You can find articles on the environment everywhere, including in most issues of the Providence Business Journal. Recently Robert W. Varney, regional administrator of EPA's New England office in Boston, wrote a guest column, "Honoring a legacy by protecting valuable wetlands." The legacy is Rachel Carson's ~ she would have been 100 in May ~ and the wetlands would be the "Borderlands....the largest ecologically intact forested system between Boston and Washington, D.C.," located on the Connecticut and Rhode Island border in South County.
The Borderlands project is described in a 2003 RI DEM report, "South County Greenspace Protection Strategy." It takes a while to open because it's 69 pages long. The Borderlands wetlands help ensure clean drinking water and reduce the impact of storm floods, and in particular, it protects the underlying aquifer which is an important source of drinking water.
