Thermo Fisher Scientific Inc., the world leader in serving science, is participating in the massive remediation of the Muddy River, in cooperation with Simmons College, by supplying instruments that are used to screen for levels of sulfur in river sediment. Muddy River is part of Boston’s “Emerald Necklace,” designed by Frederick Law Olmsted in the late 1800s as a 1,100 acre chain of parks linked by parkways and waterways.

In the century since the Muddy River was established as a naturalist urban park, it has deteriorated with inflow of toxic heavy metals, petroleum and other pollutants. Currently, a major restoration is planned that would improve flood control and water quality, enhance its aquatic and riparian habitats, restore the landscape and historic resources and implement improved management practices.
