Human Water QualityLivestock Water QualityHuman Water QuantityLivestock Water Quantity
Needs Assessment Results
1. BMP’s on rangeland2. Small acreage ownership3. Urban/agriculture interface
Public Concern as Stated to County Agents
Needs Assessment Results
1. Salinity issues (soil & water)2. Livestock drinking water quality3. Nutrient impacts to surface and ground water
County Agents Response to BMP’s & Production Agriculture
Needs Assessment Results
1. Industrial water use (biofuels, oil)2. Water Conservation3. Water permitting process
Water Conservation and ProtectionWater Policies
Needs Assessment Results
Permitting process – somewhat concernedWater discharge – somewhat to not concerned
Agricultural Water Conservation and ProtectionTile Drainage
Needs Assessment Results
1.Testing water2.Quality of water3.Understanding the test result
Livestock Drinking Water
Needs Assessment Results
1.Quality of water2.Contamination of water source3.Understanding test results
Human Drinking Water
Our Response
• Proposal to Research Center Directors• News releases developed for state and local papers
Test Water Samples at Field Days Across the State
Our Response
• Agreement with private laboratory for reduced bacteria test pricing
• Sent packets to each county including sterile bottles and sampling information
Test Water Samples at Field Days Across the State
Field Days 2008
Field Days 2008Comments:Very hard waterSmelly, bad color, bad odorBacteriaReplace faucets often, yellows laundryWhite spots on grassBrownCauses throat pain
Field Days 2008Sample source:BarnHouse – pre & post treatmentSloughDamWellRural water system
Field Days 2008Nitrates (NO3-N)Hach colorometric
Human drinking water - 10mg/LLivestock - <90mg/L
Our findings: 0->50mg/L2 samples in SW ND 10mg/L1 sample in central ND at >50mg/L
Field Days 2008TDSHand held EC meter
Our findings: <100 – 16,000mg/L
Recommended levels:Human drinking water - < 500 mg/LLivestock water - < 5,000mg/L2 blind cows

Our findings 7.0 – 10.3
Most in the 8-9 range
Field Days 2008HardnessHach titration method
Largest water quality complaint
Our findings – majority >25 grains
ConclusionsMore education needed for private well users. More education needed for county staff in sampling
and understanding results and treatment.Speed up process by purchasing new equipment for
next year. Keep samples for future educational opportunities.Work more closely with counties on advertising.Share data with MPU’s.

Children watching with great interest!!!
Impacts
Interviews with TV, radio, news papers.
Raised awareness of county agents, experiment stations and staff…some even brought in samples from the experiment stations!
