Imminent Threat Violation

A condition at a PWS that may adversely affect the quality of drinking water and presents an immediate threat to public health.

  • (TCR01) Total Coliform Rule – Overview (1424)
  • (TCR02) Total Coliform Rule – Monitoring And Reporting Requirements (1425)

Incomplete Denitrification

A condition in which environmental conditions are not optimal to provide for the conversion of nitrate to nitrogen gas (some of the nitrate remains as nitrate and some undergoes partial conversion yielding concentrations of nitrite). Typically, incomplete denitrification results in high levels of nitrate in the wastewater effluent.

  • (BNR01) Nitrification and Denitrification – An Introduction to Nitrogen Removal (1485)

Incomplete Nitrification

A condition in which not all ammonia is converted to nitrate (some of the ammonia remains as ammonia and some of the ammonia undergoes partial conversion yielding concentrations of nitrite). Typically, incomplete nitrification results in high levels of ammonia in the wastewater effluent.

  • (BNR01) Nitrification and Denitrification – An Introduction to Nitrogen Removal (1485)
  • (BNR02) Nitrification Factors – Suspended Growth Treatment Systems (1821)

Incorporation

Mixing of materials found on or spread upon the soil surface into the soil volume via the mechanical manipulation of the soil.

  • (BIO02) Biosolids Agronomic Loading Rates Part 2 – Manure (1484)

Influent

Wastewater or other liquid - raw (untreated) or partially treated - flowing INTO a reservoir, basin, treatment process, or treatment plant

  • (BNR01) Nitrification and Denitrification – An Introduction to Nitrogen Removal (1485)
  • (BNR02) Nitrification Factors – Suspended Growth Treatment Systems (1821)

Inorganic Material

Material such as sand, salt, iron, calcium and other mineral materials that are only slightly affected by the action of organisms in wastewater treatment. Inorganic matter is comprised of chemical substances of mineral origin; whereas organic matter is comprised of chemical substances that are usually of animal or plant origin.

Inorganic Waste

Waste material such as sand, salt, iron, calcium and other mineral materials that are only slightly affected by the action of organisms in wastewater treatment. Inorganic wastes are chemical substances of mineral origin; whereas organic wastes are chemical substances usually of animal or plant origin.
