11.0 ELECTRONIC DATA MANAGEMENT AND REPORTING 11.1 Data Acquisition Systems

The primary data acquisition system for the continuous monitors and the meteorological system will be the CSI CR510 data logger. The data logger has inputs for 4 single-ended analog channels. Each data channel will be sampled once per second with an accuracy of + 0.1 percent of full scale. Both 5-minute and hourly averages will be calculated. The data loggers are programmable, and additional information such as maxima, minima, and frequency histograms can be collected.

11.2 Data Management

The current Contractor Environmental Subcontractor has developed an ensemble of systems for electronic data management of nearly all phases of environmental monitoring projects that will be used to manage the collection and reporting of data from this project. These systems, or equivalent, will be utilized for the management of data:

EnviroData® provides a standardized means for porting laboratory electronic data deliverables (EDDs) into Microsoft® Access® databases;

MonitorFast®^ provides a framework for automated data retrieval from monitoring stations to standardized SQL Server databases either periodically or in real-time;

• FieldFast enables direct electronic entiy of field sampling data from the Asbestos, PUF and TSP samplers; and

TeamLink®^ provides a secure Web-based data access portal and project management tool.

Each of these technologies is described further in Appendix A of this document.

11.3 Reporting

Samples will be shipped overnight to the laboratory the day after the sample period. Please refer to Table 7 for proposed laboratory turnaround times on a parameter specific basis. Data reporting schedules and frequencies are also provided. PAHs, PCB, and D/F’s data collected are loaded to the EnviroData database, or equivalent on Contractor Environmental Subcontractor’s server within 48 hours of receipt of the EDD from the laboratory. The data can be viewed in tabular format through the Teamlink®^ Website, or equivalent.

For continuous monitors and the meteorological station, the data loggers will record data at Sminute and 60-minute intervals. The data will be downloaded from the loggers to the databases on a minimum of once daily, and reviewed by the Contractor Environmental Subcontractor Project Scientists. The frequency of data retrieval can be increased in MonitorFast®^ , or equivalent to obtain access to results in near-real time.
