Saltwater Damage & Sodic Soil Remediation
Salt contamination of soils is a serious environmental issue facing the oil and gas industry today. Sodic Soil or saltwater damage from produced water spills and leaks can completely devastate surrounding vegetation. As the accumulated sodium reaches higher concentration levels, the plants normal transpiration processes (absorption of water from the soil) are affected. As sodium concentrations increase, water that previously flowed easily into the
plants root system is reduced. Until recently the remediation of sodium affected soils has been a time consuming, ineffective and expensive process. Newly developed technology offers a fast, easy and cost-effective way to salt water soil remediation.
Sodium affected soils have poor physical properties and commonly have crusted surfaces which prevent water percolation, causing runoff and erosion. Remediation of sodium damaged soils in a timely manner necessitates replacing the exchangeable sodium with a stronger and more favorable cationic source. Research and experience have shown that the sodium (Na+) levels in the soil structure can be reduced through electrolyte manipulation, replacing the damaging sodium with more desirable minerals.
In the past gypsum, lime or calcium nitrate have been used to attempt to accomplish this, however with poor results. The low solubility of gypsum, lime or the negative environmental impact of nitrates makes these poor and costly choices. Now, with chemistry developed through a joint effort between the Chemical, Agricultural and Petroleum Industries, salt water damaged soils can be effectively remediated. DeSalt Plus™ is a stable amendment containing stabilized Calcium, Ammonium, Potassium cations with immediate and 100% availability plus special surfactants that allow the salt contamination to be flushed away.
Salt water damaged sites can be restored.
Treating Sodium Damaged Soils
The most common procedure for correcting sodium affected soils is to amend the soil with materials that replace the exchangeable sodium on the soil colloids. Remediating sodium damaged soils in a timely manner requires lowering the exchangeable sodium percentage (ESP) with a stronger more favorable cationic sources. The result is the displacement of the sodium ions in the soil, which are then free to be flushed out of the growth zone.
DeSalt Plus™ was specifically developed for treatment of severely sodium damaged soils. It quickly displaces and removes sodium from the soil, restoring the soil to a natural growing condition.
DeSalt Plus™ is a stabilized amendment containing Calcium, Ammonium, and Potassium cat ions with immediate, 100% availability. DeSalt Plus™ also contains Geo Rinse™™ percolation and flushing agent that allow the salt contamination to be flushed away.
In sodium affected areas, nutrients are often stripped from the soil depriving plants of the proper nutrition for growth. Once the sodium has been treated and removed from the soil, proper plant nutrients are required for plant recovery and re-growth. DeSalt Plus™ removes the sodium plus increases the nutrient uptake of the plant improving plant structure and new growth.
Jump Start™ is a specially designed pre-emergent growth stimulator and nutrient supplement for accelerated germination of crops and vegetation in areas previously affected by salt and hydrocarbon contamination. Jump Start™ stimulates growth while supplying a stabilized balance of vital nutrients for depleted and stressed soils. Soils affected by salts and hydrocarbons are usually deprived of the soil structure and critical nutrients necessary for seed emergence and re-growth. Jump Start™ also strengthens cell wall structure for improved development during plant emergence.
GeoRinse™ is a surfactant pre-mix solution for use in remediation of saltwater contaminated soils. GeoRinse™ improves percolation and soil contact when added to irrigation water or dilutions of DeSalt Plus™ or Jump Start™
The principal carrier of salt through our environment is water. In the oil and process industries, salt laden waters are stored and transported via cross country piping and storage networks. These systems, through leaks and spills, cause accidental influxes of salt to the soil that can completely devastate all vegetation and stop biological activity in a matter of days.
