NH LoVoTECS Snapshot Summary

LoVoTECS expands into coastal Maine to investigate beach & shellfish flat closures

Last year, Plymouth State University was the partial recipient of a grant from the National Science Foundation to integrate research across state lines.  As a result, LoVoTECS expanded its network into coastal Maine in order to investigate water quality related to closure of beaches and shellfish flats (http://www.newenglandsustainabilityconsortium.org/safe-beaches-shellfish).  We are excited to welcome our new partners, who include: the Hancock & Cumberland County Soil and Water Conservation Districts, City of Ellsworth, Kennebec Esutary Land Trust, UMaine Cooperative Extension/Tanglewood 4-H Camp, Coastal Studies for Girls and the Town of Hampton!

Below is a list of the new sites installed this field season: 

1.   Mousam River, Kennebunk, ME  (MSM)

2.  Card Brook, Ellsworth, ME (CAR)

3.  McFarland Brook, Trenton, ME (MCF)

4.  Flood Steam, Surry, ME (FLD)

5.  Peters Brook, E. Blue Hill, ME (PET)

6. Long Creek, Portland, ME (2 sites: S18, S19)

7. Concord Gully, Freeport, ME (CGB)

8.  Merrymeeting Bay/Chopps Point, Woolwich , ME (CHP)

9.  Ducktrap River, Lincolnville, ME (DUK)

10. Taylor River, Hampton, NH (TAY)

Our data will help provide information for other interests besides beach and shellfish closures- Check out the restoration project at Long Creek site: http://www.restorelongcreek.org/

New Graduate Student

Hi everyone!

Baker River, Plymouth NH
Photograph by Lisa Scott

My name is Dan Demers and I’m an Environmental Science and Policy graduate assistant at Plymouth State University working with data from the LoVoTECS Network.

Prior to joining the program, I graduated from Westfield State University in 2011 with a Bachelor’s of Science in Environmental Science and worked in a semi-volatile organic compound laboratory in Western Massachusetts.

Currently, I am looking at the characteristics of specific electrical conductance (SpEC) at certain LoVoTECS sensor sites. SpEC is electrical conductance (which is measured by the black, HOBO U24 sensors) after it has been corrected for the temperature of the water. It is a measure of how well water conducts electricity, increasing with the addition of dissolved solids. Pure, deionized water does not conduct electricity at all, so this measurement can help us learn about the presence and movement of ions within our streams.

Here in New Hampshire, road salt is one of the key factors that increases the SpEC of water, but it isn’t the only material that does this, as you can see from the 2013 and 2014 snapshot results (link coming soon). If the SpEC conductance of water becomes too high, it can affect organisms living in the stream.

Usually when a storm occurs, the SpEC in a stream dilutes with the addition of the new rain-water. However, during the beginning of some storm events, at some sensor sites, the SpEC will briefly increase before diluting. This increase, caused by a flushing of solutes into the stream (known as first flush), can be quite large in some instances, even reaching levels which can have an acute effect on lotic organisms.

I’m specifically looking at sensor sites in the network that exhibit this first flush behavior in order to analyze how the events are affected by seasonality, storm intensity, and the environmental conditions since a previous storm. Essentially this means that I’m studying how time affects the ways in which solute flushing events occur and behave.

Going forward, I hope to be able to accurately predict the presence, duration, and magnitude of solute flushing at certain sites. This knowledge will increase understanding of how water and solutes are transported within our local environment and will be able to indicate which environmental conditions might lead to SpEC-related problems for some lotic organisms’ well-being.

Tracing Urban Stormwater

Our partners at Keene High School, Keene State College, and technician Errin have been monitoring Beaver Brook above and below the city of Keene (sites BBU and BBD, respectively). They also have sensors in an urban storm drain (site BWS) that contributes to Beaver Creek between BBU and BBD. We have enjoyed viewing the data, so thought that we would share.



Below is a time series from October 2013 showing water stage and specific electrical conductance at the three sites, highlighting three storms. The first is on Oct 4, which barely impacts the upstream site, has a clear signal in the storm drain, and that signal is also strong downstream of town. The rapid increase in stage and decrease in specific electrical conductance (SpEC) are typical storm responses within the LoVoTECS network. Groundwater is generally saltier than rain - thus the higher SpEC at low flows - and so direct runoff of rain dilutes a stream. But, the upstream site does not show a substantial stage or SpEC change after the Oct 4 event, which was about 0.5 inches of rain according to area CoCoRaHS observers. The two next waves of rain on Oct 6 and 8, were generally smaller than the Oct 4 amount, but the storm drain reacts strongly and so does the BBD downstream site. The upstream site shows some response to the Oct 6 and 8 rain, but much less than the other sites.

This clear impact of urban drainage on direct runoff to streams is novel. Because urban areas are so small relative to other land covers in a watershed, it is difficult to detect the hydrologic impact of urbanization in watersheds (see Hollis' critical view and O'Driscoll's recent review). Our partners and their sensors are seeing the impact.

102 sites were sampled on 9/3/14!!! Check out your site's data and compare to July!

Gearing Up For 2014 Field Season

We aren't the only ones emerging this spring. Contoocook River, Henniker, NH.

2014 LoVoTECS news & dates to put on your calendar:

• Spring Interval Change: taking place this month, May 9th-May 18th. Resources for the procedure can be found at: https://www.plymouth.edu/center-for-the-environment/files/2014/05/spring-inteval-change-instructions.pdf
• Ashley Hyde will be defending her MS thesis Friday, May 23rd at 11:00, featuring LoVoTECS data. It will be held in Boyd Lecture Hall (001) at Plymouth State University. 
• U24, conductivity meter battery issues (black sensor): we are approaching the battery life of the conductivity meter (black sensor), we've had ~2 dozen units already fail. Please note that if you try to offload your conductivity meter and after realigning and cleaning the optics you are still getting a red "fail" LED light remove the sensor from the shuttle and look into the communication end of the sensor. 

When the sensor is working properly there is a red light that blinks every few seconds, if you do not see this blinking light it is likely that the battery failed during winter deployment. If this happens, please pull the sensor from your site and send an email to report the problem. The battery life on the silver, water level logger appears to be better, as we haven't had any reports of battery failures on those units.

• Winter sensor shifting or sensor loss: We expect a higher number of sensor shifting or loss from the heavy ice coverage this past winter and high flows this spring. If you noticed that your sensor has shifted or is gone completely, please contact us as soon as it's noticed via email or phone to report the problem. 
• The grand total of donated time by LoVoTECS host: From February 2012-today, we've estimated that LoVoTECS hosts have donated over 2,400 hours and 8,300 miles amounting to more than $58,000. Truly an invaluable contribution and LoVoTECS would not be possible without the commitment and dedication of our hosts!
• 2014 Summer Snapshot: We are in the process of organizing another 2014 Summer Snapshot event, the dates have not yet been picked but it is likely that we will be sampling June, July and August or July, August and September.
