ITT has announced that its WTW and OI Analytical instrument brands offer a range of measurement options for the detection of the carcinogenic hexavalent chromium in drinking-water supplies.

ITT Analytics’ range of simple and convenient screening tests will assist US water utilities to achieve fast and accurate measurement of the cancer-causing element in water while meeting EPA guidelines.

The US Department of Health and Human Services, the International Agency for Research on Cancer and the US Environmental Protection Agency (EPA) have determined that chromium VI is a carcinogen.

Humans and animals exposed to chromium VI in drinking water have an increased risk of gastrointestinal tumours.

A recent study by the Environmental Working Group (EWG), a non-profit research organisation, demonstrated chromium VI in the drinking water of 31 out of 35 US cities tested, with the highest levels in samples from Norman, Oklahoma, Honolulu, Hawaii, and Riverside, California.

As a result, the US EPA has advised US water utilities to test more carefully for its presence in water supplies.

WTW products from ITT Analytics provide simple, convenient and cost-effective tests for measurement of chromium VI in the field or the lab.

The WTW Photoflex Photometer offers a simple portable lab while the Photolab 6100 VIS research-grade spectrophotometer offers flexibility while minimising bench space.

Chemistry test kits, available in a variety of sensitivity levels, all meet the current EPA chromium VI detection limits.

The OI Analytical DA 3500 discrete analyser from ITT Analytics measures multiple analytes, such as chromium VI, phosphate, and nitrite, concurrently, allowing samples to be analysed immediately upon receipt in the laboratory.

This colorimetric chemistry analyser enables drinking water facilities to analyse samples for chromium VI within 24 hours, as required by the US EPA.

ITT Analytics will showcase its range of measurement options for the detection of chromium in drinking water in booth 3761 at Pittcon 2011, running from 14-17 March in Atlanta, Georgia.
