Artesian Water Company water system
PWSID DE0000552 · Bear,hockessin, DE. EPA's record of drinking water violations for this public water system, as retrieved October 14, 2026.
How to read this. This page copies EPA's record for one public water system from the Safe Drinking Water Information System (SDWIS), without interpretation. A violation is recorded when a water system breaks a federal or state drinking water rule. A health-based violation means a contaminant went over a federal limit or a required treatment step was not met. Most other violations are tests or reports that were missed or late. A returned to compliance date means the state recorded the violation as resolved. A past violation does not describe the water today. EPA updates this data about every three months, so the newest violations may not appear yet. Delaware's Office of Drinking Water regulates this system; if this page and the state's records differ, the state is right and we fix this page. We rank no water system and draw no conclusions.

Get this system's water quality report
Every community water system must give its customers a yearly water quality report, called a Consumer Confidence Report (CCR). It lists the contaminants found in the water and the federal limit for each. To get it, ask your water supplier (the contact is on your water bill) or check its website. EPA: how to find and read your CCR.
