On the other hand, data from 1989-1997 showed that 50% of the industries that performed acute tests failed at least one. Industrial facilities failed 140 of 847 total acute tests performed, or 16.5% of the time. Data also shows that industrial facilities are a little more likely to fail chronic WET tests. Data from 1989-1997 showed that 23% of the municipalities that performed chronic tests failed at least one. On an individual test basis, municipalities failed 53 of 373 tests, or about 14% of the time. This same time period showed that 42% of the industries that performed chronic tests failed at least one.
