Surface Water

In  environmental  waters,  water  quality is degraded when pollutants in the water cause conditions to exceed the aquatic system’s ability to balance the changes.    Two  major  categories  of water pollutants include: point source pollutants  from  specific  sources  such as  industrial  pipes;  and  diffuse  land-based non-point source pollutants carried to water bodies by runoff. In order to identify, control, and remediate pollutants, water quality monitoring  can  be  conducted  in  a  variety  of ways to meet many purposes.
