Eastern Analytical, Inc. (EAI) is a NELAC-accredited laboratory with over 40 years of experience analyzing environmental samples for contaminants. As a 100% employee-owned laboratory, we understand what it takes to provide the best in customer service and analytical testing—especially when it comes to examining the health of water bodies.
Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground. This, in turn, allows water to rapidly enter sewer systems, storm drains, and drainage ditches.
Stormwater can pick up debris, chemicals, dirt, and other pollutants that threaten to affect the quality of water bodies we use for swimming, fishing, and drinking water. These typical contaminants may include:
- Solids & sediments
- Oil & greases
- Chemicals & acids
Contaminated stormwater can easily flow into storm sewer systems or directly to a lake, stream, river, wetland, or coastal water body—and anything that enters a storm sewer system is discharged, untreated, into these crucial water bodies.
