Phase I Yet to do: Assess data Determine information and education for landowners and general public
31
Phase II2009 7 COUNTIES SAMPLE 1 TILE DRAIN FOR WATER QUALITY ONLY CASS COUNTY INSTALLS AUTOMATED EQUIPMENT FOR FLOW RATE, WATER QUALITY, AND PRECIPITATION
32
Phase II2010 4 COUNTIES CONTINUE SAMPLING 1 TILE DRAIN FOR WATER QUALITY GRAND FORKS, RICHLAND, AND SARGENT COUNTIES INSTALL AUTOMATED EQUIPMENT FOR FLOW RATE, WATER QUALITY, AND PRECIPITATION
33
Phase II 2009-2013 Water quality samples taken at Drain or lift station (automated sampler) Downstream location within a mile from the tile outlet Surface runoff of tiled field (automated sampler) Surface runoff of comparable un-tiled field Flow measurements taken at Drain or lift station (flume/weir) Surface runoff of tiled field (in automated sampler) Soils must be salt affected Soil Samples at 4 sites Rain gauges – Automated or Dewey To determine the effect tile drain effluent from saline soils has on water quality in tributaries of the Red River.
34
Phase II 2009-2013 Project Coordinators and Partners: Work with SCD’s to locate proper sites for sampling Meet with producers as needed Build and/or install equipment Coordinate training of sample collectors and oversee the collection and transportation of samples to the ND Dept of Health Download data from the automated equipment at sites Develop BMPs for landowners Prepare and present results of the assessment to the public

Phase II 2009-2013 Funding: North Dakota State Water Commission Cass County Soil Conservation District EPA 319 Nonpoint Source Pollution CSREES Northern Plains Regional Water Quality Program
