The addition of VPS’ certified mitigation services solidifies EnviroForensics’® commitment to providing top-notch services and solutions to its clients, and increases the probability of gaining a foothold in new markets.

EnviroForensics to Present at AEHS Conference

In a crucial time, when the need for innovative methods to protect the environment is at an all-time high, some of the top scientific authorities in the world will be gathering in Southern California to share their ideas. We are honored to be counted among the trusted names presenting at this year’s Annual International Conference on Soil, Water, Energy, and Air put on by the Association for Environmental Health and Sciences (AEHS).

As many as 600 participants are expected in San Diego for this week’s conference. Attendees are drawn from a variety of professions including state and federal regulatory agencies, environmental engineering and consulting firms, the petroleum and chemical industries, military, and academia.

This conference carries significance for those in the Vapor Intrusion industry because it hosts the U.S. EPA’s Vapor Intrusion Work Shop every year. The workshop is the ideal forum for the country’s chief regulators to bring consultants and engineers up to speed on the latest guidance for Vapor Intrusion detection and mitigation, and consequently draws some of the national leaders in this field of science. You’ll be able to watch this on a live-stream that is sponsored, in part, by EnviroForenics. Follow this link to register. 

The same people who will be attending this workshop will likely be in attendance for our presentation. Our Director of Vapor Intrusion and Risk Assessment, Megan Hamilton, and Project Manager, Casey McFall CHMM, will provide their expertise about Vapor Migration immediately following the EPA VI Work Shop on Tuesday, March 21st.

The presentation, entitled “New Insights into Exposure through Preferential Pathway Vapor Migration,” takes a deep dive into vapor intrusion migration and exposure and how some regulatory guidance on testing techniques may be lacking in their capability to elicit reliable results. The talk will also include an analysis of atypical preferential pathways, that if gone unchecked, could present exposure hazards. We will be presenting our findings based on real-world case studies we’ve gathered from 14 different project sites. We’re looking forward to unpacking those results and engaging with our fellow environmental professionals.

EnviroForensics presenting at international waste management conference this week

We are humbled to have some of the foremost minds in the Environmental Consulting industry right under our roof! Our staff boasts decades of experience, and the knowledge and wisdom to help move environmental science forward in a profound way. Our Director of Vapor Intrusion Services, Megan Hamilton, is one those individuals keeping us on the cutting edge, and she’ll be imparting some of that wisdom on an international stage this week!

Hamilton is headed to the Air and Waste Management Association’s Vapor Intrusion, Remediation, and Site Closure Conference in San Diego, California. This is the 8th specialty conference hosted by AWMA focused on the critical and changing area of Vapor Intrusion, and one of the few conferences in the world to focus on this particular exposure pathway.

Director of VI Services, Megan Hamilton, is presenting this week at the AWMA Vapor Intrusion, Remediation, and Site Closure Conference in San Diego, California.
Director of VI Services, Megan Hamilton, is presenting this week at the AWMA Vapor Intrusion, Remediation, and Site Closure Conference in San Diego, California.

Hamilton will be presenting a poster in the exhibit hall entitled, “The Cost and Liability of Evolving VI Technical Guidance.” The research for her presentation was a team effort with EnviroForensics Executive Vice President, Jeff Carnahan, LPG, and Professional Staff members Grace Randall and Kathleen Nazareth pitching in. This presentation evaluates how high levels of uncertainty and conservatism during the early years of VI regulation may have affected the exposure assumptions and costs associated with the investigation and mitigation of the VI pathway at remediation sites. In this study, a portfolio of sites consisting of nearly 40 subsurface releases of PCE or TCE have been reevaluated based on a series of guidance milestones since 2002.  Actual assessment and mitigation costs have been compared with those that would have been occurred if performed under older state and federal VI guidance, and the latest version of the Final U.S. EPA VI Guidance.

This week’s event is expected to draw internationally-recognized scientists, engineers, regulators, and attorneys with experience in getting sites to closure and focuses on the critical sustainability and technical issues that need to be considered in doing so.

Hamilton is no stranger to this kind of attention. She has presented at several national and international Environmental conferences, is a member of the National EPA VI Science Advisory Committee, and was just awarded a second term on the Board of Directors for the Midwestern States Environmental Consultants Association (MSECA). Her credentials in the area of VI speak for themselves; she oversees VI investigations and mitigations for all EnviroForensics projects, and she was the main author of the current Indiana Vapor Intrusion Guidance during her time at the Indiana Department of Environmental Management’s (IDEM) Office of Land Quality.

 

Ranking and Choosing Remedial Technologies

We are always looking for ways to better serve our clients when it comes to remediation design. After all, they rely on our expertise and command of chlorinated solvents to guide them through what could potentially be a very challenging chapter in their lives. Continually developing our abilities to think critically and make sound, confident decisions can go a long way towards choosing the best course of action.  Enter the EnviroForensics Colloquium series; a series of bi-weekly discussions held among our staff to facilitate discussion and learning regarding the topic for that session.

The most recent discussion focused on remediation design, and more specifically, how our teams go about choosing one remedial technology over the other. It’s a significant subject, since the client’s wishes are heavily considered during this process.

Ranking Remediation Design Approaches

Our technical staff utilize screening matrices that help the tech team rank the remedial approaches to a given project Site. Geological conditions are typically the first elements to be taken into account. Understanding the nature of the soil and how layers of rock or sediment stack up provides the starting point in determining the technology needed to reduce contaminant concentrations. There are some remedial applications that don’t have the effectiveness in certain types of soil or geological conditions.

Contaminant Conditions

Contaminant Conditions (the nature and extent of impact) are also an important consideration during remediation design. How much is in the soil and groundwater? And where is it traveling? How fast?  These answers can narrow down the options based on what technologies will be effective in treating the impact.

Land Usage

Land usage must also be assessed. What is the property’s use right now? How will it be used in the future? If it’s a business and it’s going to continue to be one, the cleanup strategy will be considerably less invasive and more labor intensive.  Cleanup standards are different for residential vs commercial land use.

Cost-Effective Approaches

We prioritize cost-effectiveness. Our aim as a company is to utilize a technology that will require the fewest resources while maintaining a high level of effectiveness.  Not hitting on either of these targets causes costs to rise.  We focus on our client’s needs and receive a fair amount of business through word of mouth.  We take great pride in that.

Timing

Which brings us to another important client –driven factor; timing. How quickly does the client need this project to be finished? And what kind of technologies can deliver the desired effects in that period of time? We want to be able to close out the project as quickly as we can: effectively remediating the contamination while keeping with the client’s needs.

Safety Concerns

Safety concerns can loom large for some technologies. A miscalculation on a subsurface injection or a slip of the wrist on the operating lever of a backhoe can pose serious threats to health and safety at the project Site. One of our core values here at EnviroForensics involves “contributing to a healthy community.” We like to practice what we preach, so if there’s a different, more safe method of remediation, we will always go in that direction.

Continual Learning

EnviroForensics provides this and many other training and learning opportunities for our staff at all levels.  Chlorinated Solvents are our specialty, and activities like these allow us to retain a high level of excellence in this niche. It should be noted we operate with a “we over me” mentality often collaborating in teams to ensure the client get the best service possible, and education is key for this to happen.  The colloquium series is a led discussion by our Chief Geologist or a different expert on a topic.  Attendees are provided materials to read or consider prior to the meeting.  We keep our eyes forward to stay on the cutting edge of technology and the most effective application of our skills.

Open House Reflects Heart and Soul of EnviroForensics

It was the continuation of what has been a very exciting year in the history of EnviroForensics. Thursday night, we welcomed more than 200 people through our doors at 825 North Capitol to get an up-close look at our brand new headquarters; the culmination of more than a year’s long effort to bring new life to an old costume warehouse and transmissions garage. True to form, EnviroForensics combined the celebratory activities with an opportunity to convey an important message of environmental and human rights awareness.

The event began with an important discussion about clean water accessibility. Our partners with Water for Empowerment are working towards bringing clean water and hygienic education to women in the developing world, and tapped two like-minded individuals to speak on the subject in front of a large crowd gathered in the Community Room.

State Representative and Democratic Candidate for Lt. Governor, Christina Hale, has spent a good portion of her career in politics fighting for women’s rights. She talked about the widespread effects of water poverty, and emphasized the value of a proper education, especially for women in the developing world. The main speaker, Wateraid’s Vincent Casey, took over the discussion to detail what happens on the ground in water impoverished areas and how his group is combatting those obstacles. It’s a multi-faceted effort focused on the delivery of technology to cultivate clean water and the educational resources to achieve and maintain a healthy lifestyle long after Wateraid has left.

Following the presentation, the building itself took center stage.  Friends, family, and colleagues passed through the halls on guided tours and impromptu jaunts; beverages and finger foods in hand as they heard the stories of the 13 Hoosier artists whose work dots the walls of the newly refurbished structure. The Community Room lived up to its name, becoming the epicenter of the celebration and serving as a space for people from all walks of life to gather in friendship, enjoy a tasty snack, and take in a slideshow of the building’s construction from start to finish. It was a night to remember, a night to cherish, and truly one that embodies the heart and soul of EnviroForensics.

ERD Delivering Effective Remediation to Indiana Drycleaner Site

ERD injectionsEnviroForensics is excited to report yet another Enhanced Reductive Dechlorination (ERD) success story. Our staff has been employing this technique for more than a decade at sites across the state and the Midwest, and it has, once again, delivered the desired effect to an impacted drycleaning property in Lafayette, Indiana.

Contamination consisting of the chlorinated solvent, PCE, was discovered in the subsurface at the Vogue Cleaners property, in an interbedded sand and clay formation. Per the Remedial Work Plan approved by the Indiana Department of Environmental Management (IDEM), we conducted an excavation on the side of the building, digging as deep as 21-feet below ground level to remove impacted soil.

In order to address groundwater impacts, we used an ERD application augmented with zero-valent iron (ZVI – an in-situ chemical reduction [ISCR] agent) to address those problem areas.  Naturally occurring bacteria called dehalococcoides (DHC) were present in the groundwater onsite and in the area of the property. As we’ve explained in past blogs, these microorganisms naturally break down chlorinated solvents by cleaving off chlorine molecules and replacing them with hydrogen particles. In order to maximize the use of these microorganisms, we injected a substrate called Lecithin mixed with ZVI ®, developed by Peroxychem, as the carbon source. Additionally, a substrate called Provect IR (produced by Provectus), which also had ZVI as an ISCR agent, was used in a different part of the site because it was determined to be more effective for the subsurface conditions found in that area.

The addition of the substrates immediately began the reduction of the PCE concentrations followed by sustained contaminant destruction over time.  The first round of ERD injections proved to be very successful. PCE concentrations, which in some spots were as high as 4,000 micrograms per liter, were knocked down to less than laboratory detection limits. These results show the typical success of ERD technologies when implemented by experienced professionals.  The remediation at the site has progressed quickly and effectively, and closure procedures are now being discussed with IDEM.  With this effective and efficient remediation we anticipate our client will receive a “covenant not to sue” from the State of Indiana shortly after site closure.

EnviroForensics Attending MWDLA Annual Convention This Weekend

It’s been a whirlwind couple of days at EnviroForensics. In the midst of the major move from our current headquarters to our new one, we’re also getting ready for one of the biggest weekends of the year, the annual Midwest Drycleaning and Laundry Association Convention!!

Over the next two days, dozens omidwestdrycleaningf drycleaners from Indiana, Kentucky and Ohio will converge on the Belterra Casino Resort and Spa in Florence, Indiana, to talk about new technologies and emerging challenges in the industry. But, of course it won’t just be strictly for business.

We’re excited to meet up with our partners and friends in the industry who have played a major role in our 20 year existence. Environmental consulting is very much, at its core, a people business. We’re brought in to clean up contamination that can threaten human health, but we’re also there to provide a safety net to the business owner, who likely never knew of the potential for pollution.

Some of these drycleaners have been our clients, but we also consider them our friends. This weekend we’ll be hitting the golf course with them, catching up over a few drinks at happy hour, and talking shop while dining on some delicious food.  We take pride in our customer service, and it’s events like these that give us a better understanding of the drycleaner experience and help us cultivate a more personal connection with our clients. If you’re heading down to Florence today, we’ll see you there!

 

EnviroForensics Takes on Multi-Faceted Cleanup at Industrial Facility with Complicated History

EnviroForensics provides our clients with strategic solutions to complex, multi-faceted problems.  Our staff works diligently within reasonable timeframes based upon our clients’ goals; striving to avoid the bureaucratic and institutional slow-downs that very commonly plague environmental cleanups.  The owner of a now defunct manufacturing facility and property recently contacted EnviroForensics to get a cleanup of multiple contaminants started after efforts by prior teams had been stalled for over a decade.  Soil and groundwater had been contaminated by chlorinated solvents and polychlorinated biphenyls (PCBs), and the majority of the building’s interior was coated with PCB laden dust and oil.  Quick negotiations with the regulators, and our team’s specialized knowledge and experience, allowed EnviroForensics to expedite a work plan and respond quickly to the owner’s requests.

PCBs are highly toxic and do not break down easily, so the EnviroForensics staff completed a detailed assessment of the building to determine the best options for managing materials that were exposed to PCBs during historical site operations.  EnviroForensics is address the contaminated building materials in accordance with the complicated and highly prescriptive Toxic Substance Control Act (TSCA).  The owner wants to make the property a productive facility within the city again, so potential exposure to contaminants for new site workers will have to be eliminated completely.  EnviroForensics efforts at the site can help make this desire a reality.

Outside of the building, EnviroForensics continues to evaluate subsurface conditions.  Monitoring wells that were previously installed at the property had not been sampled in years.  Due to this time of inactivity, the monitoring wells needed to be reconditioned by surging the well to loosen the fine particles that accumulated in the wells’ annular space, and then purging the sediment laden water.  This “surge and purge” method restored the monitoring wells’ production rate and reliability.  The entire network also needed to be resurveyed to accurately assess contaminant migration.

With a better handle of these complex issues, the EnviroForensics team plans to finalize the investigation of the site contamination, and prepare the Remediation Work Plan that the regulators have been requesting for years.

EnviroForensics Volunteers Put Muncie Minds at Ease About Lead

EnviroForensics said “yes” to a request for volunteers from the Hoosier Environmental Council.

Their assignment; find traces of lead poisoning in the ground at Muncie parks, playgrounds and community gardens.

Vick Webb, our corporate health and safety manager, and Nick Hill, senior project manager, spent a day in Muncie working alongside the HEC ‘s environmental health and water policy director Dr. Indra Frank (a frequent collaborator) and a Muncie team headed by Jenni Marsh, president and CEO of the United Way of Muncie and Delaware County.

Marsh says the effort was spurred by worries about detrimental effects of high levels of lead in the blood of children; levels that may harm brain development in pre-kindergarten children, during the most important time of brain development.

Marsh says. “We discovered: In 2014, 7% of the children tested in Delaware County had elevated BLLs. The national average of children with elevated BLL of 5 micrograms per deciliter is 2.6%. Our community’s average was more than twice that amount.”

The team fanned out to five Muncie parks and playgrounds, visiting every zip code in Delaware County’s Center Township. Using a hand auger and hand trowel, Vick and Nick extracted samples from the ground at three different locations in each park. The samples ranged from 2 inches to 8 inches deep. They were added to the team’s total and evaluated by HEC consultant Mike Ketterer of the Metropolitan State University of Denver’s chemistry department.

Ketterer received 54 soil samples from 18 specific sites. He carefully sub-sampled, oven-dried, ground and dissolved with acids. The lead was measured by flame atomic absorption spectrometry.

Ketterer says, “The majority of soil samples tested low for lead content. We did not find levels detrimental to public health.”

More testing lies ahead, but these preliminary results were “very good news,” says Dr. Frank of the HEC.

“Given the soil contamination that has been seen in other cities with similar industries, it was a tremendous relief to find only a limited number of samples with elevated lead, and those elevations were still within the EPA’s recommended limit for a playground of 400 parts per million.”

Dr. Frank adds, “For people in the center of Muncie and southern neighborhoods, I would recommend testing soil in vegetable gardens, since a few samples exceeded the limit for gardening of 200 ppm.”

The United Way’s Marsh says, “I must admit I am very surprised at how low the lead levels were. I thought we would see significantly higher parts-per-million because of their proximity to industry and lead contaminators.”

Marsh says the local committee — comprised of the United Way, City of Muncie, Ready by 5 and the Muncie Action Plan will discuss the next steps for reducing lead levels in Muncie.

And, she thanks everyone who volunteered their time and efforts. Specifically, she told Vick and Nick, “What a cool company you work for—that allows that kind of service—and what cool people you all are for taking EnviroForensics up on this opportunity!”

Marsh adds, “Each of you have worked on behalf of Delaware County’s children.”

 

EnviroForensics Develops Cost-Effective Remediation Plan for Former Dry Cleaner Client

EnviroForensics is at work remediating Crest Cleaners, a former dry cleaner in Mooresville, Indiana. Located within a mixed-use commercial and residential area, the Site is now undergoing cleanup due to historical dry cleaning activities that resulted in soil impacts onsite and groundwater impact that has migrated under buildings in the residential area.

EnviroForensics has completed excavation and removal of heavily impacted soils. Our team of environmental experts has utilized enhanced reductive dechlorination (ERD) along with in-situ chemical reduction (ISCR) to address contamination on the property. These techniques have been carefully chosen as the most cost-effective options to clean up the Site’s contamination. ISCR immediately eliminates groundwater impact, and over a two or three year time period, ERD utilizes naturally-occurring microbes to break down contaminants. Injections have been done at over 92 different locations. The goal is that after three years of injection and monitoring, the Site will be eligible for regulatory closure.

While ERD and ISCR are effective methods of reducing contamination on a property, methane is a by-product of these processes and can accumulate in nearby buildings. However, EnviroForensics is at the forefront of the industry in studying and addressing this issue. Recently, our Vapor Intrusion team presented a study entitled “The Production and Management of Methane in Soil Gas during Remediation at Drycleaner Sites” at the annual Association for Environmental Health and Sciences (AEHS) Foundation’s Conference on Soil, Water, Energy and Air. The study has also been approved for presentation at the Tenth International Battelle Conference on Remediation of Chlorinated and Recalcitrant Compounds, which will be held May 23-26 in Palm Springs, California.

At EnviroForensics, we work to ensure that contamination at your site of business is cleaned up in the most cost-effective and accurate way possible. Not only are our environmental professionals some of the best in the industry; we also have a team of insurance archeologists who are skilled in locating and utilizing historical insurance policies to help fund the costs of environmental investigation and remediation—meaning our clients pay little to nothing out-of-pocket.

Dealing with contamination on your property doesn’t have to be a burdensome and costly experience. Let EnviroForensics’ expert scientists and engineers develop the best remediation strategy for your unique situation.
