    Granite State Analytical has been providing accurate laboratory testing services since 1987.

    Our niche market is drinking water where we serve private well owners, small public water systems, major municipalities, and other laboratories throughout New England. In addition to our fully accredited testing services, we also provide Certified Operator Services to small public water systems throughout NH. We have built our reputation on exceptional service, knowledgeable personnel, and state of the art technology. Please explore our web site, and contact us with any questions you may have.

    Our Derry office front lobby is open 24/7.  Sample kits are available in the lobby to be picked up and there is a fridge for dropping off samples after hours.  We accept samples on Saturdays (except holidays) via the after-hours sample fridge.  Analysis of samples received on Saturday will begin that day at 5pm.

    In August of 2014 A&L Laboratory in Auburn, ME became a division of Granite State Analytical, clients in need of services in Maine can visit their website at A&L Laboratory 

    Residential Services

    We provide testing that can help you determine the water quality in your home whether it comes from a private well or a public water supply, and we help you understand and interpret the results. Granite State Analytical offers flexible courier services as well as multiple pick-up and drop-off locations for reliable delivery of your test kit(s) and water samples.

    Public Water Services

    If you own and/or maintain a community system, non-community non-transient system, or transient system, the analytical requirements for owning a Public Water System can sometimes be a challenging task. We have certified operators on staff who are licensed in the state of New Hampshire for Grades I-III Treatment & Distribution.

    Laboratories Take Note!

    You can subcontract with Granite State Analytical to take care of those tests you are not equipped to handle. Check out our Laboratory Resources page for more information.
