Estuarine Processes, Hazards, and Ecosystems

Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S....

Is Uranium in Water Resources near the Grand Canyon a Health Hazard?

The public worries that uranium in natural geologic formations, mine tailings, dusts, water, and other geologic materials can pose a health hazard to humans and wildlife.

Our specialized teams of hydrologists, chemists, and geologists working together at a field site in the Grand Canyon region of the United States have shown:

Elevated uranium concentrations (above the drinking...

Can There be Unintended Benefits when Wastewater Treatment Infrastructure is Upgraded?

Science from the U.S. Geological Survey (USGS) and other entities has shown that a mixture of natural and synthetic estrogens and other similar chemicals are discharged from wastewater treatment plants (WWTPs) to streams and rivers.

USGS and University of Colorado hydrologists, chemists, geologists, and biologists studied the chemistry and biology of Boulder Creek downstream of Boulder ...

Are Spills from Swine Lagoons Causing Downstream Health Hazards?

There are no national databases or tracking of the number or frequency of manure spills in the United States. Some past spills have been shown to result from events such as equipment failures, over-application of manure to agricultural fields, runoff from open feedlots, storage overflow, accidents with manure transporting equipment, severe weather events, or possibly deliberate actions....

What Are the Health Hazards from Contaminants Released to the Environment by Natural Disasters?

Our specialized teams of hydrologists, chemists, and geologists working together at field sites in Northeastern US after Hurricane Sandy have shown:

  • Metal contaminants were released to the environment after Hurricane Sandy due to some dune restoration activities.
  • In other locations the storm actually decreased contaminant exposures to bottom dwelling aquatic biota.
  • ...

Are Naturally Occurring Microbiological Toxins in Water Resources a Health Hazard?

A growing number of human gastrointestinal, respiratory, dermatologic, and neurologic effects, as well as dog and livestock illnesses and deaths, in the United States have been linked to exposures to algal blooms in recreational lakes and stock ponds.

Some of the blooms contain cyanobacteria, which have the potential to produce cyanotoxins in freshwater systems. However, the connection...

What is the Chemical and Microbial Content of Our Tap Waters?

Safe Drinking Water Act compliance addresses the safety of public-supply water systems. The composition of public-supply drinking water is generally only tested at the treatment plant, and not at the tap after traveling through the water distribution system. Only lead and copper are tested at a subset of residential and other taps. Testing of water in private wells is rare unless local health...

Are Tumors in Wild Fish Harvested in the Great Lakes Region Related to Contaminants in Water Resources?

Our specialized teams of scientists are working in our laboratories and at field sites around the Great Lakes in collaboration with other federal and state resource agencies to document the prevalence of skin and liver tumors. Tumor prevalence in white suckers (Catostomus commersonii), a fish harvested as a food source by local communities, is related to the degree of urbanization in watershed...
