Lead-in-Water Information

Protection of public health is the City of Hillsboro Water Department’s number one priority. 

Water is tested regularly to ensure every drop in the Hillsboro water system is safe to drink. This includes lead sampling, the only water testing done by the Hillsboro Water Department using samples pulled from the very end of the distribution system – our customer’s taps.

Free Lead-in-Water Testing Program

Lead is a major health threat to children and pregnant women. If your home was built between 1970 and 1985, lead solder may have been used to join the pipes. Testing at the tap is the only way to know if the solder is leaching lead into your drinking water. 

On July 1, 2016, the Water Department began providing free lead-in-water testing kits to residents, childcare facilities (daycares), and nonprofit organizations who are current customers and located in the Hillsboro Water Department's service area. While the free lead-in-water testing kits are not being currently offered to businesses, the Water Department is available to provide information on accredited laboratories to any commercial customers wanting to test their facilities.

Qualifying customers served by the Water Department can pick up a test kit, take water samples, and drop them off at the Water Department Monday through Friday, 8 am to 4:30 pm, at the Hillsboro Civic Center, 150 E Main Street, Third Floor, excluding holidays.

Test kits include:

Water samples taken by customers will be analyzed by an Oregon Health Authority accredited laboratory. Results from the laboratory will be provided to the Water Department who will email the results to the respective customer.

If results show the customer's water sample exceeds the recommended action level set by the Environmental Protection Agency (EPA) of 15 parts per billion, Water Department staff will work with the customer on a re-sample and provide information on reducing lead exposure through drinking water.

With the exception of re-samples for customers exceeding the action level, customers can only request free lead testing through the Water Department once every two years.


Statement of Liability

The Water Department provides free lead testing to qualifying customers as a community service. The Water Department has no responsibility or authority to enforce any action on the customer for reduction of lead exposure. The responsibility for identifying and implementing any actions needed to address lead levels detected at or above the action level at the customer's testing location rests solely with the customer.
