Appearance of liquid manure in water at various dilutions. Final report (July 2003) [359KB pdf].  Fleming, R., VandeWeghe, J., MacAlpine, M., Ridgetown College, U. of Guelph -  Based on the observations using one sample of liquid swine manure, the following appear to be true: · Manure in water at a ratio of 1:5000 was barely visible when the initial water was clear. Concentrations of 1:500 should be visible in most cases. It is therefore possible that water could contain unacceptable levels of manure-sourced bacteria even though it appears to be clear.

In a global context of increasing water shortage induced by rises in population and average living standard, decision-makers must seriously consider the pressure of trade in water as significant environmental stressors on the Great Lakes.

Environmental Fate of Nitrate in the Assiniboine Delta Aquifer (Manitoba) (Dec. 2000)(2498 KB pdf). by David L. Burton and M. Cathryn Ryan, LRCS Land Resource Consulting Services For Manitoba Horticulture Productivity Enhancement Centre Inc.  The risk of nitrate contamination of the Assiniboine Delta Aquifer as a consequence of agricultural activities is high, due to the characteristics of the aquifer and its geological setting, and to the suitability of the land for agricultural development and use. Expansion of intensive crop production, irrigation, and livestock production would further increase this risk. A clear assessment of the risk requires a field- and groundwater-based study to elucidate the potential for denitrification, including the nature and long-term supply of electron donors and their associated groundwater impacts.

Impacts of Winter Spreading of Manure on Water Quality: A Literature Review [100 KB pdf] (2000). Ron Fleming, and Heather Fraser, Ridgetown College, Univ. of Guelph, Ridgetown, Ontario N0P 2C0. One of the goals of this literature review was to outline the various risk factors associated with winter-spreading of manure. However, the single greatest impact is "weather". Since this is a factor that is out of the control of the farmer and cannot be accurately predicted, the risk of runoff from winter-spread manure will be low some years and high in other years.

Nitrate and Phosphorous Levels in Selected Surface Water Sites in Southern Ontario: 1964-1994 [597 KB PDF]  Ron Fleming and Heather Fraser. Ridgetown College, Univ. of Guelph.  Is surface water in Ontario improving or is the quality dropping over time? Which land use typically creates the greatest contribution of phosphorus and nitrate to surface water? These are the questions that this study attempted to answer. Water quality data from selected surface water monitoring sites were examined. The sites were part of a network established by the Ontario Ministry of the Environment. The data that was considered covered the period from 1964 to 1994. This was not intended to be an exhaustive study, but rather it was used to give a good snapshot of water quality trends. Objectives of the study were to use existing water quality data from the Ministry of the Environment to:  1) Show the current and past state of surface water nitrate-N and total phosphorous levels;  2) Recognize trends in nitrate and phosphorous levels over time; and  3)Identify relationship among nutrient levels, watershed uses and management practices.

Animal Wastes as a Source of Drinking Water Contamination. UCD EXTOXNET FAQ Team; The EXtension TOXicology NETwork - Animal production facilities can be a source of drinking water contamination if wastes are not properly managed. Microorganisms, nitrogen, and phosphorus are the prime contaminants from manure. There are various types of microorganisms present in fecal waste that cause severe illness and disease if ingested. Excessive amounts of nitrogen, in the nitrate form, which is converted to the nitrite form in the body, will prevent oxygen from binding to hemoglobin in the blood. Infants are especially sensitive to excess nitrite and can suffer methemoglobinemia, or "Blue Baby Syndrome".

An Analysis of Local Benefits And Costs of Michigan Hog Operations Experiencing Environmental Conflicts (08/28/97)- Mark Abeles-Allison and Larry J. Connor, Agricultural Economics Report #536, Dept. of Agric. Econ., Michigan State U., East Lansing, MI 48824  - report examines local benefits and costs associated with hog operations for which odor complaints had been received in Michigan. A regression analysis approach was  used to determine the implicit prices of hog odors on property values. Property values were regressed against household and neighborhood characteristics of residential properties surrounding these hog farms. The benefit/cost ratios for a 500 and 5,000 head hog operations in a township with a $20 million State Equalized Valuation (SEV) are 5.64 and 3.86 respectively. The study indicates that the ratio of benefits to costs increase (improve) as SEV declines. This means that damages are dependent upon property value. As the amount of property value in the area declines, damages decline.

Environmental Policies and Agricultural Land Values: Evidence from the Dutch Nutrient Quota System [145 KB pdf]. Tomislav Vukina and Ada Wossink, Dept of Agric.& Resource Econ., N. Carolina State U., Nelson Hall, Raleigh, NC 27695-8109 - paper analyzes the impact of the phosphate based animal production rights on agricultural land values in the Netherlands. We claim that the existence of mandatory production control program with regional restriction on trading causes a disproportional increase in land prices in the surplus region where the quota is binding relative to the deficit region where the quota is not binding and that the increase in the cost of environmental compliance should generate an eroding effect on the existing gap in land prices. The parameters of an inverse land demand model estimated with panel data support both hypotheses.
