793:		Title:	Pilot study: agricultural chemicals in rural, private wells in Illinois
		Volume/Number:	1992
		Issuing Agency:
		Description:	In the Illinois Groundwater Protection Act of 1987 (PA 85-863), the state legislature mandated that the Illinois Department of Energy and Natural Resources (DENR) conduct an "ongoing program of basic and applied research relating to groundwater," including an evaluation of pesticide impacts upon groundwater. "Such evaluation shall include the general location and extent of any contamination of groundwaters resulting from pesticide use. . . . Priority shall begven to those areas of the State where pesticides are utilized most intensively." In response to this mandate, the Illinois State Water Survey (ISWS) and the Illinois State Geological Survey (ISGS), divisions of DENR, developed a plan to assess the occurrence of agricultural chemicals in rural, private wells on a statewide basis (McKenna et al. 1989). In response to the concerns regarding the proposed statewide survey, a separate pilot study was designed, based on the recommended statewide survey, to produce tangible, documented results of well-water sampling and to demonstrate the validity of the survey design.The legislative mandate addressed the pesticide impacts on groundwater. The proposed statewide plan and the pilot study will focus on groundwater drawn from rural, private wells. This approach will maximize data acquisition on the potential for exposure of the rural residents of Illinois to agricultural chemicals (pesticides and nitrogen fertilizers) through drinking water; it will also minimize sample collection costs. Inferences drawn from this project are valid for groundwater drawn from rural, private wells and not from other sources.

794:		Title:	Contribution to the characterization of Illinois reference/background conditions for setting nitrogen criteria for surface waters in Illinois : final report to Illinois Council on Food and Agricultural Research (C-FAR)
		Volume/Number:	2000
		Issuing Agency:
		Description:	The United States Environmental Protection Agency (USEPA) National Regional Nutrient Criteria Development Program is developing regional-specific criteria for total nitrogen concentrations in surface waters. These criteria will provide the foundation for states to set total nitrogen standards to remedy impairments caused by nutrient overenrichment and to protect designated uses. Reference conditions representing minimally impacted surface waters will be developed for each ecoregion. All nutrient criteria must be based on sound scientific rationale. The first element of a nutrient criterion identified by USEPA is "... historical data and other information to provide an overall perspective on the status of the resource." The second element includes " ... a collective reference condition describing the current status." A further element requires "... attention to downstream consequences." The USEPA recognizes that nutrient concentrations in surface waters are primarily affected by the rate of weathering and erosion from watershed soils. Human activity can affect on the natural load of nutrient inputs to surface waters through, for example, vegetation disturbance of the vegetation, and addition of nutrient-containing material, such as fertilizer. At the heart of the overenrichment problem are the rates of production and decomposition of organic materials, of which nitrogen is a component. This report provides a contribution to the setting of reference/background conditions for Illinois through the evaluation of the current status of water resources against historical conditions, and some attention to downstream consequences. A particular focus of downstream consequences is hypoxia in the Gulf of Mexico, allegedly caused by the flux of excess nitrogen from the Upper Mississippi, Ohio, and Missouri River Basins. The concept of biogeochemical cycling provides an appropriate and necessary framework for understanding landscape influences on water quality throughout the Illinois River Basin. Changes in the Illinois River Valley and its system of tributary streams and lakes are well recognized, but this is the first attempt to assess in some detail how such changes have affected the aquatic carbon, oxygen, and nitrogen cycles; especially the impact of such watershed changes on the nature and quantity of aquatic nitrogen, as well as on the nitrogen cycle within the terrestrial reservoir. This is seen in the accompanying time line of the estimated nitrogen richness of the Illinois landscape. Scientists studying soils and crops from the mid-19th through mid-20th centuries documented that human activities have greatly altered the natural nitrogen cycle. Cultivation of virgin land typically depleted nitrogen and carbon stored in these reservoirs by about 50 percent in the first 60-70 years of cultivation. Some of this nitrogen was transferred to surface waters and ground waters. The depletion of nitrogen from soils in the Mississippi River Basin was so great that crop yields declined throughout the 19th and early 20th centuries. By mid-20th century, the extensive use of nitrogen fertilizer, improved plant varieties, and agronomic practices increased crop yields. Nitrogen fertilizer also began to replenish some of the large amounts of nitrogen previously removed from the soil. In the 1970s, profound changes occurred in the perception of the natural nitrogen cycle and human modification of that cycle. The nitrogen cycle, and human impacts on it came to be defined in terms of atmospheric nitrogen fixation and the return of nitrogen gases by nitrification/denitrification. The 99 percent of the nitrogen cycle which was otherwise cycled within and between the large soil, sediment, and plant reservoirs were no longer acknowledged. From this new definition of the nitrogen cycle, it was concluded that human activities, especially fossil-fuel combustion and fertilizer use, had doubled the nitrogen cycle and many lands, including much of Illinois, had become nitrogen saturated. Increasing concentrations of nitrate-nitrogen in surface waters were given as evidence of nitrogen saturation and leakage. This new limited edition of the nitrogen cycle became cast in concrete and is referred to in this report as "the new, standing nitrogen-cycle paradigm." This report uses the earlier, scientifically more complete and defensible definition of the nitrogen cycle, which includes recognition of the magnitude and importance of soil-plant reservoirs and exchanges. It uses extensive scientific documentation of major changes in ecosystems and soil nitrogen that have occurred over centuries, to place into perspective the present status of nitrogen resources -- as required by USEPA. This report examines the impact on nitrogen concentrations in surface waters in Illinois during occupation of the land by Native Americans, bison, and many other animals and birds. Theoretical impacts are complemented by written accounts of early settlers and scientific observations made under similar conditions. It is concluded that the landscape and surface waters were more nitrogen saturated at this time than today. These pre-European-settlement conditions were selected as the reference/background conditions. Just prior to and during the period of early European settlement, the populations of Native Americans and bison were eliminated and the landscape became less nitrogen saturated. Nevertheless, even in the 1820s, the Illinois River was hypertrophic, i.e. nutrient overenriched. As late as the 1850s, the amount of eroded soil transported by the Mississippi River was more than twice that transported in recent decades. Since soil erosion is reported to be the major sort of N delivery from agricultural lands, the N load in the Mississippi River was declining. The average annual concentration of total nitrogen in the Lower Illinois River in 1894-1899 was 3.68 mg N/l, and additional large amounts of nitrogen not measured were stored in plankton and luxuriant aquatic vegetation and transported downstream in copious amounts of organic debris. Allowing for the unmeasured flux of nitrogen as plankton and for low flow, the adjusted average annual concentration of total nitrogen in the Lower Illinois River in 1894-1899 is estimated to have been about 5.5 mg N/l. This report also examines the impact of European settlement and agriculture on the nitrogen cycle and water quality. Scientific data show that the average concentration of total nitrogen in the Lower Illinois River increased to about 10 mg N/l by mid-20th century and subsequently decreased to 4.8 mg N/l in the 1990s. The annual concentration of nitrate in the Lower Illinois River peaked at about 6.2 mg N/l in 1967-1971 and subsequently decreased to about 3.8 mg N/l in 1993-1998. These improvements in water quality are associated with an increasing amount of dissolved oxygen in the river. The reductions in the concentrations of all forms of nitrogen are attributable to both point- and nonpoint-source pollution control. The main conclusions of this report are that, in establishing scientifically sound reference/background conditions, it is necessary to quantify in a common unit all forms of nitrogen (in solution, as solids, and as gases; and organic and inorganic forms) and all sources, reservoirs, transformations, and fluxes of nitrogen in a common unit; and to understand interactions between nitrogen and other biogeochemical cycles of, for example, water, oxygen, carbon, and phosphorous. Criteria for setting nitrogen standards must recognize the great complexity of the nitrogen cycle and its interdependence with other variables, cycles, and anthropogenic influences.

795:		Title:	Phase I: diagnostic-feasibility study of Homer Lake, Champaign, Illinois.
		Volume/Number:	2000
		Issuing Agency:
		Description:	The Champaign County Forest Preserve District (CCFPD) applied for and received a grant to conduct a diagnostic-feasibility study on Homer Lake commencing in April 1997. Homer Lake is an 83-acre public lake within the Salt Fork River Forest Preserve in Champaign County, Illinois. The lake is located in the Second Principle Meridian, Township 19N, Range 14W, Section 31; it is 3 miles northwest of the town of Homer. Homer Lake has a maximum depth of 19 feet, a mean depth of 7.4 feet, a shoreline length of .3 miles, and an average retention time of 0.097 years. The Homer Lake watershed, including the lake surface area, is 9,280 acres. The two inflow tributaries are Conkey Branch and the west branch (unnamed). The diagnostic study was designed to delineate the existing lake conditions, to examine the cases of degradation, if any, and to identify and quantity the sources of plant nutrients and any other pollutants flowing into the lake. On the basis of the findings of the diagnostic study, water quality goals were established for the lake. Alternative management techniques were then evaluated in relation to the established goals.

796:		Title:	Dewatering well assessment for the highway drainage system at five sites in the east St. Louis area, Illinois (FY95-Phase12)
		Volume/Number:	2000
		Issuing Agency:
		Description:	In the East St. Louis vicinity, the Illinois Department of Transportation, Division of Highways (IDOT) owns 55 high-capacity wells that are used to maintain the elevation of the ground-water table below the highway surface in areas where the highway is depressed below the original land surface. The dewatering systems are located at five sites in the alluvial valley of the Mississippi River in an area known as the American Bottoms. The alluvial deposits at the dewatering sites are about 90 to 115 feet thick and consist of fine sand, silt, and clay in the upper 10 to 30 feet, underlain by medium to coarse sand about 70 to 100 feet thick. The condition and efficiency of a number of the dewatering wells became suspect in 1982 on the basis of data collected and reviewed by IDOT staff. Since 1983, IDOT and the Illinois State Water Survey (ISWS) have conducted a cooperative investigation to more adequately assess the operation and condition of the wells, to attempt to understand the probable causes of well deterioration, and to evaluate rehabilitation procedures used on the wells. Work conducted during FY 95 (Phase 12) included monitoring the rehabilitation of four wells, step-testing the rehabilitated wells and checking the discharge from two wells for sand pumpage, checking the quality of the water discharged during the step tests, and monitoring the ground-water levels at the dewatering system sites. Posttreatment step tests were used to help document the rehabilitation of four dewatering wells, Interstate-70 (I-70) Wells 3A, 5, 11A, and 15, during FY 95 (Phase 12). Chemical treatments used to restore the capacity of these four wells were moderately successful. The improvement in specific capacity per well averaged about 103 percent based on data from pre- and posttreatment step tests. The specific capacity of I-70 Well 15 was restored to about 109 percent of the average observed specific capacity of wells in good condition at the I-70 site and the other three wells were restored to about 72 to 87 percent of the average observed specific capacity for wells in good condition. The sand pumpage investigation conducted during the posttreatment step tests on I-70 Wells 3A and 11A showed little or insignificant amounts of sand in the portable settling tank after the step tests. The tank was required to divert the discharged water into the stormwater drainage system during the other two step tests, precluding a check for sand pumpage.

797:		Title:	Operation of rain gauge and ground-water monitoring networks for the Imperial Valley Water Authority, year seven : September 1998-August 1999
		Volume/Number:	2000
		Issuing Agency:
		Description:	The Illinois State Water Survey (ISWS), under contract to the Imperial Valley Water Authority (IVWA), has operated a network of rain gauges in Mason and Tazewell Counties since August 1992. The ISWS also established a network of ground-water observation wells in the Mason-Tazewell area in 1994. These networks are located in the most heavily irrigated region of the state. The region's major source of water for irrigation, municipal, and domestic water supplies is ground water pumped from thick sand and gravel deposits associated with the confluence of two major ancient river valleys, the Mississippi and the Mahomet-Teays. Relatively recent extreme weather events (e.g., the drought of 1988 and the great flood of 1993) resulted in large fluctuations in ground-water levels in the Imperial Valley area. The purpose of the rain gauge network and the ground-water observation well network is to collect long-term data to determine the rate of ground-water drawdown in dry periods and during the growing season, and the rate at which the aquifer recharges. This report presents data accumulated from the rain gauge and observation well networks since their inception through August and November 1999, respectively. Precipitation is recorded for each storm that traverses the Imperial Valley, and ground-water levels at the 13 observation wells are measured the first of each month. The database from these networks consists of seven years of precipitation data and five years of ground-water observations. At the beginning of the ground-water observations in late 1994, the water levels were at their highest in the five years of observation. These high ground-water levels were the result of the very wet 1992-1995 period when annual precipitation was above the 30-year normals at both Havana and Mason City. From September 1995-August 1997 precipitation in the region was below the 30-year normal. The 1997-1998 observation year had rainfall above the 30-year normal. Ground-water levels in the observation wells mirrored these rainfall patterns, showing a general downward trend during the dry years and a recovery in the wet 1997-1998 year. Seasonal increases in the ground-water levels were observed at most wells during the late spring and early summer, followed by decreases in August-November ground-water levels. Analysis indicates that the ground-water levels are affected by both the precipitation in the Imperial Valley area and the Illinois River stages. The observation wells closest to the Illinois River show an increase in water levels whenever the river stage is high. Generally, the water levels in the wells correlate best with precipitation and Illinois River stages one to two months before the water levels are measured, i.e., the June ground-water levels are most highly correlated with the Illinois River stage or precipitation that occurs in either April or May. The analyses conducted indicate the need for continued operation of both networks due to inconsistencies associated with ground-water levels, precipitation, and the Illinois River stage. For instance, the Mason-Tazwell observation well number 2 (MTOW-2) is located near the center of Mason County well away from the Illinois River, but it has an equal correlation with the Illinois River stage and the precipitation in the area. Additional analysis needs to be undertaken to explain this unusual finding.

798:		Title:	Watershed monitoring for the Lake Decatur watershed, 1998-1999
		Volume/Number:	2000
		Issuing Agency:
		Description:	Lake Decatur is the water supply reservoir for the City of Decatur. The reservoir was created in 1922 by constructing a dam to impound the flow of the Sangamon River with an original water volume of 20,000 acre-feet and an area of 4.4 square miles. The dam was later modified in 1956 to increase the maximum capacity of the lake to 28,000 acre-feet. Water withdrawal from the lake has been increasing over the years, averaging 37 million gallons per day (mgd) in 1994. The drainage area of the Sangamon River upstream of Decatur is 925 square miles. The watershed includes portions of seven counties in east-central Illinois. The predominant land use in the watershed is row crop agriculture comprising nearly 90 percent of the land area. The major urban areas within the watershed are Decatur, Monticello, and Gibson City. Lake Decatur has high concentrations of total dissolved solids and nitrates, and nitrate concentrations have been exceeding drinking water standards in recent years. This has created a serious situation for the drinking water supply of the City of Decatur. The Illinois Environmental Protection Agency (IEPA) has issued nine nitrate warnings to the city from 1979 to 1996 for noncompliance with Nitrate-N concentrations in Lake Decatur have exceeded the Illinois Environmental Protection Agency (IEPA) drinking water standards for nitrate when concentrations exceeded of 10 milligrams per liter (mg/l) for the period between 1979 and 1998, except from 1993 to 1995. On June 10, 1992, a Letter of Commitment (LOC) was signed between the IEPA and the City of Decatur. The LOC requires the city to take several steps to reduce nitrate levels in Lake Decatur to acceptable concentrations within nine years of signing the LOC. Nitrate-N cannot be removed from finished drinking water through regular water purification processes. One of the steps required the city to conduct an initial two-year monitoring study of the Lake Decatur watershed to better understand nitrate yields in the watershed. In 1993, the Illinois State Water Survey received a grant from the City of Decatur, conducted a two-year monitoring study, and developed land use management strategies that could assist the city comply with the IEPA drinking water standards (Demissie et al., 1996). This technical report presents the annual data for all six years of monitoring (May 1993-April 1999) and monthly data for the sixth year of monitoring (May 1998-April 1999).

799:		Title:	Bank erosion survey of the Illinois River : volume 2 : appendices
		Volume/Number:	2000
		Issuing Agency:
		Description:	This report summarizes the research and surveying that were conducted in 1995 to determine the amount and severity of bank erosion that existed on the entire length of the Illinois River. The study reach extended from Grafton, River Mile (RM) 0 to Joliet, RM 286. A multi-disciplinary team of scientists traveled the entire length of the river, mapped bank conditions and erosion sites, and selected 29 reaches for detailed data collection and two sites as observation sites. Bank erosion types were developed by studying and analyzing the erosion features. The team also used fluvial and bank failure processes to guide detailed data collection at the 29 sites. Color-coded bank feature maps were developed for the entire 286 miles of the river.
