The Team

The Initial Challenge

To provide technical support to the City of Berlin on what remediation would be necessary to convert land originally used as a poultry plant to a recreational area.

The Methods

The Town was interested in partnering with Thriving Earth Exchange to undertake microbiological risk assessment of the ponds at the site. Allen was reliant upon the scientists to come up with a testing method that would best determine the pond biology. Because they were both volunteers, the idea was that their objectivity would not be tarnished and the town could not be accused of taking any particular line of action.  The Town also contracted with EA Engineering, Science and Technology, Inc. PBC (EA) for a geotechnical review of the ponds and a remediation cost estimate.

Silbergeld used resources from microbiological assessment from Johns Hopkins’ lab. She received ancillary support from Salisbury – microbiological assessment, DNA analysis. There they ordered a kit that has a number of assays – used only 4 of them. She considered it good practice for her students. Tools and kits and her time – all of that fell under her lab development. Her own time and resources dedicated to it. She was familiar with the assays and techniques, so it wasn’t a stretch to do DNA isolation.

The scientists were able to collect sediment core samples for DNA extraction of DNA with the support of the town’s consultants, EA.

From the town’s end they had a number of resources from the wastewater facility and lab. Additionally, they partnered with Silbergeld to do some of the testing. Silbergeld also partnered with EA on extraction and nature of extraction/sediment samples. Ultimately, these facilities worked more with Nyland. The facilities coordinated on geotechnical analysis to get what Nyland needed.

The Results

As per the initially planned deliverable, the team produced a microbiological analysis of sediment sampling of one area within one pond of this facility. The results of the Thriving Earth Exchange study show that there are no microbiological hazards. For the Town, it means they don’t need to take immediate steps to remediate the ponds or even remediate it at all. EA indicated  it would cost approximately  $7m to remediate the three ponds.

In addition to the sediment sampling, the team also had the idea of holding a community meeting. However, with the delays in scheduling and development of other reports it eventually didn’t make much sense. Allen tried to coordinate a presentation to the Town Council, Mayor and Public and Parks commission in an order that made sense. Originally, the idea was to have a stand-alone community meeting with EA and Silbergeld. By early spring and summer of 2017, when other reports related to the property (building renovation and interpretive plan) came through, it became less attractive to have a separate community meeting focused on the ponds.

The Town of Berlin will use the microbiological analysis of sediment sampling of one area of one pond of the facility to demonstrate that there is no microbiological hazard in the ponds. If the council and public decide they want to remediate ponds, EA determined there is a tremendous amount of sediment in middle pond which will make it difficult to use it for kayaking or water sports. The town will need to  remediate the middle pond. However, the results of this report provide justification for not needing to immediately investment in the ponds. Therefore, between EA’s and the Thriving Earth Exchange project report, there’s no issue unless the middle pond is going to be used for water sports.

The Town Administrator and the community at large have a better understanding of the type of risks the ponds pose. Thus, the community should feel more comfortable  about using  the ponds. Considering the volunteer time spent, and work done through Thriving Earth Exchange, the report helps the town to provide justification for not spending the recommended $7-8m to remediate the ponds. Even if the town decides to take the EA information and remediate the first pond (estimated to be $2.3m), there isn’t an immediate health and safety reason remediate the pond. Thriving Earth Exchange bought them time to plan and figure out how to pay for remediation without having to treat it as a crisis situation.


From this project, others may learn better ways to partner with Thriving Earth Exchange for their own purposes. For instance, getting the team as committed to a scope early on and together – be it via phone or in-person regularly – early on. If a project decides to replace a scientist, ensure that it is done with the consent of the community leader and early on to ensure that all have sufficient buy in. As a scientist, if you are planning to hand off a critical piece of the project to someone else, ensure that you first have a discussion with the community leader you’re collaborating with first.

Communication is critical during all stages of the project. From the experience of the Town Administrator, it is very easy to work with Thriving Earth Exchange but community leaders need to be very clear about their expectations and what the community needs are. In the case of Berlin, if the Town Administrator had known about Thriving Earth Exchange’s existence prior to hiring the consultants, she would have preferred to have the Thriving Earth Exchange scientists do their work before getting consultants.

El equipo observó que lo siguiente contribuyó al éxito del proyecto:

  • Regular contact
  • Common interest in trying to solve a problem. Everyone was interested in helping.
  • Level of investment on part of Thriving Earth Exchange, Thriving Earth volunteer, etc.
  • In-kind contributions from associated scientists.
  • Trust associated scientist had in Thriving Earth scientist to be able to take on the project when requested.
  • Thriving Earth scientist provided clarity of associate’s role in the project.

Sin embargo, hubo varias cosas clave que el equipo haría de forma diferente si tuviera la oportunidad de repetir el proyecto:

  • More regular contact with Thriving Earth scientist; to ensure that the volunteer’s sense of continuity is not lost.
  • Community leader would ensure that she had more regular email contact with the Thriving Earth scientist so that person knew she had not been forgotten.
  • Better focus.
  • Clear understanding of the timeline at the outset.
  • More regularly scheduled meetings. It is important to connect and maintain that connection among team members so as to ensure it’s a viable team. Taking a pause and regrouping is not most efficient and effective way to keep the momentum.
  • From the volunteer’s perspective, if s/he doesn’t hear from the community at regular intervals, it becomes a less meaningful experience.
  • For this particular project, the town would have waited to contract with EA – since they could not address biological hazards – until someone could do the scientific analysis. In retrospect, if the Town had known about Thriving Earth Exchange sooner, they would have preferred to work with Thriving Earth first.

A otros equipos que actualmente llevan a cabo proyectos de Intercambio para una Tierra Próspera y a los que prevén realizar un proyecto de Intercambio para una Tierra Próspera, el equipo les recomienda:

  • Connect more regularly! Make sure you have open and clear lines of communication. There is benefit in spending even a little more time on a regularly scheduled phone call meeting even while work is happening off site. It makes it easier when work picks back up.
  • Be prepared for scheduling challenges. Scientists have a lot of other things they’re doing; they’re volunteers. They’re tapping into their available time. They’re busy people.
  • Reach out to Thriving Earth Exchange staff. Particularly, if things aren’t going as per your schedule. Thriving Earth Exchange is the intermediary and a sounding board.

El futuro

Along with this final report from the Thriving Earth Exchange team, three other reports went to Berlin Town Council on 28 August 2017.  The Thriving Earth Exchange report was well received.  Parks Commission meeting on 5 Sept. Focus will mainly be on what can they do with ponds, do they have to spend money? Building is expensive, what will they do. Don’t think it will cause them to do anything substantially different.

The Town of Berlin will assess whether to move forward with making the ponds a recreation area given the evidence received through the Thriving Earth Exchange and other reports. Should remediation be necessary, the Town now has some concrete ways forward.



El desafío

The Town of Berlin, MD has purchased approximately 60 acres of private property located at 9943 Old Ocean City Boulevard.  The property was previously owned by Tyson Chicken, Inc. and contains a chicken processing plant which has not been in use for over 10 years.  The Town intends to redevelop the land with recreational uses in mind.

Berlin completed a Phase 1 and Phase 2 environmental study on the property as part of its due diligence, posted on the town’s websiteE.coli was found in the ponds, with the possibility of other contaminants.  Therefore, the Town is interested in remediating the ponds and designing them in a way that minimizes the presence of E.coli. The expectation is that this remediation and design would reduce health risk and maintenance costs.

Acerca de la Comunidad
