Overall CalEnviroScreen scores are calculated from the scores for two groups of indicators: Pollution Burden and Population Characteristics.

\n\n

 

\n\n

This map shows the combined Pollution Burden scores, which is made up of indicators from the Exposures and Environmental Effects components of the CalEnviroScreen model. Pollution burden represents the potential exposures to pollutants and the adverse environmental conditions caused by pollution.

\n\n

\nWhat is ozone?
\n\n

Ozone is the main ingredient of smog. At ground level, ozone is formed when pollutants chemically react in the presence of sunlight. The main sources of ozone are trucks, cars, planes, trains, factories, farms, construction, and dry cleaners.

\n\n

 

\n\n

Ozone can irritate the lungs, cause inflammation, and make chronic illnesses worse, even at low levels of exposure. Children and the elderly are sensitive to the effects of ozone. Ozone levels are highest in the afternoon and on hot days. People who spend a lot of time outdoors may also be affected by ozone.

\n\n

 

\n\n

\nWhat is PM2.5?
\n\n

Particulate matter or PM2.5 is very small airborne particle pollution (less than 2.5 micrometers), which is less than the thickness of a human hair. PM2.5 is a mixture of particles that can include organic chemicals, dust, soot and metals.

\n\n

 

\n\n

These particles can come from cars and trucks, factories, wood burning, and other activities. They can travel deep into the lungs and cause various health problems including heart and lung disease because they are so small.

\n\n

 
\n

\n\n

Children, the elderly, and people suffering from heart or lung disease, asthma, or chronic illness are most sensitive to the effects of PM2.5 exposure.

\n\n

 

\n\n

\nWhat is diesel particulate matter?
\n\n

Exhaust from trucks, buses, trains, ships and other equipment with diesel engines contains a mixture of gases and solid particles. These solid particles are known as diesel particulate matter (diesel PM). Diesel PM contains hundreds of different chemicals. Many of these are harmful to health. The highest levels of diesel PM are near ports, rail yards and freeways.

\n\n

 

\n\n

The particles in diesel PM can reach deep into the lung, where they can contribute to health problems including eye, throat and nose irritation, heart and lung disease, and lung cancer. Children and the elderly are most sensitive to the effects of diesel PM.

\n\n

\nWhat are drinking water contaminants?
\n\n

Most drinking water in California meets health standards. However, drinking water sometimes becomes contaminated with chemicals or bacteria above the standards. Both natural and human sources can contaminate drinking water. Natural sources include rocks, soil, wildlife and fires. Human sources include factories, sewage, and runoff from farms.

\n\n

 

\n\n

One common contaminant, arsenic, occurs naturally in some rocks and soil and is often found in groundwater in California. It can cause cancer. Nitrate from fertilizer or manure can leach into groundwater and contaminate wells. Nitrate can cause a blood disorder in infants called blue baby syndrome.

\n\n

\nWhat are pesticides?
\n\n

Pesticides are chemicals used to control insects, weeds and plant diseases. Over 1,000 pesticides are registered for use in California. They are applied to fields by air, by farm machinery, or by workers on the ground.

\n\n

 

\n\n

Farmworker families and other people who live near fields can be exposed to pesticides, both outdoors and inside homes. Exposure to high levels of some pesticides can cause illness right away or conditions such as birth defects or cancer later in life.

\nWhat are toxic releases?
\n\n

Facilities that make or use toxic chemicals can release these chemicals into the air. Information is available on the amount of chemicals released for over 500 chemicals for large facilities in the United States.

\n\n

 

\n\n

These chemicals are sometimes detected in the air of communities nearby. People living near facilities may breathe contaminated air regularly or if contaminants are released during an accident.

\nWhat is traffic density?
\n\n

California has the biggest network of freeways in the country. Its cities are known for heavy traffic. Traffic density is a measure of the number of vehicles on the roads in an area.

\n\n

 

\n\n

While California has strict vehicle-emissions standards, exhaust from cars and trucks is the main source of air pollution in much of the state. Major roads and highways can bring air pollutants and noise into nearby neighborhoods. Children who live or go to schools near busy roads have higher rates of asthma than children in areas farther from roads.

\nWhat are Cleanup Sites?
\n\n

Cleanup sites are places that are contaminated with hazardous chemicals and require clean up by the property owners or government. Chemicals at cleanup sites can move through the air or groundwater. People living near these sites have a greater potential to be exposed to chemicals from the sites than people living further away.

\n\n

 

\n\n

Some studies have shown that neighborhoods with cleanup sites are generally poorer and have more people of color than other neighborhoods. The land may take many years or decades to clean up, reducing possible benefits to the community.

\nWhat are Groundwater Threats?
\n\n

Hazardous chemicals are often stored in containers on land or in underground storage tanks. Leaks from tanks can contaminate soil and groundwater. Common soil and groundwater pollutants include gasoline and diesel fuels at gas stations, as well as solvents, heavy metals and pesticides.

\n\n

 

\n\n

Leaking tanks can affect drinking water and expose people to contaminated soil and air. The land and groundwater may take many years or decades to clean up.

What is Hazardous Waste?

\n\n

 

\n\n

Hazardous waste contains chemicals that may be harmful to health. Only certain facilities are allowed to treat, store or dispose of this type of waste. Hazardous waste can range from used automotive oil to highly toxic waste materials produced by factories and businesses. Hazardous waste is transported from businesses that generate waste to permitted facilities for recycling, treatment, storage or disposal.

\n
\n\n

 

\n\n

Studies have found that hazardous waste facilities are often located near poor neighborhoods and communities of color.

\n\n

 

\n\n

Hazardous waste facilities often are cause for concerns about effects on health and the environment in the communities where they operate.

\nWhat are Impaired Water Bodies?
\n\n

Water bodies like streams, rivers or lakes are used for recreation and fishing or may provide water for drinking or irrigation. When water bodies are contaminated by pollutants, they are considered impaired. These impairments can harm wildlife habitats and prevent recreational and other uses of the water body.

\n\n

 

\n\n

Certain groups such as tribal or low income communities may depend on the fish and wildlife in nearby water bodies more than the general public.

\nWhat is Solid Waste ?
\n\n

Solid waste facilities are places where household garbage and similar kinds of waste are collected, processed, or stored. These include landfills and composting or recycling facilities. The waste material may come from homes, factories or businesses. Most of these operations require permits.
\n 

\n\n

Regulated facilities as well as illegal sites that do not comply with the law can harm the environment and potentially expose people to hazardous substances. Solid waste facilities can also raise concern in a community about odors, insect pests, vermin, and truck traffic. The communities near solid waste facilities are usually home to poor and minority residents.
