Reducing Microbial Concentrations with Stormwater Retention Ponds and Constructed Wetlands
Vincent D. Reynolds, MBA, P.E.
Course Outline
This 3 hour course will provide the reader with the practical knowledge of the performance of Stormwater retention ponds and constructed wetlands in reducing microbial concentrations. Environmental protection laws will also be discussed. Case studies are also provided to illustrate to the reader how the information learned has been used on pilot and bench scale studies.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
Learning Objective
At the conclusion of this course, the student would have learned the following:
- The purpose of the Clean Water Act (CWA) 1972;
- Illnesses caused by pathogens;
- Effects of rainstorms on Southern California coasts;
- The recreational water quality microbial criteria for freshwater and seawater;
- The concentration range of fecal coliforms from the National Stormwater Quality Database;
- The two general types of BMPs used to reduce the threat of Stormwater;
- How sunlight can reduce percentages of E. coli;
- Potential contributing factors to inactivation rates of bacteria;
- How to measure the light intensity;
- The inactivation rate due to salinity;
- How Chick’s Law is used; and
- The main mechanism of pollutants removal in constructed wetlands and retention ponds.
Intended Audience and Benefit
This course is intended for environmental engineers, hydrologic\hydraulic engineers, geo-hydrologists, municipal engineers, project managers, and any persons working in civil engineering field or anyone with an interest in Performance of Stormwater Retention Ponds and Constructed Wetlands in Reducing Microbial Concentrations.
Course Introduction
Stormwater runoff is responsible for polluting several bodies of water with pathogens. These pathogens can be the cause of several illnesses when exposed to humans. This course will provide the reader with the study of the fate of indicator organisms in the Stormwater runoff entering and exiting constructed wetlands and retention ponds as performed by The National Risk Management Research Laboratory (NRMRL). Pilot scale studies as well as bench scale studies were performed that represented larger field-scale systems to determine the mechanisms that aid in reducing the indicator organism concentrations.
