− | circle 100 500 30 [[Total Suspended Solids (TSS)|Total suspended solids, or sediment, originate from many sources including the erosion of pervious surfaces and dust, litter and other particles deposited on impervious surfaces from human activities and the atmosphere. Erosion at construction sites are also major sources of solids. Solids contribute to many water quality, habitat and aesthetic problems in urban waterways. Elevated levels of solids increase turbidity, reduce the penetration of light at depth within the water column, and limit the growth of desirable aquatic plants. Solids that settle out as bottom deposits contribute to sedimentation and can alter and eventually destroy habitat for fish and bottom-dwelling organisms. Solids also provide a medium for the accumulation, transport and storage of other pollutants including nutrients and metals.]] | + | circle 100 500 30 [[Total Suspended Solids (TSS) in stormwater|Total suspended solids, or sediment, originate from many sources including the erosion of pervious surfaces and dust, litter and other particles deposited on impervious surfaces from human activities and the atmosphere.

circle 1800 500 100 [[Chemicals of emerging concern in stormwater|Chemicals of emerging concern includes a wide range and large number of chemicals whose impacts to human and aquatic health are generally poorly understood. Examples include but are not limited to pharmaceuticals, industrial chemicals, pesticides, fire retardants, microplastics, and cosmetics. Stormwater conveys these chemicals to receiving waters. The behavior of most of these chemicals in the environment is poorly understood.]] | circle 1800 500 100 [[Chemicals of emerging concern in stormwater|Chemicals of emerging concern includes a wide range and large number of chemicals whose impacts to human and aquatic health are generally poorly understood.

circle 2800 500 100 [[Temperature in stormwater|Temperature is a concern in receiving waters when stormwater runoff from hot surfaces enters the receiving water. This occurs in summer on pavements in close proximity to receiving waters, or when constructed ponds discharge warm water to receiving waters. Temperature impacts are typically limited to sensitive species such as trout.]] | circle 2800 500 100 [[Temperature in stormwater|Temperature is a concern in receiving waters when stormwater runoff from hot surfaces enters the receiving water.

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.
