Textbook: Groundwater and Wells by Driscoll, F.G. 2nd Edition, Johnson Filtration Systems, 1989. ISBN: 0961645601


Catalog Description: Well Hydraulics and DevelopmentThe theory and methods of well installation, testing, and the design, construction and maintenance of well systems. Hydrogeologic and geophysical techniques in groundwater exploration; development of groundwater resources by well drilling, well design and safe yield determination.  Analysis of single and multiple well aquifer tests in a range of hydrogeologic environments (confined, unconfined, leaky-confined, and fractured aquifers. Theory and practice of conducting and analyzing constant rate aquifer tests, step-drawdown tests, and slug injection or bail tests.

This is designated a Service-Learning Class.


Each student will be required to work with local High Schools (e.g. Troy High School), in a “hands on” demonstration of Applied Environmental Hydrogeology.   The purpose is to develop relationships with the students of local high schools and increase the student’s awareness of local groundwater issues. The student’s involvement will bring together CSUF students with future students and increase their interest within the field of geology and hydrogeology.  The students of CSUF will gain valuable experience in dealing with the public on sensitive issues surrounding water quality and data gathering techniques. Where the students of the local high school will gain knowledge on local groundwater issues along with increasing their interest within college and the natural sciences.


Percentage of course grade for learning through service experience:


20% of the students overall course grade will be determined by the activities that the student undertakes and the write-up of that activity.


Total number of hours of service to be required:


The total number of hours of service will be a minimum of 20 hours.  These hours will involve the preparation of the Applied Environmental Hydrogeology demonstration and the actual demonstration.  Several hours will also be needed to develop the curriculum for the field activity. 


Proposed course assignments and related activities, including critical reflection on experiential learning:


Each student will be required to participate in the Applied Environmental Hydrogeology demonstration.  They will be responsible for all field activities and the educational materials presented.  This will reinforce the educational value of the course, and allow the students to gain valuable experience in dealing with the public or sensitive issues surrounding environmental issues such as drinking water.  This will be invaluable to the students as they embark on careers that will deal with such issues on a daily basis.  The idea of bringing the field to the classroom is innovative in that it is teaching both CSUF students how to communicate to the public complex issues but also exposing them to the next generation of scientists.


Grading Policy:


Service Learning Field Assignment            20%


Reports/homework                                  60%


Final Examination                                    20%


The reports will be based on the topic for that section of the course and presentations will be done throughout the semester, due to the seminar style class.
