Surface Water Pollutants in order of
frequency of occurence statewide:
1 "Metals" -- (mercury,
cadmium, lead, copper--mostly mercury in the Atchafalaya
area)
2 "Pathogens" -- test indicator
is actually fecal coliforms, which are not normally
harmful by themselves, but are used as an indicator of
the potential for harmful pathogenic organisms.
3 "Organic enrichment/low dissolved
oxygen (DO)" -- the third largest suspected cause of
impairment, responsible for 2,744 miles of stream
impairment.
Lakes: Suspected sources of impairments
in order of frequency of occurrence statewide:
1 "Unknown sources" -- largely
related to metals, sulfate and chloride problems
2 "Natural sources" -- largely
related to low DO, sulfates, and
chlorides
3 "Agriculture"
4 "Municipal point source" --
especially related to pathogens
- with "other related to
pathogens" -- package plants, inflow and
infiltration, wastewater lagoons, grazing, 5 animal
feeding operations, manure lagoons, septic tanks, septage
disposal, marinas, and waterfowl
6 "septic tanks" -- especially
related to pathogens

USGS SAYS WATER SUPPLY WILL BE ONE OF
CHALLENGES IN COMING CENTURY
March 2000 U.S. Water News Online RESTON,
Va.
"The United States and the
world face significant challenges in the years to
come," said Charles Groat, director of the U.S.
Geological Survey. "Over the past century, humans
have become agents of significant change to our planet.
We have reshaped rivers and coastlines. We have brought
new species of plants and animals to places they could
never have reached on their own. And, we have increased
our vulnerability to the extreme events that are part of
Earth's natural processes -- earthquakes, floods,
volcanoes, landslides, droughts, and
hurricanes." As the global population
continues to grow, he added, people will place greater
and greater demands on the resources of our planet,
including mineral and energy resources, open space,
water, and plant and animal resources. As a result of
these changing demands and needs, said Groat, USGS
scientists see many scientific challenges for the next
century.
Safe, clean water
Safe drinking water is vital to the
health of citizens in every community. Reliance on water
treatment plants and chlorination is important to safe
drinking water but it is clear that strategies must go
beyond treatment to protection of water sources.
Increasing urbanization of land used as sources of
drinking water, microbial pathogens resistant to
chlorination, and proliferation of new synthetic chemical
compounds that may have adverse health effects, are
challenging the effectiveness of treatment
technology.
The 21st century will see increased
awareness that drinking water supplies are whole systems
that include source-water areas, groundwater wells and
surface water intakes, treatment plants and distribution
systems. USGS scientists are helping communities
protect their drinking water sources by designing
computer models and other tools and conducting research
to help communities identify, manage, and protect source
water areas.
Continual development and production
of new chemical compounds has dramatically improved food
quality, human health, and our daily lives. Increasing
knowledge of the close relationship between human
activities and the environment has made it clear that the
chemical compounds we use can find their way into the
nation's water resources. Preliminary results from a USGS
study indicate that many compounds commonly used in
everyday life are turning up at very low concentrations
in streams across the country.
Examples of some of the compounds
found to date include acetaminophen, caffeine, codeine,
cotinine (a nicotine metabolite), 17b-estradiol (a
hormone), and sulfamethoxazole (an antibiotic). For many
of these compounds, the USGS study will provide the
earliest data on their environmental occurrence in the
nation. The impacts of these chemicals on humans or
aquatic life, at the low concentrations they are found in
the environment, are generally unknown, but the USGS is
working in partnership with health and environmental
science agencies as the study proceeds.
A major scientific issue in the
early part of the 21st century will be the eutrophication
of water -- the presence of excess amounts of the
nutrients nitrogen and phosphorus that cause increased
growth of aquatic plants, which consume the dissolved
oxygen in water needed by other aquatic life. Growth of
the human population will increase the demand for food.
This will in turn lead to further increases in the use of
fertilizers, which could put even more stress on coastal
areas, as well as freshwater bodies.
USGS scientists are measuring the
transport of nitrogen and phosphorus to coastal areas by
major rivers to determine how much of the nutrients that
enter the streams actually move downstream and how much
is lost or transformed to harmless forms.
The nation's water infrastructure
The objectives for the nation's
infrastructure of dams, levees, navigation systems and
diversions for water were developed between 1930 and
1970, with an emphasis on water for agriculture, electric
power, navigation, flood prevention, water for cities and
industry and dilution of wastes. These objectives are
still valid, but the values and laws under which these
systems operate today have a number of added objectives:
enhancement of aquatic and streamside or riparian
habitat, recreational opportunities and a general desire
for preservation of natural environments for future
generations.
These challenges will require
scientists to collaborate with water managers to predict
how changes in the management of our water infrastructure
will affect its traditional goals and serve the newer
environmental goals. USGS scientists are looking at the
physical and biological results of modifying or removing
these systems.
Coastal waters -- pristine or
polluted?
The earth's seemingly boundless
oceans and scenic coastlines have limits. The oceans
cannot provide unlimited fish to feed growing
populations, nor can they absorb unlimited wastes from
human activity. As population growth near and adjacent to
the coasts increases water quality and ecosystems are
impacted and vulnerable shorelines are eroded. Algal
blooms, oxygen deficient zones and Pfiesteria are some of
the negative impacts resulting from excess nutrients that
end up in coastal waters.
Even after discharge waters are
cleaned up, previously deposited contaminated sediments
on the sea floor can be "churned up" by storm
waves and continue to negatively impact the offshore
ecosystems. USGS scientists are locating, characterizing
and quantifying how these sediments and associated
contaminants are distributed.

waters
Black Lake Watershed
Watersheds with More Serious Water
Quality Problems --Watersheds with aquatic conditions
well below State or Tribal water quality goals that have
serious problems exposed by other indicators.
Watersheds with Lower Vulnerability to
Stressors -- Watersheds where data suggest pollutants
or other stressors are low, and, therefore there exists a
lower potential for future declines in aquatic health.
Actions to prevent declines in aquatic conditions in
these watersheds are appropriate but at a lower priority
than in watersheds with higher vulnerability.
