When you have your water tested for other types of contaminants, the EPA maximum contaminant levels and guidelines should be used to determine if your water is safe to drink.
Please see the DNR's How to Sample Your Well Water guidance document for sampling information.
The Water Systems Council wellcare® water testing information page offers additional testing guidance.
The State Hygienic Laboratory at the University of Iowa is also a great resource and offers a number of documents for private wells.
