Knowing the health of Missouri’s water helps the department take the correct measures to protect and keep our water clean for everyone’s use. Department staff and trained volunteers take samples of Missouri’s streams, lakes and rivers to gauge the overall health of the water. The samples are analyzed in the department’s laboratory to ensure the safety and quality of these precious resources.
