This case study of bioaugmentation demonstrates that Petrox bioaugmentation can achieve the very low remediation goals set for pesticides in ground water – quickly and cost effectively.
After three injections of Petrox®, the contaminant concentrations were reduced by 99% in less than 9 months.
Project highlights are:
Source area maximum dieldrin concentrations decreased from 9.8 µg/L to 0.22 µg/L. Concentrations in other source area monitoring wells decreased from 2.7 µg/L to <0.0047 µg/L and 0.12 µg/L to <0.0023 µg/L. The dieldrin remediation goal was 0.002 µg/L.
Source area maximum heptachlor epoxide concentrations were reduced from 0.70 µg/L to <0.0046 µg/L. Concentrations in other source area monitoring wells were reduced from 0.030 µg/L to <0.0046 µg/L and 0.68 µg/L to <0.0095 µg/L. The dieldrin remediation goal was 0.2 µg/L.
Petrox® bioaugmentation was implemented without disrupting property use and without installing injection points inside buildings.
To compare the uptake and translocation of hydrophobic organic chemicals by plant species, the authors performed uptake experiments with β‐1,2,3,4,5,6‐hexachlorocyclohexane (β‐HCH) and 1,2,3,4,10,10‐Hexachloro‐6,7‐epoxy‐1,4,4a,5,6,7,8,8a‐octahydro‐endo‐1,4‐exo‐5,8‐dimethanonaphthalene (dieldrin) using 5 species: Hordeum vulgare, Glycine max, Solanum lycopersicum, Brassica oleracea, and Cucurbita pepo. The present study evaluated uptake ability using root concentration factor (RCF) and translocation ability by...
We investigated selected chlorinated pollutants (β-HCH, γ-HCH, DDDs, DDEs, o,p′-DDT, p,p′-DDT, heptachlor, aldrin, dieldrin, and endrin) in the Lahore and the Sialkot districts of Pakistan, using eggs of cattle egret (Bubulcus ibis) collected during May and June 2007. The pollutant with highest level and frequency was ΣDDT, followed by β-HCH, γ-HCH, heptachlor, aldrin, dieldrin, and endrin in descending order. The concentration(s) were significantly higher in Sialkot...
The sterile insect technique (SIT) is a biological control tactic that is used as a component of area‐wide integrated pest management (AW‐IPM) programs. The SIT can only be applied against disease‐transmitting mosquitoes when only sterile male mosquitoes are released, and the blood‐sucking and potentially disease‐transmitting females are eliminated from the production line. For Anopheles arabiensis, a potent vector of malaria, a genetic sexing strain was developed whereby females can be eliminated by treating the...
The global use of organochlorine pesticides (OCPs) such as Kepone, Lindane, DDT, Dieldrin, Chlordane, and Toxaphene has resulted in long-term soil impacts at many sites. Given the potential risks to human health and the environment, some OCP-impacted sites require treatment. In certain cases, the “dig-and-dump” approach is not practical due to magnitude of the problem, access issues, and/or resource constraints.
Here, “bioremediation” can be used to treat the soil on site, often at lower...
