Findings
SWPP staff conducted shelf surveys at 10 retail stores and identified 194 indoor-use pesticide
products with 62 AIs representing 16 chemical classes. Nearly half the products identified are
designated for use on pets. The AIs have been classified as high, intermediate, or low priority for
future wastewater monitoring efforts. There may be additional pathways for pesticides to enter
the wastewater collection system; however, the shelf survey does provide a reasonable starting
point to understand which AIs should be included in efforts to develop and validate analytical
methods for a wastewater matrix for future monitoring.
