River Water Quality
River Water Quality
(OP)
I teach a class that includes a section on Oil & Gas industry Produced Water Disposal. The class is very much U.S.-centric, but I teach it in international locations.
One of the slides compares Water Quality standards, to a local river near my home, to the quality of produced water in a CBM (Coalbed Methane or Coalseam Gas) field. I was looking to change my example river from U.S. to somewhere on another continent, but I've been unable to find a Cation/Anion analysis with TDS, pH, and turbidity for a major river. I'd like to use the Thames, Danube, Nile, Amazon, or the Yangtze, or any river that has wide recognition around the world, but I have been wildly unsuccessful finding any gross-level information on any major river that is used for a municipal water supply. I can find a lot of information about the specific trace elements that people are concerned about today, but not Sodium or pH.
Does anyone have an example water analysis from a major river that they would be willing to share? Thank you.

If you want more details than this, you can send an email to the water supplier.

Temp = 18.4 deg C
pH=7.11
NO3= 0.287
NH3=2.416 mg/L
Turbidity = 7.5 NTU
TSS=20 mg/L
TDS= 8 mg/L
BOD= 7.95 mg/L O2
DO=4.07 mg/L
No flow data, but average flow in 7/2008 was 11 m3/sec (or 228 MGD).

I guess I'm going to have to dig into this further.

Sorry about that, the numbers for TDS/TSS I posted I'd read wrong.
In 7/09 in the Vardar:
TDS (Total Filterable Residue) was 365 mg/L
TSS (Total Non-Filterable Residue) was 385 mg/L.
Please ignore the previous TDS and TSS values.
