To ensure you receive the best water quality possible, both the Federal and Pennsylvania Safe Drinking Water Acts require CTA to monitor for lead and copper in your drinking water.
Because CTA has never detected lead or copper in our source water, we rely on customers to do voluntary sampling in their homes. This is the only monitoring we perform that relies completely on our customers’ participation. We are always recruiting new volunteers. Please contact us if you are interested in participating.
2022 Testing Results
From June through September 2022, Caernarvon Township Authority sampled 20 homes in our service area. We are happy to report that none of the homes that participated in this monitoring exceeded the regulated action level for lead and copper. The homes that were sampled were homes that contained lead-based solder in the household plumbing.
The data collected confirms that CTA is performing the work needed to prevent the leaching of lead and copper into our customers’ drinking water. Our results are representative of our water system as a whole. We are pleased that another monitoring period has been successfully completed. Our thanks to everyone who volunteered.
What's Next
Our most recent monitoring was concluded in the summer of 2022. The next monitoring period will begin in 2025. Testing for lead and copper in your water is incredibly important. Your test results show whether there is a harmful presence of lead or copper in your drinking water.

Proposed changes to the Lead and Copper Rule
Revisions have been submitted to the existing lead and copper rule. These revisions will require water authorities to submit service line material data for all the service lines in their service area. It also requires water authorities to work with primary schools and day care facilities to collect lead and copper water samples. These locations are important because they care for young children who are particularly susceptible to the harmful effects of lead and copper.
Here is a great link from the EPA about the proposed changes and improvements expected in the new rule.
