Should state governments provide free water safety testing for all private-well households in your area?
The Delaware Department of Natural Resources and Environmental Control and the Department of Health and Social Services have established a free private-well sampling program. This state effort follows concerns regarding drinking water safety and provides financial assistance for filtration systems.
Why it matters
Private wells remain exempt from public water regulations, leaving owners solely responsible for monitoring their water quality. This program bridges a critical gap for residents by funding essential safety testing and equipment for lower-income households.
The program provides 100% of installation and one-year maintenance costs for low-income households and 50% for moderate-income owners. This follows a 18-month toxicology study that included nine distinct sampling events across various communities.
The players
Department of Natural Resources and Environmental Control
A Delaware state agency responsible for the management and protection of natural resources and environmental regulatory compliance.
Department of Health and Social Services
The Delaware state agency that oversees public health programs and manages state health service delivery.
The details
Residents must file a state private well water sampling request and consent form to participate. Agencies then use the ALICE Budget and Income Status Tool to determine financial assistance tiers for system upgrades. If test results exceed the EPA maximum contaminant levels, including the 4 parts per trillion limit for PFOA and PFOS, the Department of Public Health notifies households within 48 hours.
Timeline
The EPA set maximum contaminant levels for PFOA and PFOS in April 2024.
The first sampling event occurred on Jan. 29, 2025.
The final sampling event took place on July 20, 2026.
Market Landscape
The program follows the EPA’s April 2024 establishment of strict maximum contaminant levels for chemicals like PFOA and PFOS. These federal standards set a clear baseline for state-level water testing, marking a formal increase in regulatory rigor for groundwater safety.
Well owners should evaluate their water systems against the new EPA contaminant thresholds to determine if testing is required. Owners should use the ALICE Budget and Income Status Tool to verify eligibility for state-funded cost coverage before purchasing filtration hardware.
The takeaway
Private-well owners are legally responsible for their own water monitoring and lack the protections afforded to users of public systems. Review the state-provided testing criteria to ensure your water source meets current health guidelines.
