USGS geoHEALTH Newsletter Special Issue on Algal Toxins
This edition of the 6eoHEALTH Newsletter (Volume 15, Issue 3, 2018),
features the USGS's Toxic Substances Hydrology and Contaminant
Biology Programs' collaborative science within and outside the USGS
with a focus on harmful algal blooms. This work is used by
stakeholders to understand why, when, and where toxic algal blooms
occur and how to mitigate environmental exposures to toxins that
adversely impact local economies and the health of fish, wildlife, and
the public.
EPA and USDA Collaborative Approaches to Address Nutrients
To better address this challenge, the EPA and the USDA are working to
identify opportunities for meaningful reductions in nonpoint nutrient
losses and improvements in water quality. These opportunities will
require using all the tools available to address excess nutrients in
watersheds, including non-regulatory and market-based programs. The
EPA and the USDA are committed to working together to improve water
quality while improving the efficiency of land use practices and
optimizing treatment technologies and invite each state environmental
and agricultural agency to engage with the EPA and the USDA to
identify local opportunities and challenges to reducing excess nutrients
in watersheds and improving water quality.
Milford Watershed Regional Conservation Partnership Project
(RCPP^
The Natural Resources Conservation Service (NRCS) in coordination
with the Kansas Water Office recently signed a Regional Conservation
Partnership Project (RCPP) agreement that will bring partners together
to work with NRCS on implementing conservation practices within the
Milford Lake Watershed. The agreement will bring financial resources
and incentives to help agriculture producers make upgrades to protect
the watershed and shorten the duration of HABs on Milford Lake. The
Kansas Water Office is the lead partner, and numerous regional entities
are contributing to the project.

BLOOMS, BEACH CLOSURES and HEALTH ADVISORIES, DECEMBER 2018
The following map includes blooms, cautions, warnings, public health advisories, closings and
detections over State's threshold, due to the presence of algae, toxins or both. This is not a
comprehensive list, and many blooms may have not been reported or are not actively monitored as
many States close the season for Harmful Algal Bloom monitoring efforts by the end of October.
