Environmental Change in Arizona Reservoirs
This aspect of my research program focuses on how mercury and other metals are delivered to
lakes and reservoirs, and how reservoirs differ from lakes in their capacity to create sediment
records of water quality, primary productivity, and hydrology. My initial projects were
concerned with establishing chronologies for sediment cores from about a dozen northern
Arizona reservoirs and analyzing those sediments for anthropogenic metals. My students and I
are now refining our techniques to reconstruct past storm and wildfire events by analyzing our
archive of sediment cores for a variety of physical and chemical parameters. We are working
toward the goal of tracking the sequestration and release of mercury stored in terrestrial
ecosystems. With a recent project on Watson Lake, Arizona, we are also working on
reconstruction of primary productivity and nutrient-cycling histories in reservoirs.

Natural Biomonitors of Atmospheric Deposition of Metals
My research on delivery of metals to reservoirs led to interest on the occurrence and variability
of atmospheric metals on the landscape. Naturally occurring biomonitors provide a proxy for
the deposition of a variety of anthropogenic compounds. Initial research on this topic was
initiated through the efforts of a NSF Research Experiences for Undergraduates (REU) student I
mentored in 2006. We sampled the epiphytic lichen Xanthoparmeila, which occurs widely
across Arizona. Our analysis of these samples for mercury resulted in the publication of a peerreviewed journal article and funding to collect baseline data associated with the commissioning
of the Drake Cement Plant in the Verde Valley, Arizona. I was also invited to join a research
group in Italy to sample lichens to detect effects of a smelter in central Italy.

Ballston Lake
Research in applied limnology and paleolimnology has been tightly linked with undergraduate
education through projects on Ballston Lake. Typical of lakes with watersheds that have
undergone human development, Ballston Lake supports moderate to high primary productivity.
The north basin of this 4 km-long elongated lake is also fairly typical of glacially-influenced lakes
in the US northeast, in that it has an average water depth of about 7 meters and contains
sediments about 6 meters thick, overlying glacial clays and gravel. The southern end of Ballston
Lake, however, features a 32-meter deep sub-basin, which remains permanently chemically
stratified, or meromictic. Anoxic and highly reducing conditions have allowed sediments to
accumulate in a well-preserved, laminated sediment package 16-meters thick.
Through the Environmental Studies program at Union College, the departments of Civil
Engineering, Geology, Biology, and Chemistry have taken advantage of Ballston Lake as a focus
for a variety of class exercises and undergraduate thesis projects. Projects have varied widely,
from studies of nutrient transformations across adjacent wetlands, to studies of the unusual
chemical transformations with depth, to detailed analysis of sediment cores recovered from the
meromictic basin. The mission for undergraduate research experiences for students has also
driven faculty research. My current research program includes geochemical analysis of the
Ballston Lake cores and hydrodynamic modeling of the lake to determine energies necessary
de-stratify the meromictic basin.
Projects Funded:
Limnological Equipment for the Ballston Lake Initiative. Co-Principal Investigator. National
Science Foundation, Division of Undergraduate Education. June 1998 to May 2000. $158,945.

Schoharie County Groundwater Study
Groundwater resources protection in the Town of Wright, Schoharie County, New York. The
principal aquifer for the town is a selectively transmissive karst unit, replete with sinkholes,
springs, and a network of dry and flooded caves. The objective of this study is to identify
potential point-sources of recharge to the aquifer and determine flowpaths of major
insurgences and springs. Techniques for analysis include hydrologic mass balances and tracer
studies using dyes and introduced rare-earth metals.

participation in the New York State Federation of Lake Associations watershed management
program.
Project manager for a water quality and biology assessment project on Deer Point Lake, Bay

Coastal Restoration
Project manager for the Caernarvon and Davis Pond freshwater diversion projects. Mississippi
River water is diverted into the Breton Sound and Barataria Bay estuaries to mimic some of the
ecological functions that were served by periodic overbank flooding of the river prior to the
construction of levees along the river. These functions included sediment, freshwater, and
nutrient delivery to marshes that would otherwise not have these sources to stimulate primary
productivity. These projects affect a combined area of over 1.3 million acres of marsh and
inland waters. Nearly a third of all marine organisms commercially harvested in the lower 48
United States spend some part of their life cycle in one of these estuaries. Duties included
chairing the Caernarvon Technical Advisory Committee, implementing the water control plans
for Caernarvon and Davis Pond, and managing contracts with the US Army Corps of Engineers,
local governments, and support contractors. The combined construction budgets for these
projects exceeded $175 million and annual budgets for operations and maintenance, exceeded
$500,000. Additional duties included hosting tours of the projects to interested parties
including congressional, White House, and international media visitors.
Supervisor of the Thibodaux Field Office in the Field Engineering Section of the Louisiana
Department of Natural Resources. Supervised two professional engineers. Activities included
construction, operation, maintenance, repair, and replacement of coastal restoration projects.
Restoration strategies included renourishing and replanting barrier islands, modifying the
hydrology of impaired coastal marshes, and controlling erosion at interfaces of marsh and open
water.
Hydrology
Designed and implemented a study to quantify relative contributions of direct surface runoff
and shallow groundwater in a shallow central-Florida aquifer using environmental stable
isotope tracers. Derived and applied mass-balance models at the watershed and sub-catchment
levels to trace sources of river flow using isotopic end member (surface runoff and
groundwater) water masses.
Project manager for the Lake Jackson facility improvement project, Tallahassee, Florida.
Developed design drawings and bid documents for renovation of a stormwater treatment
facility to remove particulate solids from stormwater prior to treatment in a constructed
wetland.
Project engineer for a two-year study to quantify hydraulic and water quality effects (thermal,
nutrient, and sediment loading) of extended-detention ponds on small, urban watersheds in
Montgomery County, Maryland. Responsibilities included developing and implementing field
and data-handling protocols and data analysis.
Environmental Science and Engineering

and assess the state of drinking water quality in Nizhnevartovsk, Russia, a city of approximately
250,000 located in the petroleum-development region of western Siberia.
Project manager for the design and construction of remediation systems for leaking
underground petroleum storage tank facilities. Responsibilities included remediation process
and construction design; compliance with environmental regulations and budgets; and liaison
with client representatives, permit granting authorities, and subcontractors.
Project manager for Phase I and Phase II environmental and geotechnical audits. Objective was
to determine whether subsurface environmental contamination was present, or had migrated,
on site. Activities included researching local and state government environmental data and
legal records, installing and sampling soil borings and monitoring wells, conducting geotechnical
analyses to determine the suitability of the site to shallow-foundation development, and
preparing summary reports.
Project manager for the design and implementation of a fuel-spill cleanup on Florida's Turnpike.
Contamination consisted of approximately 2,000 gallons of jet fuel released from an overturned
tank truck. Remediation consisted of excavating and incinerating approximately 2,300 tons of
contaminated soil. Site constraints included excavation within structural portions of the
roadway and maintaining safe traffic flow during work operations.
Project engineer for several projects involving control of aquatic plants. One project involved
maintaining navigational access to marinas in the Potomac River estuary. Another project
involved assessing the feasibility of harvesting hydrilla as a nutrient control strategy in Lake
Okeechobee, Florida.
