circle 2150 1600 100 [[Chloride in stormwater|The primary source of chloride in urban areas is road salt. Chloride concentrations are greatest in winter and in the early phases of snowmelt. Chloride is a mobile contaminant that is easily transported with water. At elevated concentrations it poses risks to aquatic habitats. It can also mobilize metals, inhibit lake mixing, negatively impact vegetation, and damage infrastructure.]] | circle 2150 1600 100 [[Chloride in stormwater|The primary source of chloride in urban areas is road salt.

− | circle 3800 1600 100[[Bacteria|Ultimately the source of bacteria in urban stormwater is animal waste. Identifying the specific source is more challenging and likely varies with location and land use. Typical sources include domestic pets and wildlife, particularly birds. Sources of bacteria to receiving waters include urban stormwater runoff, leaking sewer lines, sewer overflows, septic systems, landfills, marinas and pumpout facilities, poorly operating packing plants, and other illicit discharges.]] | + | circle 3800 1600 100[[Bacteria in stormwater|Ultimately the source of bacteria in urban stormwater is animal waste.

Welcome to the Minnesota Stormwater Manual Table of Contents. The format for this page has changed. If you would like to access the Table of Contents or Main page as they previously existed, use the following links.
The wiki platform provides multiple options for searching topics. You can find out more on the following pages.
The basis for organizing information on this website is the Categories function, which can be accessed in the left toolbar or at this link.
Below are the nine Level 1 Categories, associated Level 2 categories (subcategories), and links to each of them.
