I'm sure they'd love to pursue perfection if they were paid decent wage and not pressured to be as fast / cheap as possible.
It's easy to talk about perfection while sitting in a air conditioned office and slightly pressing on buttons while looking at a screen and getting paid 4-10 times the minimum wage these guys are getting while busting their asses outside no matter the weather.

Many things can be off with water coming from a well. Pollution, bacterias, &c. I hope you test / treat it often, otherwise it's not much safer than drinking tap water.
