Due to the COVID-19 pandemic, the lab is only accepting samples from residential customers that have been purchased here at the online store. Kits can be shipped to you or picked up at the lab but they must be purchased online first. If you don’t see what you want to test for here, please call the lab for assistance.

Please note, samples for the following test kits must be collected and delivered to the laboratory only on WEDNESDAYS and THURSDAYS between the hours of 8 am and 3 pm:

– Standard Package
– Standard Title 5 Package
– Annual Minimum Package
– All packages including analyses for Nitrate, Nitrite, and/or Orthophosphate

As always, please be sure to collect samples immediately prior to bringing them to the laboratory. If you have purchased one of these test kits and are unable to bring your sample to the laboratory within the time ranges specified above, please call us at 978-777-4442 to discuss options.
Please note: because of short staffing we are shipping kits only once per week. If you need your kit faster you may pick it up at the lab. To do that choose Local Pickup when you are checking out.

Thank you for your patience during this time.
