The bill also requires DNR to test for PFAS contamination in soil and
groundwater in areas where biosolids have been land applied for at least 10 years
and where vulnerable aquifers are present. The bill provides $2,000,000 in GPR
funding for this purpose.
Statewide PFAS biomonitoring studies
The bill requires DHS to conduct biomonitoring studies across the state to
assess PFAS exposure levels and better understand the factors that affect PFAS
levels in residents of different communities. As part of these studies, DHS may
survey volunteer participants, test blood samples for PFAS, and analyze the results.
The bill authorizes 5.0 additional FTE positions in DHS to conduct these studies and
provides $630,000 in annual GPR funding for this purpose.
Report on regulating PFAS as a class
The bill also requires DNR and DHS to submit a joint report to the legislature,
no later than June 30, 2026, on the feasibility and advisability of regulating PFAS
as one or more classes of substances.
DATCP testing for PFAS
Under current law, the Department of Agriculture, Trade and Consumer
Protection conducts several statewide monitoring programs, sampling programs,
and surveys related to testing groundwater quality for agricultural purposes. The
bill requires that, when collecting and testing samples under one of these statewide
programs, DATCP must also, at its discretion and where appropriate, test samples
for the presence of PFAS.
Funding for statewide PFAS sampling and testing
The bill also increases SEG funding for DNR by $1,480,000 in fiscal year
2023-24 and $730,000 in fiscal year 2024-25 for statewide PFAS sampling and
testing activities.
Funding for PFAS substance emergency measures
The bill also increases SEG funding for DNR by $900,000 annually for PFAS
emergency measures.
Funding for fire fighting foam collection
The bill also increases SEG funding for DNR by $1,000,000 for the purpose of
collecting and disposing of PFAS-containing fire fighting foam.

Funding for PFAS outreach and awareness
The bill also increases GPR funding for DHS by $500,000 annually for PFAS
outreach and awareness activities.
DNR PFAS positions
The bill authorizes 12.0 additional GPR positions relating to PFAS in DNR and
provides funding for those positions.
DHS PFAS positions
The bill authorizes 4.0 additional GPR positions in DHS for the purpose of
recommending groundwater enforcement standards for PFAS and provides funding
for those positions.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
