Asbestos Management

Given the wide spread use of asbestos in building materials in the 20th century, the management and abatement of asbestos-containing building material (ACM) has become an important part of real estate management and redevelopment. Accurate delineation, abatement planning and oversight, and reporting are necessary to satisfy not only the requirements of lending institutes, but the law.

WESTECH Environmental Solutions assists property owners, real estate developers and financial institutes in identifying and managing ACM. Proper management of asbestos can result in considerable savings to the client.

WESTECH provides the following asbestos services:

  • Bulk asbestos sampling and delineation
  • Abatement specifications and estimates
  • Third-party abatement oversight
  • Final clearance inspection and air sampling
  • Asbestos management plans
  • Turn-key abatement services
  • Occupational exposure assessments
  • Two-hour asbestos awareness training

Brownfield Assessments and Remediation Oversight

Many states have adopted "Brownfield" remediation programs through which private parties are offered financial incentives or regulatory immunity to undertake clean-up of contaminated property on a voluntary basis; that is, without the burden of regulatory enforcement actions by the state agency. WESTECH Environmental Solutions state-certified professionals are qualified to assist clients in working through state-specific voluntary action programs.

WESTECH offers the following Brownfield remediation services:

  • Environmental Due Diligence
  • Asbestos and Lead Paint Sampling and Abatement Oversight
  • Hydrogeologic Site Assessments
  • Risk Assessment and Risk-based Corrective Action
  • Remedial Design and Implementation
  • Storage Tank Management Services

Environmental Due Diligence (Phase I, II and III)

Over the past two decades, awareness of what constitutes an environmental hazard forces owners, developers, and lending institutions to examine past land use practices to determine whether a potential hazard exists.

WESTECH Environmental Solutions help sellers, purchasers, and lenders estimate the extent of their possible exposure by performing an environmental site assessment (ESA) prior to conveyance. The purpose of the assessment is to evaluate the potential for environmental contamination at the site. Conducting an ESA early in the planning process can help to eliminate unpleasant surprises and unexpected costs.

WESTECH approaches ESAs in three phases; each phase is dependent upon the information gathered in the previous phase.

Phase I - Sites that are found to be clean after preliminary investigation need not go beyond Phase I. Others may require the more detailed study and sampling that is part of a Phase II investigation.

Phase II - Testing is often called for sites with a history of improper waste management practices or where contaminants may have migrated to the soil, groundwater, or surface water.

Phase III - Site Remediation--Depending on the type of contamination, many types of corrective actions can be utilized to bring a property into useable compliance.

Hydrogeologic Site Assessments

Assessing the extent of chemical contamination in the subsurface soil and groundwater is often a critical and defining step in the process of property inspection. WESTECH Environmental Solutions geologists and environmental scientists provide the field experience and technical expertise needed to investigate the extent of contamination problems.

WESTECH offers the following hydrogeologic site assessment services:

  • Assessment and delineation of chemicals in soil, groundwater and surface water
  • Groundwater monitoring plans
  • Characterization of unsaturated and saturated soils and bedrock
  • Aquifer testing and characterization
  • Analysis of soil and water samples
  • Computer modeling of contaminant plumes
  • Contaminant fate and transport determination

Indoor Air Quality

Indoor air quality issues, including mold, have the potential to effect the health of building occupants or inhibit the sale of a property. Indoor air quality can be reduced/affected by a number of particulate, chemical and biological elements. WESTECH Environmental Solutions industrial hygienists and technicians have knowledge and experience that enable them to identified potential concerns and, if needed, develop sampling schemes, conduct the sampling and interpret the results. By addressing indoor air quality.

Indoor air quality issues that are encountered include:

  • Carbon monoxide, carbon dioxide
  • Sewer gas (methane, hydrogen sulfide)
  • Lack of fresh air intake
  • Building material off-gassing
  • Mold

Lead Management

Lead-based paint is often found in homes and multi-unit residential buildings built before 1978. Paint chips and lead dust can both contribute to adverse health effects in children and adults. Lead-based paint that is in good condition, does not typically represent a hazard. Proper management of lead-based paint can result in considerable savings to the client.

Services provided by WESTECH Environmental Solutions to assist clients in managing lead based paint includes:

  • Lead-based paint surveys
  • Lead-based paint hazard assessments
  • Lead-based paint risk assessments
  • Post remediation clearance testing

Lead contamination can also be found in drinking water or soil. WESTECH has been involved in multiple projects in which the soil was evaluated for lead content as the result of a shooting range, industrial activities or contamination from the exterior of a building painted with lead-based paint.

WESTECH assists property owners, real estate developers and financial institutes in identifying and managing lead-based paint and lead contamination of soil.

Remedial Design and Implementation

The process of property remediation involves designing, installing, and sometimes, maintaining clean-up or remediation programs for contaminated soil, groundwater, or surface water.

WESTECH Environmental Solutions knows that each site is unique and that many factors, including the intended use of the property and prevailing laws and regulations, must be considered before settling on the most appropriate remedial action.

WESTECH offers a variety of skills and services to address this complex problem:

  • Feasibility studies and pilot tests
  • Risk-based corrective actions
  • Remedial system design and action plans
  • Permitting (NPDES, permit-to-install, permit-to operate, wastewater discharge)
  • System installation, operation and maintenance
  • Stormwater pollution prevention plans
  • Monitoring and reporting
  • Construction management and oversight

Storage Tank Services

Federal regulations require that owners of underground storage tanks (UST) comply with the December 22, 1998 deadline for upgrading UST systems to incorporate leak detection devices, among other requirements.

WESTECH Environmental Solutions can assist an owner/operator with development of a tank management program to address USTs not in compliance with federal regulations. In addition, WESTECH can assist a developer or purchaser in making a determination as to whether USTs were abandoned on a property and if the operation of these USTs has adversely impacted the property.

WESTECH offers the following storage tank closure services:

  • Storage Tank Closure Planning and Permitting
  • Storage Tank Closure Oversight
  • Storage Tank Closure Assessment
  • Corrective Action Plans
  • Hydrogeologic Site Assessments
  • Remedial Design and Implementation
  • Groundwater Monitoring

Wetlands Assessments and Delineation Studies

Federal and state regulations addressing the protection of natural resources affect new land developments or the expansion of an existing one. Section 404 of the Clean Water Act requires assessment of properties for the presence of wetlands prior to initiation of land-disturbing activities.

If wetlands are present at a site, this can have a profound effect on the viability of the development project. The accurate determination and, if present, delineation of wetlands is an essential and critical part of the development process.

To comply with these regulations, WESTECH Environmental Solutions ecologists can perform the following wetland assessment services:

  • Preliminary assessment for wetlands
  • Routine wetlands determination by assessment of hydrology, wetland plants (hydrophytes) and soil type
  • Wetlands delineation
  • Coordination of jurisdictional determination by the US Army Corp of Engineers
