Manure contains four primary contaminants that impact water quality: nitrogen, phosphorus, bacteria and other pathogens, and organic matter.

In many parts of Nebraska, the natural quality of groundwater is suitable for both humans and ecosystems. However, in some areas the groundwater quality has been impacted by high levels of nitrate from human activities, or naturally high levels of uranium or arsenic. These groundwater quality issues can cause significant challenges for communities, in part because of the cost of treating groundwater to reduce contaminants to meet drinking water standards.

Problems sometimes occur. Some of the problems that occur include: sluggish drainage, contaminated drinking water, wastewater surfacing in the yard, odors, and pipes freezing.

Advantages to furrow irrigation include lower initial investment of equipment and lower pumping costs per acre-inch of water pumped. Disadvantages include greater labor costs and lower application efficiency compared to sprinkler and subsurface drip irrigation. The number of furrow irrigated acres in Nebraska has decreased from 2.4 million to approximately 1.5 million acres in the past 10 years.

An annual crop nutrient management plan is needed to ensure an adequate supply of nutrients to sustain profitable crop production, and to balance nutrient inputs (including manure) with crop nutrient needs. Title 130 of the NDEQ requires that a permit application include a nutrient management plan with manure sampling and analysis procedures, soil sampling and analysis procedures, and planned land application rates, methods, and frequencies.

An important soil characteristic, the percolation rate, measures how long it takes water to drop one inch in a saturated hole dug in soil. Fast: 1 inch in 3 minutes (sandy soil). Slow: 1 inch in 48 minutes (clay soil). If it takes less than 5 minutes for the water to drop 1 inch in a saturated hole, the effluent will move too rapidly to be treated properly, such as in sandy soil.

Livestock Waste Regulations in Nebraska are enforced by the Nebraska Department of Environmental Quality NDEQ). NDEQ administers both state and federal (EPA) environmental regulations. The governing regulations are called Title 130, Livestock Waste Control Regulations.

The ability of soil to accept water or for water to travel through soil is called soil permeability. Percolation is the movement of water through soil. A soil percolation test is designed to measure the rate of water movement in saturated soil (mimicking conditions that soil treatment systems have) so that one can decide the appropriate type and size of treatment system.

The key premise of low impact development (LID) is to allow natural systems to manage stormwater when and wherever possible.  LID takes advantage of existing natural features and also designs and constructs systems to imitate natural processes, for example, green roofs, bioretention gardens, and permeable pavement.
