Camp Fire Response
In November 2018, residents of Butte County, California experienced the most destructive and deadliest wildfire in California’s history. More than 150,000 acres were burned, and this wildfire is called the “Camp Fire.” Extensive drinking water system damage and chemical contamination were uncovered in the burn area for multiple systems. The fire rendered large and small water systems and private wells broken and chemically tainted. Water system components were physically and chemically damaged above and below ground. Water loss caused depressurization and some materials likely reentered the piping networks. The large drinking water systems affected are called the Paradise Irrigation District (PID), and Del Oro Water Company systems named Paradise Pines, Lime Saddle Marina, and Magalia. A variety of other public water systems were also impacted as well.
As residents rebuild, drinking water contamination is proving to be a very significant problem. In January 2019, a team of engineering and science professors from Purdue University and Manhattan College were called in to provide technical assistance. From February 11-13, they inspected damaged areas and visited with water utilities, local, state, and federal officials. While there, the team proposed a prioritization of response actions to expedite damage assessment and community recovery to the PID, town, county, state, and federal officials.
One of their major findings was that people living in the burn area lacked much needed building water safety guidance. While many efforts were underway to understand and resolve water distribution system issues, people did not have guidance on how to determine if their plumbing was safe or requires replacement. People also did not have guidance on what they should consider when selecting in-building water treatment devices. This gap was identified to local, state, and federal agencies and a recommendation was made to immediately provide drinking water safety guidance to these individuals. A copy of the draft findings presented to utilities, town, county, state, and federal agencies can be found here (Agenda pages 20-25).
Thank you for visiting. Please contact the team at firstname.lastname@example.org if you have any questions, insights, or information you think they should know. We have also posted frequently asked questions (FAQ) received from persons affected by the Camp Fire. Presentations we have delivered about the Camp Fire response and recovery are posted here.

Public Community Meeting in Paradise, California - March 26, 2019
Video of the meeting is available at http://facebook.com/CaliforniaOES/videos/277200146550998/
Much of our project activities were developed through personal interactions with Butte County residents, the health department, local utilities, government, state government and federal agencies. For perspective you could consider watching this March 26, 2019 public meeting about drinking water hosted by the Paradise Irrigation District (PID). Representatives from the PID, Town of Paradise, and our team answered questions with the public.
The meeting was organized by the CalOES (California Governor’s Office of Emergency Services). Left to Right: PID Manager Kevin Phillips, PID Water Distribution System Supervisor Jim Ladrini, Purdue University Professor Dr. Andrew Whelton, Town of Paradise Manager Lauren Gill, PID Director of the Advisory Board Marc Sulik. The first 30 minutes was an update about system damage and actions to date. The next two-and-a-half hours was a Question and Answer Session.
Camp Fire Support Team - Professional Biographies
|The Purdue University science and engineering team is led by Andrew Whelton, Ph.D. an environmental engineering faculty member, who is nationally recognized for water infrastructure contamination and recovery. Dr. Whelton has 16 years’ of experience, and is an associate professor of civil, environmental, and ecological engineering at Purdue University. In 2014, he was called in by West Virginia Governor Earl Ray Tomblin after the 2014 Charleston chemical spill. The incident contaminated the capitol city’s sole 50 MGD treatment plant, 2200 miles of water mains, 107 storage tanks, and 120 booster stations across 124 pressure zones. About 15% of the state’s population was issued a do not use order. Through two research teams he assisted the state and community recover from the incident. His research teams have identified best practices for planning for and recovering from natural and made-made disasters that affect drinking water systems. He has extensive experience understanding material aging and chemical fate in water distribution systems and building plumbing, with an emphasis in plastic materials. He has organized and presented town hall public meetings, conducted sampling at private residences, government buildings, and provided Governor’s staff feedback on evidence-based public messaging, and engaged in press conferences. At present, he’s leading a nationally funded drinking water plumbing safety initiative with multiple universities and industrial collaborators. He previously worked for the U.S. Army, National Institute for Standards and Technology (NIST), and private firms. He earned a B.S. in Civil Engineering, M.S. in Environmental Engineering, and Ph.D. in Civil Engineering from Virginia Tech.|
|Amisha Shah, Ph.D. is a chemical and environmental engineer with 11 years of experience in environmental chemistry, analytical instrumentation and analysis, physiochemical process design and optimization. Her work primarily focuses on evaluating the reaction kinetics and pathways of various organic contaminants during water disinfection. Due to this work, she has extensive analytical expertise in measuring a wide-array of volatile and non-volatile organic compounds via HPLC, LC/MS/MS, GC/MS/MS, GC-ECD, IC, and IC/MS/MS. These compounds have included trihalomethanes (THMs), haloacetic acids (HAA), polycyclic aromatic hydrocarbons (PAHs), aromatic nitrogen compounds, low molecular weight organic sulfur compounds (COS, CS2, and DMS), sulfur-based amino acids, and perfluoroalkyl substances (PFASs). In her recent efforts, she has placed an important focus towards evaluating how chemical interactions in aqueous systems can be strongly influenced by their surrounding water matrix. Other research efforts have found that different water quality parameters can significantly influence disinfection by-product formation from cross-linked polyethylene (PEX) pipes that are routinely used in premise plumbing. Dr. Shah earned a B.S. in Chemical Engineering from Washington University at St. Louis and Ph.D. in Environmental Engineering from Georgia Technical Institute of Technology. She has previously worked for EAWAG, the Swiss Federal Institute of Aquatic Science and Technology in Switzerland and Yale University in New Haven, Connecticut.|
