For information on testing water for human consumption in Oklahoma, contact the Oklahoma Department of Environmental Quality. Individuals living in Texas can contact the Texas Commission of Environmental Quality. Most Cooperative Extension Offices can provide information and supplies needed for this type of testing.
Water analysis indicates:
Take a sample of water to be used for agricultural purposes under the conditions in which the water will be used. You may want to take samples at several processing stages or time periods.
Sample containers should be clean and made of plastic. For complete analysis, a minimum of half a pint (8 ounces) of solution is required. Before filling the container, rinse it thoroughly with the solution being collected. Fill the container completely and screw the cap on tightly. Label the container with your name and the sample identifier.
Complete all appropriate blanks on the information sheet(s) and write legibly. Be consistent from year to year in listing name, farm name and/or address. Also, check to make sure the sample ID on the form corresponds to the one on the water sample. Testing takes about seven to 10 working days to complete from the time we receive your shipment.
Place information sheets inside the shipping container with the samples and keep a copy for your records. It is a good idea to place information sheets inside a sealed plastic bag to keep them clean and legible in case your sample bottle leaks.
Do not send cash or check. When you receive your test results, you will receive an invoice from our contract laboratory for testing analysis. Servi-Tech Lab testing cost information is located in the Test Analysis Pricing Sheet.
For assistance in interpreting water quality results, please refer to the Noble Research Institute Livestock Water Guidelines, Irrigation Water Guidelines, Noble Research Institute consultant or a county Cooperative Extension agent.
Some parameters such as pH and dissolved oxygen in surface waters (ponds, lakes, rivers and streams) should be measured on site because diffusion and biological activity in water cause these parameters to change after a water sample is collected.
