Synopsis: 

Well disinfection, Greg Reyenke, Pacific Water Quality Association
Introduction groundwater/surface bacteria, nuisance bacteria -vs- pathogens, principles/practice of well disinfection, how to minimize contamination/transmission, and the implications of downstream contamination.

Nebraska grout Study, unexpected results, Dan Meyer, NGWA past president    
Review results from the study, some basic do's and dont's of various grouts, discuss some tools that should be used during grouting operations but rarely are.

Nitrates, are they really an issue? Larry Newcomb, Jayhawk Consultants
The nitrate standard is being revised by the EPA. This speakers data suggests nitrates should return to a secondary standard.

E-logs in fractured rock, Bill Pedler, Realtime Aquifer Services
Learn how these can be used to design a well around water quality parameters (like uranium, nitrates, TDS, etc.), and determine where to best set the pump based on water quality and quantity parameters, in both a new and existing wells.

Tim Guishard has over 32 years of experience in the groundwater industry. He holds certifications from AWWA in several backflow related topics, has held a CDPH T-1 Water Treatment Plant Operator certification, and currently holds a SWRCB certification as a D-1 Distribution System Operator. He is the CGA Education Committee Chairman, and sits on the Scholarship, Legislative, and Convention Committees.

Larry Newcomb Never to be retired Sanitarian (aka Registered Environmental Health Specialist) with a commitment to solving problems with land use projects involving onsite wastewater disposal and potable water supplies.  Grew up in a rural area of Kansas (hand dug shallow well, no plumbing, wood stove and no TV until 1957.  Thought we lived in paradise despite the state bird being a mosquito and being  flooded by the Republican River. Proud to have served our country more than six years on an ammunition ship and three submarines with a final rank of MM1(SS)  Started college 1966, graduated from SDSU in 1970 with a double major in Chemistry and Microbiology while working as a refrigeration and air conditioning mechanic.  This was followed by private sector positions in applied research with reverse osmosis,  Microbiology quality control, wastewater chemistry and a public-sector position as an environmental specialist with the San Diego County Departmentof Environmental Health (including a 14-year stint as a supervisor).  Founded Jayhawk Consultants, LLC in 2004. (Previously had an environmental consultingbusiness from 1977 to 1986).

Bill Pedler has over thirty years experience in researching, developing and applying methods for aquifer characterization and the evaluation of subsurface flow and water quality. As the original developer of the Hydrophysical Logging technology in the late 80s in association with the Lawrence Berkeley National Laboratory, Pedler has dramatically improved the understanding of the science as well as the integration of both new and traditional techniques in the field, with a specific early focus on application of methods in fractured bedrock hydrology.  Pedler has been integrally involved in testing 1000s of wells on 100’s of projects ranging from nuclear waste isolation studies to water resource development, groundwater management planning, environmental investigations and water management associated with mining.  In addition, Pedler has taught classes and other training seminars on borehole geophysics and hydrophysics for government and private industry for the last 20 years.  As one of the premier technologists of groundwater flow and water quality today, Pedler manages RAS’s California office to serve the growing need to accurately characterize, measure and monitor groundwater hydrogeology throughout the state.  He also oversees RAS’s operations throughout the US, Canada and Mexico.



Greg Reyenke has over two decades of ongoing experience in the Water Treatment Industry. His expertise spans the full gamut of residential, commercial and industrial applications including wastewater treatment, groundwater remediation, bacterial control, and advanced corrosion control strategies.
Greg is currently the Secretary/Treasurer of the Pacific Water Quality Association (PWQA) and Chairs their Education Committee.
Greg writes prolifically and travels worldwide, teaching about improving human life through better water quality. You can follow him on his blog at www.gregknowswater.com
