“…Collecting a few grab samples (e.g., second draw) is even more prone to missing semirandom release of particulate lead. Proportional samplers can be used to collect fractions of total daily flow (van den Hoven and Slaats, 2006 ); however, our experiences demonstrate that these conventional designs may systematically “miss” larger lead particulates because the momentum of particles carries them past small side stream samplers and causes the lead to be “missed.” Conversely, other designs may concentrate lead particulates in water samples.…”

“…We collected a water sample from the kitchen tap and also collected a second sample when there was a point-of-use filter (filter attached to the tap). We used the following procedure to standardize tap water sampling ( van den Hoven and Slaats 2006 ): a ) open the tap for 5 min, b ) close and leave untouched for 30 min, and c ) collect first draw. We added 0.15 mL nitric acid (50%) to the 50-mL water sample and stored samples at 4°C.…”

“…A convenience sample of 138 participants’ houses distributed in 37 villages was selected for drinking water sampling. In houses with water supply ( n = 92), tap water samples of 10 mL were collected into polypropylene tubes (PerformR Centrifuge tubes, Labcon, Petaluma, CA) using the following standardized procedure (adapted from van der Hoven and Slaats): 24 open the tap for three minutes, reduce flow, and collect sample. In houses with no water supply ( n = 46), women collected drinking water from wells, community taps, rivers, or bottled water and stored it in large plastic containers.…”
