This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the Roger 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 Roger Wash using better topographic, hydrologic, and hydraulic data.
The purpose of this study is to provide flood and erosion hazard information for Castle Wash for use in floodplain use permitting and floodplain management.
The purpose of this study is to provide flood and erosion hazard information for the Wentworth Wash for use in floodplain use permitting and floodplain management.
The purpose of this study is to provide flood and erosion hazard information for the Old Grandad Tank Wash for use in floodplain use permitting and floodplain management.
The purpose of this study is to provide flood and erosion hazard information for the Craycroft Wash for use in floodplain use permitting and floodplain management.
The objective of the TDN and LOMR submission is provide regulatory discharge rates and floodplain limits along the Flecha Caida Wash using better topographic, hydrologic, and hydraulic data.
The purpose of this study is to provide flood and erosion hazard information for the Geronimo Wash for use in floodplain use permitting and floodplain management.
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.
The Arizona Department of Health Services completed this health consultation at the request of the Arizona Department of Environmental Quality. This consult evaluates whether soil vapors from volatile organic compounds in the subsurface near the Silver Creek Subdivision in Tucson, Arizona are present at levels that may cause adverse health effects.
The Stoneridge subdivision is a growing rural community with approximately 5,000 residents. The Prescott Valley Water Company (Prescott Valley, AZ) provides drinking water for residents in this area. A resident in the community indicated that there is a “paint thinner” type odor coming from the tap water. The Prescott Valley Water Company sampled the water due to request of the resident. On July 27, 2004, the resident called the Arizona Department of Health Services to express his/her concern regarding the analytical results of benzene in tap water samples collected from faucets inside the house. As a result, the Arizona Department of Health Services completed a health consultation to evaluate if benzene and other volatile organic compounds in the water supplied by the Prescott Valley Water Company pose any adverse health effects.
