Covid-19 Notice from Nashoba Analytical, LLC:

  • Please note: due to the Coronavirus pandemic the lab will discontinue any water sample pickups at residential homes until further notice.  Please refer to your local Board of Health Agent for sample pickups. We will update this notice if anything changes.  Thank you for your understanding.
  • Please have your paperwork filled out before you enter the foyer at the lab.  We are trying to get clients in and out as quickly as possible and having your paperwork filled out before you enter will help.
  • You will be limited to the foyer and we will assist you through a sliding glass window.  Masks are required when you enter the foyer.


Is it time to test your well water?

Our laboratory provides water testing services required for:

  • homeowners
  • real estate transactions
  • Title V inspections
  • mortgage applications
  • day care providers
  • new construction/well permits
  • public water supply compliance monitoring,

to name a few. Maybe you have problems with your water that are either health related or nuisance related – we can help. We can also refer you to companies that can solve your problems as we do not sell treatment equipment, we merely provide unbiased results.

Feel free to browse the website to find out more about our services.  Please call us if you have any additional questions we can answer.

Our packages and pricing along with sampling instructions can be found in the “General Information/Analysis” located in the column on the right hand side of this page.  Please note our typical turnaround time for our packages listed on the Analysis page is 3-5 business days.  Other requests may have a longer turn around time.

If you are calling with questions about your results please have your 6 digit Lab# handy (top right hand corner of either your receipt we give you when you drop off or the report itself).  If you are waiting for your results to arrive by email please check your “Junk” or “Spam” folder before calling us – we sometimes get thrown into Junk or Spam.
