And she didn't attempt to access private systems.
Instead, she used lawful observations, public information, and the technical data available through the investigation.
Some evenings, the bubbling began shortly after a distant mechanical hum became audible from the northern ridge.
Other times, the pond remained quiet.
Claire cautioned her that sound and water movement alone couldn't establish the source.
Industrial equipment operated for many reasons.
Natural groundwater systems could produce delayed responses.
And a correlation might disappear when more measurements were collected.
Naomi understood.
So she focused on consistency.
Dates.
Times.
Water levels.
Weather.
And observations from fixed locations.
She also arranged for qualified personnel to install appropriate monitoring equipment where the ground was stable.
As the data accumulated, a pattern emerged.
Certain changes in pond level and underground pressure appeared to occur repeatedly during periods associated with activity near the northern excavation.
Claire compared those measurements with historical records and the available quarry information.
The relationship was not simple.
There were delays.
Variations.
And several days when the expected pattern didn't appear.
But the combined evidence was strong enough to justify a more detailed investigation.
Claire prepared a preliminary technical memorandum.
Then submitted the relevant findings to the appropriate environmental and water-resource authorities.
Naomi felt relieved.
At last, the concern existed beyond her notebook.
The investigation created tension with Dale's neighbors.
Several people in Halbert County worked at Ridgeline Materials.
The quarry paid decent wages by local standards.
It supported trucking businesses, equipment suppliers, and contractors.
Some families depended on the operation.
When rumors spread that Naomi believed the quarry was damaging her pond, people began arguing.
A few praised her for raising the concern.
Others accused her of trying to shut down an important employer.
Otis was caught in the middle.
His younger brother worked at the quarry.
One evening, Otis approached Naomi near the barn.
He looked uncomfortable.
"Can I ask you something?"
She nodded.
"Sure."
"Are you trying to get the place closed?"
Naomi looked surprised.
"No."
He sighed.
"That's what folks are saying."
She leaned against the fence.
"I'm trying to find out why my pond is rising during a drought and why the bank is collapsing."
Otis nodded.
She continued.
"If the quarry isn't responsible, the evidence should show that."
He considered that.
"And if it is?"
Naomi looked toward the distant hills.
