Abstract
These are instructions for using the Qiagen Power Water Kit for doing Extraction from drinking water samples
Troubleshooting
Before start
Solution PW1 must be warmed at 55°C for 5–10 minutes to dissolve precipitates.
If Solution PW3 has precipitated, heat at 55°C for 5–10 minutes to dissolve precipitate.
 Shake to mix Solution PW4 before use.

Insert the filter into a 5 ml PowerWater DNA Bead Tube.
Add 1 ml of Solution PW1 to the PowerWater DNA Bead
Secure the tube horizontally to a Vortex and tape it extensively
Vortex at maximum speed for 5 min. Centrifuge the tubes ≤4000 x g for 1 min at room temperature
Transfer the supernatant to a clean 2 ml Collection Tube Draw up the supernatant using a 1 ml pipette tip by placing it down into the beads.
Centrifuge at 13,000 x g for 1 min at room temperature.
Avoiding the pellet, transfer the supernatant to a clean 2 ml Collection Tube (provided).
Add 200 µl of Solution IRS and vortex briefly to mix. Incubate at 2–8°C for 5 min.
Centrifuge the tubes at 13,000 x g for 1 min.
Avoiding the pellet, transfer the supernatant to a clean 2 ml Collection Tube (provided).
Add 650 µl of Solution PW3 and vortex briefly to mix.
Load 650 µl of supernatant onto an MB Spin Column. Centrifuge at 13,000 x g for 1 min. Discard the flow-through. Repeat until all the supernatant has been processed.
Place the MB Spin Column Filter into a clean 2 ml Collection Tube.
Add 650 µl of Solution PW4 (shake before use). Centrifuge at 13,000 x g for 1 min.
Discard the flow-through and add 650 µl of ethanol and centrifuge at 13,000 x g for 1 min.
Discard the flow-through and centrifuge again at 13,000 x g for 2 min.
Place the MB Spin Column into a clean 2 ml Collection Tube
Add 100 µl of Solution EB to the center of the white filter membrane.
Centrifuge at 13,000 x g for 1 min. 23. Discard the MB Spin Column. The DNA is now ready for downstream applications.
