The Town of Andover’s drinking water is considered a “soft water” according to the ranges set by the EPA (Environmental Protection Agency). There is no EPA drinking water standard for hardness, only set ranges to define the degree of hardness: 0 to 75mg/l is considered soft, 75 – 150 mg/l considered moderately soft, 150 – 300 mg/l considered hard, and over 300 mg/l considered very hard. Andover’s treated water is 34 mg/l hardness (also expressed as 2 grains per gallon, GPG). By definition water hardness is the total concentration of calcium and magnesium ions in the water. Hard water is not considered a contaminant, but it does retard the cleaning action of soap and can form a scale on cooking utensils, hot water pipes and heaters. “Soft water” can have corrosive tendencies, but Andover’s water is adjusted before leaving the treatment plant making it non-corrosive but also non-scale forming.
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 firstname.lastname@example.org 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:
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.
Andover’s Drinking Water comes from Haggets Pond and the surrounding 1,422 acres of watershed area. The pond is also supplemented with additional waters from Fish Brook and the Merrimack River.
