How Hexivon and Hillwood are building the infrastructure to solve PFAS contamination in the water supply— permanently
There is a quiet crisis running through the pipes of American cities. It has no colour, no smell, and no taste. You cannot see it in a glass of water or detect it without specialised laboratory equipment. But it is there — in the drinking water of communities across every region of the United States — and it has been accumulating for decades.
PFAS — per- and polyfluoroalkyl substances — are a class of more than 12,000 synthetic chemicals used in industrial manufacturing, consumer products, and military firefighting foam since the 1940s. They were engineered for permanence: heat-resistant, water-resistant, and chemically stable. The same properties that made them useful in Teflon cookware, food packaging, and stain-resistant clothing make them extraordinarily dangerous in the environment. PFAS do not break down. They accumulate in soil, water, and human tissue — earning them the name “forever chemicals.”
The scale of contamination is staggering. The Environmental Working Group has identified more than 9,500 contaminated sites across all 50 states. An estimated 200 million Americans are exposed to PFAS through their drinking water. Over 700 military installations are contaminated from decades of aqueous film-forming foam — AFFF — used in firefighting. And the contamination is not historical. It is ongoing, and it is getting harder to ignore.
The regulatory reckoning
For years, PFAS contamination was treated as an emerging concern — important, but not yet regulated. That changed in April 2024, when the United States Environmental Protection Agency finalised the first-ever Maximum Contaminant Levels for PFAS in drinking water. The MCL for PFOA and PFOS — the two most studied and most prevalent PFAS compounds — was set at 4 parts per trillion. To understand how small that number is, consider that 4 parts per trillion is equivalent to four drops of water in an Olympic-size swimming pool.
The rule is not advisory. It is federal law. Water systems serving more than 25 people must comply by 2029 — a deadline that may sound distant but is, in practical terms, already here. Designing, procuring, permitting, and constructing a water treatment system takes years. Communities that are not actively moving toward compliance today will find themselves facing enforcement action, federal penalties, and significant public health liability in the years ahead.
More than 1,300 water systems across the United States have already been identified with PFAS levels above the new MCL. In Texas alone, dozens of public water systems in the Dallas-Fort Worth region have recorded detections at or above the federal limit. These are not failing systems or neglected utilities — they are communities that inherited a contamination problem created by industry and military activity over the course of generations. And they are now being asked to solve it.
The problem with existing solutions
The conventional response to PFAS contamination has relied on two primary technologies: granular activated carbon filtration and reverse osmosis membrane systems. Both are widely deployed, well-understood, and regulatory-compliant. And both share a fundamental flaw: they do not destroy PFAS. They concentrate it.
Activated carbon captures PFAS molecules on a porous carbon medium — but the carbon eventually saturates. When it does, it must be replaced and disposed of as hazardous waste. The PFAS problem has not been solved; it has been transferred to a landfill or incineration facility. Reverse osmosis concentrates PFAS into a reject stream that must also be managed, transported, and disposed of — creating secondary contamination liability that communities inherit along with the filtration system itself.
The water treatment industry has known this for years. What it has lacked is an alternative — a technology capable of achieving what filtration cannot: complete, permanent destruction of PFAS at the molecular level, without creating a secondary waste stream that perpetuates the contamination cycle. That technology now exists.
Hexivon: elimination, not filtration
Hexivon is a Dallas-based water technology company built around a single, uncompromising mission: the complete elimination of PFAS from water — not its reduction, not its relocation, but its permanent destruction. The company’s core technology is a three-stage mineralisation process that breaks PFAS compounds down at the molecular level, severing the carbon-fluorine bonds that make them persistent and producing no toxic byproduct in the process.
The process works in continuous flow. Contaminated water enters the Hexivon Collection stage, where PFAS molecules are captured and concentrated from the water stream. The concentrated stream moves to the Water Stripping stage, where PFAS compounds are separated from the water matrix. In the final stage — Mineralisation — PFAS molecules are destroyed at the molecular level. The carbon-fluorine bonds that define forever chemicals are broken permanently. The water that exits the system is clean. There is no spent carbon, no PFAS concentrate, no secondary waste stream.
Critically, the process operates at ambient temperature and pressure — a meaningful operational advantage over energy-intensive alternatives. Lower energy requirements translate to lower operating costs and simplified infrastructure integration, making the system practical for the range of system sizes municipalities actually operate.
The technology has been validated in the field. At a Raw Water Pump Station in North Carolina — a state where Hexivon has built deep relationships and operated for many years — Hexivon’s system processed 150,000 gallons of drinking water per day — continuously — taking water contaminated at 40 parts per trillion and delivering a non-detectable result. That is not a laboratory result. It is a documented, third-party-verifiable outcome from an operational deployment in a real water system. That system has since been scaled: Hexivon’s first revenue-generating deployment is a 1.4 million-gallon-per-day system at a textile mill in South Carolina, operating under the company’s Planet Clear sub-brand for land reclamation and industrial water management.
The partnership that changes the scale question
Technology alone does not solve a national infrastructure problem. Solving PFAS contamination at the scale the crisis demands requires capital, relationships, and deployment infrastructure. It requires partners who understand how communities make decisions, how infrastructure gets financed, and how trust gets built with municipal decision-makers who are accountable to their residents.
In June 2026, Hexivon announced a strategic partnership with Hillwood, the real estate and infrastructure development company founded by Ross Perot Jr. Hillwood is one of the most significant real estate and development enterprises in North America — a firm with deep roots in Texas infrastructure, proven experience navigating complex municipal relationships, and a track record of deploying capital at scale in communities across the region.
The partnership is strategic in the truest sense. Hillwood brings the credibility, relationships, and infrastructure intelligence that accelerates deployment in markets where trust and community standing are prerequisites for progress. Hexivon brings the only technology on the market capable of permanently eliminating PFAS from water. Together, they are building a go-to-market model in the Dallas-Fort Worth region — the prototype for how this problem gets solved across the country.
The DFW market is the right place to start. The region has dozens of water systems with PFAS detections at or above the EPA MCL. It is home to the infrastructure, engineering, and financial ecosystem capable of supporting rapid deployment. And it sits at the intersection of two converging pressures: a federal compliance deadline that is now within sight, and a state grant program — Texas House Bill 500 — that has put $1.038 billion in 100% grant funding on the table for water supply and infrastructure improvements, with a July 30, 2026 application deadline.
A model built to scale
Hexivon is not building a DFW company. It is building a global company using DFW as its proving ground. The company operates through five specialized sub-brands — Blue Future Water for municipal drinking water, ZeroSign for wastewater management, PureAfter for industrial water, Planet Clear for land reclamation, and Mineral Command for military and government AFFF remediation — each designed to address a distinct segment of the PFAS contamination landscape with purpose-built technology and deployment frameworks.
The global market opportunity is significant. PFAS contamination does not respect borders. The same crisis playing out in DFW is playing out in New Jersey, Michigan, North Carolina, Florida, California, and communities in every region of the world. The EPA’s 2029 compliance deadline applies nationally, and similar regulatory frameworks are emerging internationally. The pressure on municipal water directors, public works officials, and elected leaders to find a solution — a real solution, not a temporary filtration measure — is building everywhere at once.
Hexivon’s technology is modular and scalable, deployable across a wide range of system sizes — from small municipal utilities to large-scale industrial and military applications. The partnership with Hillwood provides the capital and relationship infrastructure to accelerate that deployment in markets where Hexivon’s track record, Hillwood’s community standing, and the urgency of the compliance deadline converge.
The goal is not simply to deploy systems. It is to establish a new standard for how the water industry addresses PFAS — one built on elimination rather than filtration, on verified proof points rather than marketing claims, and on community partnership rather than vendor relationships. The science is proven. The technology is deployed. The partnership is in place. What comes next is scale.
The moment is now
America’s PFAS crisis did not develop overnight, and it will not be resolved overnight. But the tools to solve it — permanently — now exist. The regulatory framework is in place. The funding mechanisms are open. The technology is proven and deployed. What the crisis has lacked, until now, is a partnership model capable of bringing elimination technology to communities at the speed and scale the moment demands.
The Hexivon and Hillwood partnership is that model. It is built on the conviction that the right answer to a forever problem is a permanent solution — and that the communities affected by PFAS contamination deserve exactly that. Not a filter. Not a workaround. Not a transfer of the problem from one location to another. Elimination.
We don’t reduce PFAS. We eliminate it.
