Stormwater BMPs and the Thanksgiving Feast
Thanksgiving is a time for family and feasting, but when the meal is over are you properly disposing your FOG waste? Fats, oils, and grease (FOG) are often disposed of improperly. FOG comes from meats, butter, lard, food scraps, sauces dressings, dairy products, and cooking oil. Some methods of improper disposal may seem obvious as a bad choice, such as dumping used cooking oil down the storm drain, but even washing greasy residues down the kitchen drain can create problems.
Improper disposal of FOG can lead to property damage, health hazards, and environmental problems. Pipes may become blocked by FOG poured down the drain, even if diluted with hot, soapy water. Grease transforms back into a solid as it cools. As FOG builds up in the wastewater system, catching on items leading to "fatbergs" that create blockages. One famous example being the 15-ton London fatberg, which damaged the sewer and took 6 weeks to repair.
FOG can run into a nearby stream or river, which affects our drinking water. Oils pollute streams and creeks by forming a film on the water surface, which prevents oxygenation for aquatic life. Polluted stormwater runoff can lead to excessive and costly maintenance and cleanup.
