Cannon Air Force Base Groundwater Contamination:
Per- and Poly-Fluoroalkyl Substances Detected in Cannon Air Force Base Groundwater

CLOVIS, N.M. – The New Mexico Environment Department (NMED), the New Mexico Department of Health (NMDOH), and the New Mexico Department of Agriculture (NMDA) have been informed by Cannon Air Force Base that Per- and Poly-Fluoroalkyl Substances (PFAS), chemicals associated with fire-fighting foams - used by Cannon Air Force Base personnel - have been detected in groundwater on and off base. PFAS are emerging chemicals that may be associated with an increased risk of cancer and other health ailments. They are also known to be environmentally persistent, mobile in groundwater, and bioaccumulate in the food web. The U.S. Environmental Protection Agency has set a lifetime drinking water Human Health Advisory for two PFAS chemicals at 70 nanograms per liter (ng/L), or parts per trillion.

The United States Air Force (USAF) has advised that PFAS have been detected in a small number of the 19 off-base wells tested thus far. Some of these wells supply drinking water to local dairies. The Air Force has reported detections in off base wells with concentrations ranging from 25 to 1,600 ng/L. 

The Air Force has informed affected residents of the test results and is making bottled water available for drinking and cooking for wells that exceed the 70 ng/L Health Advisory.

PFAS have been detected in on-base monitoring wells at concentrations exceeding 26,000 ng/L.

NMED, NMDOH and NMDA are working collaboratively to ensure that the Air Force addresses this issue. Because this is an emerging issue across the nation with minimal available scientific data, the NMDA has requested that the U.S. Food and Drug Administration (FDA) immediately determine if any impacts on health exist, and if so, that the FDA establishes a regulatory threshold for PFAS in dairy products. NMDA requested that a decision be expedited.

NMED is overseeing the Air Force’s investigation of the PFAS contamination pursuant to the New Mexico Ground and Surface Water Protection Regulations, 20.6.2 NMAC. NMED is requiring further, extensive sampling of the affected area by the USAF. In a letter dated September 26, 2018, NMED required the Air Force to submit a comprehensive proposal to further delineate the groundwater plume; sample all water supply wells within a four-mile radius of the southeastern corner of the Air Force base; supply drinking water to affected well owners; and to resample the drinking water system on the Base.

Until further testing confirms an “all clear”, the use of bottled water for those residents and businesses with private domestic wells within a 4-mile radius of the Cannon AFB property boundary is recommended. Residents are encouraged to call the NMDOH Epidemiology and Response Division’s on-call line at (505) 827-0006 for consultation about the results of their well water test, or for information about how to get their well water tested.

Contaminación de aguas subterráneas de la Base de la Fuerza Aérea Cannon:
Detectadas sustancias per y poli-fluoroalquiladas en las aguas subterráneas de la Base de la Fuerza Aérea Cannon

CLOVIS, NM - El Departamento de Medio Ambiente de Nuevo México (NMED, por su sigla en inglés), el Departamento de Salud de Nuevo México (NMDOH, por su sigla en inglés) y el Departamento de Agricultura de Nuevo México (NMDA, por su sigla en inglés) han sido informados por la Base de la Fuerza Aérea Cannon que las sustancias per y poli-fluoroalquiladas (PFAS, por su sigla en inglés), productos químicos asociados con las espumas contra incendios, utilizados por el personal de la Base de la Fuerza Aérea de Cannon, han sido detectados en aguas subterráneas dentro y fuera de la base. Los PFAS son productos químicos emergentes que pueden estar asociados con un mayor riesgo de cáncer y otros padecimientos de salud. También se sabe que persisten en el ambiente, son móviles en el agua subterránea y son bioacumulables en la red alimenticia. La Agencia de Protección Ambiental de los Estados Unidos ha establecido un aviso de salud humana para el agua potable de por vida para dos productos químicos PFAS a 70 nanogramos por litro (ng/L), o partes por trillón.

La Fuerza Aérea de los Estados Unidos (USAF, por sus siglas en inglés) ha informado que han sido detectados PFAS en un pequeño número de los 19 pozos fuera de la base analizados hasta el momento. Algunos de estos pozos suministran agua potable a las lecherías locales. La Fuerza Aérea ha informado a los residentes afectados sobre los resultados de los análisis y está haciendo que haya agua embotellada disponible para beber y cocinar en pozos que exceden la recomendación de salud de 70 ng/L.

Se han detectado PFAS en pozos de monitoreo en la base a concentraciones superiores a 26000 ng/L.

NMED, NMDOH y NMDA trabajan en colaboración para garantizar que la Fuerza Aérea aborde este problema. Debido a que este es un problema emergente en todo el país con un mínimo de datos científicos disponibles, NMDA ha solicitado que la Administración de Drogas y Alimentos de los Estados Unidos (FDA, por su sigla en inglés) determine de inmediato si existe algún impacto en la salud y, de ser así, un umbral reglamentario para los PFAS en productos lácteos. NMDA solicitó que una decisión sea acelerada.

NMED está supervisando la investigación de la Fuerza Aérea sobre la contaminación por PFAS de conformidad con el Reglamento de Protección de Aguas Subterráneas y Superficiales de Nuevo México, 20.6.2 NMAC. NMED requiere un muestreo adicional y extenso del área afectada por parte de la Fuerza Aérea de los Estados Unidos (USAF). En una carta fechada el 26 de septiembre de 2018, NMED exigió que la Fuerza Aérea presentara una propuesta integral para delinear aún más la pluma de agua subterránea; un muestreo de todos los pozos de suministro de agua dentro de un radio de cuatro millas de la esquina sureste de la base de la Fuerza Aérea; suministro de agua potable a los propietarios de los pozos afectados; y un remuestreo del sistema de agua potable en la Base.

Hasta que las pruebas posteriores confirmen un "todo resuelto", se recomienda el uso de agua embotellada para aquellos residentes y negocios con pozos domésticos privados dentro de un radio de 4 millas del límite de la propiedad de Cannon AFB. Se recomienda a los residentes que llamen a la línea de llamadas de la División de Epidemiología y Respuesta de NMDOH al (505) 827-0006 para consultar sobre los resultados del análisis de agua de su pozo o para obtener información sobre cómo realizar un análisis de agua de su pozo.
