If the soil becomes saturated, oxygen may become scarce and in anoxic conditions, denitrifying bacteria may convert the nitrate to nitrogen gases (NO, N2O, and N2). Nitrogen converted to these gases becomes unavailable for plant uptake or for surface water contamination. Additionally, saturated soil during the growing season is harmful to many crops like maize that cannot tolerate low oxygen concentrations in the root zone for more than a few days. Surface runoff has the capacity to transport soil, vegetation, and surface applied granular fertilizers from agricultural fields to surface water bodies. If a granular form of nitrogen fertilizer had been applied immediately prior to the event that caused the surface runoff to. | 0 IS ỉ Water Efficiency Saves Energy Reducing Global Warming Pollution Through Water Use Strategies For more information please contact Michelle Mehta at 310 434-2300. The collection distribution and treatment of drinking water and wastewater nationwide consume tremendous amounts of energy and release approximately 116 billion pounds of carbon dioxide CO2 per year as much global warming pollution each year as 10 million The energywater connection is particularly strong in the driest regions of the United States such as the Southwest where significant amounts of energy are used to import water. Solutions exist to cut both water and energy use. Through water efficiency measures we can help to protect dry areas from drought lower consumers utility bills and reduce global warming pollution. NRDC The Earth s Best Defense policy March 2009 Natural Resources Defense Council The Energy - Water Connection Providing households with safe drinking water and wastewater disposal is an energy-intensive process. Nationwide about 4 percent of power generation is used for water supply and treatment but in certain parts of the United States the number is far higher. California is particularly vulnerable the water sector is the largest energy user in the state estimated to account for 19 percent of the total electricity consumed. Reducing water consumption saves energy because less water needs to be treated and pumped to end users. Moreover when energy use is reduced water is saved because less is needed in the operation of power plants. Some thermoelectric power plants for example use 136 billion gallons of freshwater a day which translates into 25 gallons of water to produce each kilowatt-hour of Water Efficiency Saves Energy Reducing Global Warming Pollution Through Water Use Strategies ễ Water conservation and efficiency measures reduce the burden on these energy-intensive water systems. There are ways to cut down on energy use and greenhouse gas
