Jordan River Water Quality Study

Wednesday, January 4th, 2012
picture-15

This water quality study for the Jordan River establishes the Total Maximum Daily Load (TMDL) for Total Organic Matter (OM) of 3,983 kg/day that will achieve the model endpoint for Dissolved Oxygen (DO). This target concentration is defined in a water quality model (QUAL2Kw) which is being used as a decision support tool for restoring beneficial use to the lower Jordan River. Additional testing was conducted to quantify uncertainty of input parameters and rates used in the calibrated model. Based on these results and additional information reviewed during the TMDL process, a 1.0 mg/L implicit Margin of Safety (MOS) was added to the Jordan River instantaneous DO standard of 4.5 mg/L. Input concentrations of Total OM that resulted in meeting the model endpoint of 5.5 mg/L DO were used to define permissible loads to the lower Jordan River. This model endpoint and the resulting permissible loads account for levels of uncertainty that exist in the TMDL process at this time and are designed to maintain DO levels in the lower Jordan River above the instantaneous DO standard.

NATURAL RESOURCES DEFENSE COUNCIL
An estimated 10 trillion gallons a year of untreated stormwater runs off roofs, roads, parking lots, and other paved surfaces, often through the sewage systems, into rivers and waterways that serve as drinking water supplies and flow to our beaches, increasing health risks, degrading ecosystems, and damaging tourist economies. But cities of all sizes are saving money by employing green infrastructure as part of their solutions to stormwater pollution and sewage overflow problems

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
