Sustainable Solid Waste Program: MISSION, VISION, GUIDING PRINCIPALS. MISSION: Provide policy, guidance, and direction to institutionalize and execute sustainable solid resource and waste management practices throughout NRSW for all activities that generate non-hazardous solid waste. Holistic Approach that Emphasizes Resource / Commodity Management Develop Management Approaches for Different Navy Communities. Promote a Culture of Resourcefulness vs. Wastefulness. VISION: By 2012, NRSW will have a fully institutionalized Sustainable Solid Waste Management Program that is efficiently and effectively executed. Move towards SSW s 2020 Vision NOTHING WASTED . GUIDING PRINCIPALS: Use RCRA definition of non-hazardous solid waste and DoD s solid waste hierarchy of: Reduce, Reuse, Recycle, Disposal only as a last resort. Leadership has a role to promote a culture of resourcefulness versus wastefulness.

Field replicate water samples ('field Replicates') collected for the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program during 1992 to 1997 were used to assess the variability of pesticide detections and concentrations in environmental water samples collected from the surface and ground-water-quality networks of the NAWQA Program. Field replicates are two or more identically collected, processed, and analyzed environmental water samples that are used to assess the overall variability of field and laboratory procedures. Variability is the degree of random error in independent measurements of the same quantity and is the opposite of precision-the degree of mutual agreement. Information on variability can be used to estimate the reproducibility of individual measurements, the concentration needed to be assured of exceeding a water-quality standard, and the likelihood that two measurements of water quality are different.

PESP is a voluntary program that fosters partnerships with pesticide users, educators, and related organizations who engage in reducing potential health and environmental risks associated with pests and pesticide use and in implementing pollution prevention strategies. PESP members are organized into one of four groups (according to pesticide use where people Live, Work, Play, and Farm) and progress through three tiered steps (Bronze, Silver, and Gold) to achieve the maximum benefit in the program. PESP members distinguish themselves as stewardship leaders in their respective fields of business and practice.

Sources of PCBs, dioxin, and chlorinated pesticides to Vancouver Lake were investigated during the winter, spring, and fall of 2010 from Burnt Bridge Creek, the Flushing Channel, and two Lake River sites.

The primary habitat management objective for the three refuges of the Willamette Valley NWR Complex is to provide high quality forage for wintering Canada geese. To accomplish this, much of the land within the refuge is managed for grass production involving applications of herbicides, fungicides, and fertilizers. Other agrochemicals such as insecticides are applied to agricultural land outside the refuge. Some agrochemicals used in the area have the potential to enter aquatic habitats of the refuge and could impact species such as amphibians, turtles, or the federally-listed Oregon chub. The objective of this investigation was to sample both biotic and abiotic matrices and use a weight-of-evidence approach to determine if agrochemicals used on or around the refuge pose a risk to aquatic species. This investigation included seven components: 1) evaluation of pesticide use practices; 2) collection of continual water quality measurements; 3) water sampling; 4) in-situ bioassay; 5) analysis of blood plasma from carp and turtles for endocrine-disrupting compound exposure; 6) fish health assessment; and 7) fish tissue analysis for organochlorine pesticides. The components of the study were used as individual lines of evidence to evaluate risk of agrochemicals to aquatic organisms on the refuge. Multiple lines of evidence create more confidence in making decisions suitable for refuge management because the approach considers all the information gathered from the investigation. By framing the assessment with this weight-of-evidence approach, risk to the receptors of concern and organizational levels is more clearly evident and the information can be used in carrying out the Fish and Wildlife Service mission to protect and conserve natural resources.

The landscape, hydrology, and ecology of Lake Wales Ridge, central Florida, are unique in many respects. The Ridge is the highest and most prominent topographic feature in peninsular Florida and contains one of the largest collections of rare and endangered species in the United States (Dobson and others, 1997), one of the highest concentrations of endemic species in North America (Martin, 1998), and more than 200 lakes, most of which are seepage lakes with significant ground-water inflow. Lake Wales Ridge (subsequently referred to as the Ridge) is also one of the most intensely cultivated citrus regions in the world, with citrus groves covering about 25 percent (170 square miles) of the land area. Geologically, the Ridge is underlain by highly permeable marine sands forming relict Miocene-Holocene paleoislands which support some of the oldest ecologic communities in Florida. Ground water and surface water are closely linked in this region where ground-water inflow contributes more than 80 percent of the net water input to some lakes (Sacks and others, 1998). Ground water is the primary drinking-water supply in this region. The unconfined surficial aquifer supplies drinking water for some rural wells, and recharges water to the underlying Upper Floridan aquifer which is the primary municipal water supply.

The Arroyo Colorado is an ancient channel of the Rio Grande River that extends eastward for about 90 miles from near the city of Mission, Texas through southern Hidalgo County to the city of Harlingen in Cameron County, eventually discharging into the Laguna Madre near the Cameron- Willacy County line. The tidal segment of the Arroyo Colorado, as classified by the Texas Commission on Environmental Quality (TCEQ), is between the confluence with Laguna Madre in Cameron/Willacy County to a point 100 meters (110 yards) downstream of Cemetery Road, south of Port Harlingen in Cameron County. This part of the river is also defined as a coastal natural resource area (CNRA) and a coastal wetland in the Coastal Coordination Act. Water quality monitoring over the past decade has confirmed low oxygen levels and escalated ammonia and nitrate concentrations that have contributed to multiple fish kills in the tidal segment. These sub-optimal aquatic conditions resulted in this portion of the Arroyo Colorado being placed on the Texas Water Quality Inventory and 303(d) List for high aquatic life use impairment in 2002. Numerous urban sources, such as point source wastewater discharges, have contributed to this impairment; however, according to the Arroyo Colorado Watershed Protection Plan (ACWPP), nonpoint source agricultural runoff accounts for much of the water quality issues in the tidal segment.

利用OBS-2200车载测试系统,分别在高峰期、平峰期和低峰期的天津市典型路段进行了车载测试,并获得了碳氢化台物(HC)、一氧化碳(CO)和氮氧化物(NOx)等车辆排放的污染物的逐秒数据.结果显示在这3个时段内,车辆的加速度大都集中在-1.5～1.5m/s2,速度大都集中在0～70km/h,并且HC、CO和NOx的最高捧放率为0.0673、0.706和0.0178g/s,都集中在高速(速度(v)＞30km/h,加速度(a)＞0.5m/s2)工况范围内.通过拟合发现,HC、CO和NOx的排放率与比功率(Vehicle Specific Power,简称VSP)之间的拟台决定系数分别为0.71、0.86和0.85,相关性较高,说明VSP可以作为评价车辆排放率的一个重要参考性指标.
