Nitrate in Kansas Ground Water. Townsend and D. Young, Geohydrology, Kansas Geological Survey Introduction. Ground water is the major source of drinking water for 70% of Kansas residents. In rural areas, 85% of the population relies on ground water. Concentrations of nitrate-nitrogen in the inner Coastal Plain, particularly in areas of well-drained soils, show that ground water concentrations can exceed the 10 mg/L MCL.
Low nitrate-nitrogen concentrations of the outer Coastal Plain are coincident with high ammonium and high dissolved organic carbon. The concentration of nitrate-nitrogen is shown in the following figure.
The concentration expressed as milligrams/liter (mg/L) is the same as parts per million (ppm). The safe drinking water standard for public water supplies is 10 ppm (or 10 mg/L) of nitrate-nitrogen. Nitrate concentrations in groundwater were retrieved from the Danish Groundwater Monitoring Progra which has been running since in Cited by: Ground-water nitrate data in some areas did not conform to risk patterns shown in figure 1.
For example, median nitrate concentration in ground-water samples from eastern North Dakota (shown in red on the national map) was. Fifty-three wells were selected across the growing areas of the three cropping systems to monitor changes in groundwater nitrate dynamics over 1 year.
There were 18 wells distributed in the wheat–maize fields, 18 in the greenhouse areas and 17 in the apple orchard areas.
The wells were selected using three by: Nitrate-Nitrogen Losses to Groundwater from Rural and Suburban Land Uses Article (PDF Available) in Journal of Soil and Water Conservation 45(2) March with 88 Reads How we measure 'reads'.
Decadal-scale changes of nitrate concentrations were evaluated in ground water samples collected from wells in 24 well networks across the United States in predominantly agricultural areas. A well network is a set of about 30 randomly-selected wells designed to examine ground-water quality in a particular region.
the nitrate-nitrogen and total nitrogen concentration at the same well. Total nitrogen includes nitrite, nitrate, ammonia and nitrogen in organic matter Nitrate – nitrogen concentrations in the ground water samples ranged from mg/L to mg/L.
None of the samples contained nitrate-nitrogen above the Canadian Drinking Water Guideline of Drinking Water: Nitrate-Nitrogen Sharon O. Skipton, Extension Water Quality Educator much of Nebraska and concentrations are increasing in some areas.
Nitrogen is essential for all living things, as it is an nitrate-nitrogen in a public water supply is 10 milligrams per liter (mg/L) which can also be expressed as 10 parts File Size: KB. Concentrations of chemical constituents in water are given in milligrams per liter (mg/L).
Abstract. Trends in nitrate concentrations in water from wells in 17 subregions in the Columbia Basin Ground Water Management Area (GWMA) in three counties in eastern Washington were evaluated using a variety of statistical techniques, including the Friedman test and the Kendall test.
The data in this indicator show the total area and percent of state area predicted to have nitrate concentrations exceeding 5 mg/L, or half of EPA’s MCL, in groundwater used for drinking.
Also presented is the estimated percent of state populations served by self-supplied drinking water, 98% of which is from groundwater wells. Groundwater discharge to a lake can be an important component to water and nutrient budgets.
In this study, we evaluated groundwater loading of nitrate-nitrogen (NO 3-N) and phosphorus (P) to West Lake Okoboji, Iowa, using a watershed-based approach based on groundwater recharge and land cover objectives were to assess groundwater level fluctuations and nutrient concentrations under Cited by: 6.
The difference in nitrate concentration in ground water from these two areas in Harvey County indicates that fine-textured zones in the vadose zone and aquifer play an important role in decreasing the movement of nitrate to the ground water either by retardation of flow and/or permitting denitrification processes to occur.

Druliner, T. An assessment of nitrate concentrations in groundwater in the United States (US) indicates that concentrations are highest in shallow, oxic groundwater beneath areas with high nitrogen inputs.
A survey of groundwater samples collected between and from municipal, irrigation, domestic, and monitoring wells in Kansas showed that 50 %of the samples had nitrate-nitrogen (nitrate in this paper) concentrations between 2 and 10 mg/L (Townsend and Y File Size: 1MB.
movement of contaminated shallow ground water. Nitrate-nitrogen concentrations are grouped by well depth in the table. Concentrations from sampled springs are also listed. Data for a well were included in the table Ground-Water Quality in Kentucky: Nitrate-Nitrogen Philip G.
Conrad1, Daniel I. Carey1, James S. Webb2,File Size: 1MB. Major issues and findings - Nitrate in ground water Nitrate concentrations in many drinking water wells exceed the maximum contaminant level (MCL). In the Central Columbia Plateau, 84 percent of drinking water comes from ground water.
Both public supply and domestic water systems depend largely on ground water [5, 6]. Current nitrate data are generally available for public supply wells, which must. Nitrate concentrations of ground water increasing in many areas of the United States Nitrate is the most common chemical contaminant in the.
Canna A & B both list Nitrogen (N) - Nitrate Nitrogen Rhizotonic lists Nitrogen (N) - Water Soluable Nitrogen It's obvious that Nitrate Nitrogen is NO3 but I don't know which to use for the "Water Soluable Nitrogen".
If anyone can clue me in that would be great. Thanks. A regional assessment of multi-decadal changes in nitrate concentrations was done using historical data and a spatially stratified non-biased approach. Data were stratified into physiographic subregions on the basis of geomorphology and soils data to represent zones of historical recharge and discharge patterns in the basin.
Data were also stratified by depth to represent a shallow zone Cited by: The drinking water limit (10 mg of nitrate-measured-as-nitrogen per liter) is equivalent to 27 lb of nitrate-nitrogen in one acre-foot of water.
Groundwater recharge in irrigated agriculture is typically on the order of one acre-foot per acre. Why don't we just use well-head treatment for nitrate in well water used as drinking water.
This can. This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation. It begins by highlighting the nitrogen cycle and related health concerns, providing both background Cited by: Thus, drainflow from agricultural areas has significant influence on surface water eutrophica-tion.
The objectives of this study were to evaluate nitrate nitrogen and phosphate concentrations and load changes in drainflow using as an example clay soil analyzed in period spanning the years and This study showed limited impact of nitrogen application timing on nitrate-nitrogen concentrations.
However, five-year average annual flow-weighted nitrate-nitrogen concentration for the soybean phase with fall applied nitrogen to the previous corn crop had significantly lower nitrate levels when compared to the spring application : Ainis Lagzdins, Carl Pederson, Linda Schott, Emily Waring, Matthew Helmers.
nitrate and chloride concentrations in groundwater in an area of north-central Texas with agricultural activity, in addition to oil and natural gas exploration and production. Data were compiled from 40 water wells sampled in Nitrate concentrations in three wells exceeded the maximum contaminant level (44 mg/L) for drinking water.Nitrate sources in the environment include the decomposition of plants and animal wastes, human sewage and the application of fertilizer.
Nitrate (NO3) is a common constituent of ground water. It is made up of nitrogen and three oxygen atoms. The median level of nitrate in ground water in the U.S. is generally less than 2 parts per million.For the 72 NAWQA sites downstream from agricultural areas, mean annual nitrate loads were computed using the estimated daily nitrate concentrations for complete water years and The ratio of these loads to the upstream drainage area for each site was used to estimate mean annual nitrate yield, in mass per unit area.
