He showed results of the impressive study conducted by the GSA in Covington County, where GSA scientists measured  sediment load in several streams before and after installation of BMPs (best  management practices) on dirt roads that crossed the local streams. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/blog.auburn.edu\/aww\/wp-content\/uploads\/2009\/12\/100-3584b.jpg\" width=\"300\" height=\"225\" hspace=\"80\" border=\"1\" \/><\/p>\n<h4 align=\"center\"><a href=\"http:\/\/blog.auburn.edu\/aww\/wp-content\/uploads\/2010\/01\/mcook.ppt\">PowerPoint Presentation<\/a><\/h4>\n<h4 align=\"center\">Video: <a href=\"http:\/\/www.youtube.com\/watch?v=jq4PL7rqsWk&amp;feature=channel\">Part 1,<\/a>\u00a0 <a href=\"http:\/\/www.youtube.com\/watch?v=unXHzB6vkHw&amp;feature=channel\">Part 2 <\/a><\/h4>\n<p align=\"center\">&#160; <\/p>\n<p>The BMPs  included chip-seal (surfacing with tar and limestone) of the road surface from  hilltop to hilltop on both sides of a bridge, armoring drainage ditches along  the sides of the road with limestone rip-rap, installation of curb and gutters,  planting of vegetative cover on road sides, and check-dam installation in  roadside ditches. Mr. Cook emphasized that a relatively small amount of road  improvement on unpaved roads can make a dramatic improvement in stream water  quality (manifest as reduction of dirt being washed into the stream during rain  events) if the improvements are targeted to areas of high erosion at stream  crossings. Results of the GSA study indicated reductions from 46% to 99% in  sediment loads in streams, depending on the BMP treatments installed. The  seminar closed with a stimulating discussion about things that could be done on  Lee County&rsquo;s 187 miles of unpaved roads to  reduce the amount of dirt flushed into our local streams and improve their  water quality. <\/p>\n<p>SWaMP  is administered and coordinated by Alabama Water Watch and Auburn University  Fisheries Department, and partially funded by the Alabama Department of Environmental  Management through a Clean Water Act Section 319(h) nonpoint source grant  provided by the U.S. Environmental Protection Agency-Region 4.<\/p>\n<p style=\"text-align:justify\">Special thanks to Mr. Marlon Cook for traveling to Auburn University  and sharing his knowledge and experiences with us in an effort to restore and  preserve Auburn&rsquo;s  natural resources!<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The SWaMP (Saugahatchee Watershed Management Plan) Project and \u00a0Alabama Water Watch were extremely pleased to have Marlon Cook, Director, Groundwater Assessment Program, Geological Survey of Alabama, present results from a [&hellip;]<\/p>\n","protected":false},"author":6,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-120","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/posts\/120","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/comments?post=120"}],"version-history":[{"count":1,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/posts\/120\/revisions"}],"predecessor-version":[{"id":7769,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/posts\/120\/revisions\/7769"}],"wp:attachment":[{"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/media?parent=120"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/categories?post=120"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aaes.auburn.edu\/wrc\/wp-json\/wp\/v2\/tags?post=120"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
