What is an Aquifer?
An aquifer is an underground layer of rock or sediment that stores and transmits groundwater in usable amounts.

Name one thing the EPA monitors in ground water?
Nitrates, Bacteria, Hardness, Iron, TDS, Copper, ect.
100
Name one remediation method.
Water softener, reverse osmosis, distillation, casing requirements in well construction, ect.

Define "Casing" and "Screen" in a well.
Casing is the metal tubular part of a well that inhibits infiltration of material or water it passes through.
Screen is where water enters the well

What types of aquifers have high porosity and high conductivity? What have low?
Sand & Gravel Aquifers, Igneous or metamorphic

What is a primary standard according to the EPA?
It is a contaminant that has immanent health implications and is closely monitored with standards set by the EPA.

You have a water hardness of 0ppm, what should the home owner do?
The homeowner should turn down the water softener as it is taking too much carbonates out of the water.

What counties is there arsenic contamination an issue in our state?
Outagamie and Winnebago

What is the term for a layer that creates an impermeable for water as it moves downward through the ground?
Confining layer

Why are nitrates so important to monitor?
Infants can become seriously ill and, if untreated, may die. Symptoms include shortness of breath and blue-baby syndrome.
300
What remediation would you recommend to a persons home if they had a Nitrate level of 25ppm?
Reverse Osmosis system should be installed as this exceeds the EPA MCL for nitrates.
300
What geologic layer is responsible for leaching arsenic into ground water?
The SCH arsenic horizon, location of the Sinnipee Group, and St. Peter Sandstone contact.

This part of your body has more bacteria living on it than there are people on Earth.
Human Skin

What aquifer do we have in Central Wisconsin? How was it created?
Sand & Gravel aquifer referred to as surficial aquifer. It was created by glacial melt and setling of sorted particles with glacial Lake Wisconsin.
400
You have a measured hardness of 200ppm. Let me about the level of hardness. What is the ideal hardness in groundwater used by a home?
This is water is hard, edging on very hard. An ideal range of hardness is 30-60ppm.
400
Why is distillation not frequently recommended as a remediation method?
Distillation is recommended in specific, limited situations—it’s very effective, but impractical for most whole-house needs.
400
What is the indicator when drilling a well that there could be issues with arsenic contamination?
Black sandstone being created by the SCH layer.

What was the first job Mr. Hackett had in high school?
Paintball Referee

Give an example of rock layers in North East Wisconsin discussed in class.
SCH Arsenic Horizon, Black Sandstone, Sinnipee Group, Cambrian Sandstone, Prarie du Chien Group, Maquiketa Shale,

Explain why there are elevated numbers of Nitrates in Portage county.
High levels of agriculture in sandy soil which requires more fertilizers. Having a sand / gravel aquifer that water moves quickly through

In the Arsenic Advisory area in Wisconsin, what remediation was suggested to help mitigate arsenic infiltration into personal well water?
They have a minimum "casing" requirement for well construction to prevent infiltration from the SCH horizon that is closer to the surface.
500
Which well runs the greatest risk of Arsenic contamination? Why?
Well A, as it is drawing from an aquifer that is directly adjacent to the SCH horizon which is know for leaching arsenic into ground water.
