Sulfate in Water Test Strips 0, 250, >500 ppm (481200) 30 Test Strips, Result in 30 Seconds

The sulfate test can be used to quickly determine the sulfate content of drinking water, industrial waste (from galvanizing and leather industry), and wastewater. The US EPA Secondary Drinking Water Standard is 250 mg/L (ppm). The dip-and-read strip is decolorized by sulfate.

0, 250, >500 ppm (mg/l)

Water containing high levels of sulfates, particularly magnesium sulfate (Epsom salts) and sodium sulfate (Glauber's salt) may have a laxative effect on persons unaccustomed to the water. These effects vary with the person and appear to last only until one becomes accustomed to using the water. High sulfate content also affects the taste of water and will form a hard scale in boilers and heat exchangers. For these reasons the upper recommended limit for sulfates is 250 mg/L.
