The meter showed 2.27ppt
Let do some conversion here.
1 ppt = 1000 ppm
1 ppm = 1 mg/L
Therefore, 2.27ppt is equal to 2270 mg/L. And let see what US EPA guideline said. According to the US EPA the maximum allowable TDS in the drinking water is 500 mg/L. It mean, the water that supply from the desert local authority is NOT suitable for drinking.
Let say, everyday we drank 1 litre of water which contain TDS of 2270 mg/L, it means our body actually consumed 2.27g of solid substance. In 1 years, our body consumed almost 830g of solid substance and our kidney needs to work hard to filter these rocks from our body. But there will be higher chances to get kidney stones, gall stones and hardening of the arteries.
So now you know what I want to sell in the desert? XD
