Sulfate is of concern because wastewater from various industries often contains a lot of sulfate, which could then makes its way
into nearby water bodies and then into nearby soil. In 1973 the Minnesota Pollution Control Agency set a limit for discharge water sulfate levels to protect the health of the environment. Which of Minnesota's staples is MOST vulnerable to sulfate levels?
Answer: The Minnesota Pollution Control Agency is reviewing its standards for protecting wild rice in Minnesota. With funding from the Minnesota State Legislature, the agency conducted a two-year study to determine how sulfate—the presence of which in water has been linked to an absence of wild rice—and other chemicals affect the health of wild rice.
