Water Quality

Understanding and Improving Water Quality

It's all about clean water!

Water quality is at the heart of what MSD does every day, as our mission is to protect public health and the environment by collecting, treating, and managing wastewater.

We have monitored water quality (for chemical data) in the Mill Creek, Little Miami, Great Miami, and Ohio rivers since 1998, and since 2011 have been conducting comprehensive water quality and aquatic habitat studies.

MSD Water Quality Studies

MSD is currently partnering with the Midwest Biodiversity Institute to monitor water quality and aquatic habitat in the Mill Creek, Little Miami, Great Miami and Ohio rivers and their tributaries through comprehensive biological, chemical, and physical sampling and analysis.

The work began in 2011-2014 with a benchmarking study in each river and is continuing in 2016-2019 with follow-up studies.

The focus of the studies are to:

  • Compare water quality and aquatic habitat (e.g., fish and macroinvertebrates) in each river to the baseline data to gauge improvement.
  • Mill Creek sampling
  • Identify stressors (e.g., pollutants) to water quality and aquatic habitat
  • Identify the overall health of each aquatic system, as indicated by attainment of Ohio EPA water quality standards
  • Use the data - via MSD's Intergrated Prioritization System (IPS) - to help prioritize Capital Improvements Projects to improve water quality and aquatic habitat in each of these waterways.

2018 Water Quality Forum

MSD hosted a public Water Quality Forum in late 2018 to provide an update on our efforts to track and assess local water quality. The good news is that water quality in our local streams, including the Mill Creek, is steadily improving!

Here's a summary of recent water quality findings:

  • Mill Creek - lower portion (modified warmwater habitat): Full attainment, continues to improve
  • Mill Creek - upper portion (warmwater habitat): Partial attainment, continues to improve
  • Little Miami (exceptional warmwater habitat) - Full attainment, but inconsistent improvement trends
  • Duck Creek (limited resource, modified warmwater habitat and warmwater habitat) - Partial attainment, improving
