As one of the leading lead laboratories in the nation, EHS analyzes water samples for lead content from school districts and child care facilities across the country.

 Nearly 56 million Americans, including 53 million children, spend their days in schools. School officials need to know if the drinking water students, teachers, and staff consume contains elevated levels of lead because exposure to lead can cause serious health problems, particularly for young children.

Although public water systems that supply water to most schools may meet EPA’s lead standards, lead can still get into school drinking water.  As water moves through a school’s plumbing system, lead can leach into the drinking water from mental development plumbing materials and fixtures that contain lead.  Testing is the ONLY WAY for schools to know if there are elevated levels of lead in a facility’s drinking water.

Potential Sources of Lead In Drinking Water:

  • Lead solder
  • Lead pipe and pipe fittings
  • Fixtures, valves, meters and other system components containing brass
  • Sediments


National Ground Water Association recommends well owners test the water:

  • Annually for bacteria, nitrates/nitrites, and any contaminants of local concern
  • More frequently than once a year if there is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap or a new contamination source
  • If family members or houseguests have recurrent incidents of gastrointestinal illness
  • If an infant is living in the home
  • To monitor the efficiency and performance of home water treatment equipment.


A “conventional loan” will only require a Coliform Bacteria test be performed. A concerned buyer may want other tests done on the water such as those listed below for FHA and VA loans but they are not required.

For FHA and VA loans, the following tests are normally required: Coliform Bacteria, Lead, Nitrates, Nitrites, and Turbidity.
