"In recent, months/* Uccora ssid, "we have received many requests for
information on the natural end man-made concentrations cl mercury in our
waters; bi.il. the'.larger question has remained: Are there- potentially dangerous
concentrations. of other elements present in our -water resources? This first
nationwide rtetirroaissence sampling was designed to provide at least.a. partial
answer - to that question."
,
He emphasized that. the values- obtained may not. be typical of the sampling sites bycgs.ye concentrations of contaminants vary signif icantly from one sampling to cn&thor for f variety of reasons, lit; also pointed out that the concenfrtv-o-is of heavy metals attributable to natural uwreos have not yet been -datam icc-id.
`
"With this end future sampling programs, we hopeto establish a continuing
baseline of inforaratior! about the quality of our surface Kid ground v'ttero to
meet our resr-oivsiblities as appraisers of the Ration's water resources/'
the purvey spykesmun said.

/`.bout 42 percent of the samples contained . cadmium in low concentrations ranging from 1 to 70 faicrograms per Titer,
and 4 percent of the water samples contained cadmium in
excess of the TO miarograras'per Titer upper limit the PHS has set for drinking water.
LEAD;
Concentrations of lead ranging from 1 to 50 micrograms per liter were found in abetsf 63 prrceot of the samples. but only
s few samples actually exceeded the 50 mi urograms per liter PHS upper-limit; for cirfnking water.
CdROPU'UM: Hexavsleat chro:riiu:n conc-fif.rav.fons in the range of G to 50 nncrogr&ns per.liter wore detected in colly 11 samples, less thnn 2 percent of ell those collected. Hone of the river
samples .contained concentrations in excess of 50 mlcrograres per liter, the Oi}jxinrns level established. by PHS for drinking
water.
COBALT.;
Cobalt vocs found in about 37 percent of the samples, usu&Hy in the range of from 1 to 5 micrograms per liter, l(o tsaxlmunt
eonce.ntrution limit has yet been set by PHS for cobalt In drinking water,
ZTM:
.Zinc is a fairly soluble n&tnl and concentrations range widely in river water's. It was detected most ccfnWy in the range of 10 ic 50 inleroermB per liter, but occasions]ly ereseded 5,000 micrograms per liter, the revc:rt;vr:d. (but not re31vj.st.cry)
