1. CE 3231 - Introduction to Environmental Engineering and Science Reading for Next Class: Sections 3.2 & 3.5 O hio N orthern U niversity Introduction Chemistry, Microbiology & Material Balance Water & Air Pollution Env Risk Management Introduction – Air, Water, and Soil Impacts…oh my. What does environmental engineering and science have to do with life anyway? In today’s lecture you will be introduced to the many ways environmental engineering and science benefits society. You will also see where the field of EE&S intersects with all the products we come to rely on and/or appreciate.

2. Lecture 2 Introduction Air, Water, and Soil Impacts & Pick a Product

3. What is Environmental Engineering? Sustainability Green chemistry Alternative energy Smart Development Water Purification Water Quality Air Quality Laws & Regulations Sanitation Solid/Hazardous Waste Soil/Sediment Quality Remediation Greatest medical advance since 1840 (BMJ, January 20, 2007)

4. Def: Environmental Engineering Wikipedia: Application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation and for other organisms, and to remediate polluted sites.

5. Interdisciplinary Nature Engineering elements: – Chemical Engineering (Processes) – Mechanical Engineering (Equipment Design) – Civil/Structural/Geotech Engineering (Facility Design) Science Elements – Physics – Chemistry (Atmospheric,Water) – Biology (microbiology) – Ecology – Geology – Public Health (risk assessment) Social and Political Elements (Laws and Regulations)

6. Key Legislation Chronology of Environmental Laws CAA – Clean Air Act, 1970 WPCA – Water Pollution Control Act, 1972 SDWA – Safe Drinking Water Act, 1974 TSCA – Toxics Substances Control Act, 1976 RCRA – Resources Reservation and Recovery Act, 1976 CWA – Clean Water Act, 1977

7. 3750 BC – first sewer 100 AD – complex water distribution systems and sewers 1850 – link between water and disease 1906 – water filters used to purify water 1970 – Federal agency created to deal with environmental issues Environmental Engineering is an old field of study:

8. Environmental Engineering Project Possibilities Some examples include… Design a scrub stack for a power plant Develop an alternative energy process Design wastewater or water purification system Redevelop brownfields Regulations/policy implementation and enforcement All environmental engineering projects directly impact the health and well-being of people and the environment they live in.
