6 Facts and Figures: Agriculture uses 90%. Urban areas use the remaining 10%.There are 3000 natural wells on the Central Coast, 1900 of which are used for agriculture.A good portion of the 3000 wells are no longer viable.

11 What causes water scarcity? Human ConsumptionNatural Processes
12 Causes of Water Scarcity Human consumption is the number one cause of water scarcity.Examples of how Monterey County consumes water:1) vineyards2) manufacturing3) tourism4) landscaping5) residential6) agriculture
13 Causes of Water Scarcity Water is a limited commodity.Monterey County is dependent on regular rainfall to replenish rivers, aquifers and reservoirs.Two natural causes of water scarcity are drought and salt water intrusion.
14 Salt Water IntrusionHistoryDefinitionAccording to the Monterey County Water Resources Agency, local governments have been working on the problem of water scarcity for 65 years. As early as 1930, Monterey County cities began to discuss the problem of saltwater intrusion.Underground erosion causing salt water to leach into the ground water.
15 Salt Water Intrusion Salt water intrusion can occur for two reasons. 1) Mother nature and time will cause slight changes in the aquifers of tidal areas.2) Human growth expedites the process by pumping too close to the coast, thereby exasperating natural erosion patterns and speeding up salt water intrusion.
18 GroundwaterGroundwater is water that is stored underground in what is called aquifers.This water can be pumped to the surface for us to use.It is commonly used for agricultural irrigation.Because it is so widely used for agriculture, it can contain agricultural contaminants, like:Nitrates
19 RunoffRunoff is water that originates as precipitation, in the form of rain or snow.Gravity causes this water to flow down towards sea-level in rivers and streams.Rivers can be dammed to collect that runoff water, so it can be used by people.Damming a river, or pumping water directly from a river can have detrimental effects on the river ecosystem.On the Monterey Peninsula, a majority of the water we use is pumped from the Carmel River.State regulators have restricted our use of Carmel River water, and we must reduce our pumping from the river by 70% by 2016.Endangered Steelhead trout use the Carmel River as a tributary to spawn.Our pumping of water from the river leaves little left for the Steelhead to swim in upstream to spawn.
20 DesalinizationDesalinization is the process of taking water from the ocean, and turning it into fresh water by removing the salt and other minerals dissolved in it.This method is great for coastal communities, since the ocean’s salty water constitutes 97% of all of the precious life blood on the planet.The unfortunate side of the desalinization process is that it requires massive energy expenses to purify the water, and negative environmental effects can result from poor management of:where the water is pumped fromwhere the salty brine that is left over after the water is purified is disposed ofTwo main methods of commercial desalinization:DistillationReverse Osmosis

33 New Ideas to get WaterDesalinationIceberg Transport
34 Desalination-The process of removing any excess dirt, salt, or anything else that makes water undrinkable.- Seen by most experts as the best way to bring clean water to high drought areas
35 Iceberg TransportTaking icebergs that have broken off of glaciers and polar ice caps.More of a theoretical solution to getting water to MontereyThey are most often transported to keep them from bashing into oil ships.
37 Iceberg Costs Very high risk Icebergs contain 20 billion gallons of clean drinkable water, that’s if you didn’t have to move it.As opposed to the modern supertanker that can hold 100 million gallons.$ per mile in transport, and a portion of the iceberg is lost every mile as well.
38 Cost for DesalinationAdds up to around that $100 dollars a year, for the households that receive the desalinated water.The plant can run for $300-$600 million.To produce 50 million gallons of drinking water a day.
41 Monterey County Decisions -June, : 6-1 vote taken in favor of a new water fee-Sources say that the plan is to have a desalination plant here in Monterey County.-It would be less costly for the area than doing a regional desalination.- All in order to produce more fresh water and to stop extracting water from the Carmel River.
42 Water ConservationConserving water is by far the most cost effective way of increasing our water supply.Native plant landscaping, subsidized replacement of water-using appliances, and using gray water are all methods that can conserve a community’s water supply.What else can you do?Turn off the sink when you brush your teeth.Take shorter showers, or shower with a friend ;)If it’s yellow, leave it mellow, if it’s brown, flush it down.*An average American uses 2,000 gallons per day
