The Pines Groundwater Site is located about 4 miles west of Michigan City and about 1 mile south of Lake Michigan in Porter County, Indiana.
The U.S. Environmental Protection Agency tested residential drinking water wells in the Town of Pines In May 2002, based on high levels of the metals boron and molybdenum found in drinking water wells by the Indiana Department of Environmental Management. The metals appeared to come from coal combustion by-products, or CCBs, composed primarily of fly ash that was disposed of in a nearby landfill called Yard 520. Other areas in the town were also identified as having CCB materials. Ash, primarily bottom ash, was used as fill in residential yards as well as road surfaces and subsurfaces. CCBs are the result of burning coal to make electricity.
In 2003 and 2004, Northern Indiana Public Service Company, Brown, Inc., Ddalt Corp., and Bulk Transport, the companies determined to be responsible for the contamination, agreed to provide municipal water to about 270 homes in and near the Town of Pines. About 70 more homes received bottled water pending the results of an investigation. The results are summarized in a 2010 document called a remedial investigation report.

Results from soil samples taken by EPA and NIPSCO at nine properties in late 2014 have indicated that seven of them have higher than normal levels of arsenic. This was most likely caused by fly ash used as landscaping fill in the 1970s. NIPSCO has been in communication with EPA, as well as each of the property owners, about the results and to discuss the next steps. The properties were selected by EPA and the local community group People in Need of Environmental Safety (PINES), as part of a continuing investigation to assess the presence of coal ash.
Soil was also tested at several dozen private and public properties in spring 2014 by a contractor for the companies responsible for investigating the coal ash contamination in the town. Permission to do so was obtained from the property owners. The testing, which was overseen by EPA, involved a general radiation scan to see if high levels are present and involved workers walking around yards with monitoring equipment. The results of the general radiation scans can be found in a summary table Summary Table (PDF) (5pp, 232 K).
The PINES group currently has an EPA technical assistance plan to receive services such as technical advice and community outreach assistance valued at more than $50,000.
In July 2014, EPA received a fourth draft of the feasibility study which includes several possible groundwater cleanup options. EPA cannot approve this study until the soil/arsenic contamination is dealt with. When the study is approved, EPA will propose a groundwater cleanup plan and present it to the public for review and comment. EPA hopes a final cleanup decision can be made by late 2015 after public comments are considered.

- After a meeting USEPA held in 2004, representatives reported to Beverly Shores residents that test results from their water had low levels of boron. Shortly after the meeting, several residents in the Beverly Shores area had their water tested; some of the tests showed high boron levels. The U.S. Geological Survey did a study and survey for the groundwater in the Beverly Shores area. The results of this survey stated that the boron in the Beverly Shores water was not from the landfill, but the boron was naturally occurring.
