Ai Ceti <br />AScI Corporation <br />6201 Congdon Boulevard. Duluth, Minnesota 55804 <br />Mr. William Sanders <br />Little Canada City Council <br />Sanders and Associates, Inc. <br />365 E. Kellogg Blvd. <br />St. Paul, MN 55101 <br />March 10, 1989 <br />Dear Mr. Sanders and Councilors: <br />13 <br />In our March 9 phone conversation, you requested an overview <br />of the AScI wetlands project. <br />Our organization, in cooperation with the U.S. Environmental <br />Protection Agency laboratory based in Duluth and the Natural <br />Resources Research Institute of UM- Duluth is conducting a <br />wetlands water quality study. We are focusing on the seven <br />county metro area and Wright Co. The purpose of our study is to <br />determine the effects of different types of disturbances, such as <br />draining, filling, stormwater inputs, wastewater inputs, and <br />erosion on the water quality and "health" of downstream wetlands. <br />This work is part of a national program assessing the "health" of <br />the nation's wetlands. The information obtained from individual <br />wetland sites will not be analyzed singly, but will be integrated <br />with data from many other similar wetlands being subjected to the <br />same type of disturbance. <br />Our research plan calls for us to identify wetlands at which <br />permits are in effect or being obtained for some type of activity <br />that may impact the wetland. We are seeking sites that represent <br />a range of wetland types including marsh, wooded, steamside, lake <br />fringe, and wet meadow. We sample these sites prior to the <br />disturbance and several times during and after the disturbance <br />takes place. Sampling takes approximately an hour every other <br />month and involves collecting a surface water sample and taking <br />simple chemical, hydrologic and biologic measurements. <br />We did some preliminary sampling at many sites last fall and <br />will continue water and sediment sampling as soon as open water <br />is available this spring. At present, we are working on about 35 <br />sites. <br />We request permission to sample the wetland (Ramsey - <br />Washington Metro Watershed District wetland GL39) immediately to <br />the east of the proposed Centerville Road Park in Little Canada, <br />and to sample Ramsey Co. ditch 16 north of the park area.
