This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the Trails End Wash located in Pima County, Arizona. The objective of the TDN and LOMR submission is to provide regulatory discharge rates and floodplain limits along the Trails End Wash using better topographic, hydrologic, and hydraulic data.

This study was prepared to provide a drainage condition for Tanuri Wash. Hydrologic and hydraulic analyses were conducted. A floodplain map was created based on the hydraulic analysis.
From May 2005 to June 2005, the Arizona Department of Environmental Quality conducted a study, Potable Well Sampling Task 4.0, to determine if the chromium and chromium VI plume due to the discharge of the Pacific Gas and Electronic Topock Compressor Station has migrated under the Colorado River and impacted water supplies in Arizona. The ADEQ investigated the total chromium and hexavalent chromium (chromium VI) concentrations in (1) public water supply wells, (2) combined industrial and domestic water supply wells, and (3) private domestic water supply wells at Topock and Golden Shores, Arizona. The communities of Topock and Golden Shores have expressed their concerns regarding the findings. Thus, the ADEQ requested the Arizona Department of Health Services to evaluate the potential health effects of exposure to well water contaminated with chromium.
