Michael, a sincere thank you, to you, Mark, and your team. At least 5 others (consultants) blew me off before you guys came through for me. Mark was wonderful to work with. He was diplomatic and patient with the County folks and their processes. And he easily coordinated and worked with the guys from J&J Environmental. He was professional and kept me informed as I anxiously pushed for the next steps. I hope you guys continue to fund work in Calvert County. You have my recommendation. Best in the future.

As the developer of Howard County’s two largest private septic communities (Walnut Grove and Walnut Creek), I would give the Hydro-Terra team an A+ for their design assistance. These two systems support 235 homes. I have worked with Mike Haufler and his team for over 15 years, including years predating the formation of Hydro-Terra. The entire team collaborated in creating a system that was cost effective, plausible for review by state and local agencies, and truly innovative in a number of ways. To date, these systems set the bar for Howard County and would undoubtedly be ahead of their time for the entire State of Maryland.

Hydro-Terra has been a great partner on two of my commercial projects that are on shared Well and Septic systems. They are very knowledgeable about creative, cost effective solutions that perform to standards. Hydro-Terra knowledge of  the regulatory process is indispensable and they are well respected within the government agencies. They have been a great part of our projects success.

Over the past 25 years, I have worked with Mike Haufler and Jeff Lindaw on many ground water and environmental drilling projects, throughout Maryland and Pennsylvania. Hydro-Terra Group are experts in Hydrogeology. I have and will continue to refer Hydro-Terra for their professional services.

Hydro-Terra has been faithfully serving our water utility for over 25-years. Their staff’s knowledge and expertise has made them our one-stop shop for all things pertaining to wells and groundwater resources.  We look forward to continuing the relationship.

HTG really prepares exceptional technical drawing and engineering packages. You guys should be proud of the work you do and the service you provide to your customers. I have the unique opportunity of reviewing a lot of engineering work prepared by consultants from all parts of the United States and your technical skills, understanding of wastewater engineering, and knowledge of on-site disposal establish a standard that others should follow. Keep up the good work and I am sure your customers are very pleased with your service and experience.

We appreciate the diligence and hard work of Hydro-Terra in assisting us in closing out our underground storage tank remediation project. It was a pleasure working with them.
