Description:
This event will focus on fresh water (e.g., residential, industrial or natural), the identified pages of The Clean Water Act (1972 & 1977), wastewater operator’s certification manual (Indiana March
2018 revision) and its applications, various testing of particular analytes using standardized curves (either interpreted or created), stabilization ponds, and introduction to the National Pretreatment Program.
The competition will consist of a series of tasks that may include hands-on activities, questions about a topic, interpretation of experimental data (e.g., graphs, diagrams), generating a standardized curve using data provided, using a given standardized curve to determine unknowns, or observation of an
experiment set up & running.
Materials:
Teams should bring pencils for graphing and answering questions, a ruler (12-15 in.) for best fit line approximation, two stand-alone non-programmable, non-graphing calculators, and one three-ring binder of any size containing information in any form and from any source attached using the available rings. Sheet protectors are permitted. Participants may not remove information or pages during the event.
Participants must wear goggles, an apron or a lab coat and have skin covered from the neck down to the
wrist and toes. Gloves are optional, but if the host requires a specific type, they will notify teams. Pants should be loose fitting; if the host has more specific guidelines, they will notify teams in advance of the tournament. Shoulder length or longer hair must be tied back. Participants removing safety clothing/goggles or unsafely handling materials or equipment will be penalized or disqualified.
Scoring:
Highest score wins.
The score will be comprised of approximately 60% of the points for wet chemistry tasks/making & interpreting standardized curves, 20% of the points for equations and interpreting data, and approximately 20% of the points for questions on the reference material.
Common Mistakes:
None
Recommendations:
