What is MCLG
- the maximum level of contaminant in drinking water with no adverse affect on a person health, and which allows an adequate margin of safety. Not enforceable.
- * This is the goal they strive for.
-
What is Maximum Contaminant level (MCL)
- the maximum permissible level of a contaminant in water, which is delivered to any user of public water system.
- *Enforcable, this they can enforce.
-
What is SMCL's
National Secondary drinking water regulations set non mandatory water quality standards for 15 contaminants.Establishes only guidelines to assist public water systems, for taste, color and odor.
- * They set contaminants
- * all it does set any health issues.
-
California State water resource control board
- There are 9 Regional Water quality control boards in the state.
- *states can have laws that replace the federal law only if the state law are more stringent.
- *Bakersfield is Central valley
- * Antelope Valley is Lahontan.
-
What we have in water is
Total Dissolved Solids (TDS)
-
What is TDS (total dissolved solid)
- a measure of the combined content of all inorganic and organic substances contained in a liquid in:
- molecular, idonized or micor-granular suspended form.
- *the solids must be small enough to survive filtration (size 2 micrometer).
-
TDS rule
- water containing tds below 1000 mg/litre is usually acceptable.
- *High TDS is objectionable to consumer in taste, water pipes, heaters, boilers, and household appliances.
- *Under the Federal State Drinking Water act: Low TDS is also unacceptable b/c of its flat
- taste.
- * TDS is classified as secondary maximum contaminant. recommended max. level of 500 milligram per liter, but not required from public water system. state law may require.
-
What does EPA stand for
Environmental protection agency.
-
What are some contaminants that are tested
- Organics, they have carbons, gasoline, pesticides, solvents, degreasers, heat, refining, plastic, and manufacturing.
- *some are hard to detect b/c they dissolve in water.
-
Characteristic of organic contaminants.
- some are soluble in water such as Benzene, MTBE.
- some like to evaporate into the air-toluene, xylene.
- some are biodegradable if oxygen is sufficient.
- some like to cling to fatty tissues,PCB's, DDT, and DBCP
- gas stations, military bases, and airports.
-
How to remove organics?
- Pump and treat, skimming, biodegradation.
- treatment includes carbon filters, vaporization and biodegradation.
- Note Filters must dispose at a hazard waste site
-
How many waste sites are there in Kern Country and Av?
- There are two in Kern County :
- Edwards Air force base superfund sites
- and Arvin.
- One in the AV Edwards Air force Base.
-
Organic compounds
these tend to be more happy clinging to fatty tissues than to dissolve in water. they build up in bodily systems.
-
What is LNAPL?
Light non-aqueous phase liquids- floats on water table. ex. gasoline and jet fuel. tend to be biodegrade rapidly if they have oxygen.
-
What is DNAPL stand for
Dense non-aqueous phase liquids- sink through groundwater to the bottom of the aquifer. These form a separate phase too and are very hard to locate and clean up. Many are pesticides and don't biodegrade very rapidly.
-
Halogenated Organics
Organics combined with chlorine, bromine or fluorine. These tend to persist in the environment along with DDT, PCB's
-
Types of Metal
Lead, Mercury, Chromium, etc.
-
Characteristic's of Metal's
- tend to be soluble in water (not a good thing)
- not biodegrade, but some may build up fatty tissues or carbon filters
- may adsorb onto clay or salts
- Rick: cause birth defects, cancers, damage kidneys and central nervous system
-
What are non metals and anions
- Nitrates
- arsenic
- perchlorate
- selenium
- phosphates
-
Characteristic of non-metal and anions
- tend to be soluble in water,
- very mobile in the aquifer
- deadly to animals
- expensive treatment reverse osmosis to clean out of the water.
- Nitrates is the most deadly to small children and unborn children
-
risk factor of arsenic
- skin discoloration
- nation affected the most was Bangladesh.
-
Radionuclides- Radio Contaminants
- Break down over time some quickly some slowly.
- high level pose greater risk then lower level
- can enter the body by ingestion, inhalation absorption and injection.
- can cause cancers, uranium can cause cancer in the bones and effect on kidneys.
-
Biological Pathogens
- leading cause of pollution.
- sources sewage from human and animal waste- confined animal feedlots.
- can travel from storm water carry feces and bacteria to water supply.
- treated by chlorine.
-
Disinfection by product (Pathogens)
- common chlorine,chloramine and ozone.
- THM's are formed Tri-halomethanes.
-
Pharmaceuticals
- over counter medicines, cosmetics and personal care product such as shampoos.
- affect changes or hormone systems
-
Pollution Sources
- Septic tanks- can leak into the ground, sending nitrogen's or bacteria into the water supply.
- Gas Stations- alway get leaks.
- Salt Pile-from salt in the ground (snow)
- Waster containers- big source of leakage.
- Garbage landfill- can reach the ground water trash.
- Farm animal sewage- smells bad causes damage into the groundwater.
- Fertilizer- apply irrigation and pesticide, will be flush into the water suppy.
-
non-point sources of pollution the two main are
- refers to both water and air pollution from diffuse sources.
- Agriculture and
- Urban run off-Things that are thrown into the streets and goes into the storm drains.
- this is the leading cause of water pollution.
-
What is TMDL'S
- total maximum daily loads.
- requires that all sources of pollution and all aspects of a watershed's drainage system be reviewed
-
Laws that were set up
- 1968 Cuyahoga River in Ohio busted in flames due to chemical in the water.
- & Book release of Silent Spring by Rachel Carson in 1960's. mentions DDT- affects on bird.
-
National Environment Policy Act
- 1969 Federal government
- had to prepare an environment impact statement.
- California has CEQA California environment quality act.
- requires federal agencies to integrate values.
-
Clean Water Act
- 1972
- getting those who would dump thing into the pipes.
- Goals- are fishable, swimmable rivers and lakes and the elimination of pollutant. the sewage had to be treated. and
- San Francisco was the last in CA to get a sewage act.
-
Safe drinking water act
- 1974.
- EPA set up the maximum contaminant levels
- The setup of MCLS
-
-
Resource Conservation and Recovery Act
- 1976
- the cradle to grave act
- dealing with the solids waste and illegal dumping.
- anyone that needs to generate waste they need a manifest system RCRA
-
CERCLA aks Superfund
- 1980- Comprehensive environmental response, compensation, and liability act.
- $8.5 billionto study and clean up.
- Funded 70 percent superfund activities
- total collected 1.6 billion in 2003 ran out of money.
- purpose to identifying and cleaning up contaminated sites
- Edwards and Arvin out of the general fund of taxpayers.
-
Average annual precipitation
- California is about 200 mm ac ft. precipitation.
- We only capture runoff 25% lost to runoff to the ocean 11%
-
The majority of California wetlands was
- Central Valley
- California contained over 5 million acres
- 200,000 acres of coastal marshes along SF bay only 35,000 remain
-
what was the largest lake in california
- Tulare Lake
- followed by Buena Vista and Kern Lay to the south
-
Vast system of lakes and wetlands that served as discharge areas for the Tulare Aquifer
The San Joaquin Valley
-
The flowing Artesian well
- one in Bakersfield
- decreased as the underground aquifer was depleted.
-
What was and still is the largest estuary on the west coast of north america
The Sacrament- San Joaquin Delta
-
Southern California was
- mostly coastal Marsh.
- the Salton Sink (sea) the largest lake in California. flood in 1906 from the colorado river evaporation of the hot climate cause salinity in the water
-
Owens Lake
- Today Owen's lake is dry
- located east of the sierra nevada mountain.
-
History Native Americans
- they located where water was located.
- they didn't bring the water to them.
- water and land could not be sold.
-
The Spanish Era
- 1769-1821
- Nature was a divine gift to be subjugated and exploited in the name of god and civilization.
- All water belong to the king of Spain.
-
Missions
- located near water
- native work on canals and irruption.
- when the indians were civilized, the mission were then transformed into pueblos with the land given to the inhabitants.
-
Presidios
Military Fortifications, expected to grow own food and clothes. goal was to eventually become a pueblo
-
Ranchos
- Dry land but they couldn't use water to irrigate after 10 years of irrigating and no one complained you could continue to do so.
- They were allowed to take water from the pueblos
-
Pueblos
inhabitants of presidios and pueblos were given title to their lands, if they met development criteria, but not given title of water. water belong entire community not an individual
-
Water law Under Spanish Rule
- called Pueblo Right- water rights of the pueblos were superior to any other right.
- pueblos rights were inferior to pueblo rights
-
The Mexican Era
- 1821 to 1848
- Mexico achieved independence from spain in 1821.
- same water law as the spanish
- land ended up in the hands of the wealthy Mexican families.
-
The American Era
- 1948- Present
- 1846 US and Mexico went to war
- American victory
- Treaty of Guadalupe Hidalgo 1848
-
American attitude to water
Like Spanish/ Mexican system
- looked at water as a source of wealth.
- legal traditions that sanctioned stream diversions
-
Attitude to water
Different from Spanish Mexican system:
- stressed individual rights rather than community rights.
- minimal government interference in water matters.
-
California adopted what law in 1850
California adopted the common law of England which specifies riparian rights
-
Riparian Rights
- Derived from ownership of a piece of land adjacent to lake or stream
- The rights are bought and sold with the land
- must be used for a beneficial purposes.
-
appropriative water rights
- based on practice of miner during the gold rush.
- "first in time=first in right
- applied to water diverters.
- the first person to appropriate is senior water right
- the 2nd and 3rd have junior water rights.
- they can purchase tye are able to be bought and sold.
- rule: they must be used for beneficial use .
- use it or lose it.
-
Prior to the 1848 Treaty of Guadalupe
- Pueblo rights
- San diego and Los Angeles are the only pueblos to exercise pueblos water rights in court.
- Pueblo right are superior rights from riparian and appropriative rights.
-
Homestead act of 1862
- 1862
- Offered 160 acres of land to anyone willing to clear, improve and reside o it.
- if you were married you got more land.
-
appropriative rights continue
- can be sold or transferred separately from the land.
- first person to make a claim and put the water to beneficial use has superior rights.
-
Lawsuit regarding water rights
- Lux vs. Haggin
- Bakersfield
- they were big land owners.
- Henry Miller(Lux partner) associated bringing boats across the land. They were Riparian.
- James Haggin bought a lot of land.
- Haggin originally won, the higher courts decided that Lux and Miller won.
-
The California Doctrine
- 1886 Lux v. Haggin
- riparian rights prevailed in all private land
- appropriator could possess a right superior to a riparian only if the appropriator begun using the water before.
- timing decided who prevailed in court
-
Federal Reserved Rights
- another lawsuit
- Winters (represented Farmer and homestead vs. United State (Indians)
- the reservation had a superior right
- Reservation rights are more superior than any other.
-
Who doesn't have groundwater laws
California and Texas
-
Overlying Rights
- all property owners above a common aquifer posses a mutual right to the reasonable and beneficial use of a groundwater resource on land overlying the aquifer from where the water is taken.
- proper overlying use taking precedence over all non-overlying uses.
-
Appropriative rights
appropriative users are entitled to use the surplus water available after the overlying users rights are satisfied.
-
County of Origin Statute 1931
- You can't divert the county water until the county needs are met and used first.
- Exempt that was the Owens Valley and Mono Lake.
- If this law never would of been placed the Northerners would not agree with the aqueduct.
-
The Public Trust Doctrine
- 1983
- very old Roman law.
- Law states any body of water that has fish, recreation, ecology and aesthetic, to the public
- Protect the public, no person has a vested right that when the public trust has interest in it.
