Assess the impact of industrial and hazardous waste on human populations. Reading Assignment Chapter 1: Wastewater Treatment Unit Lesson As you will notice, this class is designated as MEE (Masters of Environmental Engineering). As scholar- practitioners of environmental management, it is imperative that we learn to apply engineering principles to keep the environment and other people as safe as possible while operating within work systems across a wide cross-section of industry settings. This is the very basis for studying environmental engineering. Environmental managers typically observe and report incidents while implementing administrative programs to hopefully reduce the volume of incidents experienced in a given industry setting.

Environmental engineers do something different. First, environmental engineers study the affected work systems to identify independent variables causally related to incidents. Second, environmental engineers use statistical data analysis to forecast future incidents. Finally, environmental engineers work to engineer out the risks from the work system. All of this is done well before introducing the environment and humans into the contemporary work system.

This is the very work that we must do as scholar-practitioners of environmental management. Consequently, we must learn to think and work as environmental engineers. This unit is going to help us focus on our objectives for this entire class as we learn to study industrial and hazardous waste systems with the most effective technical design tools available to the environmental engineering field. Let’s make the mental transition from an environmental manager to an environmental engineer together as we begin! First, in an effort to appreciate the need for properly managing these wastes, it is important for us to assess the impact of industrial and hazardous waste on human populations.

Hickman (2003) explained that the United States only began understanding the impact of solid, industrial, and hazardous waste on the human population after World War II (late 1950s). Before the early 1970s, the larger part of waste management seemed to have been focused on the transportation of the wastes, rather than the treatment and subsequent disposal of the wastes (Hickman, 2003). By the time we reached the early 1980s, we had just begun to recognize the relationship between the industry type standard industrial code (SIC) and the waste types (classifications) largely associated with each industry. For example, we learned that roughly 70% of the hazardous waste nationwide was generated by the chemical industry (SIC code 28), with approximately 20% belonging to the primary metals industry (SIC code 33), and the remaining 10% belonging to the additional industry types (Haas & Vamos, 1995).

Still, one of the most informative realizations was that approximately 90% of the waste was being generated by approximately 10% of the waste generators among industry types. As such, one of the first classifications that is important for us to understand is the small UNIT I STUDY GUIDE Industrial Hazardous Waste Attributes, Impacts, and Regulations MEE 5801, Industrial and Hazardous Waste Management 2 UNIT x STUDY GUIDE Title quantity generator that represents the 90% of the industry generators producing approximately only 10% of the total waste (Haas & Vamos, 1995). Second, given that we understand every process is likely to have an effluent waste stream (solid, liquid, or gas), it is imperative that we as environmental engineers understand the waste aspect of a given operation.

This means we must learn the fundamental science (chemistry and physics) and engineering principles involved in the operation. Interestingly, the majority of the chemistry involved in waste treatment occurs within the wastewater matrices of the industrial effluents. Bahadori (2014) carefully navigates us through this critical first lesson of wastewater chemistry within the context of a wastewater treatment plant. It is critical that you take the time to carefully follow Bahadori (2014) through this discussion as it will inform your thinking throughout the entire course. Third, it is important that we be able classify wastes by understanding and recognizing the key attributes of wastes that may be considered industrial wastes, solid wastes, or hazardous wastes.

In addition to Bahadori’s (2014) characterization and classification of wastewaters, we must also begin to recognize the differences between solid wastes and hazardous wastes generated by industrial sources. This is largely achieved by using applied chemistry to delineate the differences between solid wastes and hazardous wastes. We first distinguish between inorganic wastes and organic wastes. Then, we further segregate by type: (inorganics) acid wastes, alkaline wastes, and other inorganic wastes; (organics) concentrated liquids, dilute aqueous solutions, organic solids, and organic gases/vapors. Everything else not falling in either of these categories (such as biological wastes, explosives, strong oxidizers, and strong reducers) is considered a special waste (Haas & Vamos, 1995).These chemical and physical attributes are recognized only through chemical and physical laboratory testing with Environmental Protection Agency (EPA) approved test methods.

Finally, we must consider the relevant laws, standards, and best practices related to managing these wastes. While there are local municipal and state laws governing specific aspects of waste management and disposal (often termed local limits), the EPA ultimately governs the most contemporary and best practices through several laws (e.g., Clean Water Act, Clean Air Act, Resource Conservation & Recovery Act [RCRA]). Additionally, the EPA governs with the Code of Federal Regulation (CFR) (specifically 40 CFR Part 261 for RCRA hazardous waste identification and 40 CFR Part 503 for sewage sludge) (Haas & Vamos, 1995). As we progress through this class, we are going to be designing a waste management system within the context of a course project.

This course project will be a proposed industrial and hazardous waste treatment facility that we will individually engineer, complete with wastewater, solid, and gas treatment and control technologies. As such, we will draw heavily upon each chapter of Bahadori’s (2014) textbook as we engineer one aspect of the facility design proposal in each unit. This may be your first opportunity to design as an environmental engineer. Take in everything that you can in this class and think like a designing environmental engineer! This is what we are called to do as scholar-practitioners of environmental management.

The city currently accepts liquid wastes from three significant industrial users (SIU): (a) a petroleum refinery, (b) an animal rendering plant, and (c) a tanker truck washout. In an effort to capture revenue, the city is currently accepting the liquid waste physically hauled by tanker truck from all three SIU members and is subsequently collecting the liquid wastes into a 300,000 gallon storage tank, pending your facility design. The city wants to be able to effectively treat and neutralize the liquid waste, landfill or reuse the sludge in an agriculture application, and discharge the neutralized treatment plant effluent water to the existing municipal (residential) wastewater plant for final treatment after successfully meeting the local limits for each analyte.

Introduction

The management of industrial and hazardous waste is a critical aspect of environmental engineering and management. This paper discusses relevant laws and standards for hazardous waste management, the impact of industrial waste on human populations, priority pollutant categories, and the relationship between biochemical oxygen demand (BOD) and suspended solids in wastewater treatment. Understanding these concepts is vital for future environmental managers and engineers as they work to mitigate the adverse effects of waste on public health and the environment.

Relevant Laws and Standards

In the United States, several key laws and regulations govern industrial and hazardous waste management. The main legislative frameworks include the Resource Conservation and Recovery Act (RCRA), the Clean Water Act (CWA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
The RCRA, enacted in 1976, is the primary federal law governing the disposal of solid waste and hazardous waste (EPA, 2023). It establishes a system for tracking hazardous waste from its creation to its disposal, including mandatory laboratory testing procedures to classify waste. The analytical methods prescribed include the Toxicity Characteristic Leaching Procedure (TCLP) and other standardized tests recognized by the Environmental Protection Agency (EPA) that help distinguish hazardous from non-hazardous waste (Haas & Vamos, 1995).
The CWA regulates discharges of pollutants into U.S. waters and sets water quality standards for surface waters. The National Pollutant Discharge Elimination System (NPDES) permits control the discharge of pollutants to ensure they meet federal and state standards (EPA, 2023).
Finally, CERCLA involves the cleanup of hazardous waste sites and is designed to respond to releases of hazardous substances that may pose a risk to human health or the environment (Hickman, 2003). These laws, together with their associated regulations, ensure that best practices in the management and disposal of industrial and hazardous waste are followed, including rigorous laboratory testing to identify waste attributes.

Impact of Industrial and Hazardous Waste on Human Populations

The impacts of industrial and hazardous waste on human populations can be profound and wide-ranging. Exposure to hazardous waste is associated with numerous health risks, including respiratory illnesses, skin conditions, neurological disorders, and even an increased risk of cancers (Lee et al., 2021). For instance, hazardous substances such as heavy metals, solvents, and petroleum hydrocarbons can contaminate soil and groundwater, which may in turn affect drinking water supplies (Hashemi et al., 2014).
Populations residing near industrial facilities or hazardous waste sites are often disproportionately affected due to proximity to these wastes (Sierra et al., 2016). Vulnerable groups, including low-income residents and communities of color, may face greater risks due to a lack of adequate regulatory protections, resources, and access to healthcare. Moreover, there are often social and economic burdens resulting from industrial contamination, such as devaluation of property and increased healthcare costs for affected families (Levin et al., 2020).
Public awareness of the risks associated with hazardous waste, combined with ongoing community advocacy, is crucial for implementing policies that protect human health. The recognition of these impacts is fundamental to the role of environmental engineers who strive to design safer waste management solutions.

Priority Pollutant Categories and Concerns

The U.S. EPA identifies several priority pollutants that pose significant risks to human health and the environment. These pollutants are grouped into specific categories, and select examples include:
1. Heavy Metals: Cadmium (Cd)
- Concern: Cadmium exposure can lead to kidney dysfunction and bone weakening (Baker, 2020).
2. Organic Compounds: Benzene
- Concern: Benzene is recognized as a carcinogen and can lead to blood disorders (IARC, 2018).
3. Nutrients: Phosphorus
- Concern: Excess phosphorus can lead to eutrophication, resulting in the depletion of oxygen in water bodies that harms aquatic life (Carpenter et al., 1998).
4. Pathogens: E. coli
- Concern: Presence of E. coli in water indicates fecal contamination and poses health risks through waterborne diseases (WHO, 2014).
5. Volatile Organic Compounds (VOCs): Trichloroethylene (TCE)
- Concern: TCE exposure is linked to neurological effects and potential carcinogenicity (U.S. EPA, 2021).
Each of these categories is critical in evaluating the health and environmental risks associated with industrial waste and necessitates effective management strategies.

Relationship Between BOD and Suspended Solids in Wastewater Treatment

Biochemical Oxygen Demand (BOD) and suspended solids are two crucial metrics in wastewater treatment. BOD measures the amount of oxygen required by microorganisms to break down organic material present in wastewater over a specified period. High BOD levels generally indicate the existence of a significant amount of organic matter, which can lead to oxygen depletion in water bodies and harm aquatic life (Metcalf & Eddy, 2014).
Suspended solids, on the other hand, refer to particulate matter (both organic and inorganic) that remains in suspension in wastewater and is not dissolved. A higher concentration of suspended solids can affect the efficiency of biological treatment processes by providing habitat for microorganisms, but excessive amounts can hinder treatment due to fouling of equipment (Tchobanoglous et al., 2014).
The relationship between BOD and suspended solids is integral to efficient wastewater treatment. Typically, high levels of suspended solids correlate with high BOD, indicating a high organic load. Therefore, effective treatment requires a balance between removing suspended solids and reducing BOD (Hassan et al., 2022). This process typically involves primary (physical) and tertiary (chemical and biological) treatment stages to ensure both metrics are adequately controlled before discharge into the environment.

Conclusion

Understanding the complexities of industrial and hazardous waste management is essential for future environmental engineers and managers. By recognizing and adhering to relevant regulations, appreciating the significant human health impacts, identifying priority pollutants, and understanding critical metrics such as BOD and suspended solids, we can enhance our approaches to waste management. The ultimate goal is to protect human health and the environment while improving sustainability practices in industrial operations.
