FOR DROUGHT MITIGATION AND
SUSTAINABLE AGRICULTURAL PRODUCTION
Wellhead Protection
 Missouri had new well installation regulations go




into affect March 1995
This gave standards for well location and well
construction.
Many older wells were grandfathered in
All new wells must meet the new standards
Approximately 6,000 new wells drilled every year.


Serves approximately 890,000 citizens
86% of private wells are drilled.
 It is important to understand the geology of the state
to have an idea of how much groundwater is
available.
 The availability of good quality water does dictate
number of businesses, individuals, etc. that can
locate in an area.
Emergency Water Source

 Over 1800 wells installed for either livestock or
irrigation.
 Average cost on livestock water supply
 Average depth was 410 feet

Well construction basics:
 Well casing – 6 inches diameter
 Casing joints – water tight joints
 Vertical extension – well casing shall extend at least
one foot about the finished surface grade (2 feet
above maximum known floodwater elevation if in a
flood plain)
 Depth of casing – to such depth as may be necessary
to exclude contaminants
 Grouting – ensure that the annular space is sealed
and that the casing does not leak.
Review state regulations on proper wellhead
design and installation
Should be 1 foot
above the surface
casing depth
will depend
on soils and
location
Well Construction basics:
 Connections (above grade) – shall be 1 foot above
finished grade and constructed to exclude dirt and
other foreign matter from entering the well.
 Every well shall be maintained by the owner in a
condition where it will conserve and protect the
groundwater resources and where it will not be a
source or channel of contamination or pollution to
the water supply of the well or any aquifer.
Well Construction Basics:
 Construction requirements are based on well yield,
use of well, and the region in which your well is
located. And vary throughout the state according to
the geology of the region.
 Always use a permitted driller when drilling or
repairing a well.
Wellhead Protection
 Irrigation wells
 200 feet from sewer lines, septic tanks, lateral fields, feed lots,
barnyards, fuel storage, fertilizer and pesticide storage.
 200 feet from well producing potable water
 15 feet or more from overhead electrical distribution line

Fuel, fertilizer and pesticide tanks up to 1,000 gallons are allowed
at well while irrigating and chemigating but must be removed from
well site when not in use
Wellhead protection
New or Reconditioned?
 Depending on condition of an older well it may be
cost effective to recondition it instead of drilling a
new well.
 Check for depth, casing condition, wellhead
protection, gpm flow, location.
 If old well can’t be properly reconditioned it should
be properly plugged.
We still use the old well as a back up.
Plugging Abandoned Wells
 Any well in a state of disrepair, obtaining
groundwater is impractical and which has not been
in use for 2 years or more
 Permanent Abandonment of Wells
