SC 203 – WATER SUPPLY OF ORANGE COUNTY. Class presentation available.

Water supplies in our portion of California were seriously challenged in 2014 after three years of state-wide drought. The Governor’s declaration calling for 20 percent conservation was followed by the State Water Board’s emergency regulation requiring mandatory water use restrictions.  Water utilities then imposed water use restrictions on their users. Southern California’s regional water provider, the Municipal Water District of Southern California (MWDOC), used its drought storage reserves to help the region through the drought, which required two-thirds of its storage. Southern California was well prepared for the drought, unlike many other areas in the state. As drought preparedness and water reserves varied among utilities, some suppliers tended toward public education rather than strict enforcement to achieve water conservation.

The first three classes will examine local and regional water conditions as they exist in early 2015, the outlook for both the near- and long-term, how Orange County fits into the situation, and what is in store for the entire Southwest. Local, state and regional experts will join us for a factual and speculative outlook at water – our essential lifeline. There will be time for questions and discussion in each class session. The fourth class will take place at the Orange County Water District’s state-of-the-art Groundwater Replenishment System in Fountain Valley. This will be a self-drive visit to the world’s largest recycled water treatment facility.

Friday, March 6: Orange County’s Underground Water Supply  Did you know that wells that pump groundwater from aquifers beneath northern and central Orange County supply 70% of the water needs of the OCWD service area?  Find out how the aquifers are replenished and protected from seawater intrusion and land subsidence.  Learn about local hydrogeology and water issues from the perspective of the Orange County Water District (OCWD).

Friday, March 13: Municipal Water District of Orange County (MWDOC) Did you know that half of urban Southern California’s water is imported from the Colorado River and Northern California, and Orange County (MWDOC service area) relies on imported water to meet 45% of its average needs?

SC 202 Hip and Knee Problems and Solutions

Dr. Robert Murphy and Linda Murphy shared with us their orthopedic experience on how to diagnose, treat and aid recovery of hip and knee problems. Dr. Murphy has performed more than 10,000 joint replacements. He will discuss indications, risks, benefits, treatments, rehab, and what to expect for a final outcome. He will also explain the science behind why cartilage degenerates, and what is on the horizon for treating this problem in the future. These new approaches include growing cartilage, genetically growing your own new joint, and stopping or reversing progression so that no surgery need be done. Dr. Murphy was joined in this discussion by his wife Linda Murphy, an orthopedic nurse and educator.

Presenters: Dr. Robert Murphy, MD, MPH, is an orthopedic surgeon who recently retired and moved to our community after 38 years of practice in spine and total joint replacement surgery at Eisenhower Medical Center in Rancho Mirage. He completed his orthopedic training at UCSD and a Master’s degree in Public Health from UCLA. He has a-career long interest in US healthcare policy. Dr. Murphy was the founding member and Chairman of the Board of Desert Orthopedic Center at Eisenhower for 30 years and served on the Eisenhower Hospital Board of Directors for 14 years. He and his wife Linda (a nurse educator) remain active in orthopedics through their consulting firm, the Murphy Consulting Group.

SC 201 – GEOLOGY OF JOSHUA TREE NATIONAL PARK. Class presentation available.

SC 201           Geology of joshua tree national park

An overview of the geology and physiographic setting of Joshua Tree National Park will be presented in this lecture.  We will discuss geologic and tectonic development of the park that led to the formation of spectacular granitic rock formations that are more than 100 million years old.  We will also discuss the surficial processes that created the prominent outcrops.  Time permitting, historical mining and other land uses will be covered.

Presenter:    Mark Bordelon is an adjunct geology professor at Irvine Valley College.  He has taught at IVC for 13 years, including field study courses in California and western states.  He was previously a consulting geologist for more than 20 years.

SS 309: The American Healthcare System Update. Class presentation available.

The Affordable Care Act (ACA) of 2010 (Obamacare) is the largest piece of health care legislation ever enacted in the United States. The bill, ten titles or parts, covers eight general themes with only one that accesses care for the uninsured. Today there is general confusion and very little factual understanding in the general population regarding what the ACA is intended to accomplish. This two-session course will cover:

  • Past attempts at health care reform and why they failed.
  • How “Obamacare” was able to get passed this time around.
  • The theories that the law is based on.
  • What is in the law.
  • How the law will likely be changed and improved in the future.
  • How the law will affect the way healthcare is delivered in the future.
  • How the changes will be paid for.

This course is an in-depth overview of healthcare in the United States that will help people better understand the rapidly changing U.S. healthcare system that will impact all of our lives for many years to come. It will update the very popular Fall 2013 class by Dr. Murphy. Presenter: Dr. Robert Murphy, M.D., M.P.H., is an orthopedic surgeon recently retired after 38 years of practice at Eisenhower Medical Center in Rancho Mirage.  Dr. Murphy completed his orthopedic training  at UCSD and has a Master’s degree in Public Health from UCLA.  He has a career-long interest in U.S. healthcare policy. He and his wife Linda (a nurse           educator) remain active in orthopedics through their consulting firm, Murphy     Consulting Group.
