Iowa’s Ambient Water Monitoring Program At A Glance
BERNIE HOYER (Iowa DNR-Geological Survey Bureau, Iowa City)
Since 1999, support for Iowa's ambient monitoring program has increased. Find out what
monitoring occurs for Iowa’s streams, lakes, beaches and groundwater,
and how citizen monitors participate through IOWATER.
Long-Term Trends in Nitrate Concentrations in Iowa’s Rivers
BOB LIBRA (Iowa DNR-Geological Survey Bureau, Iowa City)
Nitrate concentrations in Iowa rivers have increased from the 1940-1950s to the
1980-1990s. Statistical comparison of nitrate data from the Iowa, Cedar
and Des Moines rivers illustrating this trend will be presented.
Stream Monitoring: Historical Trends and New Directions
MARY SKOPEC (Iowa DNR-Geological Survey Bureau, Iowa City)
Sixteen Iowa streams have been monitored monthly since 1986. What trends do the
data show and what are typical concentrations for the common parameters?
In 1999, stream monitoring expanded from 16 to 60 sites, and sites were
added both upstream and downstream of 10 of the larger interior cities
located on streams.
Quality of Iowa’s Lakes: Monitoring Results from Year One
JOHN DOWNING and JOY RAMSTACK (Iowa State University, Dept. of Animal Ecology,
Ames)
130 Iowa lakes are being monitored as part of a five-year program. Monitoring
began in 2000, and all lakes are monitored three times each year. Find out
which lakes are being monitored, what parameters are being monitored, and
what has been learned about the water quality of Iowa’s lakes. Hear how
the water quality of Iowa lakes compares to other places in the world and
what additions are planned for lake monitoring during 2001.
Use
of Fish and Benthic Macroinvertebrates to Evaluate Water Quality
TOM WILTON (Iowa DNR-Water Quality Bureau, Des Moines)
Fish and benthic macroinvertebrate populations were sampled at 57 stream sites
in 2000. The diversity and abundance of these aquatic organisms are useful indicators of stream
biological health and water quality. This presentation will describe how biological assessments are
done, results from 2000, and plans for 2001.
Access to Iowa’s Water Databases and STORET
MARY SKOPEC and JOOST KORPEL (Iowa DNR-Geological Survey Bureau, Iowa City)
Data from Iowa’s Ambient Water Monitoring Program are managed using the U.S.
Environmental Protection Agency’s modernized STORET (STOrage and
RETrieval Database). This presentation will discuss plans for public
retrieval of water quality data, not only from STORET, but also IOWATER
and other data sources. Innovative new tools for accessing and viewing
data will be described, including Web-based interfaces.
IOWATER Makes a Splash
RICH LEOPOLD (Iowa DNR-Geological Survey Bureau, Des Moines)
LYNETTE SEIGLEY (Iowa DNR-Geological Survey Bureau, Iowa City)
More than 500 citizen monitors participated in 18 IOWATER workshops in 2000.
Monitors have registered over 370 monitoring sites and submitted over
1,000 data sets to the IOWATER on-line database. Learn how IOWATER will
expand in 2001 to include Level 2 training and monitoring of soils, lakes
and benthic macroinvertebrate indexing.
Bacterial Monitoring of Iowa’s Beaches
LIZ SHINALL (Iowa DNR-Geological Survey Bureau, Iowa City)
Thirty-one
state-owned beaches were monitored weekly from May through September 2000
for three bacterial indicators: fecal coliform, enterococci, and E.
coli. Four of the thirty-one beaches were also monitored twice daily.
Results from the weekly and daily sampling will be presented, as will
plans for this year.
Pharmaceuticals, Pesticide
Degradates, and Other
Emerging Contaminants in water: New analytical tools play Key Roles in Water Research
DOUG SCHNOEBELEN (U.S. Geological Survey, Iowa City)
New analytical tools allow water to be analyzed for a new range of parameters,
including prescription and non-prescription drugs, human and veterinary
antibiotics, hormones, and sterols. Find out which of these parameters
have been detected in a national study, and which of these will be
monitored in Iowa. Only in recent years have pesticide degradates
(breakdown products of the parent pesticide) been monitored. Results from
the monitoring of alachlor, acetochlor, and metolachlor degradates in
Iowa’s surface and groundwater will be presented.
Future Plans for Expansion of Iowa’s Ambient Water Monitoring
Program
BERNIE HOYER (Iowa DNR-Geological Survey Bureau, Iowa City) The
current proposal before the Iowa Legislature is to increase funding for
the Ambient Water Monitoring Program by one million dollars. New funding
will allow for: sediment monitoring, a private water well assessment to
evaluate drinking water available to the rural population,
monitoring of Class C drinking water sources, expansion of IOWATER,
expansion of a groundwater monitoring well network and a
probability-based assessment of Iowa streams using biological organisms.
