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.

零售燃料分销将柴油和汽油释放到土壤中，导致石油烃污染。在寒冷的气候土壤中，由于冻结和地质限制，PHC的自然衰减是有限的。修复这些土壤的一种方法是通过添加微生物降解污染物所需的必要营养素来刺激土壤生物降解PHC。迫切需要在修复修正方面取得进展，以改善碳氢化合物的原位生物修复。碳氢化合物是一种富含碳的固体材料，它可能产生一种新的修复改良剂，可以从土壤溶液中吸附PHC，然后，当它长期吸附到土壤表面时，将其捕获到位，最终进行生物降解。作为补救改良剂的氢焦的合成和反应性仍然未经测试。本CU-I2 I提案的目标是（a）优化含磷酸盐氢焦的合成（B）在实验室条件下评估它们作为PHC污染土壤修复材料的性能，（c）在PHC污染场地上进行水炭的现场试验，（d）为研究生和大学本科生建立一个独特的大学培训计划。学生将与工业合作伙伴合作，并在现场进行积极的原位修复研究。将这些培训目标与我们的研究项目相结合，将满足行业对解释原位修复理论和应用的专业培训的需求。该CU-I2 I不仅将开发修复技术，还将为原位修复从业者提供独特的培训管道。
