Course Description
ENV4330 is the hazardous waste course in a Florida environmental or civil engineering degree. The Statewide Course Numbering System titles it Hazardous Waste Control and defines it as "rules, regulations and management systems for proper control of hazardous wastes. Evaluation of engineering systems to minimize cost and regulatory problems." The statewide prerequisite is introduction to environmental engineering.
⚠ Note what the statewide definition leads with: rules and regulations. That ordering is correct and is not an accident of drafting. Hazardous waste is the most heavily regulated area of environmental engineering, governed by RCRA Subtitle C — a cradle-to-grave regime with generator categories, manifesting, treatment standards, land disposal restrictions and personal liability provisions that have no equivalent in municipal waste. The engineering only makes sense inside the regulation, and a technically sound solution that is not permittable is not a solution.
Two Florida public universities carry this number, and ⚠ they teach visibly different courses under it:
| Institution | Its title | Credits | What that indicates |
|---|
| Florida International University | Hazardous Waste Site Assessment | 3 | Investigating contaminated sites — sampling, characterisation, remediation |
| University of West Florida | Hazardous Waste Engineering | 3 | Managing waste streams — treatment, storage, disposal, compliance |
Those are related but genuinely different jobs. See the offering notes below before assuming which one your course covers.
Learning Outcomes
Required Outcomes
- Determine whether a material is a hazardous waste under RCRA: the solid waste definition, listed wastes, and the four characteristics — ignitability, corrosivity, reactivity and toxicity.
- Apply the Toxicity Characteristic Leaching Procedure and interpret its result.
- Classify a generator by category and state the obligations that follow — accumulation limits, time limits, training and reporting.
- Explain the cradle-to-grave manifest system and the generator's continuing liability after the waste leaves the site.
- Describe treatment, storage and disposal facility requirements and the permitting that governs them.
- Explain the land disposal restrictions and the treatment standards that must be met before land disposal.
- Describe the principal treatment technologies — physical, chemical, thermal and biological — and select among them for a given waste.
- Explain CERCLA (Superfund), liability under it, the National Priorities List, and how it differs from RCRA.
- Describe contaminant behaviour in the subsurface — transport, retardation, plume development — at a working level.
- Describe site investigation and characterisation: phased assessment, sampling design, monitoring wells.
- Describe remediation technologies — pump and treat, soil vapour extraction, bioremediation, stabilisation, thermal treatment, monitored natural attenuation — and their applicability.
- Conduct a risk assessment appropriate to a contaminated site, and relate it to cleanup target levels.
- Apply waste minimisation and pollution prevention as the first response rather than the last.
Optional Outcomes
- Conduct a Phase I Environmental Site Assessment to the ASTM standard — ⚠ directly employable, and central where the course is titled site assessment.
- Model contaminant fate and transport in groundwater.
- Design a specific remediation system in detail.
- Address brownfields redevelopment and its incentives.
- Address emerging contaminants, notably PFAS.
- Address occupational exposure and HAZWOPER requirements.
- Complete a site assessment or remediation design project.

Resources & Tools
- Hazardous Waste Management by LaGrega, Buckingham and Evans is the standard text for this course and covers both the regulatory and the engineering halves.
- Introduction to Environmental Engineering (Davis and Cornwell) supplies the background where students arrive without it.
- ⚠ Regulation is primary source material, not background reading. Work from 40 CFR Parts 260–268 (RCRA Subtitle C) and 40 CFR Part 300 (the National Contingency Plan) directly, and in Florida from Chapter 62-730 F.A.C. (hazardous waste) and Chapter 62-780 F.A.C. (contaminated site cleanup criteria). All are free online.
- ⚠ Florida's cleanup target levels are in Chapter 62-777 F.A.C. — a table students will use repeatedly and that is genuinely Florida-specific. A national default value is the wrong number here.
- ASTM E1527 — the Phase I Environmental Site Assessment standard, and the document that defines "all appropriate inquiry" for the innocent landowner defence.
- US EPA SW-846 for test methods, and the CLU-IN site for remediation technology guidance.
- The Florida Department of Environmental Protection publishes site cleanup data and the state's contaminated site database — excellent project material.
- Professional bodies: the National Ground Water Association and the Air & Waste Management Association.
Career Pathways
- Environmental Engineer (SOC 17-2081) — site assessment and remediation is one of the largest employment areas in environmental consulting.
- Environmental Scientist or Specialist (SOC 19-2041) — ⚠ and this is the field where geologists, chemists and engineers work side by side, which widens the entry routes.
- Hydrologist (SOC 19-2043).
- Environmental Compliance Officer — generator compliance is steady in-house work at any manufacturing or healthcare employer.
- Health and Safety Engineer (SOC 17-2111).
- Florida employers: the Florida Department of Environmental Protection Division of Waste Management; consultancies doing assessment and remediation (Geosyntec, Tetra Tech, Arcadis, AECOM, Terracon, Universal Engineering Sciences); the petroleum sector, where Florida's programme for leaking underground storage tanks has generated assessment work for decades; defence and aerospace sites along the Space Coast and at Jacksonville, which carry legacy contamination; and the phosphate industry.
- ⚠ Florida's hydrogeology makes this speciality unusually active here. A shallow water table, permeable sandy soils and karst limestone mean contamination reaches groundwater quickly and travels — and the aquifer is the state's drinking water supply. Sites that would be a slow problem elsewhere are an urgent one here, and the regulatory response reflects that.
Special Information
Offering Notes — offerings and hours, school by school
| Institution | Its title | Credits | Contact hours |
|---|
| Florida International University | Hazardous Waste Site Assessment | 3 | not published |
| University of West Florida | Hazardous Waste Engineering | 3 | not published |
Both are State University System institutions, so statewide numbering guarantees transfer of this course between them. ✅ Both carry it at 3 credits.
⚠ The 45 contact hours at the top of this guide are derived — the Florida convention for a 3-credit lecture course. Neither institution publishes an hour figure.
⚠⚠ Site assessment or waste engineering — the two titles point at different work
This is the section to read before registering. The statewide definition covers "rules, regulations and management systems… evaluation of engineering systems", which is broad enough to contain both readings, and the two institutions have each taken one:
- Florida International — "Hazardous Waste Site Assessment." The emphasis is on contaminated land: investigating a site, designing a sampling programme, characterising a plume, assessing risk, and selecting a remedy. This is the consulting-side skill set, and it leans on hydrogeology.
- University of West Florida — "Hazardous Waste Engineering." The emphasis is on waste streams: generator compliance, storage and containment, treatment selection, manifesting and disposal. This is the industry-side and regulator-side skill set, and it leans on process engineering.
⚠ Both are legitimate readings of the number, and both are employable — but they are not interchangeable preparation. A student aiming at environmental consulting wants the assessment version; one aiming at a compliance role in manufacturing or healthcare wants the engineering version. The transcript line will look identical either way, so keep your syllabus: an interviewer asking whether you have done a Phase I is asking a specific question.
⚠ Hazardous waste may also arrive folded into the solid waste course
Florida International titles ENV4351 "Solid and Hazardous Waste Management" — so at that institution some of this material appears in the solid waste course as well. Statewide, the two are separate numbers covering separate regulatory regimes: Subtitle D for municipal solid waste, Subtitle C for hazardous waste, and the second is far more demanding than the first.
⚠ A course covering both in one term covers each less deeply. If you need genuine hazardous waste competence, take this course as well rather than assuming the combined one discharged it.
Position in the curriculum, the FE exam and licensure
A senior-level elective following the introductory environmental engineering course (ENV3001C, ENV3001 or ENV4001). Hydrogeology or groundwater hydrology is a strong advantage and is assumed in places, particularly in the site assessment version.
Hazardous waste and site remediation is a content area on the NCEES PE Environmental examination. The FE is the first step toward Professional Engineer licensure through the Florida Board of Professional Engineers, which requires four years of qualifying experience before the PE examination.
⚠⚠ This is the environmental subject with the most direct personal legal exposure. CERCLA liability is strict, joint and several — a party can be liable without fault and for the whole cost. Site assessment reports are relied upon in property transactions and are litigated. Signing a Phase I is a professional act with consequences that outlast the project, and the course should leave you understanding that before you are asked to do it.
Workload
Budget seven to ten hours a week. The distinctive demand is the reading of regulation. RCRA is genuinely intricate — the definition of solid waste alone has defeated courts — and students accustomed to problem sets find the text slow and then discover that the precision is real and the imprecision was in their reading. ⚠ Learn to navigate the CFR early. Being able to find a provision quickly is the skill, more than memorising any particular rule.
AI Integration
Of all the environmental courses, this is the one where these tools are most dangerous, and the reason is specific: the subject is almost entirely regulation, and regulation is where models fabricate most confidently.
Genuinely useful: explaining a remediation technology's mechanism — how soil vapour extraction works, why a surfactant flush is used; explaining contaminant transport concepts; generating practice problems; summarising a long technical document as a first pass; drafting report prose; and writing spreadsheet routines for transport or risk calculations.
⚠⚠ Where it fails, and the failures here have consequences:
- Fabricated citations. Models produce CFR sections and F.A.C. chapters that do not exist, formatted exactly like real ones. In a field where the citation is the answer, this is not a minor error.
- Superseded rules. RCRA has been amended repeatedly; models quote old generator categories and old thresholds.
- Federal answers to Florida questions. ⚠ Florida runs an authorised state programme and sets its own cleanup target levels in Chapter 62-777 F.A.C. A generated national default is the wrong number, and using it would produce a cleanup that does not close the site.
- Confident treatment recommendations without the waste's actual characterisation — the same error as the geotechnical case: a plausible answer for a typical waste, where the entire discipline exists because wastes are not typical.
The coincidence worth naming: this course exists to teach that the rule text is the authority and a paraphrase is not. A model's confident restatement of a regulation is precisely the artefact the course trains you to distrust — and the discipline is the same whatever the source: open 40 CFR, open the F.A.C. chapter, read the clause, cite it. That takes minutes and it is exactly what a regulator, an opposing expert or a court will do.
Professional and legal weight: reports in this field are sealed by licensed professionals, relied on in property transactions, and read years later by people looking for error. Liability is strict and can attach without fault. The NSPE Code of Ethics requires objective and truthful statements and work within one's competence. ⚠ There is no version of this work in which an unverified generated citation belongs in a document that someone will rely on.
Academic integrity: read your syllabus. Where the course includes a site assessment or regulatory analysis project, instructor policies commonly distinguish drafting from analysis — and a fabricated citation in coursework is treated as seriously here as anywhere in the university.
