Millions of gallons of wastewater are produced every day. Careful handling of domestic and industrial wastewater is essential for protecting our drinking water, wildlife, and other vital resources.

Domestic wastewater
News stories about environmental problems usually focus on recognizable targets like smoking industrial facilities, leaking toxic waste dumps, and messy oil spills. As a result, people often forget about water contamination caused by smaller sources, especially pollution at the household level. The EPA recommends a few ideas to reduce domestic wastewater pollution.
• Limit paved surfaces to reduce runoff and allow water to percolate into the ground.
• Properly manage septic systems to eliminate malfunctions and overflows that release bacteria into the watershed. Inspect and empty septic tanks every 3-5 years.
• Protect against soil compaction around septic systems and leach fields.
• Use water-efficient showerheads, faucets, and toilets to limit wastewater production.

Storm water
In undeveloped areas, rainfall is naturally filtered and absorbed by its environment as it seeps into underlying soil. Conversely, runoff in urban settings collects harmful pollutants as it travels across parking lots, under equipment, through waste, and directly into storm drains. Local lakes and rivers receive this highly contaminated runoff.

Industrial Wastewater
Improper handling of industrial wastewater contributes to water quality problems in every part of the country. Industrial discharges vary widely in the amount and types of pollutants they contain. Agriculture is one of the biggest “industries” in the country, contributing pesticides, herbicides and nutrients as pollutants. Mills, mines, and power plants have distinctly different wastes from smaller facilities like car washes and laundromats. Large volumes of wastewater are often discharged into small streams that have limited ability to assimilate the wastes. This diversity makes blanket regulation difficult.

Neilson Research Corporation performs wastewater analyses for city, county and state government entities as well as industrial and mining facilities regulated under the Clean Water Act (CWA). The CWA regulates the discharge of wastewater into any stream or river, and is enforced under regulations outlined in National Pollution Discharge Elimination System (NPDEzS) permits. The Environmental Protection Agency (EPA) specifies methods for testing wastewater under the CWA. NRC uses only the most recently approved method allowed for analyses of NPDES samples.
