Jacelyn Renwick is a dedicated volunteer who gives her all to various causes. She helps out at non-profits, supports her co-workers as a union president, and volunteers for her local CWEA chapter. When asked about her motivation for volunteering, she said she firmly believes that if you care about something, you should dedicate your time and energy to helping it grow and succeed.
She currently works as the laboratory supervisor for the City of Manteca’s public works department.
“Jacelyn is truly an emerging leader within the wastewater industry,” said her co-worker Lissett Mayorga, the City of Manteca’s water resources coordinator. “She has great communication skills and is a natural team builder. Jacelyn doesn’t shy away from difficult conversations. She believes in each employee and provides her technicians with opportunities.”
After graduating from Cal State Stanislaus with a biology degree in 2006, Renwick began her career with the City of Manteca. Throughout the years, she has steadily advanced from Lab Tech 1 to Lab Tech 2. In 2022, she became the Laboratory Supervisor for the City’s wastewater/water facility. The city runs a tertiary treatment facility using ultraviolet light, with processed water released into the San Joaquin River.
“Taking on the position of supervisor has been a rewarding experience,” Renwick said. “The most important part of the job is making sure that the staff is doing the best they can do, so the lab can be at its best.”
As the supervisor, Renwick oversees a team of four laboratory technicians, manages budget and report preparation, procures necessary materials, hires and trains personnel, provides technical management, and leads during audits. With the support of upper management, she also ensures accurate interpretation of The NELAC Institute (TNI) standards. Renwick is respected by her colleagues and team for her expertise and leadership skills.
Renwick’s career path took a surprising turn when she landed a temporary job in the environmental lab with the City of Manteca right after she graduated from college. This experience opened her eyes to a whole new world of possibilities. After taking on a full-time position in Manteca, she quickly became involved with CWEA’s Northern San Joaquin Section. With dedication and hard work, Renwick has held every Board position with the local section and currently serves as treasurer. Her journey serves as a reminder that sometimes the unexpected can lead to the most fulfilling opportunities.
According to Renwick, being the union president of her city is among the most significant responsibilities she has ever accepted.
“It is important to me that staff and colleagues are supported in labor rights and producing the best quality data with up-to-date methods,” she said.
She is currently working on the new Environmental Laboratory Accredidation Program (ELAP) requirements and making sure that the lab is in compliance. ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State’s drinking water and wastewater programs.
