This 27,000 square foot laboratory receives almost 40,000 samples each year and its staff performs more than 200,000 chemical and biological analyses each year. Some of the tests are required by agencies that monitor water and wastewater treatment plants. The number of tests has been steadily climbing and is expected to exceed 300,000 by 2012. The additional tests are the result of new and more stringent regulations and an increased number of requests for assistance from outside agencies.

The International Water Quality Laboratory had a construction value of $7.6 million.

Bath designed mechanical systems including a 100% redundant air supply and exhaust system.  All duct and duct components are stainless steel.
