The Nature Lover in the Factory: Meet Environmental Scientist Lexi Pratt

Lexi Pratt, Ph.D., Environmental Scientist at Shive-Hattery, spends her time in two seemingly opposite places: manufacturing facilities and the great outdoors.

Lexi grew up in the woods and the water, outside of Lake Placid, NY.

Her childhood in the park – the largest protected land area in the continental U.S. –  instilled in her a deep appreciation for how environmental health and human health are connected.

“The Adirondack Park was created as a way to protect the watershed for New York City. It’s a framework for people living with the land. It’s a unique place where people and nature intersect.”

Today as an environmental scientist, she navigates the complex systems inside factories, helping companies understand and improve their impact on environmental and worker health. In her free time, she’s visiting all 63 national parks. Those worlds may seem miles apart, but not for Pratt. At work or on the trail, she knows that what happens upstream matters.

Lexi’s “Why”: An Upstream Approach

Pratt’s passion is industrial clients: Manufacturers, food processers, and more. Since they’re usually huge operations, they have an outsized opportunity to improve or degrade health.

It all starts as early in the process as possible. “If you have cleaner air and cleaner water, instances of disease – asthma, cancer, all of them – go down,” Pratt says.

“You look at what’s causing risk in the first place. If you catch those factors early—whether it’s emissions, permitting gaps, or material handling, you prevent downstream problems like health issues, fines and downtime.”

For a nature-lover, isn’t working with factories like helping the bad guys? “I don’t think that industrial facilities in general want to emit pollutants. The people working in those facilities live around them,” says Pratt. “Most people we work with are trying to install control equipment to make their processes as clean as possible, trying to comply with regulations. I think people now have that broader understanding that what we do here can impact someone else.”

“I help my clients make sure no one goes home sicker than they came in, and that their facility doesn’t put their community or business at risk.”

From Adirondack Curiosity to Industrial Frontlines  

Pratt’s path was shaped by where she grew up. Raised outside Lake Placid in the heart of the Adirondack Park, she was always outside. “I was the type of kid you had to yell at to come in at night,” she said. “I was always creating my own science experiments outside, driving my parents crazy in the process.” 

By 16, she had tested out of her high school and moved on to college. One of her first projects was comparing air emissions and pollutants between biomass boilers and typical fuel boilers. This project started her love of air science and particle physics. She decided to move to Iowa City to pursue her Master of Science in Industrial Hygiene at the University of Iowa. Her thesis focused on modeling the deposition of aerosols in the respiratory tract.  

She would go on to earn a Ph.D. in occupational and environmental health. Her dissertation focused on virus and particle transmission in hospitals between infected patients and healthcare professionals. She used her knowledge of aerosol science and ventilation design to create a unique “negative pressure face shield” to protect healthcare workers during the COVID-19 pandemic.  

After her doctorate., Pratt spent three years at the U.S. Department of Veterans Affairs as a postdoctoral scholar where she analyzed the health effects associated with soldiers’ exposure to burn pits and other occupational hazards. She now applies her expertise in indoor and outdoor air quality to the industrial world, where every decision can affect workers, communities, and compliance standing. 

What is an Environmental Health and Safety Specialist?

An Environmental Health and Safety (EHS) Specialist works to protect workers, communities, and operations from environmental and safety risks. That includes monitoring regulatory compliance, conducting industrial hygiene assessments, leading incident investigations, delivering training, and supporting audits. For many facilities, having dedicated EHS expertise, whether in-house or through a consulting partner, is what keeps operations running and people safe.

Today: A Coach for Industrial Air Quality Compliance  

Today, Pratt focuses on air quality compliance—from permitting boilers and cooling towers to helping major industrial players calculate emissions and meet evolving state and federal standards. A large part of compliance is simply staying up to date.  

“Regulations are always changing,” Pratt explains. “Understanding what applies to your site is hard. Add growth, new equipment, or construction to the mix, and it gets even more complex.” 

But complexity is where Pratt thrives. “I enjoy the problem-solving aspect of it. They’re all such unique facilities,” she explains.  

Common pitfalls she sees most often: 

• Permits initiated too late, triggering project delays 

• Confusing emissions calculations and reporting requirements, leading to neglected or incorrect documentation  

• Turnover in compliance roles, resulting in missed filings and broken transfer of knowledge  

Pratt’s Advice for Manufacturers: Start Upstream 

Pratt supports clients not only in ongoing compliance, but at the beginning of projects, where the impacts can be huge:  

• Facility expansion or new construction 

• Renovations 

• New product lines 

• New equipment  

If you’re a plant manager or environmental health and safety leader working on a project like this, don’t wait to bring environmental strategy into the conversation. 

“Environmental services need to be baked in before a new line starts running or the facility expands,” Pratt says. “It’s a lot easier to do our job when we’re involved at the beginning. Waiting until the end – when you’re having to redesign systems or respond to penalties – is what creates the problems.”

Case Study

From Urgent EHS Support to Long-Term Partnership 

Sometimes the fastest path to EHS compliance isn’t a new hire. It’s the right partner. 

A large food manufacturer needed air compliance support quickly. While they searched for an in-house Environmental Health and Safety (EHS) hire, they needed experienced support in place to keep operations moving. 

Shive-Hattery stepped in with: 

• On-site presence to support maintenance, monitor compliance, and answer day-to-day questions 

• Regular reporting support and communication across engineering, production, and EHS teams 

• A flexible, indefinite delivery contract designed to adapt as needs evolved 

The manufacturer filled the in-house role and kept Shive-Hattery on as a long-term partner. Today, the team continues to monitor compliance, prepare for new projects, and work through regulatory changes together.

Inside the Job and Outside the Office

When she’s not decoding regulations, Pratt is usually outdoors. She and her husband are on a mission to visit all 63 U.S. national parks. They’re at 20 so far.

Ask her about the time a black bear wandered into her family’s Smoky Mountain cabin and made off with the their lunch and you will see the same enthusiasm that she brings to every project.
