The contaminated case of the cooking contest (galactic academy of science) - Contaminated Runways - Code7700



Water contamination is the term used to describe hazardous materials of any kind that are polluting a source of water. This could include both biological and chemical substances, and the water source may be ponds, lakes, seas, oceans, or reservoirs used for drinking and bathing by humans. The most common types of water contamination are chemical runoff from homes and businesses and sometimes human or animal waste materials.

In industrialized nations, water contamination is much less common than in third world and developing countries. That’s because sophisticated water purification systems are in place to clean waste materials from the water, disinfect it using chemicals, and then purify it so that it is safe for consumption. Areas that do not have these technologies may encounter contaminated water due to animal wastes entering the water supply or household chemicals running from the ground into underground wells.

Most sources of water contamination in the industrialized world come from chemical pollution, either from the dumping of chemicals onto the ground or down drains, or through accidental spills. Oil spills, for instance, may occur from wells or ships and can contaminate water for miles from the spill site. Industrial plants may also dump wastes into water, although this is less common due to tighter government regulations regarding disposing of hazardous materials.

The goal at each petroleum spill site is to remove the spilled petroleum product from the soil in the most efficient and safe manner in order that the soil may be returned to a reusable product. When complete removal is not possible, practical, or cost effective, the objective is to remediate the contaminated media to concentration levels which will protect groundwater, human health and the environment.

The Petroleum-Contaminated Soil Guidance Policy is intended to provide direction on the handling, disposal and/or reuse of non-hazardous petroleum-contaminated soils. The reuse or disposal options for excavated soils vary depending on the level of treatment provided consistent with protecting the public health and the environment. While this document does not establish standards, it is intended as guidance in determining whether soils have been contaminated to levels which require investigation and remediation.

That isn't to say we are unarmed in this battle, pilots do have some tools at their disposal. But there is a lot of judgement involved. You can develop that judgement with a little research.

[ Aeronautical Information Manual , Pilot/Controller Glossary] CONTAMINATED RUNWAY− A runway is considered contaminated whenever standing water, ice, snow, slush, frost in any form, heavy rubber, or other substances are present. A runway is contaminated with respect to rubber deposits or other friction-degrading substances when the average friction value for any 500-foot segment of the runway within the ALD fails below the recommended minimum friction level and the average friction value in the adjacent 500-foot segments falls below the maintenance planning friction level.

[ AC 91-79 , appendix 4, ¶10.b.(2)] NOTE: The FAA has taken the position that a runway does not need to be reflective to be considered wet. If a runway is contaminated or not dry, that runway is considered wet.
