Drinking Water Report

The health and well-being of Sailors, their families and civilians are the Navy's top priority.

NAS Kingsville's drinking water systems comply with all applicable Federal, State, and local safe drinking water regulations, Executive Orders, and Navy Policy by performing water quality monitoring and providing customers an annual Consumer Confidence Report as well as investigating and resolving customer complaints.

All these programs are designed to ensure that safe drinking water is delivered to every consumer.  Here are the latest Consumer Confidence Reports.

What are per- and polyfluoroalkyl substances and where do they come from?
Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of man-made chemicals. PFAS have been used in a variety of industries and consumer products around the globe, including in the U.S., since the 1940s.  PFAS have been used to make coatings and products that are used as oil and water repellents for carpets, clothing, paper packaging for food, and cookware.  They are also contained in some foams (aqueous film-forming foam or AFFF) currently used for fighting petroleum fires at airfields and in industrial fire suppression processes. PFAS chemicals are persistent in the environment and some are persistent in the human body – meaning they do not break down and they can accumulate over time.
Is there a regulation for PFAS in drinking water?
On April 10, 2024, the US EPA established MCLs for a subset of PFAS chemicals.

Chemical Maximum Contaminant Level (MCL)
PFOA 4.0 ppt
PFOS 4.0 ppt
PFNA 10 ppt
PFHxS 10 ppt
HFPO-DA (GenX chemicals) 10 ppt
Mixture of two or more: PFNA, PFHxS, HFPO-DA, and PFBS Hazard Index of 1
 

 
EPA requires implementation of sampling in accordance with the new MCLs within three years of the publication date and implementation of any required treatment within five years.
These limits did not apply for the 2023 calendar year because they had not been published. However, the DoD proactively promulgated policies to monitor drinking water for PFAS at all service owned and operated water systems at a minimum of every two years. The DoD policy states that if water sampling results confirm that drinking water contains PFOA and PFOS at individual or combined concentrations greater than the 2016 EPA health advisory (HA) level of 70 ppt, water systems must take immediate action to reduce exposure to PFOS or PFAS. For levels less than 70 ppt but above the 4 ppt level (draft at the time of policy publication), DoD committed to planning for implementation of the levels once EPA’s published MCLs take effect.
 
 
Has NALF Orange Grove tested its water for PFAS?
Most recently, samples were collected from NALF Orange Grove in February 2024.   We are pleased to report that drinking water testing results were below the Minimum Reporting Level (MRL) for all 29 PFAS compounds covered by the sampling method, including PFOA and PFOS.  The results are provided in the attached results report.  This means that PFAS were not detected in your water system.  In accordance with DoD policy, the water system will continue to collect semi-annual samples for PFAS until results are below the MRL for two consecutive sampling events and then every two years for your continued protection.
