CEC Projects

Pall Corporation, Ann Arbor, MI. CEC assisted Pall with the development and validation of the Envirochek™ and Envirochek HV™ capsules for approval by the U.S. Environmental Protection Agency (USEPA) for Methods 1622/1623 for Cryptosporidium/Giardia testing. CEC developed a new method using the Envirochek HV for high-volume finished water samples, and has adapted the Pall capsule technology for high volume total coliform monitoring.

UK Water Industry Research, London. CEC directed round-robin trials of cell culture methods for assessing the infectivity of Cryptosporidium oocysts in water and determining the sensitivity of infectious oocysts to UV treatment.

BTF, Ltd., Sydney, Australia. CEC conducted studies to validate EasySeed™ requiring USEPA approval for Methods 1622 and 1623 for analysis of water samples for Giardia cysts and Cryptosporidium oocysts.

United Kingdom Drinking Water Inspectorate (DWI), London. CEC prepared a feasibility report for the DWI to assess whether a Cryptosporidium monitoring program for finished water could be conducted on a continuous basis, and assisted in development of methods to carry out the program. The DWI established such a program and has been conducting finished drinking water monitoring of surface supplies since 1999.

IDEXX, Westbrook, ME. CEC validated the FiltaMax™ filter for inclusion as an approved product in USEPA Methods 1622 and 1623. Bukhari et al., 1998 (PDF).

American Water Works Association Research Foundation (AwwaRF). CEC characterized phages other than MS2 for full-scale UV reactor validation, allowing lower Reduction Equivalent Dose (RED) bias in UV dose requirements.

American Water Works Association Research Foundation (AwwaRF). CEC has developed improved methods for total coliform sampling and analysis incorporating high volume sampling with defined substrate technology.
