博士 只有获得足够的高学历证据和从事环境工程领域独立研究的能力，才能授予学位。博士 与MS学位相比，该学位的研究重得多，并且旨在成功地掌握一些技能和知识，为独立学者的职业做准备。该学位推荐给那些希望从事高级研究，教学或技术工作的专业人士。博士 候选人必须至少获得12个小时的论文学分，并撰写证明对所选主题的最新技术有重大贡献的论文。博士 论文委员会必须比MS委员会包括更多的成员，并且必须至少包括一名外部成员。博士学位有居住要求。学生必须获得合格的考试和学位论文建议辩护才能获得博士学位。程序。
The Ph.D. degree is awarded only upon sufficient evidence of high attainment in scholarship and the ability to engage in independent research in the field of environmental engineering. The Ph.D. degree is substantially heavier in research compared with the M.S. degree and is geared towards successfully mastering a body of skills and knowledge in preparation for a career as an independent scholar. This degree is recommended for those who expect to engage in a professional career in research, teaching, or technical work of an advanced nature. Environmental engineers in the department are actively researching the fate and impact of pharmaceuticals in wastewater, analysis and remediation of toxic pollutants in soils and other environments, the processes governing atmospheric chemistry and aerosol pollution, and advanced real-time modeling and monitoring of groundwater-surface water conditions.
