Due to the public health concern caused by the COVID-19 virus, UNH administration made the decision to close all University offices and adjust diagnostic services until further notice. We appreciate your understanding and patience during this uncertain time.

Walk-in and mail-in samples will no longer be accepted for any diagnostic service until further notice. (Samples received after March 17 will be processed when services resume)

Submitting Samples at Spaulding Hall

Soil, insect and plant samples may be left in bin outside room G28. Plant samples may also be left outside room G37.

 

*Attention: Beginning May 20, 2019 there will be many construction projects on campus including major construction around Spaulding Hall throughout the summer. Please read the details below if you plan to drop-off a plant, insect, or soil sample.

Option 1. The Rudman Hall loading dock will be available for short term parking (turn on your hazard lights). To get there, drive down College road and turn left onto the short-unmarked road just before Rudman Hall. The loading dock will be directly on your right. Enter Rudman Hall from the College Road entrance and walk down the hall, through the double doors, and up the ramped walk-way. This will bring you to Spaulding Hall. Turn left at the top of the ramp and G28 will be down the hall on your right.

Option 2. Alternatively, Academic Way (near the end of Spaulding Hall) will be closed off shortly after 5/20/19 but a pedestrian path will be maintained along Academic Way from Arts Way to Morse circle/DeMeritt Way. The pay station parking on Academic way will still be available. To access Spaulding, walk down the pedestrian path to the circle and enter Spaulding Hall from the West entrance (across from Rudman).  Once in the building take the staircase on your left to the ground floor. Then, take two left turns and room G28 will be down the hall on your right.
