The gradient descends from east to west. 4.2 Description/discussion of any existing and/or potential groundwater contamination issues in the general location of the site: The concerns for groundwater contamination in this area are deemed moderate due to the depths involved. Insecticides, pesticides, and fertilizers typically do not significantly impact groundwater at these depths. The subject property itself and the adjacent parcels have been used for industrial facilities. There are several waste ponds and detention ponds to the northeast of the site that should be monitored to avoid contaminants from accumulating. 4.3 Description of location (address/APN), type and construction of well and location (well head/kitchen tap) where water sample(s) were obtained: Water samples were taken from a spigot at the well located on the subject property at 12405 Brandt Road on April 12, 2022 by Bradley Handel of Dillon & Murphy. 4.4. Description of constituents being tested for in the water sample: The water samples are being tested for nitrates and DBCP. 4.5 Description of how sample was obtained, handled, stored, and transported to the lab: The water samples were obtained from a spigot at the well located on the subject property at 12405 Brandt Road. The samples were taken by Bradley Handel of Dillon & Murphy, and driven directly to Precision Enviro-Tech. The samples were taken and handled in accordance with Precision Enviro-Tech requirements. The results from the test can be found in the Appendix. 4.6 Complete Chain of Custody document, including printed and signed name of third party sampler, condition of sample and date and time the sample was submitted to the lab.
