“…For example, median nitrate concentration in groundwater samples from the Minidoka Irrigation District in the Upper Snake River Basin, southeastern Idaho, is 7.1 mg/L ( Figure 6). The area receives high nitrogen loading from fertilizer (151 kg/ha) and has well-drained soils and a shallow depth to groundwater (33).…”

Results of a national water quality assessment indicate that nitrate is detected in 71% of groundwater samples, more than 13 times as often as ammonia, nitrite, organic nitrogen, and orthophosphate, based on a common detection threshold of 0.2 mg/L. Shallow groundwater (typically 5 m deep or less) beneath agricultural land has the highest median nitrate concentration (3.4 mg/L), followed by shallow groundwater beneath urban land (1.6 mg/L) and deeper groundwater in major aquifers (0.48 mg/L). Nitrate exceeds the maximum contaminant level, 10 mg/L as nitrogen, in more than 15% of groundwater samples from 4 of 33 major aquifers commonly used as a source of drinking water. Nitrate concentration in groundwater is variable and depends on interactions among several factors, including nitrogen loading, soil type, aquifer permeability, recharge rate, and climate. For a given nitrogen loading, factors that generally increase nitrate concentration in groundwater include well-drained soils, fractured bedrock, and irrigation. Factors that mitigate nitrate contamination of groundwater include poorly drained soils, greater depth to groundwater, artificial drainage systems, intervening layers of unfractured bedrock, a low rate of groundwater recharge, and anaerobic conditions in aquifers.

“…Contaminants can enter the lower Columbia River from many sources, including municipal and industrial permitted discharges, atmospheric deposition, urban and industrial nonpoint pollution, and runoff from agricultural and forested areas (Fuhrer et al, 1996;LCREP, 2007). In addition to inputs from the lower Columbia region, contaminants may also be transported to the lower river from areas of known contamination above Bonneville Dam, e.g., the Yakima (Fuhrer et al, 2004) and Snake (Clark et al, 1998) Rivers.…”

“…Very little groundwater recharge occurs in the non-irrigated areas, but recharge from excess irrigation water can occur in irrigated areas, potentially transporting nitrite plus nitrate as nitrogen (nitrate) and pesticides with it. Precipitation in adjacent mountains and tributary valleys can be 45 to 60 inches or more; (6,7) runoff from these mountainous regions provides surface-water irrigation waters and groundwater recharge to lower elevation areas.In contrast, Oahu has a subtropical climate. Temperatures are mild and vary little.…”

Library of Congress Cataloging-in-Publication DataRupert, Michael G., 1959-The quality of our nation's waters---groundwater quality in the Columbia Plateau and Snake River Plain basin-fill and basaltic-rock aquifers and the Hawaiian volcanic-rock aquifers, Washington, Idaho, and Hawaii, 1993--2005 ForewordThe United States has made major investments in assessing, managing, regulating, and conserving natural resources, such as water and a variety of ecosystems. Sustaining the quality of the Nation's water resources and the health of our diverse ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken together, these actions lead to immediate and long-term economic, social, and environmental benefits that make a difference to the lives of millions of people (http://water.usgs.gov/nawqa/applications/).Two decades ago, Congress established the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program to meet this need. Since then NAWQA has served as a primary source of nationally consistent information on the quality of the Nation's streams and groundwater, on ways in which water quality changes over time, and on the natural features and human activities affecting the quality of streams and groundwater. Objective and reliable data, systematic scientific studies, and models are used to characterize where, when, and why the Nation's water quality is degraded-and what can be done to improve and protect the water for human and ecosystem needs. This information is critical to our future because the Nation faces an increasingly complex and growing need for clean water to support people, economic growth, and healthy ecosystems. For example, NAWQA findings for public-supply wells, which provide water to about 105 mil...
