Water is a critical resource that must be protected to supply safe drinking water and support various activities, such as farming, manufacturing, and tourism. The federal Clean Water Act (CWA) protects waters of the United States (WOTUS). This ½ hour online training course provides general guidance on what waters are considered WOTUS.
With certain exceptions, the CWA prohibits the discharge of pollutants from a point source into waters of the United States without a National Pollution Discharge Elimination System (NPDES) permit. The requirements of this permit are also covered in this training course.
Historically, wastewater treatment started as risk reduction for human health and welfare, migrated to environmental risk reduction, and has now matured into resource recovery and revenue generation. Technology and common practices are in place to treat water as a sustainable resource; we simply can no longer afford to use it once and “throw it in the ocean” nor can we afford the liability of not treating water to our best abilities to protect human health and the environment. In this interactive online course, we will cover specifics, metrics, and detailed examples about recovery of the water from wastewater.
We discuss how to manage the design of wastewater facilities to reduce environmental, personal, and public health risk from insufficiently treated potable and reuse water supplies. We will also show how to reduce costs in operation of a proper wastewater treatment plant.
The treatment of wastewater is an important process that eliminates potentially harmful waste from entering our environment. When used effectively, land treatment systems can safely treat wastewater before it enters our ground water. This 1 hour interactive online course addresses operation and maintenance of the three types of land treatment systems, slow rate, overland flow, and rapid infiltration, and discusses how they differ in the rate that water is applied. All three land treatment systems use vegetation and soil percolation as methods to treat wastewater. Each type of system is used as each situation warrants.
This course may be used to prepare additional operations and maintenance manuals, providing valuable information that may be used to understand the operation and maintenance of land treatment systems. At the conclusion of this course, you will be armed with all the knowledge and skills to design basic land treatment systems and to further your study in this important field.
Hazardous waste can exist in liquid, solid or slurry forms. It may originate in a current manufacturing process or from clean-up of an abandoned site. This course will review the background and design considerations for different methods of treating hazardous waste.
Onsite wastewater treatment systems enable millions of people who do not have access to public sewage and treatment plants to treat household effluent by safely cleansing the wastewater and returning it to the environment. However, faulty treatment systems can contaminate the surrounding environment, spreading contaminants and disease that may pollute groundwater reservoirs for generations.
This 4 hour interactive online course is based on Chapter 2: Management of Onsite Wastewater Treatment Systems, from the Environmental Protection Agency’s Onsite Wastewater Treatment Systems Manual. This chapter is intended as an informational guide to management of these systems, a key element in maintaining the health of the public and the environment.
Many households live in rural areas that do not have access to public water or sewer systems.

Many industrial processes, including the production of pulp, paper, and board products, require large volumes of water. Governments require these facilities to collect and treat their effluent streams in order to protect the environment. The sewer and effluent system is responsible for collecting all of the effluents present on site, which may include process effluent, sanitary effluent, and surface water runoff effluent. This module describes process sewers and effluent collection systems and the purpose of primary, secondary, and tertiary effluent treatments.
It’s understood that drinking water should be suitable for human consumption and for all usual domestic purposes. So, what is suitable drinking water? Ideally, drinking water should not contain any microorganisms known to be pathogenic or capable of causing diseases. It should be free from chemical contamination, and it should have the right physical properties.
In this interactive, online course, we will discuss key information regarding drinking water monitoring and security required to ensure the health, safety, and welfare of the general population being served by water supply facilities. We will discuss the minimum parameters recommended for monitoring drinking water, and the surveillance process and products used for monitoring water quality. We will also discuss the types of threats to facilities, and types of physical security elements that may be put into place to help protect these facilities.

This training module focuses on these regulations and the operator’s role in controlling industrial pollution.
Pulp bleaching is usually accomplished using a series of chemical treatments. The chemicals and the order in which they are used make up a “bleaching sequence.” One of the main goals of bleaching is to mitigate the environmental impact it has on the environment. This ½ hour online training course will focus on the environmental concerns associated with pulp bleaching including water and energy use, resource conservation, air emissions, and wastewater quality.
Approximately 40% of the world’s drinking water is drawn from wells, and in some locations, like in the Pacific Southwest, 80% of potable water is drawn from aquifers. Groundwater is an easily accessible resource, and this accessibility is also its biggest threat. Contaminants above ground and underground can easily seep into aquifers.
There are a large variety of contamination sources, both natural and man-made. Similarly, there are a wide variety of remediation techniques to properly treat contaminated aquifers. Throughout this course, engineers, architects, planners and contractors will learn about the most common contamination sources and the industry best practices used for groundwater aquifer remediation.
Lead contamination of drinking water is a major topic of concern across the country, particularly in areas with aging lead pipes. Lead contamination in Flint, Michigan; Washington, DC; and Newark, New Jersey, has focused attention on America’s decaying pipes.
At least $384 billion of improvements are needed to maintain and replace essential parts of the country’s water infrastructure to through 2030, according to the US Environmental Protection Agency. While these improvements are underway, treatment technologies can be utilized to significantly limit the migration of lead into the potable water supply. This interactive online course will describe these technologies and opportunities for implementation.
The tool allows users to build a plant, select contaminants and observe emissions. Toxchem is mainly used for estimating VOC air emissions from wastewater collection, preliminary / primary / secondary treatment and disposal facilities. The site specific wastewater characteristics, contaminant properties and the process design and operating information are used to estimate VOC emission rates.
In addition to air emission estimates, Toxchem can also be used to estimate the concentrations / loads of contaminants in the water effluent, or oil and residual solids streams.
Toxchem is based on fundamental mass transfer equations and mass balances including the removal mechanism of stripping and volatilization, biodegradation and sorption. Thus, it can also be used to determine the fate of any synthetic chemical compounds for which the physical, chemical and biodegrading properties are known.
Typical applications could be in assessing the fate of chemicals for the REACH legislations in EU or studying the fate of Endocrine Disrupting Compounds in wastewater treatment plants.
