There are a few different contaminants or pollutants that may impact stormwater runoff and related areas for construction sites, and one of the most well-known here is sediment. Often caused by erosion from soil, the presence of sediment in stormwater can be a significant pollutant that must be managed properly on the job site.

At Cearley SWPPP, we're here to help with all stormwater pollution prevention needs in Ogden and nearby areas, from plan creation and permits to inspections, training, signage and more. Here are some basics on what sediment is, the sources it can come from, and why it's a pollutant risk on sites - plus what should be done to control it.

What is Sediment?

For those unfamiliar with the term, sediment is simply particles of sand, silt, clay and organic material (such as leaves) that become suspended in water. It can come from a variety of sources, including:

The Risks Posed by Sediment in Water

There are several ways sediment in waterways can degrade the quality of water and create pollutant and contaminant risks. These include:

Carrying Other Pollutants

Maybe worst of all, sediment often carries other significant pollutants along with it as it flows through water. Here are some examples:

Therefore, managing sediment on job sites is essential to protecting the environment, preventing pollution and minimizing potential costs associated with cleanup.

How to Consider Sediment Within SWPPP

Sediment control is a big part of any stormwater pollution prevention plan. It is important to include strategies for sediment control in your SWPPP, particularly if you are working on a job site that has potential for increased erosion or discharge of sediment into receiving waters.

Your SWPPP should include methods and practices for preventing the generation of sediment before it is released off-site, as well as measures for controlling sediment that is already on the job site. These can include things like silt fences, check dams and other best management practices (BMPs) designed to reduce and control sediment.

You should also consider how to prevent erosion from occurring in the first place. This can include slope stabilization practices, using terracing or vegetation, and other methods to reduce the chance of erosion in high-hazard areas. Additionally, consider how you will manage sediment after it is created, such as using catch basin inserts or sandbags for drainage systems.

At Cearley SWPPP, we have a team of stormwater experts who can help you to consider sediment in your SWPPP, so that you can protect the environment and maintain compliance with regulations. Contact us today to learn more about any of our SWPPP services around Ogden.
