ABSTRACT
Background
In the United States, problems with the provision of safe, affordable water have resulted in an increasing number of adults who avoid their tap water, which could indicate underlying water insecurity. Dietary recalls provide critical nutritional surveillance data, yet have been underexplored as a water insecurity monitoring tool.
Objectives
This article aims to demonstrate how water intake variables from dietary recall data relate to and predict a key water insecurity proxy, that is, tap water avoidance.
Methods
Using 2005–2018 NHANES data from 32,329 adults, I examine distributions and trends of mean intakes of total, plain (sum of tap and bottled water), tap, and bottled water, and percentage consuming no tap and exclusive bottled water. Second, I use multiple linear and logistic regressions to test how tap water avoidance relates to plain water intake and sugar-sweetened beverage (SSB) consumption. Next, I use receiver operating characteristics (ROC) curves to test the predictive accuracy of no plain water, no tap, and exclusive bottled water intake, and varying percentages of plain water consumed from tap water compared with tap water avoidance.
Results
Trends indicate increasing plain water intake between 2005 and 2018, driven by increasing bottled water intake. In 2017–18, 51.4% of adults did not drink tap water on a given day, whereas 35.8% exclusively consumed bottled water. Adults who avoided their tap water consumed less tap and plain water, and significantly more bottled water and SSBs on a given day. No tap intake and categories of tap water intake produced 77% and 78% areas under the ROC curve in predicting tap water avoidance.
Conclusions
This study demonstrates that water intake variables from dietary recalls can be used to accurately predict tap water avoidance and provide a window into water insecurity. Growing reliance on bottled water could indicate increasing concerns about tap water.

What flow rates are available for emergency water treatment?
AMPAC USA's emergency systems range from 1,500 GPD portable units to 50,000+ GPD trailer-mounted systems. Military-specification units are available for forward operating base deployment, producing potable water meeting EPA and WHO drinking water standards from virtually any source.
Are emergency RO systems suitable for disaster relief operations?
Yes. AMPAC USA's emergency systems are used by FEMA, the U.S. military, and international NGOs for disaster relief. They treat flood water, contaminated groundwater, and brackish sources, removing bacteria, viruses, and chemical contaminants to produce safe drinking water on-site.
What power sources can emergency water purification systems use?
AMPAC USA's emergency systems can run on generator power (120/240V or 480V 3-phase), solar panels with battery backup, or vehicle power take-off (PTO). Low-power models consume as little as 0.5 kW, making them viable for off-grid deployment.
How durable are military-grade water purification systems?
AMPAC USA's military systems are built to MIL-SPEC standards with stainless steel frames, powder-coated components, and UV-resistant materials. They are designed to operate in temperatures from -20°F to 120°F and are vibration-tested for transport in military vehicles.
Conclusion
This post highlighted how emergency and military-grade water purification systems provide safe drinking water rapidly in the most challenging field conditions. For organizations requiring deployable water treatment capability, AMPAC USA engineers portable and trailer-mounted systems built to perform wherever they are needed.

Water Insecurity Dietary Recall Data United States: Technical Analysis and Solutions
Water insecurity—defined as the inability to access sufficient, safe, affordable water—affects millions of Americans, not just in rural areas but in urban communities with aging infrastructure, contamination, or cost burdens. Research using National Health and Nutrition Examination Survey (NHANES) dietary recall data to identify proxy measures for water insecurity provides new insights into the distribution and determinants of water access disparities, informing both policy interventions and targeted water treatment deployment.
Understanding the science behind water quality challenges in this area enables selection of appropriately engineered treatment solutions. Water treatment technology selection should be based on comprehensive source water analysis, contaminant characterization, and performance-verified system design.
Reverse osmosis systems from AMPAC USA provide multi-contaminant treatment capability through TFC polyamide membranes achieving 90–99% rejection of dissolved contaminants, combined with sediment pre-filtration, activated carbon treatment, and UV disinfection options. Our commercial and industrial systems are NSF/ANSI certified, providing documented performance evidence for regulatory compliance and quality assurance programs.
For specific water quality challenges in this application area, AMPAC USA’s engineering team provides source water analysis review, system sizing recommendations, and complete treatment train design to ensure water quality objectives are reliably achieved.

Frequently Asked Questions
What is reverse osmosis water purification?
Reverse osmosis forces water under pressure through a semi-permeable membrane (0.0001 µm pores) that rejects 90–99% of dissolved contaminants while allowing pure water molecules to pass through. It is widely considered the most effective point-of-use water treatment technology.
What contaminants does reverse osmosis remove?
RO removes dissolved salts (TDS), heavy metals (lead, arsenic, chromium), nitrates, fluoride, PFAS, pharmaceuticals, bacteria, viruses, and most organic contaminants through a combination of size exclusion, charge repulsion, and hydrophobic rejection mechanisms.
How does water quality affect public health?
Access to safe, clean drinking water is fundamental to human health. Contaminated water causes an estimated 500,000 diarrheal deaths annually worldwide and contributes to chronic health conditions through long-term exposure to heavy metals, nitrates, PFAS, and other regulated and unregulated contaminants.
When should I consider a water purification system?
Consider water purification if your water has detectable lead, nitrates, arsenic, PFAS, or other contaminants; if you have a private well; if your water tastes or smells off; if you have immunocompromised family members; or if you want to reduce your dependence on bottled water.
What is the difference between water filtering and water purification?
Filtration physically removes particles and some dissolved compounds from water. Purification (including RO) achieves more comprehensive removal of dissolved contaminants through pressure-driven membrane separation. RO is considered purification because it removes dissolved ionic species that filtration alone cannot address.
How often does a water purification system need maintenance?
Reverse osmosis systems require pre-filter replacements every 6–12 months, membrane replacement every 2–5 years, and annual system sanitization. Well-maintained systems provide consistent, high-quality water for 10–15+ years with these routine service intervals.
Does AMPAC USA offer water treatment systems for this application?
Yes. AMPAC USA provides residential, commercial, and industrial water treatment systems including reverse osmosis, UV disinfection, and multi-stage treatment solutions designed for specific water quality challenges. Our systems are NSF/ANSI certified for performance verification and customer confidence.
