“…In contrast, the concentration of chlortetracycline in runoff water continued to increase during the two subsequent irrigation events. Similar to our results, in a study of ivermectin leaching under rainfall, ivermectin was detected in water only at the first rainfall event, and aging of the manure pat likely prevented further release of ivermectin (Fernandez et al, 2011). In another field rainfall study, a steady decline of chlortetracycline leaching after the first 15 min of rainfall was observed (Kim et al, 2010b).…”

“…Several approaches and various systems have been used to evaluate the transport of beef cattle pharmaceuticals and to mitigate their exposure to nontarget organisms (Fernandez et al, 2011; Kay et al, 2004; Kay et al, 2005a; Kay et al, 2005b; Kim et al, 2010b; Rabolle and Spliid, 2000). Batch sorption experiments have been used to evaluate the sorption of pharmaceuticals (oxytetracycline, sulphachloropyridazine, metronidazole, olaquindox, and tylosin) on soils and to calculate corresponding sorption coefficients, which aid in the mitigation of these pharmaceuticals.…”

“…Also, the heterogeneity of soil and the channeling of water through soil macrospores under field conditions have been shown to influence the potential for sorption and degradation (Kay et al, 2004; Kay et al, 2005b). A few studies on pharmaceutical leaching from soil systems have been completed under field or near‐field conditions and scale (Fernandez et al, 2011; Kim et al, 2010b). Fernandez et al (2011) examined Holstein cross cattle manure (1 kg) containing ivermectin applied to 5‐m 2 leaching trays.…”

Fernandez et al (2011) examined Holstein cross cattle manure (1 kg) containing ivermectin applied to 5‐m 2 leaching trays. Their results showed the highest leaching rate of ivermectin only in the first rainfall events, with concentrations in runoff water ranging from 5 to 188 ng L −1 .…”

“…For example, concentrations of tetracyclines detected in soils have been found as high as 170 μg kg −1 , and concentrations up to 1 μg L −1 have been found in surface waters (Sarmah et al, 2006). At the same time, there is little data on the transport and mitigation of common beef cattle pharmaceuticals in irrigated pasture systems, which provide critical forage to ranching enterprises in grazed watersheds throughout the western United States (Fernandez et al, 2011). In these extensively managed (relative to CAFOs) systems, cattle density (less than 1 cow per hectare per year) and consequently the load of manure per unit area is significantly lower than in CAFOs.…”

The use of veterinary pharmaceuticals in beef cattle has led to concerns associated with the development of antibiotic resistance in bacteria and endocrine disruption in aquatic organisms. Despite the potential negative consequences, data on the transport and mitigation of pharmaceuticals in grazed watersheds with irrigated pasture are scarce. The objective of this study was to assess the transport of common beef cattle pharmaceuticals (i.e., oxytetracycline, chlortetracycline, ivermectin) via surface runoff and leachate from manure amended to grass-vegetated soil boxes under irrigated pasture conditions. The transport of pharmaceuticals from animal manure in surface runoff and soil leachate was relatively low and appears to be limited by desorption and transport of pharmaceuticals entrained in the manure. In surface runoff, less than 4.2% of applied pharmaceuticals in manure (initial concentration: 0.2 mg kg−1 of manure) were detected after three weeks of irrigation. Concentrations of pharmaceuticals in surface runoff and leachate never exceeded 0.5 µg L−1. The major portion of pharmaceuticals (up to 99%) was retained in the manure or in the soil directly beneath the manure application site. Based on the minimal transport of oxytetracycline, chlortetracycline, and ivermectin, the risk of significant transport for these targeted beef cattle pharmaceuticals to surface water and groundwater from manure on irrigated pasture appears to be relatively low.

Many contaminants of agricultural origin are released into rural environments, particularly at the soil surface. Their fate has been extensively investigated in repacked soils, but only few studies have addressed their transport in structurally preserved natural soils. Much remains unknown about their fate and transfer within and between environmental compartments, while the susceptibility of these compartments to the contaminants adverse effects can vary considerably. The lack of studies regarding surface and subsurface transfer of contaminants through intact soil compared with studies on repacked soil led us to propose a device and protocol for sampling intact soil monoliths (60 × 30 × 22 cm3, length, width, depth [LWD]) without heavy machinery. This is achieved by a modular design with removable top and bottom lid and a protocol of cutting the soil and replacing the affected bottom soil with a drainage layer of glass beads. The device allows the application of artificial rainfall events with simultaneous highly resolved quantification of infiltration excess overland flow and drainage discharge. It is designed to facilitate the collection of samples for physical, biological, and chemical analyses that fulfill cleanliness standards for organic contaminant analysis at trace levels using only poorly reactive stainless steel and glass materials. Testing of the device was performed by measuring the transfer of the antiparasitic drug ivermectin (IVM) through and over a silt‐loam pasture soil. This test case illustrates how the device can be used to gain valuable information on the transfer of trace organic contaminants through topsoils.
