Are you telling me that that was not just water, but there were polymers in that? Where are we with this dust suppression, and where do polymers fit in from a when did they start being used and, and are they commonplace or is this specialized cases or that kinda stuff?

First, to answer your question, back in the day when you were watching those water trucks drive around, it was just water.

And that's really still the standard in many places today.

Facilities will spray water on the ground on the surface in the hopes that that'll hold it down.

They'll repetitively run those water trucks all day long putting water on the ground.

And in our opinion, that's not a real efficient or effective way to manage dust because here in Texas, as you know, we live on the surface of the sun, and that water evaporates before it hits the ground many times.

No, to answer your question, probably they did not have polymer in a lot of those trucks.

Have you done any calculations or have any ballpark idea of using your polymer versus either water suppression or other polymers, what that water utilization side is?
