SAMPLE CONTAINERS

Samples being tested for coliform bacteria should be collected in a sterile container. SDHD provides the containers at no charge. If a bacteria test is requested and the sample is submitted to the lab in a non-sterile container, the results could be impacted and the lab may have to qualify the test results accordingly.

Water that is chlorinated must be collected in a bottle that contains a chemical that neutralizes the chlorine. If chlorine is not neutralized prior to analysis, the bacteria results may be inaccurate and the lab may have to qualify the test results accordingly. 

Bottles that contain the chlorine neutralizer cannot be used for chemical testing.

SAMPLING LOCATION

Samples collected from fire hydrants, yard hydrants, dirty or leaking faucets, hoses, or soft water systems may give false results by introducing bacteria into the water.

COLLECTION INSTRUCTIONS

• Sample bottles are sterile, so be careful not to contaminate inside of bottles or caps.
• Don’t remove the cap until you are ready to fill the bottle.
• Do not rinse bottle out.
• If possible, remove aerator and wire screen from end of faucet.
• Open cold water faucet and allow to run 2-3 minutes.
• Carefully remove cap and fill bottle to shoulder without splashing.
• Replace cap immediately and secure tightly.
