What shape should soil samples be collected from small patches or play areas with bare soil?

X grid
Circle grid
Triangle grid
Square grid

The correct answer is: X grid

The recommended method for collecting soil samples from small patches or play areas with bare soil is to use an X grid shape. This approach allows for a systematic and thorough assessment of the area, ensuring that samples are taken from representative locations. The X grid pattern helps to maximize coverage of the sampling area by intersecting various points within the space, effectively capturing variations in soil lead levels that may be present. In contrast to other grid shapes, such as circles or squares, the X grid enables the sampler to focus on cross-sectional areas, which can be particularly useful in smaller, irregularly shaped locations. This method fulfills the need for adequate sampling without the risk of missing localized hotspots of contamination. By employing this strategy, assessors can obtain a more accurate representation of lead presence in the soil, contributing to better risk assessment outcomes for children playing in those areas.
