We are excited to welcome back Tara Harvey to the blog today. Tara is a Hydrogeologist with the Lake Simcoe Region Conservation Authority. Previously she told us all about why she was always standing in fields. For more about Tara, see the end of this post.
Field work is fantastic! It’s a great opportunity to get out of the office, stretch your legs, and collect some data. And even when you are doing the same type of field work over and over and over again, Mother Nature can make things interesting when you least expect it.
As a hydrogeologist (someone who studies geology and groundwater), the field work I tend to participate in is rather repetitive and might not be considered super exciting. I don’t get to go searching for animals in the wild, I don’t get to use fancy equipment, and I don’t typically get to travel to far off lands. What I do get to do is go out to construction sites, or other places where we are interested in monitoring groundwater quality or quantity, and either take a small sample or use a measuring tape to determine the water depth. Very exciting, right? Regardless, I do really love field work and have some pretty interesting stories, most of which are all thanks to good old Mother Nature.
In the summer of 2017, I was up in Northern Ontario to do some groundwater sampling. Now, you can collect groundwater samples for many reasons, but the general goal is always to see what chemicals or contaminants are in the water. This time around we were interested in monitoring the movement of chemicals from an active industrial site to make sure there was no negative impact to the natural environment. But what should have been a very easy, mundane, and predictable field excursion turned out to be anything but.
Of course, Mother Nature isn’t the only unknown force that can upset a tightly designed field schedule. Nope, you also have to account for the unpredictable behaviour of both the Canadian postal system and your teammates’ memories. Unfortunately for us, on this particular field adventure all three things went a little awry. Firstly, one of our team members forgot to ship some of the equipment we needed for the field work to the site. The delay could have been a problem – but ended up not mattering, since even the equipment that was shipped on time showed up several days late courtesy of Canada post.
But the most interesting surprise was this….
In case you can’t tell from the photo, that is a completely burned forest! Yes, just the day before we arrived to get our groundwater samples, a forest fire burned through the area, destroying all the vegetation in its path.
The fire had happened so recently that the Ministry of Natural Resources and Forestry were still conducting their investigation to determine whether it had been caused by natural or human forces. Either way, the fire was actually very confined and caused minimal damage beyond a very small section of burned forest. Even the trees weren’t badly affected, and should continue to grow in the future.
Regardless of the limited damage, it was definitely an unexpected sight that we walked into on that first day. Immediately, we wondered what the fire meant for our groundwater wells, which are 2-inch plastic tubes that stick out of the ground and might have melted. Did they survive? Would we even be able to do any of our field work at all? Luckily, we soon found out that although the fire burned everything that was alive, all of the wells on site were perfectly fine since they had protective metal casings over top of them! Thankfully. If the plastic wells themselves had been exposed, this might have been a different story.
Although the forest fire destruction was a surprise, it actually made our work easier in the end, since we didn’t have to fight against the vegetation to go find our wells in the ‘jungle’. And it definitely made for some interesting, if not beautiful, photos.
The lesson I took away from this field excursion, and the lesson I always take away from field work, is to be prepared! You never know what is going to go wrong or what is going to surprise you, especially Mother Nature.
Tara Harvey works as a Hydrogeologist with the Lake Simcoe Region Conservation Authority and has previous experience in research and consulting with the G360 Institute for Groundwater Research and Cole Engineering. Tara specializes in Quaternary geology, aka glacial geology, but now spends much of her time working on Source Water Protection in Ontario to make sure our drinking water sources (lakes, rivers, and groundwater) stay protected.
