There is no direct conversion between conductivity, temperature, and total dissolved solids (TDS). Conductivity is often used as a proxy for estimating TDS, especially in water quality monitoring. TDS can be estimated using a conversion factor based on the specific characteristics of the water sample, but it is not a precise conversion. Temperature can affect conductivity readings, so it's essential to measure both parameters accurately when estimating TDS.
almost 100% of people in the us have accsess to clean water
Yes they do or most people would be dead.
Because the polluted air make it harm for drinking for us
there is none they have polluted water every wear but in some countries they have a higher risk of polluted water
About 264.2 (US) gallons.
Because the polluted air make it harm for drinking for us
Yes it should be. Water goes through many purification stages before it reaches your tap, so you should be fine.
Water was safe to drink but the bombs had destroyed the water plants therefore the people had no water and the US delivered 15 million gallon a day.
5.7 US gallons of water.
4.36 US gallons of water.
I don't think people in the U.S. use too much water.
