Bioremediation...“...microorganisms naturally present in the soils were actively consuming fuel-derived toxic compounds and transforming them into harmless carbon dioxide...the rate of these biotransformations could be greatly increased by the addition of nutrients...to increase rates of biodegradation and thereby shield the residential area from further contamination.”...“...cleaning up pollution by enhancing the same biodegradation processes that occur in nature...treating the contamination in place so that large quantities of soil, sediment, or water do not have to be dugup or pumped out of the ground for treatment.”...
...Replant New Orleans will use the application of compost, compost tea made from worm castings...provide mechanisms for neutralizing toxins and stimulates the production of natural bacteria in the soil that will combat toxic materials...provide community garden space for the large scale production of compost and compost tea, as well as provide space for growing phytoremediation plants...“compost improves soil texture and structure, qualities that enable soil to retain nutrients, moisture, and air for the support of healthy crops...helps control erosion..the best recycler of biological wastes, turning millions of tons of our refuse into a food-growing asset...provides and releases plant nutrients, protects against drought, controls pH, supports essential bacteria, feeds helpful earthworms...acts as a buffer against toxins in the soil...conserves a nation’s nonrenewable energy resources.”......Compost tea is a liquid solution made by extracting beneficial microbes from compost and/or worm castings...combats disease-causing microbes, degrades toxic materials, produces plant growth hormones,mineralizes available nutrients in the soil, fixes nitrogen, and prevents pathogens from infecting plants. Phytoremediation...“...is the use of specialized plants to clean up polluted soil. While most plants exposed to high levels of soil toxins will be injured or die,...certain plants are resistant, and an even smaller group actually thrive. The thriving plants show a particular potential for remediation because...some of them actually transport and accumulate extremely high levels of soil pollutants within their bodies...hyper-accumulators....are being used throughout the country to help cleanup heavy metal polluted soil. Heavy metals are some of the most stubborn soil pollutants. They can bond very tightly to soil particles, and they cannot be broken down by microbial processes. Most heavy metals are also essential plant nutrients, so plants have the ability to take up the metals and transport them throughout their bodies. However, on polluted soil, the levels of heavy metals are often hundreds of times greater than normal, and this overexposure is toxic to the vast majority of plants. Hyper-accumulators, on the other hand, actually prefer these high concentrations...acting as natural vacuum cleaners, sucking pollutants out of the soil and depositing them in their above ground leaves and shoots. Removing the metals is as simple as pruning or cutting the hyper-accumulators above ground mass, not excavating tons of soil. ”Sunflowers are one such hyper-accumulator, and are therefore an important component in Replant New Orleans’ plan for bioremediation. They are easy to obtain and distribute, are native to the entire United States, and make a beautiful contribution to New Orleans. These plants take heavy metals, such as lead out of soil...
