Data, code, and output related to water lead levels

<p>The purpose of this research was to evaluate the need to repeatedly sample water from homes to identify infrequent, but high "spikes" in water lead levels due to the sporadic release of lead particulates. The Illinois and Pennsylvania data were used in establishing baseline (first round of sampling) water lead levels. The simulations were created using various assumptions of baseline prevalence and various probabilities of spike occurrence on the N+1 round of sampling, given the results on the N round.</p> <p>The findings of the research indicate that household tap water needs to be sampled at least 5–7 times to achieve a 50% probability of identifying hazardous spikes in water lead levels.</p>
