indicate that eight of twelve samples there was an excess of <br />anions over cations. Because of the high organic content of the <br />soils in the peat sites sampled, the discrepancy is attributed to <br />the presence of organic acids. The following discussion, <br />however, should be viewed with this information in mind. <br />One of the most significant findings is that at the <br />Sacramento site the downstream waters exceed the state standards <br />for several water quality constituents (see Table IV).
