"This study develops, evaluates, and optimizes the potential of a novel "counter-diffusional?membrane biofilm reactor to biologically treat and remove trichloroethylene (TCE) from contaminatedsoil and groundwater caused by industrial activities (industrial solvent). The objectives of the researchare to investigate and evaluate design and operational factors reflecting the sustainability anddegradation rates of TCE transformation in a counter-diffusional membrane-attached methanotrophicbiofilm reactor systemAs a first step attaining this objective, an overall mass transfer coeficient of the bioreactor wasdeveloped a 23 laboratory experimental design have already conducted, and the development of amathematical model and computer simulation describing the concentration profile of substrates and TCEwithin the biofilm has been introducedA maximum sustainable TCE removal j7|o: of 205 Elmo!/m7/day was successfully attained when theCH,¢ utilization rate was 11.67 mmoles/m2/hr, the TCE loading rate was approximately 400 mol/m2/day.Normal probability plot and pareto chart indicated that methane partial pressure (P) and hydraulicReynolds 's numbers (Re) have important and significant positive effects on the TCE degradation rates.The average percentage of TCE removal eficiency falls between 78.6 and 94. 7%."

"This book provides the reader with the comprehensive view necessary to understand and critically evaluate the design, implementation, and monitoring of phytoremediation at sites characterized by contaminated groundwater. Part I presents the historical foundation of the interaction between plants and groundwater, introduces fundamental groundwater concepts for plant physiologists, and introduces basic plant physiology for hydrogeologists. Part II presents information on how to assess, design, implement, and monitor phytoremediation projects for hydrologic control. Part III presents how plants take up and detoxify a wide range of organic xenobiotics in contaminated groundwater systems, and provides various approaches on how this can be assessed and monitored.

"This textbook employs a technical and quantitative approach to explain subsurface hydrology and hydrogeology, and to offer a comprehensive overview of groundwater-related topics such as flow in porous media, aquifer characterization, contaminant description and transport, risk assessment, and groundwater remediation. It describes the characterization of subsurface flow of pristine and polluted water and provides readers with easily applicable tools for the design of water supply systems, drinking-water source protection, and remediation interventions. Specific applications range from groundwater exploitation as a drinking water supply to the remediation of contaminated aquifers, from the definition and safeguarding of drinking-water sources to the assessment of human health risks in connection with groundwater contamination events.The book represents an ideal learning resource for upper-undergraduate and graduate students of civil engineering, environmental engineering, and geology, as well as practitioners in the fields of water resource management and environmental protection who are interested in groundwater engineering and technical hydrogeology."

"ABSTRAKThe increasing demand of raw water in DKI Jakarta has caused excessive groundwater abstraction. It causes the groundwater level drop to certain level and has emerged cone of depression in some areas. Groundwater management as an effort to recover the groundwater level, requires an integrated groundwater monitoring system. Recently, there are approximately 161 groundwater monitoring wells in Jakarta groundwater basin. Those wells are generally categorized as secondary network, since determined by groundwater abstraction activity. Meanwhile, a representative primary network to monitor the natural condition of groundwater in each aquifer layer is not yet available completely. The method of Inverse Distance Weighting (IDW) spatial estimation is applied to determine the number and distribution of primary monitoring wells based on aquifer geometry using Groundwater Modeling System (GMS) software. Based on the aquifer geometry, it can be arranged monitoring zones and the number of monitoring wells in each zone. There are 9 monitoring zones in Jakarta groundwater basin consist of 1 zone with 1 monitoring well, 2 zones with 2 monitoring wells, 3 zones with 3 monitoring wells, and 3 zones with 4 monitoring wells, so that the total of primary monitoring wells for groundwater monitoring in Jakarta groundwater basin is 26 monitoring wells. This research is expected to be useful for stakeholders to optimize the representative monitoring wells network based on aquifer geometry in sustainable groundwater management. "

"Air tanah yang memiliki kualitas baik terbentuk dalam jangka waktu yang cukup lama den berbanding terbalik dengan jangka waktu pengambilan yang dilakukan oleh manusia. Untuk menghindari timbulnya permasalahan baru, diperlukan suatu simulator yang dapat mensimulasi gerak aliran air tanah pada suatu daerah sehingga dapat diprediksi dampak pengambilan air tersebut.

Groundwater that has a good quality is formed in long time period inversely propotional to groundwater taken by humans. To avoid the emergence of new problems, we need a simulator that can simulate the movement of groundwater flow in a region that can predict the impact of taking water. This thesis is developing a groundwater flow model in two dimensions by using a simple platform and solution, temporal solution of numerical method Runge-Kutta 4th Order, to be an alternative simulator of groundwater flow that is needed."
