Wastewater

Environmental Engineering, Water & Wastewater (Sixth Edition)

Updated and reviewed by leading experts in the field, this revised edition offers new coverage of industrial solid wastes utilization and disposal, the use of surveying in environmental engineering and land use planning, and environmental assessment. Stressing the practicality and appropriateness of treatment, the sixth edition provides realistic solutions for the practicing public health official or environmental engineer.

The Florida Onsite Sewage Nitrogen Reduction Strategies Study: Project Overview

In recent years, nitrogen in the environment has become a nationwide concern due to the sensitivity of many water bodies to excess nitrogen loading from many different sources, including Onsite Wastewater Systems (OWS). This session will kick off an afternoon of sessions that highlight recent research sponsored by the Florida Department of Health which is being used to develop strategies to manage and reduce nitrogen loading from OWS and to protect groundwater and surface waters.

Reduction of Nitrogen from OWS: Performance of In-ground Systems

The Florida Onsite Sewage Nitrogen Reduction Strategies Study evaluation of nitrogen reduction options for OWS was followed by the development and testing of pilot-scale passive nitrogen reduction systems (PNRS). Initial encouraging results led to the design, construction, operation and monitoring of several full-scale PNRS at homes in Florida. This presentation focuses on the results from the monitoring of the in-ground systems. The design, construction, performance, operation, and maintenance of these systems will be discussed.

Quantifying Rates of Denitrification in the Biozone and Shallow Subsurface

In recent years nitrogen in the environment has become a nationwide concern due to the sensitivity of many water bodies to excess nitrogen loading from many different sources, including Onsite Wastewater Systems (OWS). Complimentary to the Florida Onsite Sewage Nitrogen Reduction Strategies study, the Colorado School of Mines evaluated denitrification via subsurface via a soil treatment unit (STU). This presentation will share the rates of denitrification achieved and how to substantially increase them.

Protecting, Conserving, Reclaiming and Reusing the Water that Gives Us Life

This presentation will use Walt Disney World as a large scale example to discuss and explore the problems and pitfalls that befall water systems as they serve to provide access to clean safe water, promote responsible water use, and promote the reuse of fresh and wastewater. Compare what is required in current codes and industry standards to the programs being used in Reedy Creek Improvement District of Florida. Leave with an understanding of the synergy between EH and water conservation practices.

Reduction of Nitrogen from OWS: Performance of Tank-Based Systems

The Florida Onsite Sewage Nitrogen Reduction Strategies Study evaluation of nitrogen reduction options for OWS was followed by the development and testing of pilot-scale passive nitrogen reduction systems (PNRS). Initial encouraging results led to the design, construction, operation and monitoring of several full-scale PNRS at homes in Florida. This presentation focuses on the results from the monitoring of the tank-based systems. The design, construction, performance, operation, and maintenance of these systems will be discussed.

Power To The People: How EH Professionals Can Help Communities Help Themselves

From 2003-2010, the Water Environment Research Foundation administered an $8 million USEPA-ORD grant which identified the need to educate small community elected and appointed officials on sanitation systems. A comprehensive tool called “Wastewater Basics for Small Community Leaders and Planners” was published, but insufficient funding to publicize and implement it has kept it unknown to many. This presentation will share the document and guide attendees in its use and application as an effective tool in education and resource management.

Onsite Wastewater Treatment System Nitrogen Contributions to Water Resources in North Carolina

Elevated nitrogen concentrations in groundwater and surface waters are a health and environmental concern. The presenters monitored concentrations of nitrogen in groundwater at sites that use onsite wastewater systems (OWS), in surface waters, and in deeper groundwater near the systems to determine the OWS nitrogen contributions. They’ll describe the monitoring techniques and results to provide attendees with a holistic understanding of the role of the OWS in the nitrogen cycle and possible approaches to watershed nutrient management plans.
