Our Customers

  • "I am confident in the integrity of Cotey Chemical Corp. and trust their products."
    John Bonsangue, R.G.
    Orange County Water District
  • "We've recently constructed an 8" municipal well that produced 80 GPM - 500' depth. During the grouting, approximately 70 bags of cement ended up in the well and blocked all water from entering the well. We used Dry Acid Special three weeks after grouting and restored yield to 80 GPM. Valley Drilling Corporation of Virginia will be using Cotey Chemical products for all well cleaning."
