NALGENE STORM WATER SAMPLERS
Installation – Single Unit Within Flow Path
Personnel Needed: 1-2 field personnel 4-6 hours to install 3 samplers
Equipment Needed (assumes use of Nalgene units):
• three (3) Nalgene Storm Water Samplers [Cat. No. 1100-1000 (HDPE) and/or 1120-1000 (Glass)
depending on targeted pollutants of concern]
• three (3) Nalgene Storm Water Mounting Kits (includes mounting tube, clamp, wire hanger, cable tie,
and mounting stake)
• slot-headed screwdriver
• flagging
• shovel
• digging bar
• Nalgene Installation Guide
• lock
Installation:
Note: The most effective installation materials, housing and configuration for each station will depend upon
site conditions and limitations. Trained and experienced field personnel should be used to ensure proper and
safe installation of equipment.
Note: The Storm Water Sampler should be used during installation of the Storm Water Mounting Kit to ensure
the setup will properly collect a sample. To avoid contamination the sampler should not be left on-site. It
should be installed in the mounting tube just prior to an anticipated runoff event.
1. Follow the instructions provided in the Nalgene Installation Guide, briefly summarized below.
a. Grate mounting
i. Hang mounting tube from stormwater grate near the edge of the storm drain chamber using
wire hanger (provided in mounting kit), cable, or string.
b. Ditch mounting
i. Dig a hole deep enough to set the sampler at grade. Be sure to place dirt at the downstream
end of the hole.
ii. Drive mounting stake into downstream side of hole with open side of V facing upstream.
iii. Set mounting tube at grade and secure to stake using screwdriver and clamp.
iv. Backfill the hole, ensuring that water is directed towards the passive sample.
2. If necessary, secure Mounting Kit against vandalism using lock.
3. Test placement of Storm Water Sampler within Mounting Kit. Use level to ensure sampler rests
evenly on housing. Make any adjustments necessary.
