TDS Meter - My Readings
Posted 20 July 2010 - 19:28 PM
Tap Water - 421 ppm
Filtered Water from Samsung Fridge/Freezer - 322 ppm
Fresh water spring - 349 ppm
Stream - 285 ppm
Rain - 25ppm
Water from Tumble Dryer - 22ppm
Boiled tap water - 422 ppm
Tip:- Dont use boiled water!
I think the reason its got up is because it has solids round the edge from previous times the kettles been set to boil. Its a bit wierd though =/

Tap water also varies greatly throughout the UK and even on a day to day basis. For instance, the tap water where I live is often approx 100PPM but increases after a storm, due to field water being washed into streams/rivers. Scotland usually has a low water PPM due to the rock geology, which is primarily granite; however, places which have a lot of limestone will typically have a high water PPM.

As I live in Cheltenham, the Cotswolds are famous for limestone! That explains it!
Ive had a plant living in the tap water here for about 3 months, it grew fine. No better than it does today!

If you'd like to compare some values with mine in Northern Germany, here are the readings of my cheap conductivity meter:
Local tap water: 451 µS/cm
Water in my rain barrel: 90 µS/cm
Destilled Water (purchased in plastic canister several years ago): 1 µS/cm
Water from electronic dehumidifier: 19 µS/cm
If you prefer ppm readings I think you have to divide the numbers by two.

I know! I am out of water! I have to take the PPMs of my fish tank (I think it is around 100 which should be ok I guess until it rains - eep!
