ENHS 340: Environmental Technology and Control

A study guide to UMGC's ENHS 340, which applies technology to prevent, detect, treat and remediate pollution in air, land and water.

Updated October 2026 · 5 min read

ENHS 340 at the University of Maryland Global Campus (UMGC) is an introduction to technology for environmental health and safety management, control and remediation. UMGC lists ENHS 300 as the prerequisite and says credit may be received for only one of ENHS 340 or ENMT 340.

The objective is to apply appropriate technological solutions to air, land and water to prevent, detect, treat and remediate pollution. Students find the challenge is choosing: many technologies could work, and marks go to the one you can defend for the situation.

Waste removal, treatment and disposalThe final stage of managing waste streams

Key Concepts Explained

Matching Technology to the Problem

Start with the contaminant, the medium (air, soil or water), concentration and goal. A method suited to one contaminant or medium may be useless for another.

Example: For a site with petroleum contamination in soil, options might include excavation, in-place biological treatment or vapor extraction. Compare them on effectiveness for that contaminant, time, cost, disruption and residual risk, then recommend one with reasons.

Decision Factors

Typical criteria include effectiveness, cost, regulatory acceptance, time, reliability, energy use and secondary waste. State your criteria and weight them.

Emerging Technologies

New technologies promise much but carry uncertainty. Discuss evidence of performance and acknowledge limits.

Learning the Technologies by Medium

Organize your notes by air, land and water, then by the four actions the catalog names: prevent, detect, treat and remediate.

MediumExample approaches to know
AirFiltration of particles, scrubbing of gases, combustion or adsorption of vapours
LandExcavation, containment, biological treatment, vapor extraction
WaterScreening and settling, biological treatment, filtration, disinfection

Making a Defensible Selection

Weight your criteria before scoring the options. If time is critical, say so and give it more weight; if budget is fixed, do the same. Then show the scores in a table and explain any close calls.

Finish with the residual issues, such as waste to be disposed of, that your chosen technology leaves behind, since the catalog includes removal, treatment and disposal.

Common Mistakes to Fix Before You Submit

Adding one sentence per option on limits and residuals often raises the quality of a recommendation noticeably.

Reading a Prompt and Planning Your Time

Start with the problem statement: contaminant, medium, concentration if known, and goal such as meeting a discharge limit. Then list two or three realistic technologies, not ten. Depth of comparison earns more than a long list.

Reserve time for a short section on monitoring, because the catalog includes detecting pollution as well as treating it. A technology is only as good as your ability to show that it is working.

Detection and Monitoring

Technology is not only about treatment. Detection tools, such as sensors and sampling methods, tell you whether a release is occurring and whether a control is effective.

When you recommend a technology, include how performance will be monitored, how often, and what result would trigger corrective action. This closes the loop between prevention, detection, treatment and remediation, the four actions the catalog names.

How We Help with ENHS 340

Send the prompt, rubric and case details. We can provide a custom analysis, explain the technologies, or review your draft, with sources cited.

The help is for study and reference. It is not engineering advice, not for submission as your own work, and no grade is promised. GradeEssays is independent of the University of Maryland Global Campus. Work is written from scratch and plagiarism-checked, with free revisions within the scope of your original request.
