Our team of scientists tackles a wide variety of issues relating to employee health and safety, indoor environmental quality, and the identification and management of hazardous materials.
Asbestos and Lead-Based Paint
Walsh specializes in the assessment and abatement of asbestos and lead-based paint; our team is one of the Rocky Mountain region's largest and most successful. For asbestos and lead-based paint projects, we can:
- Conduct inspections
- Prepare management and abatement plans
- Obtain bids from abatement contractors
- Oversee abatement and demolition work
Indoor Air Impacts from Groundwater Contamination Plumes
We have cutting-edge expertise in the evaluation and remediation of indoor air impacted by vapors coming from shallow ground-water plumes. Walsh conducted the largest background study of its type in the country, comprising thousands of samples. We have evaluated and remediated buildings impacted by vapors deriving from diesel and chlorinated solvent groundwater plumes.
Molds and Bioaerosols - Walsh offers a complete range of industrial hygiene services related to the investigation, sampling, evaluation, and remediation of indoor molds and fungal growths. Our 9-person industrial hygiene team has experience at dozens of buildings with mold problems, including schools, residences, offices, and factories.
Hazardous Materials Health And Safety - We frequently help clients with the management, handling, and disposal of hazardous materials. This includes worker exposure assessments, health and safety plans, worker protection, identification and disposal of unknown materials, and other task.
Worker Safety - To ensure worker safety, Walsh provides OSHA audits, inspections and training. We can also work with you to develop a health and safety program customized to your operational needs. Our training courses include:
- 40-hour OSHA hazardous waste operations
- 24-hour OSHA emergency response
- 8-hour supervisor's hazardous waste operations
- 8-hour annual refresher
- Confined spaces
- Respiratory protection
- Lockout/tagout
- Blood-borne pathogens
- Hazard communication
Domestic Case Studies
Hazardous Material Management Programs for Various Facilties. Walsh developed health safety programs for hazardous substances for power plants, transmission sites and other facilities associated with a utility operating in four western states. Written corporate programs were developed for arsenic, cadmium, lead, asbestos, and PCBs. The programs were developed after visiting various facilities representative of the utility’s operations. Specific procedures that provided recommendations for training, personal protective equipment, medical surveillance, air sampling, and equipment were prepared for each type of facility. Walsh staff managed the project team, visited sites, researched state and federal regulatory requirements, prepared the programs, met with the stakeholders to discuss the programs and incorporated client comments.
Inspections and Abatement Oversight of Asbestos-Containing Materials at Colorado Mall. Walsh managed assessments of suspect asbestos-containing materials at a Colorado mall scheduled for demolition. The assessment project included performing inspections and re-inspections of approximately 200 individual spaces for asbestos-containing materials. Since the mall was scheduled for demolition, destructive sampling techniques were used to help ensure a thorough survey. Following completion of the inspections, Walsh staff managed the oversight asbestos abatement actions required to remove asbestos-containing materials from the mall prior to demolition.
Asbestos/LBP Services for City and County of Denver (CCOD).
Under three successive contracts, Walsh has performed over 80 asbestos and lead-based paint related inspections, abatement design, and abatement oversight projects for CCOD. Our experience spans a wide variety of buildings and structures, from offices and industrial facilities to sports arenas and convention centers, including Currigan Hall, MinoruYasui Plaza, the CCOD Building, McNichols Arena, the Denver Coliseum, the Denver Jail, and many others.
Indoor Air Quality Investigations, Colorado Department of Transportation Material Testing Laboratory. At the CDOT Materials Testing Laboratory in Denver, Walsh conducted an extensive characterization and remediation of indoor air in a residential neighborhood. At this site, the chlorinated compound 1,1-DCE had migrated to indoor air in residences from a subsurface groundwater plume. Walsh collected approximately 4,000 indoor air samples for VOCs; we believe this is the largest indoor air sampling and analysis effort for low levels of chlorinated solvents in the nation. Risk assessments were performed and monitoring programs were implemented. Walsh also developed risk-based remediation goals and negotiated with the state health department to determine achievable action levels for indoor air, groundwater and soil vapor.
Air Monitoring and Soil Sampling at Denver Fuel Refinery. Walsh provided direct reading air monitoring, worker personal air monitoring, and soil sampling for a 600 million dollar construction improvement project for a fuel refinery in Denver, Colorado.
Asbestos Mitigation at International Airport, Lima, Peru. Walsh Peru performed an asbestos inspection and created an asbestos removal design for the passenger terminal of >Jorge Chavez International Airport in Lima, Peru (conducted by Bechtel).
Contract for Nationwide Owner/Developer of Shopping Malls. Walsh provides services ranging from asbestos and lead inspections, abatement oversight, indoor air quality assessments, subsurface investigations, environmental health and safety policy review, and regulatory support on environmental projects. With the support of E & E, Walsh has provided services in Colorado, California, Washington, Montana, Maryland and Washington, D.C.
