Irrigation pollution story told Environmental Prelection Agency (EPA) officials' in Washington have a better Idea of the problems of western irrigators as a result of a recent presentation given on agricultural pollution by Tom Pitts of Loveland. Pills, manager of the Toups Corporation, consulllng engineers, Loveland division, gave the same presentation to the directors of the Northern Colorado Water Conservancy District (NCWCD) along with his report that the information had been well received in Washington. "I believe we are establishing an understanding of the variety of factors that muddle the plans to control stream pollution," Pitts told the NCWCD directors. "Most of the agency people have had little previous experience with irrigation and were under the impression that pollution control would be staple. "Now they are beginning to realize the complexity of the problem. We are hoping they will give us whatever time is necessary for thorough research and planning of controls that will effect the major goals of the EPA without causing undue burden on agriculture. Little information is available on the actual costs and'benefits of agricultural pollution control measures." Pitts' report to the EPA was based on work conducted as a major element of the Larimer- Weld "206" program sponsored by the Council of Governments (COG). The prime water user in the two counties is agriculture with its 500,000 irrigated acres and many feedlots. Since agriculture is the chief element in the regional economy, there is concern over the economic impact of pollution control regulations. Pitts said lack of data on items such as the nature and significance of pollutant" discharges is the greatest impediment to the study being conducted by his company. There . is not sufficient information on the magnitude of discharges, stream hydrology or the impact on stream quality and flow. "For these reasons," Pitts said, "Our program includes stream measuring, soil sampling, discharge measuring and sampling, and collection of daily records of diversion for 87 locations in the two county region." Phase One of the analysis was performed during the summer of 1976. This was a study to define water quality impacts of irrigated agriculture. Phase Two this summer will be an analysis of best management practices (BMP): This BMP analysis will provide data on the interrelationship of factors c o n t r o l l i n g p o l l u t a n t discharges; data needed to assess the effectiveness of these practices in reducing discharges; and an estimate of the cost. A farm sampling program, recognizing the highly localized nature of the pollution problem, will study irrigation methods, drainage practices, soil chemistry and texture,.applied water quality, topography, irrigation efficiency and subsoil conditions. "These variable factors control pollutant discharges," Pills said. "These are dissolved solids (a salinity) including nitrates and sediment. "Best management practices are not free, but there may be offsetting benefits in addition to pollution reduction. These benefits could include water conservation, energy savings and increased crop yield." Pitts said some form of demonstration projects will be needed to determine effectiveness under field conditions, the actual operating and maintenance costs, and the impact on the farm economy.
