I lived many years in the desert. The problem wasn't toxic water, it was water period. Hard to find. Also, there were no green pastures. What make you think Pslam 23 is about the desert? The entire Psalm is portraying the Shepherd as bountiful provider and protector, referring to covenant people as His flock---as scripture often does.In a desert, a shepherd still has to make sure the water is not toxic. The footage of THAT THE WORLD MAY KNOW showed examples. The example was given of the cattle drive from TX to COL in which the pointman had to quickly determine toxicity and divert 5000 head.
Not only that, but on the farm I lived on growing up we had a small flock of sheep. There was a pond in the pasture. In the same pasture, northwest of the pond was a creek, fed by an artesian spring, that also fed the pond. Below the dam was another artesian spring, that kept that area swampy, so the sheep would not drink from that. Neither would they drink from the creek, even though it was narrow and shallow and slow moving. They drank from the pond only.
