These chemicals depend on the rocks forming the aquifer
The rainwater contains minerals from the clouds, walls of rainwater tanks etc, thy just do. But water from a tap (unless bore water) Has no minerals in them and is clean and has no minerals.
You have to be careful with bore water as the minerals in it may give you trouble The best thing to do is get a sample of the stuff assessed by a pool shop and find out if there is any problem with it and what to do about it if there is.
Bore well water may contain naturally occurring minerals like calcium, magnesium, iron, and manganese. It can also have contaminants such as bacteria, viruses, nitrates, and pesticides depending on the surrounding environment and land use practices. Testing the water quality is important to ensure it is safe for consumption.
The pH level of bore water can vary depending on factors like mineral content and surrounding environment. Generally, bore water has a pH level between 6.5 to 8.5, which is considered slightly acidic to slightly alkaline. Testing the pH of bore water is recommended to understand its specific characteristics.
silica
The water in Alice Springs comes from the Great Artesian Basin, part of which lies underneath the town. The towns water supply itself comes from the Jay Creek Bore, south west of Alice Springs. The water itself is quite rich with minerals, and is very nice drinking.
well you just do who knows?
Bore water
liquid (e.g. water) and minerals.
Veins carry water and minerals
Soft or hard water has to do with the amount of dissolved minerals in water and what those minerals are. "Harder" water has more dissolved minerals (like calcium.)
Food contains minerals. Pure water (perfectly distilled water) contains no minerals, but naturally occurring water (lakes, oceans, streams, underground water) contains dissolved minerals.
