Field Sampling. Provide additional production material to allow freshly mixed elastomeric concrete to be sampled for acceptance. A minimum of six 2 inch cube molds and three 3x6 inch cylinders will be taken by the Department for each day’s production. Compression, splitting tensile, and durometer hardness testing will be performed by the Department to determine acceptance. Materials failing to meet the requirements listed above are subject to removal and replacement at no cost to the Department.

Field Sampling. ACE agrees to field sample effluent samples for PH, Temperature, DO, Turbidity and Chlorine Residual. All meters to be in good working order and calibrated per manufactures requirements.
Field Sampling. Humpback Chub sampling in Westwater Canyon occurred in September and October of 2011 and 2012. Three eight-day sampling passes were conducted each year. Approximately six days elapsed between the end of one pass and the beginning of the subsequent pass in 2011, and approximately seven days elapsed between passes in 2012. During each pass, Miners Cabin, Upper Cougar Bar, and Lower Cougar Bar (Figure 1) were sampled for two nights and Hades Bar was sampled for one night. The Hades Bar site was not sampled on the third sampling trip of 2011 and 2012. This was due to motor issues and inclement weather. Multi-filament xxxxxxx nets (23 m x 2 m; 2.5 cm mesh) and a motorized/oar electrofishing (ETS Electrofishing) Cataraft were used to collect fish. Hoop nets were utilized intermittently in 2003 and 2004, but were not used during sampling in 2007–2012. Xxxxxxx nets were set in mid-afternoon and checked every 1.5-2 hours until approximately midnight, at which time they were pulled. Nets were reset before sunrise and allowed to fish until approximately noon, while being checked at similar time intervals as evening sets. Xxxxxxx nets were set to target adult Humpback Chub in deep eddies off boulder or rock faces. Nets were occasionally also set in shallow xxxxxx/run habitat. All chub were removed from the net, processed in camp, and released. Due to this protocol, a few chub were recaptured during the same 18-hour sampling period. Electrofishing was conducted during each pass in 2011 and 2012. In 2003 and 2004, only a single electrofishing pass was conducted. Single pass electrofishing was previously established under the ISMP protocol. Increased electrofishing was conducted beginning in 2005 to increase the catch of juvenile and sub-adult chubs and strengthen population estimates. The majority of electrofishing occurred at the three upstream-most sites. Electrofishing effort was limited at Hades Bar because of the short sampling distance (0.2 river miles). Shoreline habitats were electrofished within each site. Electrofishing occurred prior to xxxxxxx nets being set and subsequent to nets being pulled. All adult Humpback Chub and Roundtail Chub collected during electrofishing were used in their respective population estimates. Electrofishing data were also used in determining catch rates, length-frequency analysis, and movement of chub in Westwater Canyon. Chub were identified to species using a suite of diagnostic qualitative characters (i.e., degree of frontal dep...
Field Sampling. NASA will provide Native American and archeological monitors to accompany field sampling of soil within Burro Flats Site and buffer area defined by NASA in 2008 for management purposes; or any other known archeological sites and will endeavor to coordinate any sampling within Burro Flats Site Boundary with the boundary determination work, if feasible.
Field Sampling. The study was conducted during the first rainy season peak in July 2012. Water samples were collected over a two-day period, July 9th and July 10th. Using Amber borosilicate glass containers with PTFE-lined tops, a total of 8 samples were collected from the Solous I site and 6 samples from the Olushosun site. Samples were collected from xxxxx and boreholes in labeled vials and the temperature of the water samples was recorded on site using a thermometer. Solous I samples were labeled S1- S8 and Olushosun samples were labeled O1-O6. In addition, the GPS coordinate of each sampling point was recorded as well as the distance from the dumpsite. Samples were then stored in a refrigerator at 4°C for a maximum of 10 days until analysis.
Field Sampling. Purple Xxxxxx nests will be monitored for activity and 1 egg will be removed from each of up to 10 nests per colony. Eggs will immediately be placed in well-padded, labeled polyethylene bags, and stored in fiber eggs cartons in a cooler on wet ice until return to the laboratory. Once in the laboratory, eggs will be stored in a refrigerator until dissection within 30 days of sampling. Lab Processing Once transferred to the lab each egg will be measured prior to dissection. The contents of each egg will be removed remove and examined for viability, incubation stage, and malformations of any embryos. Each egg sample will be dried and homogenized to a fine powder in an analytical mill. Dried samples will be stored in dark desiccators until analysis. Mercury Determination Each sample will be analyzed for total mercury concentration at the USGS Pacific Northwest Environmental Mercury Laboratory in Corvallis, Oregon. Mercury will be determined via thermal decomposition coupled with atomic absorption spectroscopy, following EPA method 7473. Prior to analysis, the equipment will be calibrated using NIST-certified standard solutions.

Field Sampling. ACTIVITY Field sampling activities discussed in this section pertain to the Phase I RI, which will focus on identifying potential source areas, delineating the extent of soil and groundwater contamination at the East Xxxx site, and attempting to determine whether additional source areas are contributing to contamination at the East Xxxx site. Phase I will also evaluate the potential for impacts to surface water and sediment in the Great Miami River and evaluate the possible nature and extent of contamination in indoor air of structures within the area of the groundwater contaminant plume. As previously discussed, the sub-slab monitoring and indoor air sampling locations and methodologies, some of which are yet to be determined, will be presented in an addendum to this SAP. For this reason, subsequent discussions in this SAP focus on the other activities (soil, groundwater, surface water, and sediment sampling and related activities) that will be completed during Phase I of the RI. Figures 5-8 show the locations of proposed Phase I sampling and investigation activities. Table 6 lists all samples to be collected, the number of samples, and specific information on collection. A detailed discussion of sample collection procedures is in Section 5.0. Drilling and well installation in the plume area are problematic due to the age and nature of the neighborhood, which is densely developed residential and commercial, with narrow lots and public right of ways, relatively busy streets, and a high density of underground and overhead utilities. There are relatively few open areas. In addition to work on several private properties, SulTRAC anticipates that project field activities will be conducted in public right-of ways and will be an iterative process, whereby data collected early in Phase I will be used to focus and optimize the efficiency of subsequent Phase I activities. For these reasons, this project will require close coordination with local utility providers and locators, as well as the City of Xxxx. Procedures for obtaining access to work sites are detailed in the Site Management Plan and Health and Safety Plan for the Phase I RI of the East Xxxx Site (SulTRAC 2010b, e). Before intrusive field work begins, several investigations will be conducted to direct intrusive sampling and modify proposed sampling locations as appropriate. Pre-intrusive field activities include a survey of existing monitoring xxxxx, a sewer survey, collection of groundwater elevation da...
