Since our city’s founding, Memphis has served as a major port city due to its convenient location on the shore of the mighty Mississippi River. What many people may not realize is that Memphis and the entire Mid-South region have several other waterways throughout our land. Another surprising fact is that all rivers in West Tennessee are classified as impaired due to siltation. Siltation, also known as sediment pollution, is caused by natural activities like erosion and sedimentation, but most often, is a result of human activities, such as agriculture, construction and heavy industrial processes. Construction activities have the largest impact on siltation of our streams. As development occurs, these streams often need protection and regular monitoring.


Siltation has several harmful effects on the natural environment. Soil erosion and sediment spills can lead to accumulation in the bottom of waterways. This concentration of sediments can affect water flow, pollute natural habitats and harm aquatic life. Humans also depend on clean water from these streams for farming or industrial facilities. Additionally, accumulation can affect navigation channels and slow down boats and large vessels traveling through.

Tioga’s environmental scientists and engineers prepare erosion prevention and sediment control permits and stormwater pollution prevention plans for construction and industrial activities. Typically, these documents are required for construction projects that disturb more than one acre of land. We also conduct regular inspections to prevent prolonged stream siltation. These plans and inspections minimize the amount of additional solids entering and accumulating in our local streams and larger connecting bodies of water.

If your property is affected by siltation or if you have a construction project requiring a SWPPP, please contact our experts today.
