Salt-Water Contamination Information

Benefits of Using In-Situ Amendment Remediation for Salt Water Contamination

• Reduced Overall Cost - 60% to 95% Less Cost

• Minimal Visibility

• Reduced Effect on the Area.

• Reduced Man-power Needs.

• Improved Soil Structure

• Reduced Potential Liability

Salt Water Facts and Basics Rules:

• Cation Exchange Capacity (CEC) – Clay density based on receptor sites.

• Sodium Absorption Ratio (SAR) - A measure of the free salts in the soil

• Exchangeable Sodium Percentage (ESP) – Amount of sodium bound to the clay.

• Water and Time cause free sodium to bind to the soil, sterilizing the soil.

• New spills are easier and cheaper to treat than Historical Spills

• (Almost) Never try to wash salts from the soil, it facilitated sodium binding and rapidly increases sodic contamination.

• Amendment treatments with NaClean or Salt Rx are cumulative.

• Lab Analysis enable tracking of remediation efforts from start to finish.

• Chlorides were removed from the EPA-MCL list in 1997 and reconfirmed in 2003. Chlorides are not a contaminate!

• Chlorides will Flush without Treatment.

• The Sodium from the Salt Water Causes the Damage to the Soil through Cationic Binding.

• Salt Contamination is PROGRESSIVE, AGGRESSIVE and facilitated by Water.

• Sodium Contaminated Soil Remains Sterile until the Sodium is Actively Removed and Replaced

The R & A Process for Salt-Water Remediation

• Mechanically break-up contaminated soils. (Process may be accomplished utilizing a tractor with a disk, tiller, backhoe or Track hoe)

• Add Mulch, Hay, Bagasse, Rice Hulls, Wood Chips or other items to lift and bulk the soil for improved percolation.

• Spray NaClean or Salt Rx in predetermined quantities. (Based on contamination levels or The First Response Chart)

• Flush with Clean Water. (Rain can be used or Irrigation water can be added.)

• Wait from 2 to 12 months to plant grass or other indigenous plants. (Planting time is based on the amount of contamination and the amount of water added to the site after the treatment.)

• Remediation times can be reduced by adding more NaClean or Salt Rx, additional tilling after treatment and regular watering.

• 3 Things effect the speed of NaClean or Salt Rx Remediation:

• The ability of water to pass through the soil – Percolation

• The amount of DeSalt Utilized on the site.

• The amount of water available to the site.

(Adjusting any or all of these 3 items can speed the remediation process.)
