Water Quality Monitoring Classes
For more information about the program in D.C. and Maryland, please email Cathy Wiss, Water Quality Monitoring Program Coordinator (pictured right).

For more information about water quality workshops in Virginia, email Dan Schwartz with the Northern Virginia Soil and Water Conservation District.

A nominal fee of $15 per class will be charged for nonmembers of ANS. This fee can be waived for students earning SSL credit.


Class Schedule

Introduction to Water Quality Monitoring  
Find out about monitoring with ANS! One classroom session and the field workshop are recommended for those interested in becoming monitors.
Classroom Session
Woodend Sanctuary, Chevy Chase, MD
Section B: Thursday, March 16 (7-9:30 pm)
Section C: Wednesday, May 17 (7-9:30 pm)
(Both Sections B&C cover the same material)
Fee $15, waived for members and students earning SSL credit
In the classroom, we will explore how benthic macroinvertebrates – bottom-dwelling boneless creatures – help us assess the health of local streams and learn how to identify these organisms to the taxonomic level of order by examining preserved specimens. Registration required.
Field Workshop
Section A: Sunday, March 19 (1-4 pm) site TBA
Section B: Sunday, May 21 (1-4 pm) site TBA
Fee $15, waived for members and students earning SSL credit

In the field workshop, we will visit a stream to practice monitoring techniques and then collect and identify the macroinvertebrates we find. Registration required. 

Aquatic Insect Family ID  
Woodend Sanctuary, Chevy Chase, MD (7-9 pm)
Section A: Tuesday, January 31 - Caddisflies 
Section B: Tuesday, February 7 - Beetles & Megaloptera
Section C: Tuesday, February 14 - Dragonflies, Damselfies & True Flies
Section D: Tuesday, February 21 - Mayflies
Section E: Tuesday, February 28 - Stoneflies & Review
Fee $15 for each section, waived for members and students earning SSL credit
Deepen your benthic macroinvertebrate identification skills to the taxonomic level of family through this series of five classes. Identification of these organisms to family level greatly enhances the water quality assessment power of our data and gives us a better reading of aquatic insect diversity. Registration required. 

Macroinvertebrate ID Review & Quiz  
Woodend Sanctuary, Chevy Chase, MD
Section A: Thursday, March 9 (6:30-9 pm)
Section B: Saturday, March 11 (9:30 am-12 pm)
Section C: Tuesday, March 14 (6:30-9 pm)
(Sections A, B & C cover the same material)
No fee
Time to separate the stoneflies from the mayflies! Those who wish to be certified to identify macroinvertebrates in the field must demonstrate their ability annually by taking a quiz using preserved specimens. Those who do not take the quiz may still be assigned to a monitoring team to assist with data collection and other field logistics, but only those who have taken and passed the quiz will identify macroinvertebrates for data recording. Registration required.

How to Read Your Stream 
Tuesday, March 28 (7-9:30 pm)
Woodend Sanctuary, Chevy Chase, MD
Fee $15, waived for members and students earning SSL credit
Learn about the influence of land uses on streams, stream character and dynamics, bank erosion, bar formation, substrate composition, different velocity-depth regimes, and the importance of riffles and riparian vegetation. This class is recommended for anyone who plans to participate in the ANS water quality monitoring program and is a good refresher on habitat assessment for experienced monitors. Registration required.  

Know Your Invasive Plants 
Saturday, May 13 (9:30 am-noon)
Woodend Sanctuary (Teale), Chevy Chase, MD

Fee $15, waived for members and students earning SSL
Invasive plants that kill or bring down mature trees can seriously alter stream healthand ecosystem function. Volunteer Master Naturalist Diyan Rahaman will help you identify non-native invasive plants at Woodend and in nearby Rock Creek Park. Registration required. An ANS/Rock Creek Conservancy Partnership.
