Sulfur water

Some adverse effects that have been found include dehydration, with excess amounts of sodium or magnesium sulfate in a person's diet according to a study in 1980, with some populations, such as children and elderly people, being seen as higher risk.

A survey was done in North Dakota US to better derive whether there was direct causation of a laxative effect from having sulfur in drinking water.

[4] According to the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC), drinking water with high levels of sulfate can cause diarrhea, especially in infants.

[5] At the University of Wyoming in America, sulfur water was studied to see the effects it can have upon the performance of steers that are on a forage-based diet.

To reduce the extra sulfur in the ruminant's diet, ruminal bacteria break the excess down, resulting in Hydrogen Sulfide, which is soluble in water, but as temperature increases, the solubility decreases, which leads to the hydrogen sulfide gas being reinhaled by the animal, causing sulfur induced polioencephalomalacia.

These sulfur springs are often created due to the local volcanic activity which contributes to heating up nearby water systems.

In New Zealand, the North Island was brought to fame in the 1800s, with its baths heated naturally from a volcano near the town of Rotorua.

These methods include The Global Environment Monitoring System for Freshwater (GEMS/Water) has said that typical fresh water holds about 20 mg/litre of sulfur, and can range from 0 to 630 mg/litre in rivers, 2 to 250 mg/litre in lakes and 0 to 230 mg/litre in groundwater.

[9] The US had the Public Health Service in 1970 to measure levels of sulfate in drinking water sources in nine different geographic areas.
