When requesting VOCs analysis, the following tests may be performed: vinyl chloride, trans-1,2-dichloroethene, methyl-t-butyl ether (MtBE), cis-1,2-dichloroethene, benzene, trichloroethene, naphthalene and many others. For the full list of VOC analytes, see the SPHL webpage. VOC sample collection must be conducted by DHSS staff.

The SPHL is able to analyze water samples from private drinking water sources. Private water sources include private groundwater wells, cisterns, and larger private water systems that serve more than one residence.
- Private ground water wells usually supply water to an individual residence.
- Private water systems are those that serve no more than 25 people at least 60 days of the year and have no more than 15 service connections. Each building serviced by the same private water system is considered to be a service connection for that system. Most private water systems use ground water wells.
