Current Equipment
Field Sampling
Started: 2010-06-01Grab samples were taken from freely flowing areas of the stream in a 2-L HDPE bottle. The bottle was rinsed three times with stream water before the sample was collected. A full two liters of stream water was collected with no air bubble left in the bottle. Stream water was either filtered on-site or by the end of the day. The bottle was stored in a cooler until the water was filtered. Samples were filtered using a 0.45 µM membrane filter and a reusable Nalgene polysulfone filter holder. The filter was flushed with 250 mL of DIW, then 50 mL of stream water. Field pH was measured on this subsample. An additional 500 mL of sample was filtered and split into separate bottles for metals (LDPE; acidified to pH<2 with nitric acid), DIC (borosilicate glass, no headspace in the bottle), DOC (borosilicate glass), and a bottle with sample for the rest of the analyses (500 mL LDPE, no headspace in the bottle). All bottles were stored in a cooler until return to the lab. In the lab they were stored at 4°C.
Laboratory Measurement Methods
Started: 2010-06-01Samples were measured in the laboratory for the following analytes: pH | Potentiometric, ANC | Modified gran titration, Anions (F-, Cl-, SO42-, NO3-, PO43- | Ion chromatography, Monomeric aluminum fractions | Colorimetric (pyrocatechol violet method), DIC | Combustion with a non-dispersive infra-red detector, DOC | Persulfate-UV oxidation, Metals (Si, Mg, Ca, Al, Na, K) | ICP-MS, NH4+ | Colorimetric (indophenol blue method), Total nitrogen | Combustion with a chemiluminescence photodiode detector
