Parkland Water Hardness & Quality Report (2026)

Parkland Light & Water Company serves 29,539 residents across three cities in Pierce County, Washington, with its service area encompassing communities in the Puget Sound region near Tacoma. The utility draws from both groundwater and surface water sources, including local creeks such as Clover Creek. Treatment methods include disinfection, aeration, biological filtration, conventional filtration, and air stripping to address microbial and chemical contaminants. Chlorine serves as the primary disinfectant, ensuring microbiological safety throughout the distribution network for all served communities.

The Puget Sound lowlands watershed underlying Parkland is characterized by Quaternary glacial deposits and unconsolidated sediments left by retreating ice sheets. Groundwater is drawn from permeable glacial aquifers, while surface water contributions come from local streams including Clover Creek. The underlying geology — primarily granitic and metamorphic bedrock — combined with the region's abundant precipitation and rapid groundwater recharge, results in a naturally soft water supply with minimal dissolved mineral content throughout the service area.

Soft water in Parkland means minimal scale buildup in pipes and appliances, reduced soap scum formation, and lower maintenance demands on water heaters and dishwashers. Residents typically do not require water softening treatment. However, soft water may require pH adjustment or corrosion control to prevent copper and lead leaching from older plumbing systems. Parkland Light & Water Company has reported one contaminant above EPA health-based guidelines; residents should consult the annual Consumer Confidence Report for detailed contaminant monitoring data, lead and copper compliance results, and local advisories.
