Description:
This report presents the findings of a study on the long-term effects of applying treated domestic wastewater to farmland at Dickinson, North Dakota. On the test site, slow rate irrigation, using the border-strip method, has been practiced since 1959. Water, soil, and crop samples from this test site were compared with similar samples from a nearby control site irrigated with well water. Samples were also taken to detect coliform bacteria. Thirteen parameters were found to be present at significantly greater concentrations in the effluent used to irrigate the test site than in the river water used to irrigate the control site. Total coliforms were occasionally found in control and test site wells.
