Industry History
The history of water testing dates back to ancient times when people used to observe the color, taste, and smell of water to determine its quality. In the 19th century, the first water quality standards were established in Europe and the United States. In the early 20th century, the first water treatment plants were built in the US, and water testing became more sophisticated with the development of chemical and microbiological analysis methods. In the 1970s, the Clean Water Act was passed in the US, which required regular water testing to ensure compliance with environmental regulations. In recent years, the water testing industry has seen significant growth due to increased public awareness of water quality issues, technological advancements in testing methods, and the growing demand for safe drinking water.
In the United States, the Safe Drinking Water Act was passed in 1974, which established national drinking water standards and required regular testing of public water systems. In the 1980s and 1990s, the focus of water testing shifted towards detecting contaminants such as lead, arsenic, and pesticides. In the early 2000s, the Environmental Protection Agency (EPA) introduced the Unregulated Contaminant Monitoring Rule, which required testing for a list of contaminants that were not yet regulated. In recent years, the water testing industry has faced new challenges such as emerging contaminants, climate change, and aging infrastructure. Despite these challenges, the industry continues to grow as the demand for safe and clean water remains high.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification.
