A federal case just dropped a match into a question some Hillsboro residents have been avoiding for years:
Who decides what gets poured into the pipes beneath our feet?
On January 21, federal prosecutors announced that Kayla Hartley, 35, of Troutdale, pleaded guilty to conspiracy to violate the Clean Water Act—a case tied to a Hillsboro operation that prosecutors say accepted and discharged roughly 500,000 gallons of industrial wastewater into Hillsboro’s sanitary sewer system. Clean Water Services- the rogue billion-dollar sewer and water agency in Washington County is once again in the middle of controversy.
KEY POINT: The Poison Was Horrific: The Justice Department says the waste contained pollutants, including hydrofluoric acid and metals such as arsenic, as well as titanium, molybdenum, vanadium, and other heavy metals.
Prosecutors also say that when Clean Water Services (CWS) staff visited the facility, Hartley attempted to conceal that industrial wastewater was being discharged.
Hartley is scheduled to be sentenced on May 12, 2026, and faces a statutory maximum of five years in prison, a $250,000 fine, and three years of supervised release.
That’s the headline. But we do not stop at the headlines- no, my friends. That is no fun at all and we are not interested in feeding you all more pablum like other sound bite media sources do.
Here’s what locals should understand: half a million gallons doesn’t happen by accident.
That volume isn’t a single bad night. It’s a routine. It’s paperwork. It’s pricing. It’s hauling. It’s scheduled drop-offs. It’s a chain of custody with fingerprints all over it. And yet, as usual, the public narrative is being squeezed into something convenient: one defendant, one plea, case closed.
No.
This story isn’t just about who gets punished. It’s about who gets protected.
The question the public deserves to ask out loud – Where Are The Source Polluter And Clean Water Services In All Of This?
Federal prosecutors say the operation was marketed as able to accept and dispose of industrial wastewater despite lacking the required permit or authorization to discharge that kind of waste.
Read that again: no permit or authorization.
So the question isn’t “how did she do it?” The question is:
How does an operation run long enough to discharge half a million gallons into a public system without someone upstream stopping it?
Where was the gate?
Who was responsible for checking it?
And if the gate exists only on paper—what exactly are we paying for?
Clean Water Services: What did you verify, and when?
I think you all know by now that I believe and have provided plenty of proof that Clean Water Services is not a well-run agency. This near-billion-dollar entity has been out of control for years, and the executives have run wild on trips and 5-star hotels all over the globe. CWS is not some distant agency. CWS runs the sewer and stormwater systems in Hillsboro and most of Washington County. It also administers the industrial pretreatment and discharge program—the system specifically designed to prevent this exact scenario: industrial chemicals entering public sewer infrastructure, harming equipment, threatening worker safety, and compromising treatment processes.
DOJ says CWS staff visited the facility, and Hartley allegedly tried to conceal the discharge activity.
That means the system touched the problem.
So here are the questions CWS should answer publicly—without PR varnish:
Did CWS ever issue any permit or authorization to this facility?
If not, what did the facility present to customers that made it appear legitimate?
When did CWS first learn that industrial wastewater was being accepted there?
What triggered the visit: a complaint, an odor, a tip, a flow spike, a lab flag?
After that visit, what enforcement happened, and what didn’t?
If the discharge point was “not designated,” as described in the federal case summary, how was that physically occurring—and for how long?
If the public can’t see the timeline, then the public is being asked to trust the timeline.
And “trust us” is exactly how systems fail—quietly, repeatedly—until the feds show up with a criminal indictment and everyone pretends they’re shocked. In this case, with CWS, this is all too much- the ethics and staff issues were enough. No, this is not ok at any level.
A bigger problem: the chain of custody
The Justice Department’s environmental case summary also identifies a major industrial source: Precision Castparts Corp. (PCC), which is described as discharging wastewater from etching titanium parts. The federal summary states the Hillsboro facility received about 500,000 gallons and discharged industrial wastewater without a permit.
Now ask yourself: do you think a load like that arrives without a paper trail?
Half a million gallons means contracts. Quotes. Hauler schedules. Waste profiles. Manifests. Receipts. Emails. Repeat business.
So the sharper accountability question is this:
Who generated the waste—and what did they verify before shipping it out the door?
Outsourcing waste handling isn’t rare. It’s common. But “we hired a vendor” isn’t a moral escape hatch when the waste includes hydrofluoric acid and heavy metals.
If a company can source ten signatures to approve a budget, it can demand a permit number and verify it.
So:
What documentation was requested from the receiving facility?
What waste profile and testing accompanied the shipments?
Who hauled it?
Who accepted it on arrival?
Who invoiced it?
Who signed off?
If those documents exist, they’re the real story.
If those documents don’t exist, we’ve got a deeper problem than a single guilty plea.
Why these chemicals aren’t a technicality
Hydrofluoric acid is not “dirty water.” It’s a hazardous chemical with well-documented acute risks. Arsenic isn’t a paperwork issue—it’s a toxic metal associated with serious long-term health hazards at sufficient exposure.
And here’s the point that gets lost in bureaucratic language: when those substances enter a public sewer system, they don’t disappear. They move. They burden a system. They put people at risk. They travel into processes and solids handling. They become someone else’s problem—often downstream and out of sight.
That’s why pretreatment exists.
Which brings us back to the question: who looked away long enough for this to become routine?
One plea doesn’t close a half-million-gallon hole
Hartley pleaded guilty. She will be sentenced. That’s what the public is being offered as closure.
But the volume in this case screams something else:
This wasn’t a one-person event. It was a chain.
And chains have links. So until the paperwork is public—until the timeline is visible—until the agency answers basic questions—this doesn’t end with one defendant.
It begins there.
What the Hillsboro Herald is requesting next
To clarify what happened—and how it was allowed to happen—this paper seeks:
CWS records: permits/authorizations, applications, inspection reports, sampling data, enforcement letters, internal communications, and a complete timeline of CWS contact with the facility during the relevant period.
Chain-of-custody records: hauling logs, manifests, waste profiles, acceptance letters, invoices, certificates of disposal.
Corporate structure documents: ownership/management relationships tied to the Hillsboro operation and any related entities referenced in federal summaries.
If you worked in hauling, treatment, permitting, compliance, or industrial discharge oversight—and you know how this works in practice—reach out. Documents matter. Timelines matter.
Half a million gallons is not a mystery.
It’s documentation.

Hasn’t Precisioncast Parts been in the news before for environmental bad behavior before?
Precision Cast Parts is in SE Portland. What is the facility in Hillsboro that did the actual dumping into Hillsboro’s sewers? I’m guessing the woman’s lawyer is getting information about who in her company told her to do this.
So we’re back to “Clean” Water Services. Now they can’t even keep the water clean. And Washington County commissioners have failed us — not just failed us again, but actually threatened our safety. How do we deal with this county government? Most of us feel helpless against the bureaucrats and the rich oligarchs behind them. And that’s true on national and more local levels as well.
Precision Cast Parts has had umpteen protests over their environmental, labor and war-making equipment for years. I remember protesting their equipment produced for war back in the 60’s, I think it was.
Thank you for delving into this and asking the right questions! There is much more to this story and I am eager to learn more after you get a response from Clean Water Services.
The company that did the discharge has a very sketchy past:
https://www.propublica.org/article/how-a-pg-e-contractor-with-a-sketchy-past-made-millions-after-californias-deadliest-fire
The discharge started in February 2020. When their environmental director came up from Oakland the week before they started he disappeared and was found frozen at a Mt. Hood Ski resort. The next month utility Giant PG&E announced the company was bribing PG&E employees and paying kickbacks related to waste disposal from the 2018 Paradise CA fire and cut their contracts with the dumping company which obviously created a cash crisis. Would they bribe PCC staff to get dumping contracts and then cut corners?
