How do I get my water tested?

If you are an Andover Municipal Water Customer, you may have your water tested at the Water Treatment Plant Laboratory.  Customers must first contact the Lab Director/Environmental Coordinator at (978) 623-8873 or via email at for more information.

We do not test well water or businesses regardless of location.

You will be asked what specific concerns you have with water quality before we can test your water.  After a staff member has spoken with you, you will be asked to stop by the Water Treatment Plant located at 397 Lowell Street to pick-up sample collection bottles and sampling instructions.  You will be required to leave your name, address, phone number and email address for communication purposes.  No Walk-Ins will be accepted. 

Samples must be returned to the laboratory for analysis, within 24 hours of sample collection, along with a completed Chain of Custody.  We will only accept samples that have been collected in the sample bottles supplied to you.

The Water Treatment Plant will analyze water samples for the following parameters:

•    pH

•    Color

•    Turbidity 

Depending on test results and discussions with the customer, samples may be further analyzed for manganese and iron.  These tests are done as a courtesy and at no charge to residents; and analysis is performed using in-house instrumentation. 

There is a minimum two-week turn-around time from the time samples are delivered to the laboratory until a report will be issued. A sample report can be found here: View Sample Report

Residents that are known to have a partial or full lead water service line may request analysis for Lead and Copper in their water.  Testing for these analytes require specific sampling containers and instructions.  Presently, samples are sent to an outside laboratory for analysis. Samples are held at the water treatment plant until our contract laboratory can pick them up.  It may take up to four weeks for sample results to be reported to you.

Please refer to the Annual Water Quality Report for more detailed information regarding Andover’s water.
