This document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
During the period of 1965 through 1984, Maricopa County operated a landfill leased from the U.S. Bureau of Land Management. In 1982 the County leased a separate parcel from the State for the development of a new landfill. The landfill stopped accepting waste in 1998.
To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.
This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.
The Flagstaff Regional Plan 2030: Place Matters (Regional Plan) updated the Flagstaff Area Regional Land Use and Transportation Plan (2001). The vision and goals for the Regional Plan are directed toward creating a cohesive and sustainable land use and development pattern resulting in a contextsensitive and efficient transportation system that supports economic development, multimodal transportation, and improved safety and accessibility.
This Land Use Survey, conducted for the Cochise County Planning Department, was designed to elicit citizen opinions about the future pattern of growth in Cochise County and land use issues in areas outside of City limits. This project is an initial step in the County’s "Envision 2020: Land Use Planning in Cochise County" process, developed to measure citizen opinions on how growth is currently managed in the County and how to manage future growth.
A majority of the work performed by ADEQ's Nonpoint Source Program is funded by Clean Water Act grants, awarded by the U.S. Environmental Protection Agency which requires States to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvement in water quality resulting from program implementation.
In March 2004, the U.S. Environmental Protection Agency requested information on efforts to monitor and protect children from exposure to lead in drinking water at schools. The Arizona Department of Health Services reviewed the state lead poisoning registry, and analyzed drinking water samples from 45 randomly selected schools. The Office of Environmental Health provided this consultation to help document our findings and supplement our response to the EPA. This work was also undertaken to help provide useful information should hazardous waste sites be discovered in the future near these schools. We also wanted to apply the ATSDR health assessment process in support of state and federal efforts to protect the health of children.
The objective of this health assessment is to provide an evaluation of the health risks that may result from exposure to abandoned mine tailings in Klondyke, Arizona. The tailings are remnants from an earlier flotation mill and mining operation that was in business from the early 1900's until 1950. Environmental data indicate that the 70,000 cubic yards of tailings that remain on the property have contaminated the soil and nearby creeks with heavy metals. This report evaluates the potential pathways of human exposure to the contaminated media. The contaminants of concern further evaluated are lead, arsenic, cadmium, mercury, manganese, and boron. Child health issues and community concerns are also an integral part of the evaluation.
Provides a thoughtful and timely assessment of how Pima County's practices and policy proposals in land use stand up under the test of nationally recognized principles of smart growth.
