Low Flow Sampling and Hydraulic Conductivity Analysis
Tuesday, June 5, 2018
University of Connecticut, Storrs, CT
Gary Robbins, Ph.D., University of Connecticut
Continuing Education Credits:
This is a new course and is the first time being offered. The CT State Board of Examiners of Environmental Professionals (LEP Board) has approved this course for 4.0 hours of continuing education credits (CTLEP-449). This course has also been approved for 4.0 technical credits (Course #1629) by the MA LSP board.
Time and Location:
Registration will begin at 12:30 PM, the program runs from 1 PM - 5 PM. The course will be held at University of Connecticut, Storrs, CT, Beach Hall - room 317. Further directions and parking information will be sent to registrants.
A laptop with Microsoft Excel (tm) installed is required for this course. Following registration, you will be provided to links to download other analysis software to be used in the course.
The collection of accurate water quality samples is essential in evaluating contaminated groundwater conditions. However there is a host of factors that can bias sampling data. The objective of this course is to review sampling bias and procedures for minimizing such bias through low flow sampling or means consistent with low flow sampling.
This course will begin with a review of factors that can introduce sampling bias and why low flow sampling has been adopted. Next, we will review the latest EPA guidance and review the significance of each indicator parameter and how indicator parameters are not only a guide to when to sample but also important in assessing contamination conditions. We will also cover how to use the drawdown and pumping rate achieved during low flow sampling as a means to determine the hydraulic conductivity of the formation being sampled.
The outdoor field demonstration will entail a low flow sampling event at a typical monitoring well. Different equipment will be also demonstrated. Attendees will record and analyze data Following field testing, the instructors and attendees will reconvene in the classroom to discuss the results of the field test and answer any questions.

Dr. Gary Robbins is a Professor of Geology in the Department of Natural Resources and the Environment at the University of Connecticut in Storrs, CT. Professor Robbins is well known for his research work aimed at improving site investigations at contamination sites. Often called "the consultants consultant", he has offered training courses across the country for the private sector and the EPA. He is the author of Expedited Site Assessment: The CD, the recipient of a Contribution to Practice Award by the Massachusetts LSPA, the recipient of the University's Chancellor Information Technology Award, and is the 2016-2017 UCONN Teaching Innovation Awardee. Prior to coming to UConn he worked for Woodward-Clyde Consultants and before that the Nuclear Regulatory Commission. He has been called upon as a private consultant, expert witness and arbitrator for the private sector and government entities. He is a CPG with AIPG, a Registered Geologist and Certified Engineering Geologist in California, and a member of EPOC.
