16

* Sterile Bottle, * Remove aerator and disinfect end of faucet, * Sodium Thio-Sulfate to neutralize chlorine, * Do not rinse out bottle, * Do not touch inside of bottle or cap with fingers, * Need 100ml of sample, * 30 hour hold time, 17

 Depending on where you are first class US Mail is now a 2 – 3 day service.  No matter which lab you are using, bacteria and nitrate samples will have to be rejected if they do not make it to the laboratory within 30 hours for bacteria and 48 hours for nitrates. 18

* It is recommended to collect bacteria water sample’s at a fixed bathroom faucet with the aerator removed, (Hose bibs and kitchen faucets with swivel arms are not recommended locations for bacteria sampling). 19

* PWSID Number, * System Name, Address, * Contact name & Phone #, * Collection Date & Time for each sample, * Sample location (kitchen faucet; bar sink; raw water tap; etc…), * Chlorine Residual,  Reminder: All CWS & NTNC systems that chlorinate must take and record chlorine residuals for any Total Coliform bacteria sample. * Signature, * Is this a compliance sample? 20

Just return to the lab with your sample. 27

* Remove any screen, hoses and aerators from end of faucet. * Run COLD water for 3 to 5 minutes to make sure water has not been sitting for a long time in pipes or tanks and is fresh from the well. * Turn water down to a flow rate slow enough so you can collect the samples without splashing. * Remove cap from vial.
