Groundwater

Rivers/Watersheds
Wisconsin Groundwater Facts




70% of WI residents rely on groundwater.
Over 800,000 private wells in WI.
Typical private wells yield water a few years
to a few decades old.
Municipal wells are required to have water
tests, individual well testing is optional.
Groundwater Monitoring

Drinking water analyses



Basic package includes nitrate, pH,
bacteria, hardness, alkalinity, chloride
Metals package
Pesticides
Groundwater Monitoring Options

Individual resident samples



Individuals submit samples
Interpretation guide provided with
results
Assistance over telephone available
Groundwater Monitoring Options

Community drinking water programs



Provides a community/regional view of
groundwater
Coordinated between local representative,
WEAL Lab, and UWEX Groundwater
Educator
Includes a community groundwater
education program to better understand
the analytical results
Community Drinking Water Programs


County, Township, Watershed, Lake Assoc.
Benefits




Determine safety of drinking water supply and
learn about treatment methods
Increased understanding of groundwater and the
connection to the landscape
Better indicator of community’s groundwater
quality
People are informed on ways to protect water
resources
Community Drinking Water Programs
Lake Monitoring



Determine current
conditions and long-term
trends
Individual residents/lake
associations
As partners with CWSE
in conjunction with lake
assessments
Lake Monitoring – Overturn Program





Samples are collected when the lake is
“mixed” (Spring and Fall Overturn)
Individuals collect samples from deep
hole of lake
Samples are prepared according to
instructions and shipped on ice to the
lab
Samples are analyzed in the lab for
nutrients, minerals, contaminants
Data are stored in a database and
graphed twice/year
River/Watershed Monitoring

Monitoring rivers is MUCH trickier!





More rules/quality control/ quality assurance



Moving water
Varying quantities of water
Water quality changes over a given storm
Affected by a variety of adjacent land uses
Need to know the amount of water
Need to know the amount of precipitation
Sample collection is relatively easy –
sampling design is not
River/Watershed Monitoring





CWSE monitoring builds on WAV
monitoring
Lab data can help provide answers to
observations made with WAV monitoring
Analyses include more than what could be
measured with a field kit
Lab data are more accurate because of the
methods of analysis and the quality control
CWSE can provide assistance with
sampling design/site selection
River/Watershed Monitoring
Used to Assess




Current conditions
Long-term trends
Affects of particular land
use activities
Who collects the samples?

River Monitoring Program

Baseflow monitoring is
recommended for measuring
long-term trends



Rivers are at low flow so water
quality can be easily compared
over a long period of time
Standard package include
suspended sediment, nutrients,
and chloride
Additional analyses may
include metals (urban) or
pesticides (rural)
Quality Control/Assurance
