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.

Title:  

Climate Fluctuations in Illinois, 1901-1980

 
 Volume/Number:    
 Issuing Agency:   
 Description:  Changes in climate directly affect four areas of major ctivity and concern in Illinois water, energy, agriculture, and transportation. This report presents selected Illinois records for 1901-1980 on a variety of atmospheric conditions that allow assessment of climate fluctuations, climate trends, variability around the trends, and impacts of these changes on the four areas of concern. Documented are changes in statewide and regional precipitation and temperature, plus selected point (station) data. Also presented are changes in other atmospheric conditions including relative humidity, sky cover and sunshine, visibility and related air quality smoke/haze/dust), severe local storms, and wind speed and direction. The historical records are carefully evaluated as to quality. Analyses of the data indicate changes in the more recent 20 years (1961-1980 compared with 1901-1960) to wetter and cooler conditions: more rain and snow and fewer droughts; decreases in temperatures especially in summer and winter, with fewer extremely warm days and many more extremely cold days; increases in cloudiness and decreases in sunshine and clear days especially in summer; and increases in wind speeds with more diverse wind directions. All trends are more marked in the extreme seasons of summer and winter than in the transition seasons of spring and fall, although somewhat warmer springs have produced a slightly longer growing season in the recent period. Mixed regional changes are noted in other atmospheric conditions, and no trend is apparent for relative humidity.

The General Report gives a summary of the chemical, biological and engineering work done and an account of the special investigations made during the year. Some interesting and valuable scientific investigations have been carried on by both the chemists and engineers. Advice relative to public water supplies has been given a large number of cities and plans for all new projects have been reviewed and reported upon. Extensive sanitary surveys of watersheds have been made which are proving of much value to cities facing the problem of sewage treatment. This work should be continued to cover all the watersheds of the state. During the year a co-operative arrangement has been perfected with the Rivers and Lakes Commission which increases the effectiveness of the Survey's work along the lines of stream cleaning. Thorough investigations have been made of several typhoid fever epidemics, suspected of being water borne. The most important of Health. During the Ohio River floods of April, the Survey was able to render valuable service in protecting water supplies and establishing sanitary conditions.

Chemical survey of the waters of Illinois: report for the years 1897-1902

 
 Volume/Number:  1903  
 Issuing Agency:   
 Description:  SIR: Herewith I submit a report of the work of the Chemical Survey of the Water Supplies of Illinois, covering the years 1897 to 1902, inclusive. As was stated in my preliminary report, published in 1897, portions of which are incorporated in the present report, the aims of the survey include the determination of the present sanitary condition of the water supplies drawn from the lakes, the streams, and the wells of the State; the determination of the normal condition of uncontaminated waters; the formulation of local standards of purity based upon the results of analyses of water derived from unpolluted sources; the provision of such means as shall afford to citizens of the State opportunity to obtain immediate information regarding the wholesomeness of the potable waters in which they are directly interested; and in general the prevention of the development and dissemination of disease from the use of impure water. The press of work in certain of these directions has been so great that comparatively little has been accomplished in others, and a mass of data concerning the normal condition of ground waters must be left for digestion and discussion at some future time. The present report may be broadly divided into three parts, namely: 1. A brief consideration of the sanitary condition of the ordinary ground waters and matters relating thereto. Accompanying this there is a paper upon 'The Geology of Illinois as Related to Water Supplies,' by Charles W. Rolfe, Professor of Geology in the University. 2. Results of the mineral analysis of some four hundred and sixty samples of water mainly from wells of considerable depth. 3. A report of the investigation of the surface waters of the State, relating chiefly to the Illinois River and some of its tributaries. Most of the routine work of these investigations has been conducted by Mr. C. V. Millar, M. S., and Mr. R. W. Stark, B. S., to whom special commendation is due for the continued interest, the skill and the unfailing zeal with which they have furthered the purposes of the Survey. At various times we have further been ably assisted by Mr. F. C. Koch, M. S.; Mr. E. P. Walters, B. S.; Mr. A. D. Emmett, B. S.; and Mr. A. L. Marsh. Respectfully submitted, ARTHUR W. PALMER, Sc .
