1 Appendix A: Measurement Performance Specifications (Tables A7.1 and A7.2) Measurement performance specifications define the data quality needed to satisfy project objectives. To this end, measurement performance specifications are qualitative and quantitative statements that: clarify the intended use of the data define the type of data needed to support the end use identify the conditions under which the data should be collected Appendix A of the QAPP addresses measurement performance specifications, including: analytical methodologies AWRLs limits of quantitation bias limits for LCSs precision limits for LCSDs completeness goals qualitative statements regarding representativeness and comparability The items identified above need to be considered for each type of monitoring activity. The CRP emphasizes that data should be collected to address multiple objectives, if possible, thereby maximizing the expenditure of resources. Caution should be applied when attempting to collect data for multiple purposes because measurement performance specifications may vary according to the purpose. For example, limits of quantitation may differ for data used to assess standards attainment and for trend analysis. When planning projects, first priority should be given to the main use of the project data and the data quality needed to support that use, then secondary goals should be considered. Tables A7.1 and A7.2 have been modified to reflect actual parameters, methods, etc. employed by the SRBA and its participants. Procedures for laboratory analysis must be in accordance with the most recently published edition of Standard s for the Examination of Water and Waste, 40 CFR 136, or otherwise approved independently. Only data collected that have a valid TCEQ parameter code assigned in the Tables are stored in SWQMIS. Any parameters listed in Table A7.1 or A7.2 that do not have a valid TCEQ parameter code assigned will not be stored in SWQMIS. Sulphur River Basin Authority QAPP Page 38
