Protecting
Your Well
You can protect your water supply by carefully managing activities near the water source. For households using a domestic well, this includes keeping contaminants away from sinkholes and the well itself. Hazardous chemicals also should be kept out of septic systems.

cracked, corroded, or damaged well casing.

Private
Water Supplies The
testing frequencies in this fact sheet are general guidelines. Test more often
if you suspect there is a problem with the quality of your drinking water. Once
each year test for coliform bacteria, nitrate, pH and TDS. It is best to test
for these contaminants during the spring or summer following a rainy period.
These tests should also be conducted after repairing or replacing an old well or
pipes, and after installing a new well or pump. Every
3 years test for radon, mercury,
sulfate, chloride, iron, manganese, lead, hardness and corrosion index. If
a new baby is expected in the household, test for nitrate in the early months of
a pregnancy, before bringing an infant home, and again during the first 6 months
of the baby's life. Special
Situations Where
you live, or what you are living next to, can sometimes affect the quality of
your well water. If someone in your family becomes ill, or the taste, odor or
color of your water changes, your water supply may be contaminated. If
your well is in an area of intensive agricultural use, test for pesticides
commonly used in the area, coliform bacteria, nitrate, pH and TDS. If
you live near a coal or other mining operation, test for iron, manganese,
aluminum, pH and corrosion index. If
your well is near a gas drilling operation, test for chloride, sodium, barium
and strontium. If
your water smells like gasoline or fuel oil, and your well is located near an
operational or abandoned gas station or buried fuel storage tanks, test for fuel
components or VOCs. If
your well is near a dump, junkyard, landfill, factory, or dry cleaning
operation, test for VOCs (such as gasoline components and cleaning solvents) pH,
TDS, chloride, sulfate and metals. If
your well is near seawater, a road salt storage site, or a heavily salted
roadway and you notice the water tastes salty or signs of corrosion appear on
pipes, test for chloride, TDS and sodium. If you live in New Jersey, click here for specific information regarding drinking water wells.
