Retail fuel distribution releases diesel and gasoline into soil, resulting in petroleum hydrocarbon (PHC)contamination. In cold climate soils, natural attenuation of PHC is limited due to freezing and geologicallimitations. One way to remediate these soils is to stimulate soil organisms to degrade PHC by adding thenecessary nutrients that microbes need to degrade the contaminants. Advances in remediation amendments areurgently needed to improve in-situ biological remediation of hydrocarbons. Hydrochars, a carbon-rich solidmaterial potentially produces a new kind of remediation amendment that can sorb PHC from the soil's solutionand then, as it in term sorbs onto the soil surface, traps it in place for eventual biological degradation.Currently, the synthesis and reactivity of hydrochars as remediation amendments remains untested.The objectives of this CU-I2I proposal are to (a) optimize the synthesis of phosphate-bearing hydrochars (b)evaluate their performance as a remediation material for PHC-contaminated soils in laboratory conditions, (c)conduct field-scale trials of hydrochars on a PHC contaminated site and (d) build a unique College-Universitytraining program for graduate students and College undergraduates.This proposal contains a novel approach that leverages college, university and industrial expertise to create aunique training experience. Students will work with industrial partners and conduct research at sitesundergoing active in-situ remediation. Combining these training goals with our research project will addressesthe industry's need for professional training that explains both the theory and application of in-situ remediation.This CU-I2I will develop not only a remediation technology, but also a unique training pipeline forpractitioners of in-situ remediation.

零售燃料分布将柴油和汽油释放到土壤中，从而导致石油烃（PHC）污染。在寒冷的气候土壤中，由于冻结和地质拟合性，PHC的自然衰减受到限制。补救这些土壤的一种方法是刺激土壤生物来降解PHC，通过添加当时需要降解污染物的必要养分。补救修正案的进展需要改善烃的原位生物修复。氢化体是一种富含碳的固体材料，可能会产生一种新型的修复修正案，可以从土壤的解决方案中进行SORB PHC，然后将其在土壤表面上的术语中，将其捕获到适当的生物学降解。优化含磷酸盐的综合体的合成（b）评估其作为在实验室条件下PHC污染土壤的补救材料的效果Aunique培训经验。学生将与工业合作伙伴合作，并在现场进行现场安排的现场修复。将这些培训目标与我们的研究项目相结合，将解决行业对专业培训的需求，该培训的需求解释了原位补救的理论和应用。这不仅将开发一种补救技术，而且还将开发出独特的培训管道对原位补救的实践者。
