Soto Cano Air Base (aka Joint Task Force-Bravo)


The Army is committed to ensuring quality drinking water is provided to its Soldiers, family members, and civilians. Proactive sampling is performed by the Army on its drinking water systems and coordination with other purveyors of drinking water to installations occurs to ensure PFOS/PFOA remains below the Environmental Protection Agency’s lifetime health advisory level of 70 parts per trillion (ppt) for PFOS and PFOA (individually or combined). While not an enforceable regulatory standard, a lifetime health advisory represents a concentration in drinking water that is not expected to produce adverse health effects if the water is consumed over an entire lifetime.

Status: Bottled water is the main source of drinking water at Soto Cano Air Base; however, local water is used in the dining facility and has been placed on a carbon filter.  The Army will continue to sample and monitor the  water in the dining facility to ensure the EPA lifetime health advisory levels are not exceeded.  

PFOA + PFOS Results:  2.1 parts per trillion (ppt) in finished drinking water

Test results date:  December 2022

Testing Frequency:  quarterly

Future Testing Event: June 2023

History: As a proactive measure between 2016-2017, the Army tested  the drinking water wells at Soto Cano Air Base for PFAS and found no exceedance of the EPA lifetime health advisory levels.  However, a water holding tank was also tested and the test result  (83 ppt) showed an exceedance of the EPA lifetime health advisory. Bottled water was provided.   A carbon filter was installed for the dining facility, which will continued to be sampled.

Type of drinking water systems:  Army-owned
