Fact Sheet Available for Fish Pond (Aquaculture) Water Quality

The Arkansas Water Resources Center (AWRC) has published its second fact sheet – this one is on collecting your water sample and interpreting the results for the fish pond analytical package offered by the AWRC Water Quality Lab.
 
You probably know that good water quality is important for optimal fish production – but, how is “good water quality” defined? The fish pond fact sheet describes just that – the water quality parameters that are important for fish growth, and how much of these constituents should be in the water.
 
You can compare your water sample results provided by the Lab with the information in the fact sheet.
 
To view the Fish Pond fact sheet, visit the
AWRC website. For more information, you can contact your extension specialist about your analytical report and any results that may be of concern.
 
The Lab offers several analytical packages that include parameters important for other specific uses such as irrigation or livestock watering. Stay tuned for upcoming fact sheets for these other packages.
 
Visit the
Lab webpage to view the water sample submission form for a full list of parameters and packages that the Lab offers.

Researchers Study Harmful Chemicals in Drinking Water Systems

The Problem: We all need clean drinking water to survive, but many of us also probably take it for granted. However, drinking water treatment plants are constantly trying to stay ahead of the latest contaminant threat and some researchers are looking more and more at the distribution pipes as a source of new problems.
 
Biofilms, which are a collection of living and dead material, including bacteria and fungi, can actually form inside of pipes that pump clean drinking water from the treatment plant to your house. If not managed properly, biofilms can cause corrosion issues and allow harmful bacteria to grow and potentially contaminate the water supply.
 
But there are other chemical reactions that can take place with these biofilms in water distribution pipes. The formation of disinfection byproducts (DBPs) is one example. DBPs are a group of potentially harmful chemicals that form when disinfectants such as chlorine or chloramine react with other chemicals during water treatment or even in distribution pipes.
 
So What?: Nitrosamines are a group of DBPs that are known carcinogens, and can make people sick even at the very low levels they tend to form. So far, not a whole lot is known about where and how nitrosamines are formed, especially the potential for them to form from biofilms in distribution pipes.
 
The Research Question: Dr. Julian Fairey, associate professor, and David Meints, former graduate student, in the Department of Civil Engineering at the University of Arkansas, wanted to know: do nitrosamines form in biofilms lining distribution pipes?

Oklahoma Attorney General Scott Pruitt Nominated to be the United States EPA Administrator
By Walter Wright, Mitchell Williams Law Firm

Scott Pruitt, the Attorney General from our neighboring state of Oklahoma has been nominated by President-Elect Trump to be the next United States Environmental Protection Agency (“EPA”) Administrator.
 
Upon expected confirmation by the United States Senate, Mr. Pruitt will replace current EPA Administrator Gina McCarthy who has served in the position since 2013.
 
The Administrator heads EPA and is customarily provided cabinet rank by the President.
 
EPA was established in 1970 by President Nixon when he signed Reorganization Plan No. 3.  The federal agency implements most of the federal environmental statutes such as the Clean Air Act, Clean Water Act, Toxic Substances Control Act, Resource Conservation Recovery Act, Federal Insecticide Fungicide and Rodenticide Act, etc.  Standards promulgated by the agency pursuant to several of these statutes provide baseline requirements that the states implement.
 
Mr. Pruitt became Oklahoma Attorney General in 2011.  His public service has also included serving several years in the Oklahoma Senate.  Other activities have included co-ownership and managing general partner of Oklahoma City’s Triple-A minor league baseball affiliate, Oklahoma City Red Hawks and a private law practice which focused on Constitutional Law.

Site Specific Nutrient Criteria Approved for Beaver Lake
By Angela Danovi, Beaver LakeSmart

On November 10, 2016, ADEQ announced the EPA completed its review of the Arkansas Regulation 2, which establishes water quality standards for surface waters throughout the state of Arkansas. As part of the review process, EPA approved most of the proposed revisions to the regulation including adopting site specific criteria on Beaver Lake. The provision found in section 2.509, Nutrients, states the site-specific criteria to be:
  • Growing season geometric mean of chlorophyll a concentration: 8 µg/L
  • Annual Average of Secchi transparency: 1.1 meters
for measurement at Hickory Creek site over the thalweg, below the confluence of War Eagle Creek and the White River in Beaver Lake.

2017 SEC Academic Conference
Mississippi State University will be the first Southeastern Conference institution to host a new academic event focused on SEC university research collaboration.

To be held at the Starkville campus, the 2017 SEC Academic Conference will focus on “The Future of Water: Regional Collaboration on Shared Climate, Coastlines, and Watersheds.”

The conference aims to identify the dominant economic, community and ecosystem challenges to sustainable water resources in the southeastern U.S.; identify policy and practice paths to maximize the health and vitality of the region through water stewardship; and engage the best and brightest scientists in the SEC with other national and international experts in water resources.
