Wastewater Consultation: 

Every county in Washington has different rules regarding how to discharge grow water. Pesticides, herbicides, nitrates and nitrites cannot be discharged into septic systems, and in some counties, city sewer systems.

We can help you mitigate your wastewater issues. We implement the same standards at our labs to safely handle our contaminated wastewater. We can help you achieve and maintain compliance and save fish and groundwater at the same time.
