Methods:	Well Construction/Installation: Hyporheic samplers consisted of a 1/8 inch O.D. stainless steel (S.S.) tube housed in a 3/4 inch CPVC pipe. At the lower end of the CPVC a rubber stopper was inserted with the S.S tube protruding ten centimeters. A coupler was then used to attach a length of well screen to protect the S.S. tube. Tygon tubing was slid onto the top end of the S.S tubing and a three-way Pharmaseal stopcock was inserted into the tubing. Samplers were inserted into the stream bed by forcing a pry bar into the stream bed to a depth of the maximum depth allowed, typically 30-60 centimeters. The sampler was then worked down into the hole and the pry bar removed, allowing the hole to cave in onto the sampler. The length of the sampler, still above the substrate, was measured and subtracted from the total length to find the depth of the sampler in the substrate. Samplers were allowed to settle before any testing occurred. Sample collection: Samples were collected via a 60 mL syringe directly from the sampler after drawing 30 mL out to purge the interior of the sampler. Samples were filtered through a 25 mm diameter 0.2 um cellulose acetate syringe filter in the field. Sample Analysis: Samples were analyzed for their bromide concentration by HPLC on a Dionex AS4A Anion column. Notes: The D/D (River Distance) is in reference to the riffle position. Use the D-H (Distance from riffle head) for additional location information. River distances ae in reference to established river markings. (11) VARIABLE DESCRIPTIONS: Precision Coded?
