Water Quality Testing. If the village installs a wastewater treatment system, then the county EEB will require routine testing of the raw wastewater entering the system (influent) and the treated water leaving the plant (effluent). The frequency of testing will be prescribed by the county EEB, but is commonly monthly during the startup phase, which may be a 3 to 6 month period, and after the treatment system is shown to be working properly the testing may be conducted quarterly. The basic tests that should be conducted on a regular interval include:
- Biochemical oxygen demand (BOD)
- Total suspended solids (TSS)
- Ammonia-nitrogen
- Organic nitrogen (Total Kjeldalh Nitrogen)
- Total phosphorus
- pH
Flow Measurements. The wastewater treatment system should include a flow measuring device, such as a weir plate or a flow meter, so that the village operator can record daily flows.
Groundwater Monitoring. A groundwater monitoring network will be required to monitor shallow groundwater conditions down gradient from the land disposal system. This will usually involve installing at least three monitoring wells: one well installed upgradient from the land disposal system and two wells installed down gradient of the land disposal area. A minimum of three wells is needed to determine the horizontal direction of flow of shallow groundwater. The wells should be installed a sufficient distant away from the land disposal system so that the wells are monitoring groundwater and not effluent from the drainfields. The groundwater monitoring wells should be monitored on a quarterly basis for the following parameters:
- Groundwater levels
- pH
- General minerals, including:
- Sodium
- Chloride
- Potassium
- Magnesium
- Sulfate
- Bicarbonate
- Fluoride
- Nitrate (as N)
