Arsenic Mapping

Help Make a Map by Testing your own Soil

In 2001, Mr. Kevin Doherty (and associates) began a research project on arsenic and its origin and distribution throughout the New England area, specifically central Massachusetts. Several papers were presented at professional conferences, a list of which is provided below.

The goal of our current research project is twofold; (1) use social media to enhance data gathering and (2) identify other areas in the country which, like central Massachusetts, have elevated arsenic concentrations in the soil and identify the causes.
As with any research project, funding is critical to success. Two companies have provided their support to launch this project, Knoll Environmental and New England Testing Laboratory. Mr. Doherty is grateful for their support and for your participation in this important research project.


Sending in a Sample

Email Miles Schelling at or fill out the form below to request a free soil sample test. Miles will respond to your email by sending you a form for you to print out. After you receive this form, collect your soil sample(s). You can use a trowel to dig a few inches under the surface. Greater than 10 grams is needed for each sample so a few handfuls should suffice. Simply take a few handfuls of soil, sift out the small pebbles, and put it in a plastic bag. You can then send your soil and form directly to the testing lab.

The results of your soil test will take approximately 3-4 weeks. Your results will be emailed to the email address you provided.
