The most frequently encountered forms of sulfur in fresh waters are as the anion sulfate (SO4-2) in combination with the common cations and as hydrogen sulfide (H2S). The thresholds of taste and smell were reported to be 0.2mg/L of sulfides in pulp mill wastes. Sulfate is not highly soluble.
The Advisory discusses the limitations of the current database for estimating a risk level for sulfate in drinking water and characterizes the hazards associated with exposure.
Sulfate is a common water contaminant that can have a significant impact on water quality and health. High levels of sulfate in water can lead to a variety of health effects, including potential impacts on gastrointestinal health and the risk of developing kidney damage.
Sulfate was found to be present in 645 of 658 groundwater supplies and in all of the 106 surface water supplies sampled. Sulfate levels ranged from <1 to 770 mg/litre, with a median of 4.6 mg/litre. Only 3% of the water supplies sampled had sulfate levels in excess of 250 mg/litre (US EPA, 1999a).

Sulfate is a group of mineral salts that can occur naturally in groundwater and can affect the quality of well water in several ways. It is important to note that sulfate itself is not considered harmful to human health at typical levels found in drinking water.
12 Ιουν 2019 · High concentrations of sulphates can cause water to have an unpleasant taste, while low concentrations of calcium and magnesium sulphate are reported by the World Health Organisation to improve the taste of drinking water.1.
