“…Contaminants of emerging concern (CEC) are chemicals and other substances that are largely unregulated in the United States, but which, because of advancements in analytical chemistry, are now reliably and routinely detected in surface waters across the nation [1][2][3][4][5]. Trace-level concentrations of CECs can alter aquatic ecosystems at multiple trophic levels, from biofilms to fish [6][7][8][9][10][11][12][13]. CECs with designed-bioactivity (e.g., pharmaceuticals, pesticides, hormones) are particular concerns for the structure and function of aquatic ecosystems [12,[14][15][16][17], owing to ubiquitous environmental sources [18][19][20][21][22][23] and the diversity of evolutionarily-conserved, molecular endpoints [24][25][26][27][28].…”

Pharmaceuticals and personal care products (PPCPs), wastewater indicators (WWIs), and pesticides (herein, Contaminants of Emerging Concern [CECs]) have been documented in surface waters throughout the world and have associated risks to aquatic life. While much research has focused on temperate and urbanized watersheds, less is known about CEC presence in semi-arid landscapes, where water availability is limited and populations are low. CEC presence in water and sediment is reported for 21 sites in eight U.S. national parks in the northern Colorado Plateau region. From 2012 to 2016, at least one PPCP and/or WWI was detected at most sites on over half of sampling visits, indicating that CECs are not uncommon even in isolated areas. CEC detections were generally fewer and at lower concentrations than in urbanized or agricultural watersheds. Consistent with studies from other U.S. regions, the most frequently detected CECs in this study include DEET, caffeine, organophosphorus flame retardants, and bisphenol A in water and fecal indicators and polycyclic aromatic hydrocarbons in sediment. Maximum concentrations in this study were generally below available water quality benchmarks, sediment quality guidelines, and risk assessment thresholds associated with vertebrates. Additional work is needed to assess the potential activity of hormones, which had high reporting limits in our study, and potential bioactivity of environmental concentrations for invertebrates, microbial communities, and algae. Potential sources of CEC contamination include upstream wastewater effluent discharges and National Park Service invasive-plant-control herbicide applications. CEC occurrence patterns and similarities between continuous and isolated flow locations suggest that direct contamination from individual visitors may also occur. While our data indicate there is little aquatic health risk associated with CECs at our sites, our results demonstrate the ubiquity of CECs on the landscape and a continued need for public outreach concerning resource-use ethics and the potential effects of upstream development.

“…Eighteen other TOCs also were detected at concentrations that were less than laboratory reporting limits but were included in the data tables because most are pharmaceuticals (including antibiotics) and currently have unknown ecotoxicological significance (Daughton and Ternes, 1999;Battaglin and Kolok, 2014). Although treated wastewater effluent has been included in the water rights acquisition program, permits for discharge of treated effluent to both the Truckee and Carson Rivers had been granted prior to enactment of the acquisition program.…”

“…However, although water availability is the primary limiting factor for wetland management in Lahontan Valley (Engilis and Reid, 1996), potentially toxic contaminants associated with mining, milling, and irrigation drainage have been shown to adversely affect the ecological health of the area Higgins and Miesner, 2002). Due to their persistence, trace organic compounds (TOCs) associated with treated domestic and industrial wastewater effluent, urban runoff, and leachate from livestock and dairy operations also may affect the ecological health of SNWR (Battaglin and Kolok, 2014) and potentially accumulate in the internally drained watershed.…”

“…That is, because GBHs are considered safe, governmental agencies do not regularly test agricultural land or food products for residues. Despite lack of systematic testing, studies have discovered glyphosate's remarkable pervasiveness in soil, the human microbiome, food, and water (Battaglin and Kolok 2014;Bai and Ogbourne 2016;Cuhra, Bøhn, and Cuhra 2016;Myers et al 2016;Van Bruggen et al 2018). In the 2000s, the U.S. Geological Survey found low levels of glyphosate or its principal metabolite (AMPA) in 58 percent of nearly 4,000 soil and water samples from thirty-eight states.…”

The Glyphosate Assemblage: Herbicides, Uneven Development, and Chemical Geographies of Ubiquity

The ubiquity of chemicals demands new ways of thinking about human-nature assemblages. This article develops a dialogue between agrarian political economy, critical commodity chains research, and chemical geographies through a case study of the world's most widely used agrochemical: glyphosate, commonly known as Monsanto's Roundup. In the 1980s, glyphosate triumphed as a benign biocide that promised both safety and effectiveness. This construct made possible a capitalist agricultural assemblage characterized by chemical pervasiveness, first as a chemical replacement for mechanical tillage and since the 1990s as the chemical input for genetically modified seed packages. The ubiquity that characterizes the glyphosate assemblage is also a geography of uneven development comprising shifting firm networks, policies, and trade. Central to this assemblage since 2000, yet largely ignored, is the outsized expansion of second-and third-tier generic pesticide producers, especially in China, for whom glyphosate is part of a network entry and upgrading development strategy. Today, the glyphosate assemblage faces unprecedented challenges from weed resistance and health controversies. Whether and how the herbicide assemblage restabilizes will be determined by the complex environmental and developmental challenges of chemical agriculture and pervasive chemicals broadly, which highlights the need for a transdisciplinary dialogue that cuts across these domains.
