Big Jobs in Thin Places – Construction Projects in Historic Western Towns

Posted by & filed under Blog, Cultural Resource Management.

When: April 27th, 2019 at 1:30 PM Where: APWA Conference, Laughlin, Nevada Project Archaeologist, Stuart Rathbone, discussed the delicate nature of archaeological deposits in historic western towns and how construction projects are adapting to the challenges these elements present. Abstract: Historic western architecture has an unusually ‘thin’ quality, with stylistic façades applied to simple wooden frames. The relatively young age of western towns means archaeological deposits are noticeably ‘thinner’ than are typically found in older settlements. In combination, this ‘thinness’ means that construction projects in western towns are occurring within particularly delicate historic environments. This presentation reviewed how a number of different western towns have responded to this challenge with varying levels of success. If you would like to know Read More »

Case Study: Solvent Release Characterization & Remediation

Posted by & filed under Blog, Environmental, Planning and Permitting.

In 2003, chlorinated volatile organic compounds (CVOCs) associated with dry cleaning operations were discovered in the groundwater beneath a former dry cleaning facility in Las Vegas, NV. Broadbent was contracted to conduct on- and off-site characterization activities. Broadbent prepared and implemented a detailed Site Characterization Work Plan (Work Plan) which included design, construction oversight, development, and soil and groundwater sample collection from seven groundwater monitor wells. Groundwater sample laboratory analytical results indicated the on- and off-site presence of dissolved tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE) and vinyl chloride (VC) constituent concentrations in groundwater in excess of their respective Maximum Contaminant Levels (MCLs). Broadbent prepared and implemented a subsequent Work Plan to monitor groundwater beneath the site and to conduct VC Read More »

Environmental Experience – Confidential Mine

Posted by & filed under Blog, Environmental.

Broadbent has been working on this project since 2006. The company plays a key role in remediation operations at this historic mine site, a CERCLA site listed by the federal EPA on the National Priorities List (Superfund). Broadbent Reno Division Manager, Randy Miller, was the Project Manager from 2006 – 2010, and is the current Project Supervisor. At the site, the client is responsible for capturing and treating acid rock drainage from three seep/spring locations. Broadbent supports operations at the site by providing operations management, safety management, and system operators to operate the on-site treatment systems including a sulfate reducing bioreactor and high density sludge plant, both of which are designed to collect and treat acid rock drainage at the Read More »

Site Conceptual Model of Groundwater

Posted by & filed under Blog, Environmental, Water & Wastewater Facilities Operations.

Broadbent was contracted by a major petroleum and energy company to provide a third party review and preparation of a Site Conceptual Model for a former aerospace facility in the Central Valley of California. Analysis of historical data indicated that former site operations activities had resulted in contaminant impacts to groundwater. Primary contaminants of concern (COCs included volatile organic compounds (VOCs). On the site, groundwater occurs at approximately 40 feet below ground surface (bgs) and flows towards the east. A soil vapor extraction (SVE) system was installed in 1999 and operated through 2000. A groundwater extraction and treatment system (GWETS) was also installed in 1999 and has operated continuously, since then. The objective of the scope of work performed was Read More »
