Regina Donohoe is an OSPR staff toxicologist working in the Resource Restoration Program. As an ecotoxicologist, she combines the methods of ecology and toxicology to evaluate the effects of pollutants on fish, wildlife and their habitats.

For the past 17 years, Regina has been involved in the remediation of hazardous waste sites, petroleum production facilities and military bases to ensure that chemical contamination is cleaned up to levels that are protective of our natural resources. Regina also provides ecotoxicology support for spill response and assesses the injuries resulting from spills as part of the natural resource damage assessment team.

Regina received a Ph.D. in toxicology from Oregon State University, a M.S. in ecology from San Diego State University and a B.S. in environmental toxicology from the University of California at Davis.

Who or what inspired you to become a scientist?

One summer day when I was a bored five-year-old, my mom asked me to roam our foothills property and bring back every different kind of leaf I could find. It was a clever mom move to keep me busy all afternoon but it is my earliest memory of being fascinated with nature. However, it wasn’t until I met my high school biology teacher that I knew I wanted to be a scientist. Her classroom was a museum filled with skeletons, shells, plants and aquaria of fish, and that class set me on the path to major in science in college. Later, my graduate school advisors shared their passion for science and kept me going.

What got you interested in working with fish and wildlife?

While trying to decide on an undergraduate major, I took an introduction to environmental toxicology class. The professor told the grisly story of the dancing cats of Minimata Bay, Japan during the 1950s. After mercury-laden wastewater was released into the Bay, the fish accumulated it and when the cats ate the fish, they began to walk erratically (or “dance”) because the mercury poisoned their nervous system. It was an “aha” moment. The fact that a single chemical could disrupt an entire ecosystem intrigued and saddened me at the same time, inspiring me to declare environmental toxicology as my major and the focus of my career.

What brought you to CDFW? What inspires you to stay?

It was 1982 when I took a year-long Student Assistant job at the Pesticide Investigation Unit Laboratory of the then-California Department of Fish and Game. The job duties included “creamer patrol,” picking up dead carp from agricultural drains in the Sacramento Valley for pesticide analysis. On a 100° F day, the fish decayed so quickly that when they were scooped up in the net they often exploded into a creamy mess. Another aspect of the job was to conduct bioassays with fish to determine what levels of pesticides in the water were safe. I left the position to study the effects of sewage discharges on the algal populations of Tijuana estuary, meeting my husband while knee-deep in mud. After that, I researched how chemicals could act like hormones, with environmental estrogens altering reproduction in fish. This led to an ecotoxicologist job at the California Environmental Protection Agency. A friend recommended I apply for a job at OSPR and 17 years later, I returned to where I had started.

What is a typical day like for you at work?

My work moves in a couple of different gears. On the slower gear, a ten-year timeframe, I work on remediation of military bases and hazardous waste sites. For each site, the nature and extent of chemical contamination is characterized, the method and level of cleanup is decided, cleanup occurs and then there is follow-up monitoring. For example, we have removed lead bullets from sand dune firing ranges, metal plating waste from salt marshes and crude oil from grasslands. Throughout the multi-year process for each site, I make many visits, read reports, attend meetings and provide comments related to ecotoxicology.

When spills happen, everything shifts into high gear. I pull together information about the spill, plan and conduct studies and assist wherever help is needed. After the spill response ends, the natural resource damage assessment process continues but at a less frenetic pace. I analyze data, prepare presentations and write up results.

In between, I am involved in training and planning, teaching classes on the effects of oil on ecosystems and reviewing literature to be better prepared for the next spill.

Over the course of your career, was there a discovery or an incident that surprised you?

When we were called to respond to the oil spill in Santa Barbara in 2015, we had to plan for fish sampling one day and carry it out the following day. Usually, it might take a couple of weeks to organize such a sampling event. But people from multiple agencies volunteered their gear and help, others quickly purchased needed supplies, experts flew in to collect tissue samples and folks drove many miles to be there on short notice. The sampling day began early, including gearing up in bulky protective clothing to fish on the beach, and ended with a late night of data intake. Everyone brought a positive attitude and worked hard to get the samples we needed to support the natural resource damage assessment. We achieved a near-impossible task because everyone gave it their all. The power of people working together truly surprised and amazed me.

What do you enjoy most about working in ecotoxicology?

California has incredibly diverse ecosystems – deserts, grasslands, chaparral, forests, rivers, wetlands, estuaries and marine habitat. Spills happen all over California, providing me opportunities to investigate impacts to many plant and animal species in a wide variety of habitats and spill scenarios. For example, I’ve been asked: How does diesel affect an old growth redwood tree? What levels of metals are of concern to California Tiger Salamanders? Is brine harmful to ephemeral streams? How does crude oil impact kelp forests? These questions make me scratch my head and think, and learn new things every day. That, to me, is the best thing about being a scientist.

If you had free reign and unlimited funding, what scientific project would you most like to do?

When scientists began to evaluate how oil spills affected ecosystems in the 1970s, they did some interesting laboratory and field studies, but they were limited by the analytical chemistry and assessment methods available at the time. In many cases, oil concentrations in water or tissues were not measured or were simply quantified as total hydrocarbons. Today, we know that oil is a mixture of hundreds to thousands of chemicals that we can quantify at very low levels in the environment. We also have new biochemical and genetic tools that can detect subtle changes in animals in response to oil exposure. It would be great to repeat many of those earlier studies using our current technologies to further our understanding of how oil affects ecosystems, improving our ability to respond to spills and restore habitats following spills.

Do you have any advice for people considering careers in science or natural resources?

Follow that innate scent trail. What makes work seem like play? What keeps you going when you lose the trail? What rewards you at the end of the day? If you have a passion for science or the natural resources, make it your career and be sure to stop and smell all those interesting scents along the way.

Hailey Marie Harrell is an Office of Spill Prevention and Response (OSPR) environmental scientist working as part of the Northern Field Response Team. She graduated from the University of California, Davis, in 2013, with a double major in Plant Biology and English.

Hailey was initially hired as a scientific aid for CDFW’s Habitat Conservation Planning Branch’s Native Plant Program. There, she had the opportunity to do field work with skilled botanists on some of California’s most sensitive plants, conduct census surveys and issue California Endangered Species Act scientific collection permits. She promoted to a permanent role with OSPR in 2016, and has been immersed in the world of oil spill prevention and response ever since.

A relative newcomer to CDFW in terms of job tenure, Hailey has a very fresh perspective on working as an OSPR environmental scientist.

Who or what inspired your love of natural resources?

I’ve spent countless hours in the woods and along waters of this state and I have observed many wonderful and fascinating things within them. I was raised by avid hunters and fishermen who instilled in me an admiration of our truly beautiful natural resources. They hammered home the importance of conservation and taught me to take care to leave places as good as, if not better, than I found them.

How did you come to work for CDFW?

I chose to study plants instead of animals when I got to college because they were a form of life I knew very little about. I was encouraged by a few professors who liked my writing style to take English courses while in college because it is rare to find someone who loves science and also enjoys writing. They saw me as a bridge between technical information and the layperson.

After college, I took a job as a technical writer for a privately contracted aerospace and defense company. After several months, I had learned all the ins and outs of the position and no longer felt challenged. I spent every minute of every 40-hour workweek sitting at a desk in front of a computer screen. In the small bits of time I could manage, I took every opportunity to network with people that were already working in various natural resource agencies. Through these interactions, I got to know some great employees of CDFW who gave me advice and let me do some volunteer work to gain experience for my resume. I eventually landed a scientific aid position with CDFW’s Native Plant Program where I learned my way around the intricacies of state service as I assisted in surveying some of California’s amazing threatened and endangered plant species and issued permits for their protection.

Why did you change your focus from native plants to oil spill response?

I didn’t know if I could love a job as much as the one I had with the Native Plant Program, but knew I couldn’t stay a scientific aid forever so I applied for environmental scientist positions. The OSPR position I have now was the only one of many applications I submitted that gave me a call back. I went into my interview knowing nothing about OSPR except what I had scrambled to learn about it before the interview. I was ecstatic, but at the time had no idea how truly lucky I would be to be offered this position.

Was there a tough learning curve?

The learning curve when joining OSPR was very steep, initially. I think the most challenging aspect was figuring out all the acronyms that are used. In working with the Native Plant Program I scrambled to learn the intricacies of working for a government agency, but the language itself was straightforward because I was exposed to plant terminology throughout college. OSPR was a whole different ball game. For example, it took some time just for me to realize that they were saying “T and E” species (referring to threatened and endangered wildlife) instead of “teeny” species. I would hear the question, “Were any teeny species impacted by the spill?” and would quietly wonder why they were only concerned with little organisms.

In your new position at OSPR, what are your typical duties?

As a first responder to petroleum spills, I work with a wide variety of our state’s natural resources and travel to many beautiful places across California. I get to work closely with our game wardens, the U.S. Coast Guard, private industry and other local, state and federal government agencies. At some spills, I will be the first person on scene and will have to convey my initial findings to my team to determine what level of response we will need to resolve the issue. Sometimes I will be on my own to resolve the issue, sometimes there will be a small group of us working together and sometimes there will be a large contingency of federal, state and local agencies involved to help resolve the incident. Each incident has a unique set of obstacles that need to be overcome. I fill whatever role is necessary to help get the job done as quickly as possible.

This job is also full of surprises. Few days are the same as a first responder to petroleum spills. One minute you think you’ll be in the office all day and the next minute you’re in the car driving to the coast to walk the shorelines and look for oil, or responding to a sunken vessel, or getting to the scene of a truck crash, etc. Weird reports sometimes come in that challenge your knowledge and your strategies for managing problems. It is hard to get bored, and that is one of the many things I love about it.

What has been the most exciting or enjoyable aspect of working at OSPR for you so far?

I think that the most exciting part of the job has to be emergency response. When you go on call you never really know what kind of spills you are going to get. When you get a report of a spill that warrants a response you generally know where you need to go, but there’s almost always some ambiguity regarding what you are going to find. I love working in a position where there’s so much variety.

The networking, training and interagency collaboration are equally enjoyable aspects of the job. For example, one of my first oil spill drills played out a scenario at an oil refinery in San Pablo Bay. It was a large drill with key representatives from the refinery, government agencies, county hazmat, etc. No more than a month later, there was a response to that very same refinery and almost all of those key players I met at the drill were in the command post during a real event. It felt like déjà vu being there and seeing everyone again. It helped put into perspective just how important it is to practice with drills and meet the key players that will be involved during real spills. It builds trust and understanding between those parties involved and helps to demonstrate that we are all working towards a common goal.

You’re still early in your career. Where do you think you will be, professionally speaking, in five years, or 20 years?

I can really see myself sticking with OSPR for the long hall through to retirement. From discussions with friends and family, this really is a unique and amazing position I am in that is unlike any they have heard of before. I need variety to keep myself content and OSPR certainly has that.

Any advice for people considering careers in science or natural resources?

Having a job where I could contribute to prolonging our natural resources and get out in the outdoors to enjoy them as much as possible has been a dream I did not know I would achieve, but that was my goal and I fought for it. You may have to scrape by and do things that you don’t want to for a while (maybe even a long while), but if you have enthusiasm, determination and a true love of conserving our natural resources, keep working towards your goals. Talk to people, volunteer your time and keep climbing the ladder. Eventually, if you remain persistent, you will find yourself somewhere you never thought you’d be, with a job that you can’t imagine being without.
