Summary of New Jersey's Water Reuse Guideline or Regulation for Agriculture

This page is part of the EPA’s REUSExplorer tool, which summarizes the different state level regulations or guidelines for water reuse for a variety of sources and end-uses.
The source water for this summary is Treated Municipal Wastewater.

In New Jersey, water reuse for water reuse for agricultureThe use of recycled water to land to assist in the production of both commercially and non-commercially processed food crops consumed by humans or livestock and non-food crops. Includes pasture for milking and non-milking animals, fodder, fiber, and seed crops, vineyards, orchards, ornamental nursery stock, Christmas trees, and silviculture. Excludes consumption by livestock, onsite non-potable reuse, and landscaping. includes irrigation of non-edible crops, including spray irrigation of sod farms and pasturelands, or similar areas where public access to the application area is restricted and edible crops if those crops will be peeled, skinned, cooked or thermally processed before consumption; irrigation using an indirect application method that precludes direct contact with the reclaimed water. The source of water treated municipal wastewater Treated wastewater effluent discharged from a centralized wastewater treatment plant of any size. Other terms referring to this source of water include domestic wastewater, treated wastewater effluent, reclaimed water, and treated sewage. is specified by the state as municipal wastewater. This write-up uses state terms when discussing sources or uses of water that may differ from the Regulations and End-Use Specifications Explorer's (REUSExplorer's) terms.

Technical basis

New Jersey approves the beneficial use of reclaimed water for agricultural irrigation of edible and non-edible crops. New Jersey refers to this approach as “reclaimed water for beneficial reuse” (RWBR). RWBR programs must be authorized by the New Jersey Department of Environmental Protection (NJDEP) under a New Jersey Pollutant Discharge Elimination System (NJPDES) permit (NJDEP, 2005). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any relevant rule requirements under the Food Safety Modernization Act (FSMA) (124 Stat. 3885). Restrictions on public access are specified for Type II RWBR Restricted Access and Non-Edible Crop Systems but not for other reuse categories with agriculture. Treatment requirements and performance standards are applied for the removal of microbial contaminants, chemicals and other relevant indicators related to agriculture and are summarized in the table. The technical basis for developing the specifications and/or removals of microbial contaminants, chemicals and other relevant indicators is not explicitly specified.

Water reuse for agriculture approved for use in New Jersey

NJDEP (2005) defines the following approved agricultural use of reclaimed water for beneficial reuse (RWBR):

  • Irrigation of non-edible crops including spray irrigation of sod farms and pasturelands, or similar areas where public access to the application area is restricted (Type II RWBR Restricted Access and Non-Edible Crop Systems)
  • Spray irrigation of edible crops if those crops will be peeled, skinned, cooked or thermally processed before consumption (Type III RWBR – Agricultural Edible Crop Systems)
  • Irrigation using an indirect application method that precludes direct contact with the reclaimed water, such as ridge and furrow irrigation (Type III RWBR Agricultural Edible Crop Systems)

Water reuse treatment category for agriculture

In New Jersey, reclaimed water for beneficial reuse is defined as “taking what was once considered a waste product, giving it a specialized level of treatment and using the resulting high-quality reclaimed water for beneficial uses.” The various classes of reclaimed water treatment are defined by their respective treatment requirements and applicable performance standards. The respective treatment requirements are briefly summarized regarding water reuse for agriculture:

  • For Type II RWBR Restricted Access and Non-Edible Crop Systems, disinfection is required. For UV disinfection, a design UV dose of 75 mJ/cm2 under the maximum daily flow must be used. Specific treatment requirements for disinfection using chlorine, ozone or other methods are not provided. 
  • For Type III RWBR Agricultural Edible Crop Systems, disinfection is required using chlorine, UV or an approved alternative method like ozone. For chlorine disinfection, a total chlorine residual of 1.0 mg/L must be maintained for a minimum contact time of 15 minutes at peak hourly flow. For UV disinfection, a design UV dose of 100 mJ/cm2 under the maximum daily flow must be used.

Additional context and definitions

For Type II RWBR Restricted Access and Non-Edible Crop Systems, the distribution of RWBR should not produce surface runoff or ponding for any significant amount of time and land application sites should not be frozen or saturated when applying RWBR. For a period of 15 days from the last application of reclaimed water, land application areas should not be used for the grazing of cattle whose milk is intended for human consumption (NJDEP, 2005). There are no restrictions on the grazing of other cattle (NJDEP, 2005). 

For public access RWBR, including Type III RWBR Agricultural Edible Crop Systems, New Jersey requires advisory signs to posted that notify the public of the nature of the reuse in the project area where reuse is practiced (NJDEP, 2005). The use of purple as the color of the signs is encouraged but not required. No cross connections between RWBR delivery pipes and potable water systems are allowed and RWBR delivery pipes cannot be connected into “any stormwater conveyance or pipe that is not the final delivery point prior to final use” (NJDEP, 2005).

Disclaimers

Disclaimers

The Regulations and End-Use Specifications Explorer (REUSExplorer) is intended to be a synthesis of state laws and policies governing water reuse across the US for informational purposes only. These summaries are not legally binding and do not replace or modify any state or federal laws. In the case of any conflict between these summaries and a state or federal law, the state or federal law governs. Numeric and other types of water reuse standards and specification regulations are included in these summaries, but not necessarily all relevant state laws. It is possible a state law authorizes types of water reuse, while no reuse standards and/or specification regulations have been adopted.

Inclusion/Exclusion Criteria

References were included if they could be categorized as either an act, standard, regulation, criteria, guideline, guidance document, technical manual, or appendix issued by a government, standards organization (e.g., ISO, NSF/ANSI), professional association (e.g., AWWA, IWA), research sponsor (e.g., WERF, WRF), or expert committee (e.g., National Academies) and considered to be active or adopted. References were excluded if they indicated that a state approved reuse projects on a case-by-case basis only; contained no water quality specifications or requirements; and/or focused on land disposal of both water and biosolids rather than a specific reuse application.
