<p>Additional File 2. Phase II results. Colorimetric water testing from phase I was discontinued because of a lack of consensus about results accuracy. Data show home 2010 with very high lead levels. Home 2030 data may suggest indoor sources of mold (indoor/outdoor </p><p>>30). Other parameters do not indicate exposures of concern. l ) 3 a t m o / ) t d 3 t / ) d g ) 3 s n r e 3 µ m d t d 1 2 3 ( / v m</p><p> s n r / m s - - - 3 / + 1</p><p>2 3 ) g e .</p><p> n</p><p>) ) ) s ) r - - - 2 2 2 b µ o a</p><p> e b t t t ( o ) ) ) p ) r n f f f e 2 p 2 2 / / / p ( 3 L p o t t t</p><p>/ s p ( g g g f n f f m i p t</p><p>( /</p><p>/ / l µ µ µ a s C – n g ( ( ( g g</p><p> a</p><p> w i e l</p><p> p t w µ µ µ 1 1 1 ( a a a ( ( ( o</p><p> t t t m m a t</p><p> r t</p><p> p r 2 2 2 s s s ( n o o</p><p>– d</p><p> t t t t l</p><p> d u u u o o l ( s</p><p> s s s</p><p> n r d d d d r t d a</p><p> u u u</p><p> s e s n a o r r r r g d d d w r h 1 2 d</p><p> y o o o o o</p><p> n</p><p> l l l c i e l l l t a n d r r o o o o t i i i i t l l l t v i n d e e d i f f f s s s s</p><p>D l k u t t n n n n n n n n n e d I f</p><p> n e</p><p> i o a a o o o o o o o o o n n n n n n a t o 5 5</p><p> i i i i i i i i i i i i i i i m e</p><p>. .</p><p> t t e t t t t t t t w w d d e l</p><p> e e l l 2 2 d d d d d d a a a a a a a a a ) m t s p p o o c c c c c c c c a c a a a a a o o m M M a a a a i o o o o e o o o e e o e e e o n H d t b m l m l l l l l l l l l l l l l l t t P P 200 2/01/0 2. 17 H 1/ L 36. 1. 0 8 9:30 3 150 KT 0 W 6 LR < R < BR < KT < LR < BR 17 KT 7 7 9 8 201 2/01/0 16:4 0.
