Environmental Services Program
Protecting Our Water
The Water Quality Monitoring Section is responsible for assessing the biological health of Missouri’s rivers and streams, and monitoring water and sediment quality throughout the state. The section includes the aquatic biological assessment and water monitoring units. The section works in support of the Water Protection Program to ensure that Missourians will always have clean water for drinking, recreation, tourism and continued economic growth. Staff travel to all areas of the state conducting a variety of investigations. These investigations routinely include wastewater discharge monitoring, groundwater monitoring, electrofishing and stream surveys. The section often assists with special projects such as enforcement actions, environmental risk assessments or damage assessments resulting from chemical spills. The staff collects and evaluates a wide variety of water, sediment and macroinvertebrate samples. The results of these studies are used to make certain that the rivers, streams and lakes of Missouri remain a treasure for all to enjoy.
Aquatic biological assessments are evaluations of the conditions of water bodies using surveys and other direct measurements of residential biological organisms, such as macroinvertebrates, fish and plants. Biological assessment results are used to answer the question of whether water bodies support the survival and reproduction of desirable fish, shellfish and other aquatic species.
Missouri State Parks Swimming Area E. coli Sampling and Results
The Water Quality Monitoring Unit provided weekly E.coli analysis of water samples collected from 20 swimming areas located in the department’s state parks during the recreational season. Staff completed more than 580 analyses.
Lake of the Ozarks E. coli Sampling
The Water Quality Monitoring Unit, working with volunteers from the Lake Ozark Watershed Alliance, collected E. coli samples from 118 coves throughout the lake starting in 2007 and ending in 2011. The unit analyzed 1619 samples collected during the study. Then annual geometric means for the survey ranged from 3.0 to 8.8 colonies per 100 milliliters of water.
