<br />A review of the water year for this series of wells adjacent to the mining area indicates several
<br />maximums levels for TDS, sulfate, calcium, sodium, and magnesium occurred at GW-N16P1.
<br />Maximum levels for TDS, calcium, iron, manganese, and magnesium were also recorded at GW-
<br />N17P1. Additionally, a minimum level for sodium was recorded later in the water year at GW-
<br />N17P1. As shown on the graphs for indicator parameters, calcium, iron, and magnesium are
<br />slightly increasing at GW -17P1, and laboratory conductivity, sodium, sulfate and TDS are slight
<br />increasing at GW -N -16P 1. All the other indicator parameters track similar with sampling results
<br />indicating normal seasonal fluctuations including influences for seasonal irrigation of the
<br />reclamation areas.
