This Small Business Innovative Research (SBIR) Phase II proposes to develop a Meshless Petrov-Galerkin Geo-Environ Technology For Wide Scale Field Uses. Groundwater supplies are increasingly threatened by organic, inorganic, and radioactive contaminants that are introduced to the environment by improper disposal or accidental releases. Estimates of remediation costs at U.S. government sites alone totals into the billions of dollars. Computational mechanics and aerospace advances in meshless Petrov-Galerkin provide easy means for stable accurate simulations of large groundwater reservoirs without grid generation. The proposed software package Meshless Groundwater Model-Petrov Galerkin (MGM-PG) will be designed for advanced hydrologists as well as for groundwater basin managers, purveyors, and field hydrologists. Current software advancements will be interfaced for easy conceptual model development for various applications.MGM-PG potential market includes: (i) groundwater reservoir quantity and quality management; (ii) cleanup of contaminated sites; (iii) storage of wet year surplus surface water underground and its uses for extended draught periods (ASR projects); (iv) safe disposal of treated effluents by rapid infiltration and extraction projects (RIX projects); (v) conjunctive uses of surface and subsurface water; (vi) landfill sites; and (vii) cleanup of large contaminated Federal Facilities. Proposed technology has applicability to thousands of EPA National Priority List for expedited clean up of contaminated sites and also for groundwater management projects that are implemented at a cost of billions of dollars by federal agencies, State, counties, petroleum facilities, and chemical industries. Worldwide only 4-5 geo-environ codes have been developed for wide variety of societal needs. MGM-PG will be a new technological advancement and will promote training of new graduate students in meshless advances rather than old methods.

这个小企业创新研究（SBIR）第二阶段提出了开发一个无网格的彼得罗夫-伽辽金地质环境技术，用于大规模的现场使用。 地下水供应日益受到有机、无机和放射性污染物的威胁，这些污染物因处置不当或意外释放而进入环境。 据估计，仅美国政府场所的补救费用就高达数十亿美元。 无网格Petrov-Galerkin的计算力学和航空航天进步为大型地下水库的稳定精确模拟提供了简单的方法，而无需网格生成。拟议的软件包无网格地下水模型-彼得罗夫伽辽金（MGM-PG）将设计用于先进的水文学家以及地下水流域管理人员，供应商和外地水文学家。MGM-PG的潜在市场包括：（i）地下水库数量和质量管理;（ii）污染场地的清理;（iii）地下丰水年剩余地表水的储存及其在延长干旱期的使用（ASR项目）;（四）通过快速渗透和提取项目安全处置经处理的废水（RIX项目）;（v）地表水和地下水的联合使用;（vi）垃圾填埋场;（vii）大型受污染联邦设施的清理。所提出的技术适用于数千个EPA国家优先级列表，用于加速清理污染场地，也适用于由联邦机构、州、县、石油设施和化学工业以数十亿美元的成本实施的地下水管理项目。全世界只有4-5个地质环境守则已制定了各种各样的社会需求。MGM-PG将是一项新的技术进步，并将促进新的研究生在无网格的进步，而不是旧的方法的培训。
