I. Ground Water:
A. Bedrock Aquifers
1. Check water levels monthly.
2. Measure field o-,a ter quality parameters monthly (pH, conduc[i vi[y,
and temperature).
3• Sample water for complete chemical analyses semi-annually.
B. Alluvial Aquifers
I. Check water levels monthly.
2. Measure field a,ater quality parameters monthly (pH, conductivity,
and temperature).
3• Sample water for complete chemical analyses quarterly.
II. Surface Water:
A. Perennial Streams
1. Measure field water quality parameters monthly (pH, conductivity,
and temperature).
2. Sample water for complete cl~emi w I analyses quarterly, especially
during high and low floo-, periods. Include floc, at time of sampling.
3. Install a continuous recording device to monitor flo~+. fieport
monthly minimum, mar.iinum, and mean flows.
B. Ephemeral Streams
I. Sample o-,ater for complete chcinical analyses l~+ice a year: once
during snovnnell, and once during a storm event. Include Flow at time
of sampling.
2. F)ow measurement c+ill be dealt o-,ith on a site-specific basis.
Consult the Division before initiating baseline studies.
