New Daycare Facilities

Centers must certify safe drinking water is being provided. Applicants are required to certify that their center provides safe drinking water before the DCF Office of Licensing approves any application to operate a childcare center.

If a Childcare Facility is connected to a community well water system, the Facility is required to provide documentation, including the name of the community well water system, and either a copy of a recent water bill indicating service to the applicant’s address, or a letter from the public community well water system certifying the service to the address in question.

Finding Your Public Water System

To locate the name of the public water system serving you, visit here. The drop down menus allow you to search by, county, municipality, and/or Public Works Identification number (PWID).

If the Childcare Facility is not served by a community well water system, the center must prove they provide potable water which meets the Maximum Contaminant Levels (MCLs), including radiological contaminants. We  recommend you contact the New Jersey Department of Environmental Protection’s Bureau of Safe Drinking Water at (609) 292-5550 before sampling.

Sampling Procedures and Parameters

  1. Sampling must be performed within three years prior of the application submission, except nitrates and coliform. Sampling for these must be done within 90 days of application.
  2. All analysis must be conducted by a laboratory certified for appropriate drinking water parameters by the New Jersey Department of Environmental Protection’s Office of Quality Assurance.
  3. Analytical methods and QA/QC protocols should be those used for compliance by community and non-transient non-community water systems as specified in the Federal and State Safe Drinking Water Act Regulations.
  4. Sampling for all contaminants shall be of raw water, collected prior to any treatment. If treatment exists on the well to address a particular contaminant, the water shall also be tested after treatment for that contaminant.
  5. Analysis must be for the following parameters:
    • Nitrate
    • Arsenic
    • Coliform: If total coliform bacteria are detected, a test must also be conducted for fecal coliform or E. coli.
    • Volatile organic compounds including all for which federal or New Jersey Maximum Contaminant Levels exist.
    • Inorganic compounds: antimony, arsenic, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, selenium, thallium.
    • Radiological contaminants: gross alpha particle activity, radium 226, radium 228, and uranium. It may not be necessary to analyze the sample for radium 226 and uranium if the concentrations of gross alpha particle activity and radium 228 are sufficiently low. In addition, it may be acceptable to only conduct one round of sampling for radiological contaminants instead of with each renewal.
    • Synthetic organic compounds: dibromochloropropane (DBCP), ethylene dibromide (EDB) and 1,2,3-Trichloropropane. It may be sufficient to conduct one round of sampling for these synthetic organic compounds instead of with each renewal. Analysis for these compounds must be conducted using USEPA Method 504.1.
    • Secondary contaminants: Chloride, hardness (as CaCO3), iron, manganese, sodium, sulfate, total dissolved solids, zinc, pH.
    • Lead and copper. The location and number of samples for lead and copper shall be conducted as if Child Care Facility were a non-transient non-community water system.
