The debris left in the wake of Hurricanes Irma and Maria created a swell in the U.S. Virgin Islands’ (USVI) waste stream.
Remnants of buildings and uprooted trees cluttered the roadways, disrupting the lives of some 100,000 residents.
Many abandoned their vehicles and homes. The damages were irreversible.
In total, 72 miles of refuse needed to be disposed of — a logistical nightmare for a territory with finite resources.
“We’re running into the problem of space,” said Alice Krall, communications manager for the Virgin Islands Waste Management Authority (VIWMA). “The problem is trash being generated at amazing speed. We move it and it springs right back up.”
As dumps overflowed with mountains of debris, federal and local agencies scrambled to find neighboring countries with open capacity.
The longer the task force took to transfer refuse, the more hazardous stationary piles became.
It was the recipe for a severe environmental and public health crisis.
Changing the tide
Tropical storms weren’t the first to highlight the waste management system’s shortcomings.
Although the VIWMA’s working relationship with the EPA is improving, the underdeveloped Anguilla and Bovoni sites have been unsatisfactory for years. This is mainly because landfill surfaces are routinely left exposed, resulting in:
- Long spells of fire
- Littering scavengers
- Pervasive foul odors
- Other wind-borne materials
In recent years, however, the director of the VIWMA clamped down on the non-compliant dumps. The waste management team began sorting refuse, separating metals and instituting tipping fees. Compost and recycling programs are underway, too.
The director also saw a need for alternative daily cover. After consulting a group of engineers to adopt better practices and control environmental/public hazards, they recommended Atmos Cover ADC — a foam application that contains and protects residents from the dumps’ contents.
Slashing monthly soil expenditure by 83%
The logistics of importing good soil (compounded by scarcity) make it an expensive commodity.
Soil used in daily cover comes from pits outside of the islands. How well the soil controls fires, malodors and scavengers largely depends on its properties. These vary and aren’t always surefire.
The cost of securing high-quality soil falls anywhere between $150,000 and $200,000 a month.
Realizing this expense couldn’t be sustained, the director requested a consultation with Atmos to decrease reliance on traditional soil cover and loosen budget constraints.
Within a week, an Atmos technician was in the Virgin Islands to conduct a pre-site assessment. A custom-tailored solution that aligned with the VIWMA’s budget and goals followed.
Today, a Morooka-based Pneumatic Foam Unit (PFU) 2500 applies a layer of water-based foam at the Anguilla and Bovoni dumpsites.
The process takes one operator half an hour and, since 6 inches of daily soil cover is no longer needed, makes better use of the space. Of course, there were other challenges: The Caribbean environment poses year-round threats to landfill operations.
Taming landfill fires and unwelcome visitors
When pockets of methane meet rich oxygen concentrations under the Caribbean sun, underground fires occur. If untreated, parts of the landfill could cave in.
A subsurface cavity may be lethal. Landslides could shift heavy mounds of trash over the perimeter and crush passersby.
Personnel needs to know what lies underneath at all times to ensure safety.
The scrap metal sections contain another hazard. Fires originating from improperly disposed of cars — still containing batteries and flammable fuels — can take weeks to extinguish.
The director made controlling these spells of fire a priority and wrote Atmos’ foam solution into their fire plan. While the solution doesn’t contain every chemical found in common extinguishers — it certainly can suppress smoke emanating from hot spots.
It’s the first step in smothering fires, ultimately stopping toxic gasses from entering the public sphere.
The bird problem at St. Croix’s main airport
Hundreds of seabirds routinely swept into the dumps and scattered their meals abroad — dropping refuse into residential and municipal areas below.
Homes and businesses were covered in trash. The dumps already had a weak reputation among residents and not being able to control the scavengers only made things worse.
The larger problem? Aircraft safety.
The Anguilla landfill is situated beside a major airport runway. Too many birds in the air cause flight delays and, in severe cases, shutdowns.
The VIWMA expressed these concerns. Atmos’ field-proven alternative daily cover delivered.
The foam mixture naturally repels water, creating a 24-hour seal over landfill surfaces. It neutralizes and locks-in odors, redirecting all kinds of animals in the process.
But designing the VIWMA’s application required a unique detail. The on-site, chemical storage tank had to resist the force of a hurricane.
Securing alternative daily cover in tricky environments
One of the benefits of working with Atmos is receiving all application equipment at no charge (customers only purchase foam supplies as needed).
Some equipment, however, needs to be built from scratch to meet site requirements.
For the VIWMA, that meant repurposing a cargo container into a hurricane-proof Bulk Storage & Dilution System (BSD-7000) and bolting it down to concrete to withstand strong winds.
The custom-built storage unit would also serve as a stockroom with parts and tools to service the vehicle applicator.
Next, Atmos technicians trained the VIWMA on how to use all application equipment.
Other environmental solutions companies might see a disadvantage in partnering with an isolated chain of islands. The geographic positioning could make the area harder to reach, making poor service easy to blame on the provider.
Atmos sees opportunity.
The next chapter
The director of the VIWMA wants to rebuild its island-wide, reputable name.
Recently, she greenlit an odor misting system around the Anguilla landfill, which aims to contain foul odors and amend the agency’s relationship with the bordering airport.
If you believe Atmos products and equipment could boost your environmental remediation plan or waste management system, let’s talk today.
What happens when two of the industry’s best join forces? Meet Atmos Technologies.

A short drive south of downtown Detroit is the Riverview Land Preserve, an approximately 400-acre solid waste landfill opened in 1968 that presently receives around 2,500 tons of trash a day.
It’s a dynamic site with private homes, public spaces and local waterways all in close proximity.
Consider its geography:
- Residential neighborhoods are immediately adjacent to parts of the property’s southern, western and northern boundaries
- An active municipal golf course borders its entire eastern boundary
- A handful of creeks and ponds are nearby, and the site is just two miles from the Detroit River
Approved daily cover material at the site included soil, wood chips and recycled tire chips. Soil had been the primary material; wood and tire chips were used if bad weather made earthwork impossible.
But unique circumstances in 2018 led site management to search for a better daily cover system. What sort of system that would be was still up in the air.
The circumstances
At the time, one cell at Riverview was actively receiving trash. Operators already knew where the next cell would be, but it was not yet approved for operations.
Here was the problem: Space was running out in the active cell. Regulatory approval for the new cell had not been granted. Not only was space in short supply, but without excavation in the new cell, the site was becoming dirt poor very quickly.
As a last resort, operators were forced to use clean fill from a borrow pit to perform daily cover. This was far from ideal because the borrow pit is located off-site, requiring added cost and transportation time. That soil also was initially earmarked for final capping of the almost-full cell and not for daily cover. They needed an alternative quickly to preserve the space available in the active cell.
As a stop-gap measure, Riverview purchased a tarp system to buy time for leaders to settle on a permanent alternative.
But Riverview also faced another challenge that landfill operators everywhere know all too well: Relying on soil daily cover is time- and labor-intensive and puts exceptional strain on heavy equipment like dozers, backhoes and dump trucks.
Atmos’ ADC foam demo sealed the deal
By 2019, the search for an alternative daily cover system had taken site operators across the country to see various options in action.
But one particular demonstration in northeast Pennsylvania stood out. The system on display there looked like it would work at Riverview. The only hurdle left was verifying with Michigan regulators that this was an approved alternative cover method. It was.
The equipment arrived at Riverview on a trial basis in March 2020 and has remained in place ever since. According to Riverview Land Preserve Operations Manager Kevin Sisk, the system’s impacts on operations were immediate and far-reaching.
By switching to the foam daily cover, Riverview Land Preserve:
- Slashed combined man and machine hours on daily cover operations to a fraction of what it had been
- Dramatically reduced daily wear and costly maintenance on its fleet of heavy equipment
- Made reductions in their labor force
- Redirected its remaining labor force to complete a wider range of other projects more quickly
A key component of working with Atmos is our unique model providing the state-of-the-art application equipment free of charge with the purchase of chemicals. This frees up funds for the site to allocate to other capital projects that may arise.
As a result of this transition, Riverview runs more efficiently, has cut costs and can conduct advanced project planning instead of merely reacting to day-to-day site needs.
Good thing, too. Another challenge was around the corner.
Odor control rounds out turnkey solution
As in many solid waste landfills, the Riverview Land Preserve contains several wells as part of its gas collection and control system.
The wells are designed to collect and flare landfill gases to eliminate unpleasant smells, but as they fail they operate less effectively.
Later on in 2020, after the foam cover system had arrived on-site, some of the gas wells at Riverview came due for replacement. As that work commenced, so did odor complaints from nearby residents.
Riverview approached our team to see if we could help.
After visiting a site where we had installed an odor neutralizing system, Riverview decided it was the right solution. Same as the foam cover system, it would be leased under a usage agreement so Riverview would not need to incur a capital expense.
The system was installed at the top of the hill with the fan blowing the mist directly over the area where the well work was underway.
It did its job: Atmos’ odor neutralizers helped eliminate the malodors at their source. Odor complaints from Riverview’s neighbors fell off drastically. The site also utilized Atmos’ odor neutralizers to stem odors emanating from the landfill working face. The linear misting system was set up on the perimeter of the working face to prevent working face odors as garbage was deposited into the cell.
Riverview is optimistic that Wayne County and the Michigan Department of Environment, Great Lakes, and Energy will approve a pending application for expansion, partly on the strength of the site’s effective daily cover and odor control regimen.
A service-always mindset
Riverview Land Preserve became an Atmos customer because they saw proof that its alternate daily cover worked in the field. Then, with the installation of the multiple odor neutralization systems, a partnership was born.
The service is there. It’s a rarity in this business.
