Sampling Instructions - Please Read Before Starting

Step 1

After the blue ice pack has been in your freezer for at least 8 hours, you can collect your water sample from an appropriate water faucet or spigot. If the spout has a strainer or aerator, remove it prior to sampling

Step 2

Samples must be shipped the same day they are collected via guaranteed next day delivery and must be collected after 1:00 p.m. EST to minimize time in transit. Do not collect and/ or ship your samples on a Friday, Saturday, Sunday, or the day before a National Holiday.
Fill both of the bottles, in order from 1 to 2 as shown in the picture to the right.

Bottle 1 - Before filling this bottle, disinfect the end and inside of the faucet spout using rubbing alcohol. After the faucet spout has been disinfected, flush it by running the water for 3 - 5 minutes. Remove the red tabbed plastic seal on the 125 mL plastic bottle. Do not touch the inside of the bottle or the inside of the cap. This bottle contains preservative. Do not rinse the preservative out of the bottle. Fill the bottle between the 100 mL and 120 mL fill lines. Do not fill any less or more as this will impact the analysis. [ see picture]. Replace the cap securely making sure not to touch the inside of the bottle or the inside of the cap.
