Indoor Air and Environmental Quality

Solutions EHS offers indoor air and environmental quality (IAQ / IEQ) services overseen by an experienced Certified Industrial Hygienist (CIH#9922). Solutions EHS will help your facility management team develop a practical and cost effective approach to address indoor environmental issues and prevent future problems.


Indoor Air Quality Assessments

Indoor air quality (IAQ) problems often have multiple contributing factors and require a flexible and diagnostic approach. Solutions EHS can conduct an IAQ assessment to identify sources of chemical or biological contamination, entry pathways, and dispersion mechanism. Our services include:

  • Physical inspection of the building’s outdoor environment, the complaint area, a control area, and heating, ventilation, and air conditioning (HVAC) systems.

  • Monitoring of building temperature, relative humidity, carbon monoxide, and carbon dioxide.

  • Initial screening for total volatile organic compounds (TVOCs).

  • Infrared guided and direct moisture measurement when moisture intrusion issues are suspected.

  • Recommendations for more specific IAQ monitoring when additional testing is warranted.


Legionella Management Planning and Testing

Solutions EHS can help your building or healthcare facility develop an ASHRAE 188 compliant water management plan for plumbing systems, cooling towers, decorative fountains, and other building water systems that pose a risk for Legionella transmission. A Solutions EHS expert can help reduce your facility's Legionella risk by:

  • Establishing a written description of your building water systems and process flow diagrams.

  • Identifying where potentially hazardous conditions could occur in your building water systems;

  • Implementing and monitoring control measures;

  • Establishing validation methods for the control of Legionella in your building’s water systems.

  • Collecting water and swab samples for CDC ELITE Certified Laboratory Analysis.

  • Determining corrective actions in response to systems performance outside of established control limits.


Indoor Air Quality Testing

Complex indoor air quality (IAQ) problems may require specialized methods to identify specific contaminants and facilitate their removal or control.  Solutions EHS offers a variety of advanced environmental monitoring methods, to include:

  • Time-integrated air sampling using EPA, OSHA, and NIOSH validated methods. Techniques may include laboratory analysis to identify volatile organic compounds (VOCs) or aerosols, including formaldehyde, ozone, combustion products, heavy metals, microbial VOCs (MVOCs), bioaerosols, or allergens.

  • “Whole air” sampling using EPA methods TO-14A and TO-15 to assess a broad-range of hazardous air pollutants.

  • Long-term IAQ monitoring and data-logging using direct reading instrumentation.

  • Tracer gas testing to evaluate ventilation-related IAQ problems and paths of contaminant infiltration.


Health Care Facility HVAC Measurements

ASHRAE Standard 170, “Ventilation of Health Care Facilities” defines the minimum ventilation required to control airborne contaminants in patient occupied areas. Hospitals and health care facilities should regularly monitor their critical areas for compliance with this standard which is referenced by several Joint Commission standards and the Facility Guidelines Institute (FGI) Guidelines for the Design and Construction of Health Care Facilities. A Solutions EHS Certified Industrial Hygienist (CIH) will independently measure and assess your critical areas for:

  • General indoor air quality parameters (i.e. temperature, RH%, carbon dioxide, and carbon monoxide).

  • Viable and non-viable microbial contamination.

  • Direct measurement of supply and return air to assess room air exchange rates.

  • Measurement of outdoor air exchange rate (percent outdoor air) using direct or surrogate methods.

  • Differential pressure measurement to ensure proper room pressurization.
