Cryptosporidium Laboratories Acceptable for Monitoring to Comply with the
Long Term 2 Enhanced Surface Water Treatment Rule
The following list of laboratories may be used by public water systems (PWSs) complying with the Long Term 2 Enhanced Surface
Water Treatment Rule. This list generally will be updated via written request from personnel with a state or EPA regional
laboratory certification program. Please use the links below to access state websites for the laboratory's current certification
status and contact information. PWSs should be aware that their states may establish requirements that are more stringent than
EPA's regulations; state requirements would take precedence.

1 On March 29, 2016, Pennsylvania's Department of Environmental Protection (PA DEP) suspended its accreditation of Analytical Services, Inc.
(see Suspension Notice for the announcement). New Hampshire's Environmental Laboratory Accreditation Program (NH ELAP), the entity that
originally assessed and accredited ASI, and whose assessment was the basis for PA DEP's secondary accreditation, led on-site audits of ASI in April
and May 2016. NH ELAP identified required corrective actions in a report issued to the laboratory in late June 2016. In August 2016, NH ELAP
affirmed that ASI remains accredited by NH based on ASI's progress in implementing and documenting corrective actions.
