This event is limited to the first 18 entries Background Teams will receive a 250-mL sample of water that was obtained from a standing body of water adjacent to an abandoned automobile junkyard. EPA officials have counted over 740 hulks of old automobiles and trucks and several dozen piles of various auto parts, some being over 40 years old. Most are essentially unrecognizable due to crushing and or decay. The standing pond, no doubt, contains toxic metal contamination from the years of weather and corrosion effects on the vehicles and various piles of auto parts found in the yard. The standing water is attributed to run-off from natural rainfall and the essentially impenetrable nature of the clay based soil in the area of the pond.
Objectives Determine what contamination exists in the water using standard laboratory procedures.
Establish the level of contamination present in a quantitative fashion. Use any standard method for determination of this reporting findings in standard units. This events must be completed by a team of 2 or 3 students. All sources of information must be identified clearly. Any conclusions you form must be based upon your own experimental data.
