Likely Source of Contamination was Use
This case study involved the purchase of a rural property by a couple as a place for retirement. Renovations were being undertaken and the owners stayed in the property for only a few days at a time over a period of approximately 2 years. The property was purchased from a deceased estate. The previous owners had built the home, which was very well presented and clean. The new owners undertook a number of renovations, including painting. Once these works were complete, they spent more time at the home. When they had purchased the house, they asked the real estate agent about any former drug history and were told there was no history. Once they moved in, neighbours informed them that the previous owners were troublesome and involved with drug activities (potentially dealing), and the property was found to have been known to police. Both owners had a number of unexplained health effects since taking possession of the property, in particular the adult male. Once the property was known to be contaminated, they no longer entered the property without PPE. They organised to get the property tested and remediated. The initial testing focused on surfaces that were not renovated or painted by the owners. Further testing was then undertaken on all other surfaces in the property, including some areas where the paint was sanded back to identify levels of contamination beneath the freshly painted surface. This property had a significant number of samples collected from a range of surfaces and areas that the owners would come into direct contact.
22 of the 63 participants of this study reported health effects as indicated by levels of contamination reported in the green section of the below chart. This means that the adult who was intending to move into this contaminated property may have suffered: Behavioural Issues, Heachaches, Sleep Disruption, Immune related disorder, Respiratory Issues, Eye issues and Skin irritation.
Note that both persons who were in the property for only a few days at a time over the course of 2 years, had a number of unexplained health effects.
The study states; "In terms of health effects reported by participants exposed in contaminated properties, these were consistently reported regardless of the source of the methamphetamine contamination. The only key difference in the health effects reported was a higher prevalence of eye and respiratory issues in properties known or suspected to have been contaminated from manufacture."
