I cant imagine levels that high..
560 to 900 depending on the season and source blends here in Phoenix. The southwest parts of the Valley can exceed 1200-1600.
The number really doesn't tell the story though, it could be all calcium or other beneficial elements or it could be all phosphates, silicates or copper. That's the problem with TDS measurement, it's not anything specific, only that something or some things electrically conductive are present. This is why 0 TDS is your goal so you know you only have pure water and nothing else. 3 TDS could be calcium or magnesium or it could be silicates, you have no idea.

I am using changing color resin and changing filters every 150-200gl as the water is at about 170ppm these days, but I know I am about to run into problems as we are hit by the worst drought in a decade or so.
Normally, the flow of water from the rains and dams keeps saltwater from the Gulf of Thailand at bay. But during droughts, the saltwater creeps upstream, turning the Chao Phraya river brackish and then hit us hard.
Well, I am getting used to it, during summer I always store 100gl of ro/di water to help me cope with the situation.

I also find it interesting that so many environmental thing impact the tds in all the different areas.
