TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 22, 2021.  This episode is a revised version of an episode from February 2013.

MUSIC – ~15 sec – instrumental

That’s part of “Chesapeake Bay Ballad,” composed for Virginia Water Radio by Torrin Hallett, a graduate student at Lamont School of Music in Denver.  It sets the stage for a series of Bay-related mystery sounds.  Have a listen for about 30 seconds, and see if you can guess what kind of animals these six creatures are, and a seasonal thing they have in common.  And here’s a hint: if you think cold, you’re warm!

SOUNDS - ~ 32 sec


If you guessed all birds, you’re right!  The sounds, in order, were the Horned Grebe, Dunlin, American Coot, Hooded Merganser, Tundra Swan, and Snow Goose.  The seasonal thing they share is that they are winter residents around Chesapeake Bay area waters.  According to Life in the Chesapeake Bay, by Alice and Robert Lippson, some 22 bird species are commonly found in winter around the Bay but are uncommon or not present at all during summer.  And a similar number of Bay-area bird species are just the opposite—rare in winter but common in warmer months.  So as spring arrives, the first of two yearly feathered comings-and-goings will start to fill the skies over Virginia’s coastal waters.

Thanks to the Lang Elliott and NatureSound Studio for permission to use the grebe, dunlin, coot, and merganser sounds, from the Stokes Field Guide to Birds Songs; and thanks to the U.S. Fish and Wildlife Service for the Tundra Swan and Snow Goose sounds.  Thanks also to Torrin Hallett for this week’s music, and we close the final 35 seconds of “Chesapeake Bay Ballad.”

MUSIC – ~34 sec – instrumental

TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 15, 2021.

SOUND - ~7 sec – Pouring water then ice cubes

This week, we focus on drinking water and Virginia Tech research on customers’ trust of their local water supply system.  Our guest voice this week is Maddy Grupper, a recent master’s graduate from the Virginia Tech Department of Forest Resources and Environmental Conservation.  We start with a 40-second except of a talk Maddy gave on her research at the Nutshell Games, conducted by the Virginia Tech Center for Communicating Science. 

VOICE - 38 sec – Nutshell Games excerpt: “It’s 2014, you live in Toledo, OH…Thick green algae has invaded Lake Erie, your water source, and for days you can’t fill up your water from the faucet and drink. What if we could prevent this? What if we could predict when water is going to go bad the same way a weatherman predicts a tornado…  We’re developing this technology…  But successful technology isn’t just the ones that work, it’s what the public trusts, accepts, and uses.  I study what factors impact that trust.”

GUEST VOICE

Hello, I’m Maddy Grupper, speaking to you now in 2021.  As you heard in that excerpt, I study people’s trust in the quality and safety of their drinking water. The quality of lakes, reservoirs, and other sources that humans use for drinking water can be affected by climate change, infrastructure degradation, and pollutants. Researchers are looking for innovative methods to maintain drinking water quality, such as technology to forecast threats like algae blooms and metal increases. But without trust, people might not support such new technologies or other changes. That can slow the ability of utilities to stay ahead of fast-acting threats. 

The focus of my Virginia Tech master’s study was on the trust that community members have, or don’t have, in their utility.  In the fall of 2019 we surveyed over 600 customers of the water utility serving the Roanoke Valley of Virginia.  We found that 61% of the respondents mostly or completely trusted their utility to deliver safe drinking water to them.

What is the basis of such trust?  Our study found evidence supporting a framework that claims a person’s trust is based on four sources: 

1. Rational – that is, I trust you because I think you’re capable and have a good track record.

2. Affinitive – that is, I trust you because I like you, think you share my values, and have my best interests at heart.

3. Dispositional – that is, I trust you because I’m a trusting person.

And 4. Procedural – that is, I trust the system that regulates you.

Our study in the Roanoke Valley showed that as each of these factors increased, so did trust.  But we also found that high trust didn’t rely on just one or two of these factors; it needed all four.

If water managers want to increase community support through trust, they need to take all four factors into account.  Understanding these trust factors might help water managers build more resilient systems. For community members, such understanding might give them a greater sense of control and peace of mind about what they drink.

So, the next time you take a sip of water ask yourself, why do you, or don’t you, trust what you are drinking?
