EPA ADVANCED SEPTIC SYSTEM NITROGEN SENSOR CHALLENGE

Back to Project List

Project Highlights

Sensors will measure nitrate, nitrite, ammonia, or Total Nitrogen.
Sensor data compared to certified laboratory results.
Maximum sensor cost: $1,500.

The EPA Advanced Septic System Nitrogen Sensor Challenge seeks to spur market development of an accurate and precise low-cost sensor to measure nitrogen compounds in wastewaters associated with onsite septic systems.
