Attention Science Teachers Try out Soda Bottle Hydrology Classroom Activities with Water Hydrology is the study of water. The hydrologic cycle or water cycle is the endless recycling process water goes through on Earth. Heat from the sun makes water evaporate. The water vapor rises into the atmosphere, where it cools and condenses forming clouds. The clouds release water through precipitation (rain, sleet, snow, etc.). The water falls onto the ground and into the ocean. Some of it is absorbed into the ground and some of it runs along the surface to the ocean. Then the water starts to heat up again and goes through the cycle again. Teacher's Introduction The following activities are designed to give students a better grasp of concepts relating to groundwater aquifers , and hydrology . The first activity, Pre-Lab Construction, sets up the materials for the following activities. Activities can be conducted in sequence or individually; feel free to improvise or expand at any level. The suggested materials are commonly available at drug, hardware, and grocery stores. They are listed in the order they are used in the activities. Depending on what grade level you teach, and your class objectives, these activities can be used individually or collectively. They can be conducted as a demonstration (especially for younger students) or as a laboratory activity by students in higher grades. Younger students may have difficulty performing the experiments without making a mess. Students who will perform the activities can collect clear plastic two-liter soda bottles at home about two weeks before the class begins these activities. For the activities to work best, students should collect only clear bottles with formed (not attached) bottoms. The bottles need to be stabilized for the activities to work well without making a big mess. This can be done with a ring stand and a clip or rubber band. Also, each activity must be started with dry sand.
