Test results announced by the City of Evanston today confirm theories that the city's water supply has small amounts of the probable carcinogen hexavalent chromium.
The test showed a level of 0.27 parts per billion, slightly higher than the 0.18 parts per billion reported in a test of Chicago's water supply reported in December.
Test results announced by the City of Evanston today confirm theories that the city's water supply has small amounts of the probable carcinogen hexavalent chromium.
The test showed a level of 0.27 parts per billion, slightly higher than the 0.18 parts per billion reported in a test of Chicago's water supply reported in December.
Those levels are higher than what would be permitted under a proposed standard being considered by the state of California, but still far below levels set in current standards established by the federal Environmental Protection Agency.
