Dust Stop®

Environmentally Friendly Dust Control Solution

Applied Polymer Systems products harness the power of environmentally friendly materials to solve numerous water quality, erosion, and sediment challenges. Anionic polyacrylamide (PAM) is a polymer flocculant that can be used for a wide variety of erosion, sediment, and stormwater management applications. APS products bind, stabilize, and/or remove commonly problematic particles like sediment (clays, silt), metals, and nutrients to prevent erosion, clear water, and improve BMP performance. APS products are made and packaged in the United States, are drinking water quality (NSF/ANSI Standard 60 Certified), have been extensively toxicity tested by third party laboratories in accordance with EPA standards, and are safe for both terrestrial and aquatic organisms and environments.

Product Overview

APS Dust Stop® uses the binding power of polyacrylamide (PAM) to control dust emissions on unpaved roads, job sites, and landfills. This specialized flocculant holds dust and soil in place while preserving water infiltration rates. Made in the USA and approved for use around drinking water supplies, Dust Stop is safe for workers, wildlife, and the surrounding environment.

Directions for Use

Shake well before opening as separation may have occurred.
APS Dust Stop® Emulsions may be applied with hydroseeders, water trucks or other spraying devices. Spraying devices having a mechanical agitator or mixing apparatus or hydraulic recirculation work best.
Pour emulsion into water stream while filling tank or into a filled tank with mixing apparatus running. Allow emulsion to mix for five minutes before application.
APS Dust Stop® Emulsion must be added at the end of the final mix and sprayed immediately. 100% coverage is required for best results (i.e. entire surface has been sprayed/treated).
Caution – Do not exceed 1 gallons of emulsion / 1000 gallons as viscosity of the water may reduce spraying efficiency or damage spraying equipment.

Application Rates

Dust Stop® liquid:

1-5 gallons per acre
Do not exceed 1 gallon Dust Stop /
1,000 gallons of water (in tank)

Precautions / Limitations

Use only as directed – exceeding suggested application rates will not improve performance.
Do not exceed 1 gallon Dust Stop liquid in 1000 gallons of water to prevent clogging hydroseeding or other spray equipment
Clean up spills quickly. Do not use water unless necessary, extremely slippery conditions will result.
Consult manufacturer (Applied Polymer Systems) or authorized distributor for assistance
Lifespan will vary depending on site and environmental conditions, traffic frequency, maintenance

Frequently Asked Questions

Here are some quick answers to common questions about APS polymers, flocculants, and stormwater testing. For more details, visit our full FAQ page.

General Company and Approach

What does Applied Polymer Systems (APS) do?
APS develops and supports polymer-based solutions for erosion and sediment control during construction.

🔗 Learn more about APS
What makes APS different from other erosion control suppliers?
APS focuses on testing, technical support, and correct polymer selection rather than one-size-fits-all products.

🔗 APS technical support approach | Polymer performance testing
Who typically works with APS?
APS works with engineers, contractors, inspectors, and regulators involved in construction-phase stormwater compliance.

🔗 Industries served

Flocculants & Polymers

What are flocculants?
Flocculants help fine sediment particles bind together so they can settle and be captured within BMPs (Best Management Practices).

🔗 Learn more about flocculants
Why are flocculants used in construction stormwater management?
They address fine silts and clays that traditional sediment controls struggle to capture.

🔗 Fine sediment and turbidity control solutions
Do flocculants replace erosion and sediment controls?
No. Flocculants enhance the performance of BMPs, not replace them. They work best in combination with properly designed and maintained basins, ditches, and inlet protection.
What is APAM?
APAM stands for Anionic Polyacrylamide, a polymer flocculant commonly used in construction stormwater applications.

🔗 Anionic PAM overview
Is all APAM the same?
No. Molecular weight and charge density vary, affecting how the polymer interacts with different soils.

🔗 Polymer selection and matching

Why Anionic PAM Is Important

Why does the charge of a flocculant matter?
Polymer charge affects how it interacts with sediments and aquatic life.

🔗 Polymer chemistry and performance
Why is anionic PAM preferred for stormwater applications?
Anionic PAM carries a negative charge that does not readily bind to fish gills or aquatic organisms when used correctly.

🔗 Environmental considerations for polymer use
Why are cationic polymers not used in construction stormwater?
Cationic polymers carry a positive charge and can bind strongly to fish gills, making them unsafe for stormwater applications.

🔗 Proper polymer selection guidance
How does APAM reduce risk to aquatic life?
When properly tested and applied, APAM binds fine sediment particles together so they settle and can be captured within BMPs, reducing turbidity and minimizing interaction with aquatic organisms downstream.
