About Pollution from Industries and Other Businesses

Factories, refineries, dry cleaners, and other businesses can pollute the air we breathe, water we depend on, and land around us. That pollution can have a big impact on the lives of people who live, work, play, and learn nearby. The impact can be anything from a mild headache to contaminated groundwater that may put us at risk during future droughts. There are laws to control how much businesses can pollute the area. Local, state, and federal agencies exist to help enforce laws that describe how much pollution is allowed. However, these agencies need your help to be their eyes and ears on the ground in your community.

Air Pollution from Factories and Other Businesses

We all deserve to breathe clean, healthy air. Most air pollution in Los Angeles County comes from cars, trucks, and other vehicles but factories and other businesses also add to air pollution. When people live, work, play, and learn near polluting businesses it can create health problems including ear, nose, and throat irritation, headaches, asthma attacks, and an even greater risk of developing cancer.

The South Coast Air Quality Management District (SCAQMD) sets rules about how much and what kind of chemicals and other pollutants a business can put into the air. The SCAQMD permits and inspects businesses that contaminate the air to make sure that they are following the rules. Please visit their website for more information or to report a problem with outdoor air pollution at the SCAQMD website or call 1-800-CUT-SMOG.

Water Contamination

Everyone deserves clean, safe water and we must protect our water supply to make sure that our communities in Los Angeles County will have enough water for future generations. Water can become polluted in many ways. Sometimes businesses dump chemicals or hazardous waste on to the ground or in the sewer. Those chemicals can reach the groundwater and cause contamination of water that we might need in the future.

We all deserve to live in clean, healthy communities. Chemicals can travel in the air and end up in nearby soil or be dumped on to the ground directly. Chemicals that contaminate the soil around where we live, work, play, and learn can cause health problems, depending on the type of contamination. Different types of contamination can cause developmental disorders in children and greater chance of certain cancers.

Past soil contamination can also be a cause for what are called brownfields, which are abandoned and possibly contaminated properties. Brownfields can be unattractive areas in your community and prevent the redevelopment of a neighborhood. The California Department of Toxic Substances Control (DTSC) is responsible for overseeing cleanups at places with contaminated soils. For questions, call DTSC at 1-800-728-6942.
