Sampling on Wednesday, April 30, 2003 at 15:05.
Notes: NMED has sampled this spring since 1994. The water chemistries are different from Spring 3 to Spring 3AA.
- LANL/EES-6 took a 1 L water sample for inorganics (calcium, cesium, magnesium, nitrate/nitrite, nitrogen, potassium, sodium, uranium), trace metals, major anions and cations by the IC method.
- LANL/WQH took a 250 ml water sample for low-level perchlorate testing by the LC/MS/MS method.
- NMED helped LANL collect their samples. NMED took a 1 L water sample for the NMED Groundwater Bureau for nitrogen species, trace metals and anions and cations.
