Abstract
A method of remediation at a remediation site having one or more undesirable conditions in which one or more soil characteristics, preferably soil pH and/or elemental concentrations, are measured at a remediation site. A trace element humate surfactant composition is prepared comprising a humate solution, element solution and at least one surfactant. The prepared trace element humate surfactant composition is then dispensed onto the remediation site whereby the trace element humate surfactant composition will reduce the amount of undesirable compounds by promoting growth of native species activity. By promoting native species activity, remediation occurs quickly and environmental impact is minimal.
Claims22
A method for remediation comprising:
- a. measuring one or more organic characteristics of a remediation site, said organic characteristics consisting of at least one characteristic from the group of:
- humic acid concentration, humate salts concentration, fulvic acid concentration, and element concentrations, whereby said remediation site comprises one or more undesirable conditions;
- b. preparing a trace element humate surfactant composition comprising at least one organic characteristic approximately equal in percent concentration to at least one said measured organic characteristic;
- said trace element humate surfactant composition comprising:
- i. a humate solution comprising humic acid, fulvic acid, and humate salts;
- ii. an element solution comprising at least one element from the group of elements consisting of:
- nitrogen, phosphorous, potassium, calcium, magnesium, chlorine, sodium, sulfur, manganese, copper, molybdenum, zinc and iron;
- and
- iii. at least one surfactant;
- and
- c. dispensing said prepared trace element humate surfactant composition onto said remediation site, whereby said trace element humate surfactant composition will reduce the amount of said undesirable conditions at said remediation site which may cause damage by promoting the growth of at least one native species at said remediation site.
A method for remediation comprising:
- a. measuring at least pH of a remediation site, whereby said remediation site comprises one or more undesirable conditions;
- b. preparing a trace element humate surfactant composition comprising at least a pH approximately equal to at least said pH of said remediation site;
- said trace element humate surfactant composition comprising:
- i. a humate solution comprising humic acid, fulvic acid, and humate salts;
- ii. an element solution comprising at least one element from the group of elements consisting of:
- nitrogen, phosphorous, potassium, calcium;
- magnesium, chlorine, sodium, sulfur, manganese, copper, molybdenum, zinc and iron;
- and
- iii. at least one surfactant;
- and
- c. dispensing said prepared trace element humate surfactant composition onto said remediation site, whereby said trace element humate surfactant composition will reduce the amount of said undesirable conditions at said remediation site by promoting the growth of at least one native species at said remediation site.
