The Water Supply Operations (WSO) Section is responsible for certifying public water supply (drinking
water) treatment and distribution operators, and wastewater and lagoon
operators. The purpose of the OpCert program is to ensure that water and
wastewater operators have sufficient knowledge and experience to properly
operate the system, and in turn protect human health and safety, the
environment, and the infrastructure investment.
Laboratories reporting environmental data to the DNR must be certified. The objective of the certification program is to ensure that the results of testing performed are accurate and legally defensible. The WSO Section certifies laboratories within the State and across the United States for the following environmental programs:
Iowa requires the certification of all professionals who construct water wells and geothermal heat exchange loop boreholes, and those who perform well pump and water system related services. Certified well contractors have demonstrated that they have the knowledge and experience necessary to understand how their activities affect the groundwater and influence the services they provide to their customers. The WSO Section is responsible for administering the certification program.

The current certifications include the following:

Producers who handle, transport, and land apply manure from a confinement feeding operation with an animal unit capacity of more than 500 animal units must be certified or use a commercial manure applicator. Producers with small animal feeding operations (500 or less animal unit capacity) or open feedlots may land apply manure without being certified. All manure applicators in Iowa, regardless of certification requirements, must follow state laws when land applying manure. The DNR is responsible for the certification program and offers certification for two types of manure applicators:
