Systematically monitoring and recording the water quality of Sligo Creek, and educating the public about the importance of clean water for fish and wildlife

What the Water Quality Committee is Doing Now

Volunteers needed for summer water quality testing

Sligo Creek Jackson Ave testing site

FOSC needs water quality testers for each of the 3 sites along Sligo and for 1 site on Long Branch. Volunteers record water temperature, air temperature, dissolved oxygen, pH, and turbidity, and take water samples to be analyzed for bacteria at Anacostia Riverkeeper’s lab. Do not worry if these terms are unfamiliar. All will be taught in the training! Monitoring usually takes just 15 minutes. Anyone 18+ years old (or older children under the supervision of a parent/guardian) can participate.

The data from the program helps FOSC, ARK, Montgomery Parks, and state and local agencies learn more about the chemical and biological health of Sligo and Long Branch. To volunteer, sign up for one of the two virtual training sessions, May 5 and May 20 @ 10am.

USGS in Sligo Creek – presentation to FOSC

Chuck Walker of the regional USGS MD-DE-DG Water Science Center spoke on the health and water quality of Sligo Creek. The Water Science Center has partnered with MoCo DEP to collect continuous water quality data on 7 parameters at the Maple Ave gauge. How is Sligo faring compared to other regional streams? Chuck told us about the long term trends and implications for Sligo as our area gets more densely populated. If you missed the event, check out the video on FOSC’s YouTube channel.

WQ Committee Starts 2 Road Salt Initiatives This Winter – Volunteers needed!

1) Road Salt Testing in which volunteers test Sligo waters before, during and after a snow event. We provide the simple testing kits through a partnership with the Izaak Walton League plus guidance on selecting a location to test and when to test. Check out the new FOSC Road Salt Initiatives page for more information.

2) Road Salt Reporting in the Sligo Creek Watershed. If you see an excessive salt pile in the Sligo Creek Watershed, please send an email with location, date, time and a photo to [email protected]. We will try to get the County, State or responsible party to remove excessive salt piles before they go into Sligo Creek.

How’s the Water? Webinar

Anacostia Riverkeeper (ARK) shared the results of the 2021 Summer Water Quality Testing Program in MD, a collaboration among ARK, FOSC, and NNWB. View the takeaways and the Maryland report on the ARK/FOSC Summer Volunteer Water Quality Monitoring page. Check out the video of the event too.

Spotlight on: Microplastics in our waterways

The impact of microplastics is an important issue in Montgomery County where it is proposed for a section of Ellsworth Drive in downtown Silver Spring. FOSC opposes the use of artificial turf on Ellsworth. See the Ellsworth Synthetic Turf page under the Current Issues page of the Advocacy tab for more information on FOSC’s concerns about synthetic turf.

FOSC Water Quality Committee volunteers have worked to create public awareness on the unseen impact of plastic pollution on humans and on waterways, including fresh waterways such as Sligo Creek. Dr. Jesse Meiller and Dr. Kathy Michels discussed the issue at a February 2020 talk sponsored by FOSC.

Scientists are finding that microplastics are everywhere in our waterways, whether salt water or freshwater. Ongoing research shows that most microplastics are harmful to living creatures and plants life due to their chemical content which does not break down (known as “forever chemicals”.) Synthetic turf is one example of a product that leaches “forever” chemicals as well as plastic bits that are ingested by wildlife.

Report on: ARK/FOSC Summer Volunteer Water Quality Monitoring Program

Summer 2020
Our 2020 summer volunteer Water Quality monitoring partnership with Anacostia Riverkeeper, Corazón Latino, Alliance for the Chesapeake Bay, and Friends of Lower Beaverdam Creek ended in mid September. The program was quite successful, with a variety of volunteers taking turns monitoring two sites along Sligo Creek, and five others in the Anacostia River watershed.
 
The Coliform results were disappointing. I don’t believe any site in the program ever met fishable or swimmable water standards during the summer, though not entirely unexpected given what our FOSC program has found over the years. I will share highlights from the full results on the WQ page shortly. FOSC participated again in 2021, and I think ARK is hoping to expand the scope of the program to new sites and tributaries if possible.

Ongoing Water Quality Committee programs

Volunteers for the Water Quality committee are also running several ongoing programs to help preserve and plan for the health of Sligo Creek:

  • Organizing teams to monitor the chemical and biological health of the Creek.

  • Partnering with area citizen organizations to expand the depth and breadth of our water quality program. This includes FOSC’s 2020 summer volunteer water quality monitoring program, led by Anacostia Riverkeeper and in partnership with Friends of Little Beaverdam Creek, Corazon Latino and the Alliance for the Chesapeake Bay. The program continued in Summer 2021 led by FOSC, NNB and ARK, funded through the Chesapeake Bay Trust and Montgomery County.

  • Running the Water WatchDog program, which provides the public an immediate way to report water pollution as it’s happening to the Montgomery County Parks and Environmental Protection Departments who investigate and may issue fines. Volunteers keep records of contamination events to identify ongoing problems and help resolve them.

  • Educating the public through water quality presentations and monthly monitoring reports.

  • Generating support and advocating for state and local policies that will continue to improve the health of the Creek and its surrounding valley.

Wouldn’t it be great if the water in Sligo Creek were clean enough so that people could wade or swim in it without worry? The FOSC Water Quality Committee is working to improve the water quality of Sligo Creek so that it will meet its potential as a natural and recreational resource. While it is currently home to a surprising variety of wildlife, keeping the creek waters healthy for wildlife is an ongoing challenge as the region becomes more populated.

The Committee and FOSC’s members are working with local agencies and nonprofit organizations to meet the challenge, knowing that a healthier Sligo Creek both enhances our everyday lives and benefits the waters and wildlife of the Anacostia Watershed, the Potomac River, and the Chesapeake Bay.

Are you interested in improving Sligo’s water quality?
Consider joining the Water Quality Committee!

The Water Quality Committee works on projects aimed at understanding and improving Sligo Creek’s water quality.

FOSC’s Chemical Water Quality Team regularly monitors seven sites along the Creek and its tributaries for ten different parameters, keeping track of the Creek’s water quality and the condition of its channel and surrounding habitats. Take a look at the Team’s summary findings in the sample FOSC Water Quality Monitoring Report in the right margin.

We also monitor macroinvertebrates for the Maryland Department of Natural Resources Stream Waders program, the Izaak Walton League’s Save Our Streams program, and the Audubon Naturalist Society program.

We try to learn about and promote Sligo Creek monitoring being done by others, and when appropriate, use our findings to advocate for local, county and regional policy changes. Information about our activities is posted on the Friends of Sligo Creek newsletter and listserv. Join FOSC to receive the newsletter.

If you would like to join the committee, participate in Committee activities or have questions, please email Pat Ratkowski, Committee chairperson, through the Contact FOSC page or email WQ at fosc.org.
