Street Dirt: A Better Way of Measuring BMP Effectiveness

COURSE DESCRIPTION

Stormwater programs have spent (and will spend) millions of dollars characterizing discharges from stormwater outfalls, and yet the complexity and limitations persist. There must be a better way to measure BMP effectiveness.

There is! Join international stormwater quality expert Roger Sutherland to explore a radically different and more effective means to measure BMP effect and progress—street dirt.

In this webcast, we’ll discuss how studying the change in street dirt chemistry is more effective in measuring BMP effectiveness than outfall monitoring. We’ll begin our discussion with the material itself, including its physical and chemical characteristics, its sources, and its source controls. We’ll discuss the traditional challenges and shortcomings of discharge outfall monitoring, and compare the study of the change in street dirt chemistry in terms of effectiveness, limitations, cost, and complexity and identify the advantages. Additionally, we’ll explore street dirt monitoring, sampling and analysis, how easy and inexpensive it is, and identify the best management practices for progress monitoring via street dirt collection, including the necessary equipment. Finally, we’ll explore the growing body of evidence that demonstrates that street dirt (not outfall monitoring) is the better way of measuring BMP effectiveness.

Learning Objectives 
Attendees can expect the discussion and education of the following learning objectives:

  • Learn about the shortcomings associated with discharge outfall monitoring as the traditional way of measuring best management practice (BMP) effectiveness.
  • Review the important physical and chemical characteristic associated with the contaminated sediment like material called street dirt that accumulates on urban highways, streets, driveways, and parking lots.
  • Explore the known sources of street dirt contamination and how the successful control of these sources through targeted BMPs are reflected in the chemistry of the street dirt.
  • Learn about the advantages of using street dirt chemistry as an indicator of change and historic examples of how it has already been used.
  • Identify the management practices and activities that are the most amenable to progress monitoring via street dirt collection along with the typical pollutants that are targeted.
  • Review the history of street dirt monitoring and the established street dirt sampling and analytical procedures including a complete list of the necessary equipment.
  • Learn what we know and don’t know about street dirt chemistry.
  • Review the growing body of evidence that demonstrates street dirt not outfall monitoring is a better way of measuring BMP effectiveness.

* Presentations are scheduled for approximately one hour with a 15-20 minute question and answer session to follow. Presentation may exceed scheduled time. 
* Each state and certification agency has different requirements; it is your responsibility to know what they are. Note that 1 PDH = 0.1 CEU.
