(May 1, 2018) - The US Geological Survey (USGS) hosted an annual National Water-Quality Assessment (NAWQA) meeting in Washington DC last week to discuss critical water quality issues and emerging scientific applications throughout the country. The focus of this year’s meeting was to share recent scientific findings and needs surrounding harmful algal blooms (HABs). HABs can produce toxins and have the potential to negatively impact public health, the environment, and the economy
As mentioned during the meeting, scientists are now turning to emerging technology such as using drones and satellite imagery to help predict the development and formation of algal blooms in a more proactive manner. There is also ongoing research on how nutrient flowpaths can impact downstream water quality. For example, studies show legacy nutrients are collecting in the infilling/sedimentation of freshwater reservoirs and how groundwater is contributing to increased nutrient loading in streams.
NACWA members with questions or would like to obtain some of the USGS research, please contact Emily Remmel.
