You're right. People kill people.
Ignorance kills people. And greed.

He is concerned about *his* tortoise, doesn't want to poison it with

Typical. All about me and mine, who gives a shit about them. Feh!

As I already wrote, NATURAL minerals have made the ground water in this
area naturally toxic. It is unfit for irrigating crops, let alone
drinking by humans or animals.

Which minerals are causing the toxicity and is their source naturally
occuring or a result of man's activity?

Mostly NATURAL sufites and sulfates. (How many times do I have to say
that they occur naturally?) There are also nodules of phosphate that
explode spontaneously.

When schools were built in my community, the grading contractor had to
dig down about 5 ft and haul away the native soil. Then, he had to
bring in soil from elsewhere to fill the holes. It was considered
unsafe to build a school on the native soil.

During a drought about 20 years ago, it was suggested to augment our
water supply (imported from northern California) with well water. Even
mixing only 1 part well water with 9 parts imported water would yield a
witch's brew that could not be used for drinking.

Not all toxics in our environment are the result of human activity.
