Broadbent’s success as a firm is demonstrated by our ability to maintain long-term relationships with valued clients. Producing quality results during environmental site investigations, and other projects, is the product of careful attention to three key components of project management (1) adherence to project scope, (2) compliance with budgetary requirements, and (3) meeting schedule obligations. The result of carefully monitoring these components, during the course of a project, is a quality product delivered to clients on time and on budget; our primary objective as environmental and engineering professionals. Adherence to a project scope is an often overlooked project component that Broadbent personnel monitor during weekly staff meetings and by maintaining open communication with the client and project staff.

Environmental Experience – Landfill Remediation

Posted by & filed under Environmental.

Kings Beach, California On behalf of the USDA – Lake Tahoe Basin Management Unit (LTBMU), Broadbent conducted several rounds of groundwater and volatile gas vapor (via PID instrumentation) monitoring and reporting activities for four existing groundwater monitor wells associated with a former landfill site. Additionally, Broadbent conducted two rounds of additional groundwater characterization activities, via Geoprobe boring installation and water sampling, in the area of MW-4. These activities were conducted during high and low water table periods of the year to determine if groundwater had been impacted above a shallow clay layer. Broadbent also facilitated surface water sampling activities for two streams transecting the forme

Case Study: Pump and Treat Remediation

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

South Lake Tahoe, CA – Broadbent provided third party review and documentation of historical operation and maintenance activities for an existing on-site groundwater pump and treat remediation system, and provided recommendations for system modifications and future operations. Constituents of concern included PCE, TCE, DCA, and vinyl chloride. Recommendations and actions included: Repairing system components, Testing system operations, And modifying the system to address iron fouling problems. Broadbent was retained to operate the system and monitor associated wells. Through a series of repairs and tests, and minimal system operation time, it was determined that the system was no longer needed, as it was no longer extracting impacted water associated with the landfill. The USDA-Tahoe National Forest (TNF) approved to terminate remediation Read More »

Environmental Experience – Total Petroleum Hydrocarbon Impacts

Posted by & filed under Blog, Environmental.

Broadbent managed a project in Sparks, NV, where a diesel fuel release was discovered, emanating from a failed dispenser piping bushing (the facility operates two diesel fuel underground storage tanks (USTs), one 5,000 gallon capacity and one 8,000 gallon capacity). Initial soil sampling assessment activities, conducted via hand sampling at the point of release, found total petroleum hydrocarbon (TPH) diesel impacts present at 1,700 mg/kg and 16,000 mg/kg. Subsequent soil characterization activities were conducted via installation and sampling of two GeoProbe soil borings, found TPH diesel impacts present at 1,100 mg/kg in one boring at ~10.5 feet below land surface (bls), and 2,500 mg/kg in the second boring at ~15 feet bls. Additional site characterization activities were conducted using drilling Read More »

Environmental Experience – Heating Oil and Underground Storage Tanks

Posted by & filed under Blog, Environmental.

Broadbent has been providing professional Certified Environmental Manager (CEM) services to a large Nevada School District, relative to heating oil underground storage tanks, since 1996. This includes work at numerous facilities, within the past five years. Conducted activities include: preparation of tank removal contractor specifications; contractor bid solicitation; contractor selection; oversight of tank cleaning and removal activities; collection of tank closure assessment samples; and preparation of Tank Closure Assessment Reports. Where impacts (primarily diesel range organics and some MTBE) have been discovered, additional site characterization activities have been conducted, including: Work Plan preparation and implementation; soil boring drilling and soil sample collection (using multiple drilling techniques, including GeoProbe, Hollow stem auger, air rotary, and sonic); soil boring completion as groundwater Read More »
