In this province, information regarding groundwater distribution and quality is very scarce, and the monitoring of water resources quality is not carried out periodically. It is well known that several pesticide families, such us organophosphates, carbamates and neonicotinoids, are applied in this region to maintain crop quality and production. Pesticide application by ground-based spraying equipment, the climatic conditions and the physical and chemical properties of these compounds, facilitate that a substantial fraction of the active ingredient may reach air, soil and water sources. The objective of this study was to evaluate the pesticide presence in groundwater, in order to provide information about the water quality for human consumption. Seventeen organophosphate and four carbamate residues were monitored from 2014 to 2015 by gas chromatography with a nitrogen-phosphorus detector, in groundwater samples collected from depth wells, located in rural areas corresponding to Senillosa, Plottier, Vista Alegre and Centenario cities, in Neuquén province. These cities are intensive agricultural areas, which supply the North Patagonia region with fresh fruits and vegetables, and where groundwater is utilized for human consumption. In this study, organophosphate and carbamate concentrations were below 0.020 and 0.030 µg/L, respectively, and lower than the accepted limits established by the Guidelines for Canadian drinking water quality (2017) and the Guidelines for drinking water quality (2011) of the World Health Organization for these pesticides.]]></p></abstract>

En esta provincia, la información sobre la distribución y calidad de las aguas subterráneas es muy escasa y el monitoreo de la calidad de los recursos hídricos no se realiza periódicamente. Es bien sabido que en esta región se aplican varias familias de pesticidas, tales como organofosforados, carbamatos y neonicotinoides, para mantener la calidad y la producción de los cultivos. La aplicación de pesticidas por equipos de pulverización en tierra, las condiciones climáticas y las propiedades físicas y químicas de estos compuestos, facilitan que una fracción sustancial del ingrediente activo pueda llegar a las fuentes de aire, suelo y agua. El objetivo de este estudio fue evaluar la presencia de plaguicidas en aguas subterráneas, con el fin de proporcionar información sobre la calidad del agua para consumo humano. Diecisiete organofosforados y cuatro carbamatos fueron monitoreados entre 2014 y 2015 por cromatografía de gases con detector de nitrógeno-fósforo, en muestras de aguas subterráneas recogidas de pozos profundos ubicados en zonas rurales correspondientes a las ciudades de Senillosa, Plottier, Vista Alegre y Centenario, en la provincia de Neuquén. Estas ciudades son zonas agrícolas intensivas, que abastecen a la región norte de Patagonia con frutas y verduras frescas, y donde el agua subterránea se utiliza para consumo humano. En este estudio, la concentración de organofosforados y carbamatos fue menor a 0.020 y 0.030 &#956;g/L, respectivamente, e inferior a los límites aceptables establecidos por la guías para la calidad del agua potable de Canadá (2017) y de la Organización Mundial de la Salud (2011) para estos plaguicidas.]]></p></abstract>
