TYPE OF REPORT AND PERIOD COVERED final 14. SPONSORING AGENCY CODE EPA/ORO The primary types of construction activity which severely impact wetland environments of the United States include: floodplain surfacing and drainage, mining, impoundment canalization, dredging and channelization, and bank and shoreline constructton. Each type of construction activity is attended by an identifiable suite of physical and c ' ( J-' ;C ~ c --:c chemical alterations of the wetland environment which may extend for many miles from 1 ~C the site of construction and may persist for many years. In turn, each type of physical and chemical modification has been shown to induce a derived set of biologi- cal effects, many of which are predictable, in general, if not in specific detail. The most environmentally damaging effects of construction activities in wetland areas, in order of ·importance, are:· direct habitat loss, addition of suspended solid~ ''· and modification of water levels and flow regimes. Major construction-related impact~ c a 1 so derive from a 1 tered water temperature, pH, nutrient 1 eve 1 s, oxygen, carbon di.ox- ide, hydrogen sulfide, and certain pollutants such as heavy metals, radioactive isotopes, and pesticides. c 17.
