[Adding water quality analytes to GSS]

Thanks, Brian,

Appreciate your help. I've been able to add the analytes of interest.

Kind regards,

[Adding water quality analytes to GSS]

Hi All,

 

I've been attempting to add water quality measures such as Total Nitrogen and Total Phosphorus to GSS. As these measures are an aggregate of different constituents I cannot specify a molar mass.  I have attempted to add them as a user-defined analyte and specified concentration and the units in mg/L. However, when I go to add these analytes to GSS the unit's default to mmol/l. I'm sure I've been able to add these measures in the past but have come up short. Any tips/guidance would be much appreciated.

Kind regards,

Clint

[User Defined Analytes and Total Alkalinity]

Hi All,

 

It has been a few years since I last used GWB. I'm looking forward to getting started again!

 

I've been having a few difficulties with loading up a large number of user defined anlaytes. Specifically, I want to add the following:

 

Site ID Abs. 440 nm B (mg/L) Ca (mg/L) Mg (mg/L) Na (mg/L) K (mg/L) SO4 (mg/L) Cl (mg/L) F (mg/L) I (mg/L) FeII (mg/L) MnII (mg/L) Si (mg/L) D.O. (mg/L) d13C-DIC (‰, V-PDB) DIC (mmol/L) DNPOC (mg/L) NPOC (mg/L) TOC (mg/L) SpC (us/cm) Total Hardness (mg/L, CaCO3) d18O-H2O (‰, V-SMOW) d2H-H2O (‰, V-SMOW) DKN (mg/L) TDN (mg/L) TKN (mg/L) TN (mg/L) ORP (mV) Turbidity (NTU) Water Temp. (◦C) pH Talk (mg/L) HCO3 Alk. (mg/L) Carbonate Alk (mg/L) Br (mg/L) Cd (mg/L) Clarity B.D. (m) E. coli (CFU) Faecal Coliform (CFU) NNN (mg/L) Nitrate-N (mg/L) Nitrite-N (mg/L) TAM (mg/L) DOP (mg/L) DRP (mg/L) TDP (mg/L) TP (mg/L) SSC (mg/L) TSS (mg/L) VSS (mg/L) Zn (mg/L), Abs. 440 nm B (mg/L) Ca (mg/L) Mg (mg/L) Na (mg/L) K (mg/L) SO4 (mg/L) Cl (mg/L) F (mg/L) I (mg/L) FeII (mg/L) MnII (mg/L) Si (mg/L) D.O. (mg/L) d13C-DIC (‰, V-PDB) DIC (mmol/L) DNPOC (mg/L) NPOC (mg/L) TOC (mg/L) SpC (us/cm) Total Hardness (mg/L, CaCO3) d18O-H2O (‰, V-SMOW) d2H-H2O (‰, V-SMOW) DKN (mg/L) TDN (mg/L) TKN (mg/L) TN (mg/L) ORP (mV) Turbidity (NTU) Water Temp. (◦C) pH Talk (mg/L) HCO3 Alk. (mg/L) Carbonate Alk (mg/L) Br (mg/L) Cd (mg/L) Clarity B.D. (m) E. coli (CFU) Faecal Coliform (CFU) NNN (mg/L) Nitrate-N (mg/L) Nitrite-N (mg/L) TAM (mg/L) DOP (mg/L) DRP (mg/L) TDP (mg/L) TP (mg/L) SSC (mg/L) TSS (mg/L) VSS (mg/L) Zn (mg/L)

 

So far I can add the normal basis species. However, when I need to specify user defined analytes, of which I have many, I'm finding that GWB is using mmol/kg as default units. I've attempted to edit these to specify mg/L but it defaults back to mmol/kg. An additional issue, and perhaps the root cause (?), is that I do not have molar mass for some of these species (e.g., Total Organic Carbon, Dissolved Non-purgeable Organic Carbon etc).

 

Secondly, I was wondering how folk deal with adding measures of carbonate alkalinity into GSS? The lab data we use reports Total Alaklnity (mg/L as CaCO3), Bicarbonate Alkalinity and Carbonate (CO3) Alkalinity. As GWB uses alkalinity to assign major ion facies I was hoping someone had experience with adding alkalinity measures (all 3)?

 

Any pointers on either of the above would be gratefully received.

 

Kind regards (Cheers),
