To be used in the event that the primary method cannot be used or needs to be confirmed, i.e. automated method cannot be used due to instrument failure. 5 Albion Laboratory is the primary laboratory for metals analyses. LCRA is listed as back up to the primary lab. Both labs will meet all requirements of the QAPP before being sent samples for analyses. 6 and UGRA have done studies that show that their AWRLs for these tests are lower than the prescribed AWRLs. Will report lower than the listed AWRL, with acceptable recovery. ( chl a reporting limit = 1.0 ug/l; Tot P reporting limit = mg/l; UGRA Tot P reporting limit = mg/l).
