Ward Labs data request experiment

[Silver_Is_Money]

For Ward Labs reports only, please report the result of the highlighted division.

Total Hardness, CaCO3 ÷ Total Dissolved Solids (TDS) Est, ppm =

Then also please report whether your Ward Labs report is for Tap or Well Water.

Note: Please do not participate in this experiment if your Ward Labs water report is for softened water, or RO water, or blended water, or "made-up" water, or anything other than straight Tap or Well water.

I'm conducting this brief period only data gathering exercise whereby to rather quickly determine if there is, or is not, any sort of meaningful correlation between TDS and Hardness for Ward Labs derived data.

The reason why I desire to restrict this to Ward Labs data only is because I can trust that it is not data that is averaged across either of seasonal variation or multiple blended sources, but rather is single sourced.

[Nagorg]

Tap water:

Date: 05/2021
--------------------------------------------------
Total hardness, CaCO3 = 9
Total Dissolved Solids (TDS) Est, ppm = 825

9 / 825 = 0.0109
--------------------------------------------------

Date: 02/2018
--------------------------------------------------
Total hardness, CaCO3 = 126
Total Dissolved Solids (TDS) Est, ppm = 335

126 / 335= 0.3761
--------------------------------------------------

Date: 04/2016
--------------------------------------------------
Total hardness, CaCO3 = 88
Total Dissolved Solids (TDS) Est, ppm = 383

88/ 383 = 0.2297
--------------------------------------------------

OK, I'm definitely seeing a lot of rather random data scatter so far. After a few more I may call this as one over, a bit earlier than I had hoped. My thanks to all who have contributed so far! Likes to all.

 

[Chorgey]

Ward Labs Report for Laurel Springs, NJ tap water

Total hardness, CaCO3 = 58
Total Dissolved Solids (TDS) Est, ppm = 115

58 / 115= .5043

 

[AkTom]

Well water
Total hardness CaCO3 1012
TDS 2226
1012/2226 = .454
I know, I have HORRIBLE water. I buy bottled water.

 

[Deric]

Tap Water

Total hardness, CaCO3 51
TDS 83
42/83=.614

I've got more if you think there's value. I've always used Ward Labs for my analysis.

FWIW, I have been in the habit of recording these over time. On brew day, I'd measure TDS and use that as my guide for the closest water profile match and adjust accordingly.

Even then, I'd still blend 40% Tap water to 60% DI and make my adjustments off of that. But now I've simply been using 100% DI and building off of that.

It would be awesome if my water didnt suck for brewing. But it does so I adjusted...

Hardness (primarily dissolved calcium and magnesium) is a component of the Total Dissolved Solids... so yes, they are correlated. High hardness will cause a high TDS for example.

Sweet mother of pearl. You're not kidding!

This correlation is a given, but it is not the correlation I seek.

Sorry - didn't notice you were the original poster...

No worries! No harm, no foul.

 

[RobP]

Ravenna, Ohio TDS: 290. CACO3: 146

 

[Silver_Is_Money]

I haven't made any effort to analyze the hardness/TDS data yet, but as more values come in I'm beginning to suspect that they may eventually average to around 0.50, but with no meaningful correlation to be gleaned beyond averaging.

I was hoping that one might be able to derive an approximation of their waters total hardness if all they know is its TDS, but it is becoming quite evident that such is impossible.

 

[d40dave]

Tap water, TDS: 524 CACO3: 399

I believe you are correct -

 

[blkmagik98]

Denver, CO tap water;
Total Hardness, CaCO3 123
Total Dissolved Solids (TDS) Est, ppm 218
0.564

 

[Grizwold1]

CaCO3:155
TDS: 164
0.95

 

[rallenhall]

Henry Co OH Well Water

Total Hardness = 538
TDS = 933
538/933 = .577

 

[Silver_Is_Money]

The results span from nearly 0 to nearly 1, and as such appear to 'potentially' average to 0.5, so I'm calling this brief experiment over.

 

[Imhoppy]

It ain't over till the fat lady sings, lol.

Davenport, IA tap water (sampled October 2021)

Total Hardness, CaCO3, ppm = 199
Total Dissolved Solids (TDS) Est, ppm = 282

199/282 = 0.706

 

[day_trippr]

I use 100% home-grown RO for brewing, but some of ^those numbers^ make me feel better about my own!

Cheers!

 

[Oleson M.D.]

North Texas city tap water, from a local lake. Info provided by the City of Denton Municipal Laboratory. Not averaged data, but a single snapshot in time.

Ca = 38
Calcium Hardness = 92
Mg = 4
Magnesium Hardness = 14
Sodium = 19
Sulfate = 34
Total Hardness = 106
TDS = 95

Multiple award winning beers have been brewed with this water, untreated, except for carbon filtration. I guess our water is not so bad after all!

Old thread but I can finally contribute.

Well water, East Hampton, NY (July 2022 test)
