List the roles plants play in a healthy aquatic ecosystem. ANSWER- -producing
oxygen
-preventing shoreline erosion
-lessening excess nutrients during growing season
-stabilizing lake bottom
-providing food and habitat for fish, waterfowl, and other aquatic animals
List ways that excessive plant growth can adversely affect the ecology and uses of
a water body. ANSWER- -harm ecology of aquatic ecosystem
-curtail or prevent recreational water uses (e.g. fishing, boating, swimming)
-impart tastes or odors to drinking water
-hamper water treatment operations
-adversely affect aesthetics, resort trade, and waterfront property values
-produce toxins that harm animals drinking the water
Describe the general growth habits of, means of dispersal and potential problems
caused by: Emergent aquatic plants ANSWER- -*growth habits*: rooted in
shallow water, most growth above water
-*means of dispersal*: underground root systems
-*potential problems*: very dense and may exclude recreational pursuits like
boating, fishing, and swimming. Purple loosestrife is an example of a problem
species.

Describe how to properly rinse pesticide containers and list the benefits of doing
so. ANSWER- -Triple Rinse - do this as soon as the containers are empty
-Process: 1) fill with water to 10-20% capacity 2) securely replace cap 3) shake
and rinse 4) drain container into sprayer 5) repeat 3 times
Describe the 2 types of incompatibility that can happen when mixing pesticides
and explain how to avoid them. ANSWER- -*physical incompatibility*: easy to
see, solids settle out of mixture or mixture separates into layers; compatibility
agents may be added to rejuvenate mixture, but otherwise treat it as pesticide waste
-*chemical*: not listed
-avoid incompatibility by mixing a small jar to see if components are compatible.
Know the Law: Should you fill or clean pesticide equipment where pesticide might
enter a well or surface water or where rising waters could flood the filling/cleaning
site? ANSWER- No.
Know the Law: Should you comply with spill containment surface requirements if
you mix, load, or transfer more than 1,500 pounds of active ingredient at one site
in a calendar year or if you do so within 100 feet of a well or surface water?
ANSWER- Yes.
Know the Law: May you ever mix or load pesticides within 8 feet of a well or
surface water? ANSWER- No.
Know the Law: Should you protect your water supply from contamination by using
an air gap or an antisiphoning device? ANSWER- Yes.

Know the Law: Can you use rinsates in a future mix provided the pesticide in the
rinsate is labeled for the site and the final mix does not exceed label rates?
ANSWER- Yes.
Know the Law: Which pesticide containers may be recycled or disposed of in a
landfill? ANSWER- Only those that have been triple rinsed or the equivalent.
Define when pesticide becomes waste and who is responsible for disposing of it.
ANSWER- when it has...
-served its originally intended purpose OR
-you intend to discard
the person responsible for disposing of it is the one who creates the waste
List steps you can take to reduce the amount of pesticide waste you generate.
ANSWER- -purchase only as much pesticide as you need
-date products, use older ones first
-store different pesticides separately (volatile vs. rest, liquid beneath solids)
-place leaky containers in other containers
-keep pesticides in original label with legible label
-triple rinse containers and use rinsate
-keep rinse water and rinsate separate
-wear chemical-resistant apron or spray suit when mixing/loading
Compare and contrast solid vs. hazardous waste. ANSWER- -*solid*: anything
not classified as hazardous waste; can be solid, liquid, or contained gas; "trash";
any discarded or abandoned materials
-*hazardous*: classification found on SDS sheet

Specify which type of pesticide waste you may dispose of in a sanitary landfill.
ANSWER- -solid waste, non-hazardous
Explain why landfill operators may refuse to accept certain pesticide wastes.
ANSWER- -must first consult with landfill operator to see which pesticide waste,
if any, are accepted.
-landfills not required by law to accept pesticide wastes
-if wastes are found to cause environmental or human health problems, landfill
operator shares legal liability with landfill customers and may be reluctant to
accept pesticide waste
Describe your options for disposing of pesticide containers and other solid wastes.
ANSWER- (in order of most to least preferred)...
-return them to dealer for reuse or refilling
-recycle them
-bring them to a Wisconsin Clean Sweep program
-dispose of them in approved landfill
Explain how to deal with leftover liquid pesticides, unwanted, banned or
unidentified pesticides, and other pesticide solid waste. ANSWER- -*liquid*:
must be managed as hazardous waste; sanitary landfills won't accept any liquids;
small amounts of some liquids can be solidified and taken to landfills (don't do this
to haz wastes unless authorized); can dispose via commercial haz waste hauler
-*unwanted, banned, or unidentified*: best option is to use Clean Sweep program
or private haz waste hauler; never mix chems together for disposal; treat spills and
the absorbent material/soil as waste
-*other solid waste*: clothes that have been contaminated are to be treated as solid
waste if pesticides aren't listed as hazardous
