Problems

Total Dissolved Solids

Total dissolved solids (TDS) indicate the amount of ions, including salts and metals, dissolved in a certain amount of water. Some dissolved ions in water are common, such as some CO 2 from respiration by organisms, or salts in saltwater. However, above certain levels, TDS can be detrimental to ecosystems. Anthropogenic sources of high TDS are common, and include agricultural/pesticide runoff, sewage discharge, or increased salinity from de-icing salts.

The implications of TDS can be extremely difficult to explore, as the measurement does not differentiate between the different ions dissolved in water. Some ions may be beneficial, like nutrients, while some may be deleterious, like metals. Each type of substance can have a different effect on the physiology of the organisms in the environment.

The best way to lower the TDS level of your local creeks or rivers is by prevention.

  • Adopt

  • Allow for natural growth near waterways

    If you live or work next to a waterway, leave a 35′ to 100′ no mow zone on its banks. Allow natural and native plant growth in this buffer area or plant native trees, bushes, and groundcover. This vegetation can filter pollutants before they reach your waterway and provide other water quality benefits that far exceed those of a mowed lawn. Native plants and grasses require less watering and fertilizer and also provide important habitat for native species of wildlife.

    Resources include:

  • Plant a rain garden

    Rain gardens can filter and infiltrate stormwater that flows across your yard.

    Resources include:

  • Reduce paved, impervious surfaces

    Impervious or impermeable surfaces, like pavement, contribute significantly to polluted stormwater runoff and alter stream flow habitat. If you’ve got excess pavement you’d like removed, consider a de-paving project with the Compact. Elsewhere, ensure that your downspouts drain to vegetation, gravel, or rainbarrels, rather than impervious surfaces. If you constructing or repairing your driveway, pervious pavement allows stormwater to infiltrate and filter through the ground. If you can’t do the whole drive, consider making only the portion closest to the street pervious.

  • Employ agricultural best management practices.

    Excluding farm animals from this waterway and providing them with alternative sources of water can prevent animals from trampling streamside vegetation and defecating in the waterway.

    Resources include:

  • Limit fertilizers and pesticide use

    Fertilizers, pesticides and other pollutants can attach themselves to soil particles and find their way to your creek.

    • How to Soil Sample a Lawn or Garden – UT Extension
    • Principles of Home Landscape Fertilization – UT Extension
    • Nutrient Outreach and Educational Materials – EPA
    • UT Municipal Technical Advisory Service provides a number of related educational resources including Lawn and Garden Fertilizers, Lawn Watering, and Managing Leaves and Yard Trimmings.
  • Support public funding of water treatment plants and sewer infrastructure.

    Water related infrastructure is expensive and obtaining funding for necessary sewer and water treatment improvements is often a challenge for communities. However, public dollars are critical to our water quality and public health. Support your community’s efforts to properly maintain it’s water related infrastructure.

    Resources include:

    • America’s Infrastructure Report Card – American Society of Civil Engineers
    • How Sewage Pollution Ends Up in Rivers – American Rivers
    • Greening Water Infrastructure – American Rivers
  • Organize with others in your community. Make your voices heard and your votes count.

    Participate in community planning efforts and advocate for relevant measures that improve or protect water quality. Write to your elected official and let them know this is concern or invite them to speak about the impairment with your home-owners association. When elections come up, vote for candidates who will address the problem and hold them accountable to their promises. Support local watershed / environmental associations.

    Resources include:

  • Spread the word.

    Do your neighbors, family, or roommates know about the problem? Now that you know how to be an effective steward, enlist the help of others in your neighborhood. Share iCreek or resources within it with your neighbors and encourage them to join the effort to protect your creek.

  • Use nontoxic deicing methods.

    Deicing can be extremely detrimental to aquatic ecosystems. Make use of non-toxic options where possible. Encourage those responsible for significant deicing activity in your community to consider non-toxic or less toxic options.
