Quarterly Indoor Air Quality (IAQ) Assessments and Mold Surveillance Program

Program Overview & Coordination

Barnstable Public Schools and EnviroMed Services have discussed and established a seasonal/quarterly indoor air quality (IAQ) and mold surveillance approach as part of the District's ongoing commitment to healthy learning environments. 

These Quarterly Assessments allow indoor conditions to be reviewed at different times of the year, when factors such as occupancy, ventilation patterns, and seasonal changes can influence building performance. This approach supports: 

• Proactive building oversight

• Trend tracking over time

• Early awareness of changing indoor conditions 

• Informed facilities and operational decision-making. 

This program works in conjunction with the Facilities and Safety Team's ongoing review of building conditions. Facilities staff routinely evaluated incoming facilities tickets, operational observations, and building-related concerns throughout the year. When additional evaluation or verification is warranted, Facilities coordinates directly with EnviroMed to perform isolated walkthroughs, testing, or follow-up assessments, as appropriate. 

Together, this coordinated approach supports routine monitoring and proactive evaluation of indoor conditions, reflecting Barnstable Public School's continuous commitment to maintaining clean, safe, and well-managed learning environments year-round. 

July 2026 Quarterly Assessment Summary

A Quarterly Indoor Air Quality (IAQ) Assessment and Mold Surveillance was conducted during the week of July 19–25, 2026, at Barnstable Public Schools.

The assessment included walkthrough evaluations of each building and real-time air monitoring to review current indoor conditions in comparison to recognized indoor air quality guidelines established by OSHA and ASHRAE.

Overall findings determined that indoor air quality conditions were acceptable and the schools were fit for normal occupancy.

During the assessment, temperature and relative humidity readings outside of the recommended ranges were observed in portions of the buildings. Recommendations were provided regarding continued HVAC operation, preventive maintenance, and management of relative humidity conditions.

As part of the quarterly walkthroughs, buildings were also reviewed for visible signs of microbial growth and conditions that could support mold growth. Where applicable, observations and recommended actions are identified within the individual school summaries.

Please view the draft quarterly summaries below for school-specific findings, observations, and recommendations.
