Page 1 of 3

Facility Profile Physical Profile Release Profile Land Use and Exposure

Profile Ecological Profile

Installation Description/History: Years of operation: 1942 to the present. Size: Approximately 3,789 acres. Location: Eastern New Mexico, approximately 7 miles southwest of the City of Clovis, in Curry County, New Mexico.

Layout: The installation is comprised of two perpendicular active runways in the central and southwestern portions; maintenance, support, and operational facilities west of the central runway/flightline; supplemental hangars and apron areas in the south‐central region; a wastewater treatment plant to the east; and, a golf course and residential and service facilities in the northwestern portion (HGL, 2015).

History: Cannon AFB dates to 1929 when Portair Field was established as a civilian passenger terminal. The Army Air Corps took control of the civilian airfield in 1942 and it became known as the Clovis Army Air Base. The installation was renamed Clovis Army Air Field in early 1945, where flying, bombing, and gunnery classes continued until the installation was deactivated in May 1947. The installation was reassigned to the TAC and formally reactivated as Clovis AFB in 1951, and subsequently renamed Cannon AFB in 1957 (Versar, 2013).

Current Mission: Home to the 27th SOW where it conducts infiltration/exfiltration, combat support, tilt‐rotor operations, helicopter aerial refueling, close air support, unmanned aerial vehicle operations, non‐standard aviation, and other special missions. It directs the deployment, employment, training, and planning for squadrons that operate the AC‐130W, MC‐130J, CV‐22B, C‐146A, U‐28A, MQ‐1, MQ‐9, and provides operational support to flying operations (Versar, 2013).

Topography:

The installation is situated in the Southern High Plains Physiographic Province near the center of the Llano Estacado subprovince. This area is a nearly flat plain sloping gently (10 to 15 feet per mile) to the east and southeast. In the vicinity of Cannon AFB, elevations range from 4,250 to 4,350 feet above mean sea level (AECOM, 2011).

Vegetation: Vegetation at Cannon AFB is typical of semiarid, short grass prairies (Plains‐Mesa grassland) and is limited by water availability (CH2MHill, 1983).

Much of the Llano Estacado (80‐90%) has been tilled for agriculture, with farmers producing cotton, corn, and wheat under dryland agriculture or irrigated with water pumped from the Ogallala Aquifer (USEPA, 2006).

Surface Water: Permanent surface water streams are non‐existent in the Cannon AFB vicinity. Running Water Draw, located approximately 10 miles north of the installation, is the nearest drainage feature and is dry for much of the year.

Historically, surface runoff at Cannon AFB has drained into four natural, ephemeral, playas. Two of the northern playas were converted into plastic‐lined golf course ponds. The southern playa, known as South Playa Lake, occupies approximately 9 acres south of the intersection of the main jet runways and is approximately 15 feet deep. Since 1943, stormwater runoff from the flightline has collected in this playa where it either evaporates or percolates into the soil. The northern playa, known as North Playa Lake, was bermed on the north, west, and south sides with topsoil and concrete debris. It covers approximately 13 acres and received treated effluent from the former sewage lagoons (AECOM, 2011).

Soils: Soils at Cannon AFB are predominantly fine sandy loams of the Amarillo series, which consists of very deep, well drained, moderately permeable soils derived from loamy eolian sediments from the Blackwater Draw Formation of the Pleistocene (United States Department of Agriculture [USDA], 2017).

Geology: The subsurface geology of the Southern High Plains aquifer at Cannon AFB includes the Chinle, Ogallala, and Blackwater Draw Formations.

The Chinle Formation of Triassic Age forms the bottom of the unconfined Southern High Plains Aquifer in this area, and consists primarily of clay with some intermixed sand and silt, and ranges in thickness from 0 to 400 feet in eastern New Mexico.

The Ogallala Formation of Tertiary Age is the main water‐yielding unit of the Southern High Plains Aquifer and lies unconformably atop the upper unit of the eastward‐dipping Chinle Formation. The Ogallala Formation consists of eolian sand and silt and fluvial and lacustrine sand, silt, clay, and gravel, and ranges in thickness from 30 to 600 ft in eastern New Mexico and west Texas.

The Blackwater Draw Formation of Quaternary Age generally overlies the Ogallala Formation at Cannon AFB. The Blackwater Draw Formation is

Contaminants of Potential Concern: PFAS are the contaminants of potential concern for this investigation. Fuel related compounds and chlorinated solvents are historical site contaminants.

Media of Potential Concern: Soil, sediment, surface water, and groundwater. Confirmed AFFF Releases: Former FTA No. 2: Possible AFFF use from 1970 to 1974 in unlined FTA with an unknown volume of AFFF used for firefighting training. PFOS and PFOA were detected in both surface and subsurface soil at concentrations below the calculated RSL. PFBS was not detected.

Former FTA No. 3: Possible AFFF use from 1970 to 1974 in an unlined FTA with an unknown volume of AFFF used for firefighting training. PFOS was detected above the calculated RSL in surface soil but was not detected in subsurface soil. PFOA was detected below the calculated RSL in the surface soil but not detected in subsurface soil. PFBS was not detected.

Former FTA No.4: Possible AFFF use from 1974 to 1995 with an unknown volume of AFFF used for firefighting training. PFOS was detected above the calculated RSL in surface soil but was not detected in subsurface soil. PFOA was detected at concentrations below the calculated RSL in surface and surface soil. PFBS was detected in subsurface soil at concentrations below the calculated RSL.

Hangar 119 and 133: Accidental releases of AFFF inside the hangars likely discharged to grassy areas outside the hangars. PFOS was detected above the calculated RSL in surface soil samples and below the calculated RSL in subsurface samples (28 to30 feet bgs). PFOA and PFBS were detected below the calculated RSL in surface and subsurface soil samples.

Former Sewage Lagoons: Operated between 1966 and 1998; during operation, lagoons received any AFFF that entered the sanitary sewer system. Evidence of AFFF releases in hangars during this time period, which may have entered the sanitary sewer system and been routed to the former sewage lagoons. Only subsurface soil sampling was conducted as part of SI activities as surface material was fill material. PFOS was detected above the calculated RSL in subsurface soil. PFOA and PFBS were detected below the calculated RSL in subsurface soil.

North Playa Lake Outfall: Any wastewater collected at the WWTP containing AFFF would be passed on to North Playa Lake. Several releases of AFFF from hangars entered the sanitary sewer system and were routed to the WWTP. PFOS was detected in sediment samples at concentrations below the calculated RSL. PFOA and PFBS were not detected in sediment. PFOS and PFOS+PFOA were detected/calculated in surface water at concentrations exceeding the USEPA HA value (0.07 µg/L). PFOA was detected in surface water at concentrations below the USEPA HA value. PFBS was detected in surface water at concentrations below the USEPA Tap Water RSL.

South Playa Lake Outfall: Any stormwater or wastewater containing AFFF that enters storm drains near the flightline is routed to South Playa Lake. Several releases of AFFF from hangars entered nearby storm drains and

Current Land Use: Occupied by Cannon AFB.

Future Land Use: Land use is not expected to change in the future.

Potential Receptors: Potential receptors associated with current and future land use include USAF personnel and residents, grounds maintenance workers, utility workers, construction workers.

Recreational users of Whispering Winds Golf Course.

Potential Ecological Receptors: Inland and aquatic plant species, reptiles, birds, soil invertebrates, and mammals that inhabit or migrate through the installation.

Threatened and Endangered Species: Threatened species that were identified in Curry County and may exist at Cannon AFB include the following: Lesser prairie‐chicken (Tympanuchus pallidicinctus) – under review.

AFFF Use: AFFF containing PFAS was used for firefighting training activities, testing of firefighting equipment, extinguishing petroleum fires, and in fire suppression systems at several installation buildings.

Fourteen potential AFFF release areas were recommended for SI at Cannon AFB: Former FTA No. 2; Former FTA No. 3; Former FTA No. 4; Hangars 119 and 133; Former Sewage Lagoons; North Playa Lake Outfall; South Playa Lake Outfall; Whispering Winds Golf Course Outfall. Hangar 109; Active FTA; Landfill #4; Perimeter Road Fuel Spill Flightline Crash Areas; and, Basewide Groundwater

composed primarily of eolian sand deposits, and ranges in thickness from 0 to 80 feet in eastern New Mexico.

A caliche layer is typically present in the unsaturated zone of the Blackwater or Ogallala Formations in New Mexico.

Hydrogeology: The lower portion of the Ogallala Formation is the primary regional aquifer for both potable and irrigation water.

The Ogallala Aquifer is part of the Southern High Plains Aquifer that extends across parts of southeast New Mexico and northwest Texas, which in turn is part of the larger High Plains Aquifer that extends continuously from Wyoming and South Dakota into New Mexico and Texas.

Cannon AFB is underlain by the portion of the Ogallala Aquifer designated the Curry County Underground Water Basin. The Ogallala Aquifer is a water table, or unconfined, aquifer with the underlying Chinle redbeds serving as the basal confining layer in eastern New Mexico.

At Cannon AFB, the depth to groundwater is approximately 300 feet bgs. The saturated thickness in 1990 ranged from 93 to 143 feet, but continues to decrease. Groundwater flow is generally from northwest to southeast (FPM, 2014).

Depth to water measurements collected in November and December 2017 as part of the SI ranged from 287.78 feet below top of casing (btoc) in monitoring well MW‐X located in the southwest portion of the installation to 351.80 feet btoc in monitoring well MW‐H located on the south side of the former sewage lagoon. The calculated groundwater elevations ranged from 3981.45 feet above mean sea level (amsl) in MW‐X to 3929.38 feet amsl at MW‐H.

Meteorology: Average annual rainfall is 17.9 inches/year in Clovis, New Mexico. Average number of days with measurable rainfall is 54 days. Average high temperature of 92°F occurs in July, while an average low of 23.4°F occurs in January.

were routed to the lake. PFOS and PFOA were detected in both surface and subsurface soil at concentrations below the calculated RSL. PFBS was not detected in surface or subsurface soil.

Whispering Winds Golf Course Outfall: The golf course began receiving effluent from the WWTP plant in approximately 2002. Currently, the golf course stores effluent in a storage tank on the eastern portion of the course. Effluent is regularly used for golf course irrigation and filling the two golf course ponds. A release of AFFF into any of the hangar floor trenches or fire station stalls would be routed through the WWTP. As such, effluent from the WWTP used at the golf course may contain AFFF. PFOS was detected in sediment samples at concentrations below the calculated RSL. PFOA and PFBS were not detected in sediment. PFOS and PFOS+PFOA were detected/calculated in surface water at concentrations below the USEPA HA value (0.07 µg/L). PFOA and PFBS were not detected in surface water.

Hangar 109: A recent release of AFFF inside the hangar/mechanical rooms resulted in AFFF being released outside the hangar and draining o grassy areas outside the hangar. PFOS was detected above the calculated RSL in surface soil but was not detected in subsurface soil samples. PFOA and PFBS were detected below the calculated RSL in the surface soil sample and was not detected in the subsurface soil sample.

Landfill No. 4: Landfill is located immediately north of the North Playa Lake. Cover was irrigated using water from North Playa Lake where wastewater from WWTP (potentially including AFFF) was discharged. Groundwater was sampled downgradient of the landfill (monitoring well LF04‐MW‐Na). No PFOS, PFOA, or PFBS were detected.

Active FTA: Lined evaporation pond located south of the FTA where AFFF/water mix is collected and left to evaporate has been repaired in the past. Any damage to liner would result in AFFF being released to environment. In addition, an extreme flood event in May 2015 likely resulted in the evaporation pond overflowing, allowing residual AFFF to infiltrate into surrounding soil. PFOS was detected above the calculated RSL in surface soil and below the calculated RSL in subsurface soil. PFOA was detected in surface soil at concentrations below the calculated RSL and was not detected in subsurface soil. PFBS was not detected in surface or subsurface soil.

Perimeter Road Fuel Spill: AFFF was sprayed from crash fire trucks onto a fuel spill associated with an overturned tanker trunk on the southeast side of Perimeter Road. No PFOS, PFOA or PFBS were detected in surface or subsurface soil.

Flightline Crash Areas: Cannon AFB Fire Department noted three separate crash areas along the flightline where AFFF was released during crash response activities. No soil sampling was conducted relative to the crash sites. Results of groundwater monitoring from locations downgradient of the crash sites is summarized below.

Basewide Groundwater: Groundwater was evaluated for all identified AFFF release areas; however, since groundwater at Cannon AFB is regulated basewide by NMED rather than specific to individual areas of

concern, a separate AFFF release area (Release Area 14) was identified for evaluating the presence of PFAS in basewide groundwater. PFOS, PFOA, and/or PFBS were detected in groundwater at 11 existing basewide monitoring wells. PFOS, PFOA and PFOS+PFOA exceeded the USEPA HA value (0.07 µg/L) in six monitoring wells; MW‐Ga and LF25‐MW‐Pa located southeast of the sewage lagoon area; and at monitoring wells MW‐Ca, MW‐D, MW‐Sa and MW‐Ta located in the southeast corner of the installation.

Primary Release Pathways: Release or application of AFFF to the ground at potential source areas. Infiltration of PFAS deeper into the soil column over time and reaching groundwater.

AFFF washed into drainage, stormwater, and sewer systems. Secondary Release Pathways: Irrigation utilizing water from the WWTP.
