The investigation revealed the use of aqueous film-forming foam, known as \u2018AFFF.\u2019 AFFF, which contains PFAS, is the most effective product for extinguishing aircraft fires and was used at Wallops in fire training operations and emergency response beginning in the late 1970s. As a result of this use, there were known or suspected releases of AFFF to the environment. Today, Wallops only uses AFFF for aircraft emergencies.<\/p>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>NASA IS TAKING ACTION<\/strong><\/h2>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Protecting the Area\u2019s Water Supply<\/strong><\/h3>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>Town of Chincoteague<\/em><\/strong><\/h4>\n\n\n\n<p>Following the 2016 investigation, NASA initiated a groundwater testing program.

Water runs through two treatment tanks prior to release to Town of Chincoteague’s drinking water system. The second tank is a safeguard to remove any residual PFAS that may be detected in  water that exits from the first tank.                               <\/div><div class=\"hds-credits\">NASA\/Patrick Black<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The groundwater treatment system, funded, designed, and installed by NASA, can treat 410 gallons per minute of groundwater from wells that supply water to the Town\u2019s drinking water system to prevent exposure to PFAS in drinking water. Under a permit from the Virginia Department of Health, the system has been fully operational since April 2021 and has successfully removed PFAS, meeting EPA\u2019s drinking water standards well before they were finalized.<\/p>\n\n\n\n<p>The Town\u2019s wells are sampled quarterly, and drinking water is sampled monthly using EPA approved methods. All results are shared with the Town and with federal and state health and environmental agencies. Results show the drinking water meets EPA drinking water standards which were finalized in April 2024.<\/p>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How Groundwater Treatment Works<\/strong><\/h3>\n\n\n\n<p>The treatment system uses a proven technology for removing PFAS known as granular activated carbon (GAC). Four large tanks each contain 10,000 pounds of granular activated carbon (GAC). As groundwater passes through the tanks, GAC adsorbs the PFAS. Over time, the GAC becomes saturated and needs to be replaced. The tanks are set up so when the GAC is being replaced, another tank takes the lead, and the other tanks provide backup. This layout ensures PFAS removal is continuous.   <\/p>\n\n\n<div id=\"\" class=\"hds-image-carousel grid-container grid-container-block padding-top-8 padding-bottom-8 hds-module hds-module-full wp-block-nasa-blocks-image-carousel\">\t\t<div class=\"hds-carousel-wrapper\">\n\t\t\t<div class=\"image-carousel-slider margin-0\" id=\"image-carousel-slider\">\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"display-block width-full\">\n\t\t\t\t\t\t\t<figure class=\"margin-0\">\n\t\t\t\t\t\t\t\t<div class=\"hds-cover-wrapper hds-image-carousel-slide margin-bottom-2\">\n\t\t\t\t\t\t\t\t<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?w=1024\" class=\"attachment-large size-large\" alt=\"\" style=\"transform: scale(1.2); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg 1600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=300,225 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=768,576 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=1024,768 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=1536,1152 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=400,300 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=600,450 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=900,675 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/toc-gac.jpeg?resize=1200,900 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Inside NASA\u2019s groundwater treatment system began operation in April 2021 at NASA’s Wallops Flight Facility in Virginia.<\/div><\/figcaption><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"display-block width-full\">\n\t\t\t\t\t\t\t<figure class=\"margin-0\">\n\t\t\t\t\t\t\t\t<div class=\"hds-cover-wrapper hds-image-carousel-slide margin-bottom-2\">\n\t\t\t\t\t\t\t\t<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?w=1024\" class=\"attachment-large size-large\" alt=\"A pair of hands wearing blue gloves cupped together holding granules of carbon.\" style=\"transform: scale(1.02); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg 5184w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=300,200 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=768,512 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=1024,683 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=1536,1024 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=2048,1365 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=400,267 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=600,400 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=900,600 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=1200,800 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/05\/water-tx-series-150.jpg?resize=2000,1333 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The treatment system uses granular-activated carbon to adsorb PFAS as groundwater passes through the tanks.
