Daniel L. Theobald or Wastewater Dan was coming into our operation when we’re not complying with our zinc level. We were out of compliance for several years and despite our best efforts, we could not get into compliance. Dan has given several suggestions and we have put them into place. As a result, we have been over 6 months free of exceedances. We also have been able to eliminate two waste water, chemicals we were using. We also lowered our chemical usage. We have seen a huge cost saving and operational savings.

I can say if you have problems, call Dan. He will get you fixed in a hurry.

Daniel has been an integral part of our Wastewater management program for several years, beginning before I was employed at Carolina Pride. In my time working with Daniel, I have found him to be a knowledgeable, thorough, professional who serves a vital function of our organization. And, when we had a critical employee leave the company, Daniel was able to assume part of those duties so we could continue to operate safely within the regulations. He suggested and we installed and are utilizing specific pieces of testing equipment for better monitoring and therefore more efficient usage of the necessary wastewater chemicals. And while he is most knowledgeable in wastewater management, he has experience in other environmental matters and we have utilized him as part of our overall environmental program.

I would highly recommend Daniel’s work to whomever is in need of professional advice or support for their wastewater or other environmental needs.

He developed relationships with the operators on all three shifts and provided daily feedback on our process status. He also provided monthly reports on discharge data and helped resolve any laboratory result discrepancies. Dan had good insight on process improvements and was a pleasure to work with.
