  We present the first circular polarization measurements of circumstellar
water masers around a sample of late-type stars. These observations are used to
obtain the magnetic field strength in the water maser region with both an LTE
and non-LTE analysis. We find fields from a few hundred milliGauss up to a few
Gauss, indicating a solar-type r^(-2) dependence of the magnetic field on the
distance. No linear polarization is detected to less than 1%.
