Water Quality Modeling in NY/NJ Harbor: A Historical Perspective on the Present

For an article providing a historical perspective on Water Quality Modeling in the New York/New Jersey Harbor, click here. By Robin L. Miller and James J. Fitzpatrick.


Pat Kehrberger named Assoc. of Environmental Authorities Member of the Year

Pat Kehrberger, an Associate at HydroQual, Inc., has worked in the field of water quality modeling since 1970. Her experience involves water quality evaluations using steady-state and time-variable mathematical models. Specific projects have included wasteload allocations, stormwater coliform distribution, sludge solids deposition in an estuary, dye data simulation in an estuarine bay to determine net inter-tidal circulation, ocean disposal and mixing zone analyses.

Her experience also includes design and execution of field sampling programs for use in modeling analyses to determine waste assimilation capacity of low flow streams. Several projects have also involved evaluation of post-development eutrophication impacts on drinking water supply reservoirs.

Pat has served on AEA's Permit committee for many years and has been helpful in contributing to the association's rule proposal comments in particular in the area of water quality standards. Pat's real world experience in solving permit issues for her clients brings a practical and very professional approach to the committee's work. She has been a speaker at technical conferences and is a great team player.

It is with great pleasure and sincere appreciation that AEA has selected Pat Kehrberger as this year's Outstanding Associate Member.


Di Toro Named to National Academy of Engineering

Dominic M. Di Toro, Ph.D., a founding Principal of HydroQual, Inc., and the current Edward C. Davis Professor of Civil and Environmental Engineering at the University of Delaware, has been elected to the National Academy of Engineering.  He was recognized for “leadership in the development and application of mathematical models for establishing water-quality criteria and making management decisions.”

In being elected to the National Academy, Dr. Di Toro joins fewer than 2200 engineers nationwide. “This is probably the highest honor that a consulting engineer can achieve in the field of engineering,” said William Leo, President of HydroQual, Inc.

Areas in which Dr. Di Toro’s work has had the greatest impact are water quality and sediment flux modeling, and sediment and water quality criteria development. Early in his career, he developed one of the first dynamic water quality models that was used to predict the consequences of nutrient discharges to the Great Lakes. The results were used in the joint US-Canada agreements to limit discharges to Lake Erie.

In the late 1980s, the EPA embarked on the development of Sediment Quality Criteria, and Dr. Di Toro was the technical leader of the effort through the 1990s. The Equilibrium Partitioning model and the SEM/AVS method that were developed are now part of common practice. More recently, he and his colleagues have developed criteria models for mixtures of polynuclear hydrocarbons (PAHs) that have recently been published by EPA.

Dr. Di Toro served as the technical director of the HydroQual Team that is developing and applying the Biotic Ligand Model (BLM) to various metals. Beginning with copper, the team examined the factors that control the bioavailability and toxicity of copper to aquatic organisms. This work resulted in the Biotic Ligand Model which successfully linked metal chemistry with effects to explain and predict metal toxicity. The HydroQual Team, now lead by Paul Paquin and Robert Santore, continues to work on copper, silver, aluminum, zinc, and cobalt. The BLM for copper has been incorporated into the USEPA 2004 draft water quality criteria document for copper and similar plans are in place for silver and zinc.

Dr. Di Toro joined the University of Delaware in January 2003 after serving on the faculty at Manhattan College for more than 30 years. He has published over 100 technical papers, as well as a book, Sediment Flux Modeling (John Wiley & Sons). One reviewer called the book “the definitive text on this subject and deserving of a place in any respectable environmental library” and by another as “masterfully done.”


Robin L. Miller appointed to USGS Advisory Committee

Robin L. Miller was appointed the Water Environment Federation (WEF) representative to the Sedimentation Issues Subcommittee of the Advisory Committee on Water Implementation of USGS in February 2005. This is the first time that non-governmental representatives have served on this committee.
