Sulfates, a naturally occurring substance, is commonly found in drinking water sources worldwide. While not considered a primary health threat, concerns have emerged regarding its potential impact on human health. This article aims to delve into these concerns and provide comprehensive insights into sulfate levels in drinking water, their associated health risks, and effective removal methods.
Health Risks Associated with High Sulfate Levels
Diarrhea and Dehydration
Individuals unaccustomed to high sulfate levels in drinking water may experience diarrhea and dehydration. Infants, in particular, are sensitive to sulfates, necessitating sulfate levels below 500 mg/L for infant formula preparation.
Taste and Odor Alterations
Elevated sulfate concentrations can impact water taste and odor, ranging from unpleasant to bitter or medicinal. This alteration in water quality affects drinking experience.
Sulfates in drinking water are regulated by the Secondary Maximum Contaminant Level (SMCL), set at 250 mg/L. Approximately 3% of US public water systems exceed this limit, highlighting the need for heightened awareness.
Major Uses of Sulfate in Industries
Sulfates and sulfuric acid products play pivotal roles across various industries, including fertilizers, chemicals, dyes, glass, paper, soaps, textiles, and more. Notably, aluminum sulfate (alum) is utilized in drinking water treatment, emphasizing its diverse applications.
Environmental Fate of Sulfates
Sulfates enter water through industrial processes like mining, smelting, and paper mills. Solubility varies among sulfate compounds, with some being highly soluble while others, like calcium and barium sulfates, are less so. Sulfur dioxide and sulfur trioxide, byproducts of industrial processes, contribute to sulfate levels in water and air, leading to "acid rain."
Air and Food Sources
Nationwide surveys in the USA record sulfate concentrations in the air, with an estimated daily intake of 0.02-0.63 mg. Sulfates are also present in food, with an average daily intake of around 453 mg, making food a significant source alongside air and water.
Removal of Sulfates: Effective Treatment Systems
To address elevated sulfate levels, several treatment systems are available:
1. Reverse Osmosis
This process, with a 93-99% effectiveness, pushes water through a membrane, removing contaminants, including sulfates.
Boiling water and leaving contaminants behind, distillation removes nearly 100% of sulfates when operated correctly.
3. Anion Exchange
This method, effective for large-scale applications, involves replacing sulfates with sodium or potassium chloride, though it's not commonly used for individual household water treatment.
