Contact and Lab Hours

Due to COVID-19 restricitons and staffing limitations, we are currently accepting soils for ROUTINE SOIL ANALYSIS and PARTICLE SIZE ANALYSIS only. We are currently unable to accept most hand-delivered orders for analysis. If you have 30 or more samples, please email or call 413-545-2311 to arrange a contactless dropoff outside our building. All other orders must be mailed through the US Postal Service, UPS, FedEx, or other private carrier. On-campus orders may be delivered to the lab via Campus Mail. The lab office will remain closed to the general public until further notice.
