2025 Water Quality Testing Results
NNWB partners on Anacostia Riverkeeper's (ARK) summer water quality monitoring program at several sites along the NWB, measuring e coli, turbidity (cloudiness, such as sediment), pH, dissolved oxygen, temperature and specific conductivity. The 2025 results are here. ARK also posts the results on a map here.
