Grou ndwater samples co11 ected from shallow, private wells; su boreholes; and boreholes drilled from the 330 m and 410 m mine levels were analyzed for their major ion chemistry, dissolved gases, and environmental isotope conterits. The principal change in the chemical load with depth is typified by chloride concentration, which increases from less than 5 mg/liter to about 300 my/liter. There is a parallel increase in pH, which changes from about 6.5 to over 9.75. It is important to notice that calcite saturation is maintained and that, because of rising pH, dissolved inorganic carbon is lost. The total carbonate content thus decreases from about 70 mg/liter to less than 7 mg/liter. The 180 and deuterium analyses demonstrate that different fracture systems contain different water masses, whose age increases with depth. Groundwater age determinations with 14C and isotopes of the uranium decay series strongly indicate that water ages exceed 25,000 years. The 13C contents of the aqueous carbonate in these groundwaters indicate groundwater recharge through vegetated soil--presumably during an interglacial period. The 13C and 180 determinations show that most fracture calcites have formed in a wide variety of depositional environments~ and not in the waters circulating today.","PeriodicalId":17982,"journal":{"name":"Lawrence Berkeley National Laboratory","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72549384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This project took a life cycle approach to comparing tank and tankless water heaters in Northern and Southern California. Information about the life cycle phases was calculated using the European Union�s Methodology study for EcoDesign of Energy-using Products (MEEUP) and the National Renewable Energy Laboratory�s Life Cycle Inventory (NREL LCI) database. In a unit-to-unit comparison, it was found that tankless water heaters would lessen impacts of water heating by reducing annual energy use by 2800 MJ/year (16% compared to tank), and reducing global warming emissions by 175 kg CO2 eqv./year (18% reduction). Overall, the production and combustion of natural gas in the use phase had the largest impact. Total waste, VOCs, PAHs, particulate matter, and heavy-metals-to-air categories were also affected relatively strongly by manufacturing processes. It was estimated that tankless water heater users would have to use 10 more gallons of hot water a day (an increased usage of approximately 20%) to have the same impact as tank water heaters. The project results suggest that if a higher percentage of Californians used tankless water heaters, environmental impacts caused by water heating would be smaller.","PeriodicalId":17982,"journal":{"name":"Lawrence Berkeley National Laboratory","volume":"2017 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85778722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Daley","doi":"10.2172/1016704","DOIUrl":"https://doi.org/10.2172/1016704","url":null,"abstract":"Executive Summary LBNL’s recent analysis of the microseismic data being acquired at well KB‐601 has produced a new result of significantly more microseismic activity than previously estimated. During 2009‐2010, there was background activity of 1 or 2 events per day with a notable increase during the spring‐summer months of up to 20 or more events in a signal day (Figure 1). This level of activity warrants increased effort to obtain quantitative information, and supports plans for expansion of the microseismic monitoring. Quantitative interpretation of these events, including locations, is still hampered by physically unrealistic data from some sensors and uncertainty in which sensors are being recorded and their depth. We now believe that some quantitative analysis will be possible, building upon LBNL’s earlier work and analysis conducted by Pinnacle, and utilizing the sledge‐hammer tests conducted in the fall of 2010 by the JIP. Current acquisition problems include electrical noise, lack of GPS clock timing, and the sensor uncertainty. To address the acquisition problems, we continue to recommend an active‐source recording test with full 144 channel capability (or at least 48 channel). We also recommend a site visit for debugging and repair by a t echnician knowledgeable in the REF TEK recording system and microseismic a cquisition. Detection of Events We have developed an event detection processing flow which has been successful in identifying more events than previous reports. We also have now applied this processing to the entire 2009‐2010 data set. An important assumption in this processing and analysis is that the non‐physical data seen on 3 of the 6 recorded geophones is due to equipment problems or incorrect wiring of the geophones. Since the uphole wiring has been checked, it seems likely that there are downhole wiring problems. We are now using only two geophones (from one of the three REF TEK data recorders) to identify seismic events. Additionally, we are using a spike removal algorithm along with a time‐shifting algorithm (as first applied by Pinnacle) and an automatic event detection algorithm. Spike removal is necessary because of numerous noise spikes presumably electrical in nature. Time shifting (utilizing the electrical noise spikes) is necessary because the recording systems are not receiving GPS clock signals and are therefore drifting in time.
