An overgrowth of cyanobacteria. Examples of physical contaminants are sediment or organic material suspended in the water of lakes, rivers and streams from soil erosion. Heavy metals can enter a water supply by industrial and consumer waste, or even from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers, and groundwater. However, the primary sources are human and animal waste, and agricultural activities, including the use of fertilizers, and so on. Rain or irrigation water can carry nitrate down through the soil into groundwater. Leaking water pipes can allow potentially harmful contaminants into our drinking water, new research has shown.

Contamination of drinking water sources by sewage can occur from raw sewage overflow, septic tanks, leaking sewer lines, land application of sludge and partially treated waste water. How did these chemicals manage to get into so many drinking water systems? Aluminum: Because it is an abundant metal in the earth’s crust, aluminum may leach into groundwater. Natural bacteria in soil can convert nitrogen into nitrate. We test extensively to make sure that our water meets or exceeds all drinking water standards. What Do My Customers Want To Know About Chronic Contaminants? Asbestos is a naturally occurring mineral. Unregulated contaminants are those that do not yet have a drinking water standard set by EPA.
