Analysis may be required to confirm Waste Stream products.

It is up to the producer / waste generator to characterize and classify their waste streams. Descriptions and product will be subject to audit by Four Winds at the time of receipt to confirm compliant by both parties.

* Brine equivalent – Aqueous salt solutions that are equivalent to produced water by comparison to Production Fluids
