Since 2009, the Center has been providing high quality webcasts for stormwater and watershed professionals. Over the past six years, an estimated 20,000 professionals have participated in the Center’s webcasts.

Newly recognized contaminants of emerging concern (CECs) include a broad list of synthetic or naturally occurring chemicals (e.g., pharmaceuticals, synthetic fragrances, detergents, disinfectants, plasticizers, preservatives) or any microorganisms that have the potential to cause adverse ecological and(or) human health effects. Advances in our ability to detect and study CECs in the environment have shown that they are widespread throughout the aquatic ecosystem, and some studies are showing adverse impacts to aquatic organisms and public health. While a major source of CECs is POWT discharges, illicit discharges containing sewage into the municipal separate sewer system is a major pathway for CECs to be delivered to urban and suburban stream systems. Illicit discharge detection and elimination (IDDE) systems have the potential to be effective tools to mitigate the effect of CECs on the environment. This webcast focuses on CECs and the potential for IDDE programs to reduce their impacts.

Nutrient credit trading offers both risks and opportunities for meeting total maximum daily load (TMDL) nutrient reduction targets. Some states have established nutrient trading or offset programs, with most current trades involving wastewater treatment plants and limited involvement from the stormwater sector. In this webcast, we will look at the increasing exploration of nutrient trading, review case studies of trading programs, and discuss the future of nutrient trading in meeting pollution reduction regulations.

The water quality benefits of forests are widely accepted, yet very few studies have successfully quantified the runoff and pollutant-reducing impacts of trees in the urban landscape. Using everything from individual street trees up to small patches of forest as a stormwater best management practice (BMP) is hampered by this uncertainty of how to “credit” urban trees for runoff and pollutant load reduction. This webcast will review the available stormwater crediting systems for urban tree planting and will present a new crediting system that includes a design specification for urban tree planting that can be integrated into state and local compliance systems for stormwater management, TMDLs and other water quality requirements.

Stream restoration has been used for many years for various objectives, including pollutant reduction requirements for TMDL compliance. But the use of stream restoration practices to effectively achieve required nutrient and sediment reductions has been a topic of debate in the scientific community. Recent efforts by an advisory panel to the Chesapeake Bay Program reviewed the latest available science to quantify the various benefits of stream restoration and develop a methodology to document that stream restoration projects are helping them to meet their TMDL targets. In this webcast we will examine the expert panel recommendations and discuss the role of stream restoration in meeting water quality goals and also discuss the results of WERF’s National Stream Restoration as a BMP Guidance.

Published in 1998 as a consensus-based process for changing development regulations, the Center’s Better Site Design Handbook outlines 22 model development principles for site design that act to reduce impervious cover, conserve open space, manage stormwater at new residential and commercial development sites; and reduce the overall cost of development. Much has happened in the world of stormwater and site planning in the 18 years since the release of the handbook, including technical and regulatory advances that have changed how stormwater is managed and sites are developed. To respond this need, the Center recently revised the handbook and related support products to reflect the latest in stormwater management technology and regulations such as MS4 permits, provide different versions of the COW for different site situations, update the supporting research, case studies, model code/ordinance library and more!

Modeling is frequently used in watershed and stormwater planning to help build understanding of a problem or calculate possible changes over time when monitoring is not an option. Modeling can also be used to compare courses of action to determine effective strategies for addressing a problem and the potential cost for each strategy. Non-point source modeling tools are an important tool in estimating compliance with TMDL allocations and developing an overall watershed plan to meet water quality. In this webcast we will look at several tools for estimating pollutant loads, discuss the possible applications, and look at case studies to illustrate how a model was employed to achieve the desired goals.
