The Project includes the following work:
• Cleaning and video surveying two existing municipal wells on the Coyote Valley Reservation, known as Well 1 and Well 3.
• Installing a sounding tube in each of the two municipal wells.

• Installing a sonic water level sensor within each sounding tube.
• Installing a combined in-line temperature and conductivity sensor in both municipal wells.
• Integrating the sonic water level and temperature/conductivity sensors into the exiting controller system, including the installation of one transducer to convert the analog 4-20ma signal to wireless (to cover distance from Well 3) and then back to analog to be recorded by the existing Hach sc1000 datalogger.
• Installation of two new 150-foot-deep groundwater monitoring wells with 6” minimum casing, well pack, and sanitary seal, designed to improve the Tribe’s capacity to assess aquifer dynamics and protect groundwater resources.
• Abandonment of a shallow well.
