The City of Alexandria will hold a Household Hazardous Materials Collection Day Saturday at the School Board Maintenance Facility at 3540 Wheeler Ave.

City officials have urged residents to dispose safely of unwanted toxic, corrosive or flammable household material on Collection Day.

Officials are seeking to avert improper handling of substances that, if not handled properly, could harm the environment and pose a threat to public health.

A brochure sent recently to city residents identifies the kinds of hazardous materials that will be accepted on Collection Day.

It urges Alexandria residents to check sheds, basements and other storage areas for such materials as insecticides, herbicides, pesticides, fertilizers, paint thinners, solvents, swimming pool chemicals, fuels, darkroom chemicals, chemistry sets and oil-based paints and stains.

City residents may turn in materials for disposal between 9 a.m. and 3 p.m. at the facility.

Substances must not be mixed and should be brought in their original containers. Damaged containers should be carried in plastic bags.

Persons with more than five gallons of liquid or more than 75 pounds of solid waste to dump must alert Collection Day staff in advance by calling 751-5130.

Once collected at the School Board Maintenance Facility, a federally licensed contractor hired by the city will be responsible for neutralizing, recycling, incinerating or disposing of the material.

Some types of hazardous materials require especially careful handling and will not be taken at the site. Materials such as radioactives, asbestos, latex paint, major appliances, explosives, compressed gas cylinders, shock sensitive materials, dioxins and kepones will not be accepted.

Commercial, industrial and medical waste also will be turned away, as well as substances in unmarked containers that are hard to identify.

To obtain a free copy of the brochure called Community Clean-Up: Household Hazardous Materials, or for information on how to dispose of materials that will not be accepted at the site, residents can contact the Citizens Assistance Office at 838-4800.
