Section 1: System Description and Contact Information The US Forest Servic owns and operates one groundwater well. The water system seasonally serves up to 250 people in a given one week period and has 10 connections. Water from the well is pumped to a 20,000 gallon storage tank. Water from the tank gravity flows to our distribution system.

Our current sample schedule from Drinking Water Watch is provided in Appendix A.

SYSTEM

Special samples will be taken at the 2 sites listed in the table below which identifies the location of the Special sample and the system feature (i.e., storage tank, distribution system) the sample is associated with along with the Special sample number. These sites were chosen based on the requirements established in the seasonal start-up guidance provided by the DWB. They are also designated on the distribution system map(s) in Appendix C. We further understand that Special samples are samples collected and paid for by the water system.

Groundwater Rule (GWR) Sampling One (1) Triggered Source Water sample is required to be collected from every active well if any of our routine monthly samples test positive for Total Coliform (TC) or E.Coli (EC). These Triggered Source Water Samples will be collected directly from our well prior to any treatment and are shown on the map(s) in Appendix C. Our sample points are labeled as "Raw Water11 as shown in the photograph below.

Sampling Requirements New Mexico Regulations require that a certified sampler or certified operator collect the RTCR and GWR samples. Because of this requirement, our certified Sampler will be required to collect our bacteriological samples.

Once collected, our Sampler will submit the samples and their Chain-of Custody (CoC) forms to the following certified laboratory within 24 hours of the sample being collected:

Compliance Status

RTCR

Our water system triggers an assessment with the RTCR if:

• We get 2 TC+ samples in any one (1) month ;

• We fail to take all the required repeat samples;

• Any one (1) of these conditions will trigger a required Level 1 assessment/correction action

A Level 2 assessment/corrective action is triggered if we get:

• An EC Maximum Contaminant Level (MCL) violation; or

• An EC monitoring violation; or

• We trigger two (2) Level 1 assessments within a rolling 12 month period

GWR

We are in compliance with the GWR if our Triggered Source Water sample(s) are free of EC.

We will immediately notify our customers if any of our Triggered Source Water samples test positive for TC or EC. At that time, we can be required to conduct additional sampling, correct significant deficiencies, or disinfect our water to meet 4-log treatment requirements.

Section 3: Disinfectant Residual Monitoring Frequency We maintain a chlorinator and monitor chlorine residual.

Section 4: Lead and Copper Rule (LCR) Sampling Frequency We are not required to collect Lead and Copper samples.
